Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0033] like Figure 1 As shown in the figure, an embodiment of this utility model provides a simple tooling for removing a locating pin, comprising: a crossbeam 5, a sliding rod, a hammer head 4, a chuck 6, and a clamping mechanism; the crossbeam 5 can be a circular rod structure to facilitate the mounting of the chuck 6. The sliding rod includes: a sliding rod 2 and a sliding rod 1; one end of the sliding rod 2 is detachably and vertically disposed in the middle of the crossbeam 5, and the sliding rod 2 and the crossbeam 5 can be connected by threads for easy disassembly, carrying, and maintenance. One end of the sliding rod 1 is fixedly disposed at the other end of the sliding rod 2, and is coaxially disposed with the sliding rod 2; the sliding rod 2 and the sliding rod 1 can be integrally disposed. The hammer head 4 is mounted on the sliding rod 1 and can slide relative to the sliding rod 1; the other end of the sliding rod 1 is detachably provided with a locating block 3; the locating block 3 is preferably connected to the other end of the sliding rod 1 by threads. By applying a vertically upward impact force along the sliding rod 1 with the hammer head 4, the crossbeam 5 and the locating pin move synchronously, completing the disassembly.

[0034] The chuck 6 includes a connecting portion 6-1, an extension portion 6-2, and a locking portion 6-3. The connecting portion 6-1 has a through hole. The through hole of the connecting portion 6-1 is fitted onto the crossbeam 5 and can slide along the crossbeam 5. One end of the extension portion 6-2 is fixedly disposed on the connecting portion 6-1. The locking portion 6-3 is fixedly disposed on the other end of the connecting portion 6-1. The locking portion 6-3 maintains a predetermined distance from the connecting portion 6-1 so that the locking portion 6-3 can be locked at appropriate positions on both sides of the positioning pin. The locking portion 6-3 extends from the extension portion 6-2 toward the middle of the crossbeam 5. There are two chucks 6. The two chucks 6 are symmetrically distributed with the slide bar 1 as the center. The extension portions 6-2 on the two chucks 6 are respectively provided with threaded holes 12 and connecting holes 13. The threaded holes 12 and connecting holes 13 are coaxially arranged.
