The receptacle further includes a coupling section, a receiving section, and a shoulder between the coupling section and the receiving section. A work rod includes first and second work sections respectively having first and second work ends of different sizes. An insertion section between the first and second work sections includes first and second stop faces. One of the first and second work sections of the work rod is selectively inserted into the receiving section of the receptacle and is positioned by a positioning device. The insertion section is received in the coupling section. The other of the first and second work sections is exposed. One of the first and second stop faces abuts the shoulder of the receptacle to form a path for a force transmitted in an axial direction. ## Claims ### Claim 1 A tool comprising: a main rod including a front end having a receptacle extending in an axial direction, with the main rod further including a holding portion on an outer side thereof, with the receptacle including an opening in the front end, with the receptacle further including a coupling section extending rearwards from the opening in the axial direction, with the receptacle further including a receiving section extending rearwards from the coupling section in the axial direction, with a shoulder formed between the coupling section and the receiving section, with an inner diameter of the shoulder being smaller than an inner diameter of the coupling section; a work rod including first and second work sections respectively on two ends thereof, with the first work section including a first work end, with the second work section including a second work end having a size different from a size of the first work end, with the work rod further including an insertion section between the first and second work sections, with the insertion section having a maximum diameter larger than diameters of the first and second work sections, with the insertion section including a first stop face facing the first work section and a second stop face facing the second work section, with the maximum diameter of the insertion section being slightly smaller than the inner diameter of the coupling section of the main rod, with the coupling section preventing rotation of the work rod while the work rod is being inserted into the coupling section, and with each of the first and second work sections having a length in the axial direction smaller than a length of the receiving section of the main rod in the axial direction; and a positioning device configured to position the work rod relative to the main rod, wherein one of the first and second work sections of the work rod is selectively inserted into the receptacle of the main rod and is positioned by the positioning device, the one of the first and second work sections of the work rod is received in the receiving section, the insertion section of the work rod is received in the coupling section, another of the first and second work sections of the work rod is exposed, and one of the first and second stop faces abuts the shoulder of the receptacle to form a path for a force transmitted in the axial direction. ### Claim 2 (depends on 1) The tool as claimed in claim 1, wherein each of the coupling section of the receptacle of the main rod and the insertion section of the work rod is polygonal. ### Claim 3 (depends on 1) The tool as claimed in claim 1, wherein the insertion section has a length in the axial direction larger than the length of the coupling section in the axial direction. ### Claim 4 (depends on 1) The tool as claimed in claim 1, wherein the positioning device is provided on the work rod, and wherein the positioning device is received in the coupling section of the receptacle when the work rod engages with the main rod. ### Claim 5 (depends on 4) The tool as claimed in claim 4, with the insertion section of the work rod including a radial hole having an opening, with a diameter of the opening of the radial hole being lightly smaller than an inner diameter of the radial hole, with the positioning device including a spring and a ball, with the spring and the ball received in the radial hole, and with the ball biased by the spring to partially protrude outside of the opening of the radial hole. ### Claim 6 (depends on 1) The tool as claimed in claim 1, wherein each of the first and second work ends of the work rod has a shape corresponding to a nail head. ### Claim 7 (depends on 1) The tool as claimed in claim 1, wherein each of the first and second work ends of the work rod has a pointed shape. ### Claim 8 (depends on 1) The tool as claimed in claim 1, wherein each of the first and second work ends of the work rod has a keystone tip, a Phillips head tip, or a polygonal tip. ### Claim 9 (depends on 4) The tool as claimed in claim 4, with the insertion section of the work rod further including a first and second recessed sections, with the first recessed section located between the positioning device and the first stop face, with the second recessed section located between the positioning device and the second stop face, and with one of the second and first recessed sections exposed outside of the main rod when one of the first and second work sections is received in the receiving section of the receptacle of the main rod.
