  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, FIG. 1 to FIG. 6 will be referred to. The bending mechanism for a hand tool according to an embodiment of the present invention includes a rod 1 and at least one bending portion 2. A hand tool according to an embodiment of the present invention includes the hand tool bending mechanism and the claw wheel head 3.

  Please refer to FIGS. 1 to 3A and 3B. In this embodiment, the rod 1 has both ends, a working part 12 is formed at one end, and a grip part 11 is formed at the other end. The bent portion 2 includes a pivot groove 21 and a turning end 22 and is provided between the working portion 12 and the grip portion 11. The pivot end 22 is assembled in the pivot groove 21. The pivot groove 21 has a groove 211 and a restriction structure. The turning end 22 has a slide groove 221 and can be switched between a first position and a second position. When the turning end 22 is located at the first position, the turning end 22 cannot turn with respect to the work unit 12 due to the restriction structure. When the turning end 22 is located at the second position, the turning end 22 can turn into the groove 211 to make the rod 1 L-shaped.

  A recess 212 is formed at the bottom of the pivot groove 21. When the turning end 22 is located at the first position, the turning end 22 contacts the recess 212. The restricting structure includes engaging stairs 213 and 213 ′ facing each other and side surfaces 214 and 214 ′ facing each other. A stereotaxic hole 215 is formed on the side surface 214 and a stereotactic groove 216 is formed on the side surface 214 ′. An opening 217 having a U-shape is formed in the axial direction of the wall surface of the pivot groove 22, and the opening 217 and the groove port 211 communicate with each other. The side surfaces 214 and 214 'are located on both sides adjacent to the opening 217 in the wall surface. When the turning end 22 is turned, the turning end 22 is engaged with the opening 217.

  Please refer to FIG. 2A and FIG. 2B. Contact surfaces 222 and 222 ′ are formed on the peripheral surface of the turning end 22. When the turning end 22 is located at the first position, the contact surfaces 222 and 222 ′ contact the engagement steps 213 and 213 ′, respectively. Thus, the grip part 11 cannot turn with respect to the work part 12. The turning end 22 further has a receiving hole 223. The accommodation hole 223 corresponds to the stereotaxic groove 216. The slide groove 221 corresponds to the stereotaxic hole 215. The bent portion 2 further includes a localization unit, and the localization unit includes a first elastic tool 224, a second elastic tool 225, a first localization tool 226, and a second localization tool 227. The first localization tool 226 can move in the slide groove 221. When the turning end 22 is located at the first position, the first positioning tool 226 is located at one end of the slide groove 221. When the turning end 22 is located at the second position, the first positioning tool 226 is located at the other end of the slide groove 221. Refer to FIG. 3 and FIG. The first elastic tool 224, the second elastic tool 225, and the second localization tool 227 are accommodated in the accommodation hole 223. The second localization tool 227 is disposed between the first elastic tool 224 and the second elastic tool 225. The first localization tool 226 is disposed between the slide groove 221 and the localization hole 215. The first localization tool 226 and the second localization tool 227 are preferably balls.

  The accommodation hole 223 has a step surface 2231. The first elastic member 224 has one end pressed against the step surface 2231 and the other end pressed against the side surface 214 ′ of the localization groove 216. Thus, the turning end 22 can be stably positioned at the first position or the second position.

  Refer to FIG. 3B. When the turning end 22 is located at the first position, the second positioning tool 227 is positioned below the positioning groove 216, is received in the receiving hole 223, presses the second elastic tool 225, and the first The positioning tool 226 is located at one end of the slide groove 221 close to the working portion 12, and the first elastic tool 224 continuously presses against the side surface 214 ′ of the positioning groove 216. Thus, the turning end 22 can be stably disposed in the pivot groove 21 and abuts on the recess 212. Further, the abutting surfaces 222 and 222 ′ abut on the engaging steps 213 and 213 ′, respectively, so that the turning end 22 cannot turn in any direction. Please refer to FIG. 4A and FIG. 4B. When the pivot end 22 is located at the second position, the pivot end 22 is separated from the depression 212 of the pivot groove 21, the contact surfaces 222 and 222 ′ are also separated from the engagement steps 213 and 213 ′, and the first The localization tool 226 moves up according to the turning end 22. At this time, the second positioning tool 227 is pressed against the receiving hole 223 by the second elastic tool 225, and when the second positioning tool 227 moves to the positioning groove 216, the second positioning tool 227 is pressed against the positioning groove 216 and engaged. Stopped. Thereby, the turning end 22 cannot be moved further upward and is fixed at the second position. Please refer to FIG. When the turning end 22 is positioned at the second position, the first positioning tool 226 moves from one end of the slide groove 221 close to the working portion 12 to one end close to the recess 212 of the slide groove 221.

  Please refer to FIG. 4A, FIG. 4B and FIG. When the turning end 22 is fixed at the second position, the grip portion 11 can turn with respect to the turning end 22, whereby the grip portion 11 is perpendicular to the working portion 12. At this time, the turning end 22 is engaged with the opening 217. Since the wall surface of the pivot groove 21 corresponds to one side of the opening 217 and exhibits a closed state, the turning end 22 can only turn to the opening 217. In the above embodiment, the first localization tool is provided on one side of the localization hole, and the second localization tool is provided on one side of the localization groove. However, the present invention is not limited thereto. The first localization tool may be provided on one side of the localization groove, and the second localization tool may be provided on one side of the localization hole.
