As further shown in Figures 2, 3 and 4, it is worth specifically explaining that the fixing mechanism 4 includes four limiting slide grooves 401, and the four limiting slide grooves 401 are cross-shaped and opened on the top surface of the platform body 1. The limiting slide grooves 401 are slidably connected to the limiting blocks 408, the top of the limiting blocks 408 is fixedly connected to the clamping plate 402, the bottom of the inner side of the limiting blocks 408 is fixedly connected to the connecting plate 403, the connecting plate 403 is hinged with a connecting rod 409, the other end of the connecting rod 409 is rotatably connected to a hinged rod 4110, the top of the hinged rod 4110 is fixedly connected to a rotating disk 4111, and the rotating disk 4111 A fixed shaft 4112 is rotatably connected in the middle, two bottoms of the four limit blocks 408 that are opposite to each other are respectively fixedly connected to a connecting plate 407, a bidirectional threaded rod 406 is threadedly connected to the connecting plate 407, a worm gear 405 is fixedly connected in the middle of the bidirectional threaded rod 406, a first motor 404 is fixedly connected to the worm gear 405, the first motor 404 is fixedly installed at the bottom of the platform 1, the top of the fixed shaft 4112 is fixedly connected to the top of the platform 1, the connecting rod 409 is L-shaped, and is rotatably arranged around the center of the fixed shaft 4112 on the four connecting plates 403;

The first motor 404 is operated to drive the worm gear 405 to rotate, driving the bidirectional threaded rod 406 to rotate, thereby moving the connecting plate 407, so that the limit block 408 slides in the limit slide groove 401, and at the same time pushes the connecting rod 409 to move. Since the connecting rod 409 is hinged to the connecting plate 403 and is rotationally connected to the rotating disk 4111 through the hinged rod 4110, the rotating disk 4111 rotates on the fixed shaft 4112, so that the four limit blocks 408 slide synchronously in the limit slide groove 401, and then the clamping plate 402 clamps the parts around, making the fixation stable, thereby ensuring the stability of the processing work.
