[0027] When the leg plate joint pin is processed, it needs to be positioned by a tool before processing, when using the device, multiple groups of multi-hole tooling 2 can be prepared for alternate use, for example, the user first rotates the lead screw to make the limiting plate 4 connected with the lead screw start to move, until the distance between the two limiting plates 4 is suitable for the multi-hole tooling 2 to be positioned, after completing the debugging, the user moves the multi-hole tooling 2 in which the leg plate joint pin is placed to the top of the mounting frame 1 between the two limiting plates 4, then the user controls the electromagnet 505 to be de-energized, so that the electromagnet 505 on the clamping block 503 is not affected by the magnetic field and is pushed by the return spring 504 to make the clamping block 503 clamped into the clamping groove 502, thereby completing the positioning of the multi-hole tooling 2, then the user pulls the synchronous plate 702 upwards to make the positioning pin 10 extracted from the positioning groove 11, and the compression spring 703 is compressed and generates an opposite force, the user can move the movable frame 701 to make the synchronous plate 702 move to the top of the leg plate joint pin, then the user releases the synchronous plate 702 to make the compression spring 703 exert a spring force on the synchronous plate 702, and the synchronous locking of the synchronous plate 702 and the multiple leg plate joint pins can be realized in cooperation with the multiple matching grooves 8 and the anti-skid convex points, then the processing can be carried out, after the leg plate joint pin in the multi-hole tooling 2 is processed, the user controls the electromagnet 505 to be energized, and the electromagnet 505 generates magnetism to attract the metal sheet, at this time, the magnetic force is greater than the force of the return spring 504, so that the clamping block 503 gradually moves towards the inside of the mounting seat 501 until it is separated from the clamping groove 502, then the multi-hole tooling 2 between the limiting plates 4 can be extracted and replaced with the assembled multi-hole tooling 2, when different leg plate joint pins are processed, the specifications of the multi-hole tooling 2 are different, and the user can adjust the distance between the limiting plates 4 through the lead screw to adapt to different multi-hole tooling 2.
