and, the socket extension bar has a predetermined length, and, at least a small portion of the socket extension bar is exposed outside of the hollow portion of said wrench handle while said socket extension bar is substantially housed and detachably secured therein to facilitate insertion and removal of said socket extension bar into and out of the hollow portion of said wrench handle by a user. ### Claim 4 (depends on 2) The wrench handle of claim 2 wherein each of all four walls surrounding the square shaped opening at the front part of the hollow portion of said wrench handle is notched to receive the spring-loaded ball of the driving member of said socket extension bar to detachably secure the socket extension bar within the hollow portion of said wrench handle. ### Claim 5 (depends on 1) The wrench handle of claim 1 wherein the hollow portion of said wrench handle has a predetermined length; and, the socket extension bar has a predetermined length, and, a small portion of the socket extension bar is exposed outside of the hollow portion of said wrench handle while said socket extension bar is substantially housed and detachably secured therein to facilitate insertion and removal of said socket extension bar into and out of the hollow portion of said wrench handle by a user. ### Claim 6 A wrench comprising a wrench head and handle; said wrench head comprising a driving member formed having a predetermined configuration; and, said wrench handle being elongated in a predetermined direction and having at least a portion thereof being substantially hollow, said hollow portion having a front part and a rear part, the front part of said hollow portion being formed having a substantially square shaped opening being surrounded by four walls extending in the direction of which said handle is elongated, said square shaped opening further being formed to receive a driving member of a socket extension bar having a similar square shape when viewed from an end-view thereof, the rear part of the hollow portion of said handle having a distal open end, whereby, the socket extension bar may be inserted into the rear part of said hollow portion of said handle with the driving member of said socket extension bar entering into the square shaped opening at the front part of the hollow portion of said wrench handle, whereby, said socket extension bar may be substantially housed and detachably secured within the hollow portion of said wrench handle. ### Claim 7 (depends on 6) The wrench of claim 6 wherein the socket extension bar has a spring-loaded ball protruding from the driving member thereof, and at least one of the four walls surrounding the square shaped opening at the front part of the hollow portion of said wrench handle is notched to receive the spring-loaded ball of the driving member of said socket extension bar to detachably secure the socket extension bar within the hollow portion of said wrench handle. ### Claim 8 (depends on 7) The wrench of claim 7 wherein the hollow portion of said wrench handle has a predetermined length; and, the socket extension bar has a predetermined length, and, at least a small portion of the socket extension bar is exposed outside of the hollow portion of said wrench handle while said socket extension bar is substantially housed and detachably secured therein to facilitate insertion and removal of said socket extension bar into and out of the hollow portion of said wrench handle by a user. ### Claim 9 (depends on 7) The wrench of claim 7 wherein each of all four walls surrounding the square shaped opening at the front part of the hollow portion of said wrench handle is notched to receive the spring-loaded ball of the driving member of said socket extension bar to detachably secure the socket extension bar within the hollow portion of said wrench handle. ### Claim 10 (depends on 6) The wrench of claim 6 wherein the hollow portion of said wrench handle has a predetermined length; and, the socket extension bar has a predetermined length, and, at least a small portion of the socket extension bar is exposed outside of the hollow portion of said wrench handle while said socket extension bar is substantially housed and detachably secured therein to facilitate insertion and removal of said socket extension bar into and out of the hollow portion of said wrench handle by a user. ### Claim 11 (depends on 6) The wrench of claim 6 wherein the driving member of the wrench head is similar in size and configuration to the driving member of said socket extension bar. ### Claim 12 A combination of a socket extension bar and a ratchet wrench, said combination comprising: said socket extension bar being elongated having two ends with a head at one end and a driving member at the other end thereof, the head having a cavity formed therein with a predetermined configuration, the driving member being formed with a predetermined configuration, said socket extension bar further having predetermined length and width dimensions; and, said ratchet wrench having a wrench head and handle; said wrench head comprising a ratcheting mechanism and a driving member formed with a predetermined configuration; said wrench handle being elongated in a predetermined direction and having at least a portion thereof being substantially hollow, said hollow portion having a front part and a rear part, the front part of said hollow portion being formed having a substantially square shaped opening surrounded by four walls extending in the direction of which said handle is elongated, said square shaped opening further being formed to receive the driving member of said socket extension bar, the rear part of the hollow portion of said handle having a distal open end, whereby, the socket extension bar may be inserted into the rear part of the hollow portion of said handle with the driving member of said socket extension bar entering into the square shaped opening at the front part of the hollow portion of said wrench handle, whereby, said socket extension bar may be substantially housed and detachably secured within the hollow portion of said wrench handle. ### Claim 13 (depends on 12) The combination of a socket extension bar and a ratchet wrench of claim 12 wherein the predetermined configuration of the cavity in the head of the socket extension bar and the predetermined configuration of the driving member of said ratchet wrench head are each formed to interlock with the other, whereby, the ratchet wrench may control rotation of the socket extension bar. ### Claim 14 (depends on 12) The combination of a socket extension bar and ratchet wrench of claim 12 wherein at least a small portion of the socket extension bar is exposed outside of the hollow portion of said wrench handle while said socket extension bar is substantially housed and detachably secured therein to facilitate insertion and removal of said socket extension bar into and out of the hollow portion of said wrench handle by a user. ### Claim 15 (depends on 14) The combination of a socket extension bar and a ratchet wrench of claim 14 wherein the entire head of the socket extension bar is substantially exposed outside of the hollow portion of the ratchet wrench handle when said socket extension bar is housed and secured within the hollow portion of said wrench handle. ### Claim 16 (depends on 12) The combination of a socket extension bar and a ratchet wrench of claim 12 wherein the socket extension bar has a spring-loaded ball protruding from the driving member thereof, and at least one of the four walls surrounding the square shaped opening at the front part of the hollow portion of said wrench handle is notched to receive the spring-loaded ball of the driving member of said socket extension bar to detachably secure the socket extension bar within the hollow portion of said wrench handle. ### Claim 17 (depends on 16) The combination of a socket extension bar and a ratchet wrench of claim 16 wherein each of all four walls surrounding the square shaped opening at the front part of the hollow portion of said wrench handle is notched to receive the spring-loaded ball of the driving member of said socket extension bar to detachably secure the socket extension bar within the hollow portion of said wrench handle. ### Claim 18 (depends on 12) The combination of a socket extension bar and a ratchet wrench of claim 12 wherein the driving member of the wrench head is similar in size and configuration to the driving member of said socket extension bar.
