Abstract
This invention discloses a sectional adjustable socket tool handle, which controls the movement of an axial rod along the axial direction of an external pipe by a connecting measure, and comprises a plurality of grooves, a coupler for engaging the plurality of grooves, such that a latch member on the external pipe is latched into the groove under normal conditions, and the coupler can move between a first position and a second position along the axial direction of the external pipe. When the coupler moves to the first position, the coupler will press against the latch member to prevent the axial rod from moving. When the coupler moves to the second position, the coupler will release the latch member. Such arrangement can provide a safe and reliable socket wrench.
Claims10
A sectional adjustable socket tool handle, having an axial rod and an external pipe for controlling an axial movement of said axial rod inside said external pipe by a connecting measure, comprising:
- a through hole, disposed at an end of said axial rod for receiving a resilient member, and said resilient member having two latch members on both ends, a second circular groove disposed on an inner wall of said external pipe, so that the tension of said resilient member pushing said latch member into said circular groove when said axial rod extending outward to a maximum distance along the axial direction of said external pipe;
- a plurality of grooves disposed around said axial rod and a plurality of apertures disposed around the top of said external pipe and said latch member being disposed at said aperture for latching said groove when said axial rod moving along the axial direction of said external pipe;
- and
- a coupler being a movable hollow pipe installed at the top of said external pipe and surrounding said plurality of apertures for accommodating a resilient member therein, such that an end of said resilient member being fixed into a first circular groove and the other end pressing against a blocking section of said coupler;
- said coupler has a compression section and a releasing section, and when said latch member being latched into said groove under normal condition, said coupler moving between a first position and a second position along the axial direction of said external pipe, and when said coupler moving to said first position, said compressing section pressing against said latch member, and when said coupler moving to said second position, said releasing section releasing said latch member.
