The outer wall of the spiral spring 222 is fixedly connected to the sleeve 221. The sleeve 221 contains a... A limiting component is provided; wherein, the limiting component is located outside the connecting block 212, and includes a ratchet 223 fixedly connected to the outer wall of the connecting block 212; a locking block 224 is slidably connected to the inner wall of the sleeve 221, the locking block 224 is adapted to the ratchet 223, the outer wall of the locking block 224 is slidably connected to the slider 321, and the side of the locking block 224 near the slider 321 is fixedly connected to the spring 322; the spring-rebound assembly 23 includes a limiting rod 231 fixedly connected to the bottom of the clamp 102; and the worktable 101... A spring 232 is fixedly connected to the bottom inner wall, and an abutment block 233 is fixedly connected to the top of the spring 232. The outer wall of the abutment block 233 is slidably connected to the worktable 101, and the top of the abutment block 233 abuts against the limit rod 231. The abutment block 233 is a square block. By setting the mounting part 2, the fixture 102 can be installed on the worktable 101 with simple operation, without the need for the operator to spend a lot of time operating it, thereby shortening the production preparation time and improving production efficiency.

[0028] The auxiliary part 3 includes a synchronization component 31, which is located below the worktable 101; and two elastic components 32, both located at the bottom of the worktable 101. The two elastic components 32 are mirror images of each other. The synchronization component 31 includes a connecting block 311 fixedly connected to the bottom of the worktable 101. A rotating shaft 312 is rotatably connected to the inner wall of the connecting block 311. A transmission component is located within the connecting block 311. The connecting block 311 is an inverted C-shaped block. The transmission component includes a gear 313 fixedly connected to the outer wall of the rotating shaft 312, through which the rotating shaft 312 passes. Two racks 314 are slidably connected to the inner wall of the connecting block 311, and both racks 314 are connected to the gear 312. The two racks 314 are engaged in a three-phase meshing manner, with their opposite sides fixedly connected to the two sliders 321. The two racks 314 are circumferentially distributed.

When disassembly is required, the locking blocks 224 on both sides can be unlocked simultaneously, making the use of the device more convenient.

[0029] A specific application of this embodiment is as follows: In use, the rotating shaft 312 can be rotated to drive the gear 313 to rotate. When the gear 313 rotates, it will drive the two racks 314 to move closer together, thereby driving the two sliders 321 to move closer together, thereby causing the spring 323 to stretch and generate elastic force. At this time, the two sliders 321 will drive the two locking blocks 224 to move away from the two ratchet gears 223 respectively. At this time, the connecting block 212 will lose its restraint, thereby driving the connecting block 212 to rotate under the action of the spiral spring 222. 2. During rotation, the limiting rod 211 will be squeezed out of the connecting block 212 by the spiral groove 213 and the spiral block 214. During this process, the limiting rod 231 will move upward by the abutment block 233 under the elastic force of the spring 232, thereby pushing the clamp 102 out of the worktable 101, so that the clamp 102 can be removed. After the clamp 102 is removed, the rotating shaft 312 can be released. At this time, the synchronous component 31 will be reset by the slider 321 under the elastic force of the spring 323. When installation is required, The clamp 102 is inserted into the worktable 101 via the limiting rod 231. Then, the clamp 102 is pressed, causing it to press against the abutment block 233. This compresses the spring 232, generating elastic force. Simultaneously, pressing the clamp 102 causes the limiting rod 211 to slide into the connecting block 212. At this time, the spiral block 214 slides into the spiral groove 213, and under its action, drives the connecting block 212 to rotate. When the connecting block 212 rotates, the spiral spring 222 contracts and generates elastic force. The rotation of the connecting block 212 also causes... The ratchet 223 rotates, thereby squeezing the locking block 224 and causing it to slide into the slider 321. When the limiting rod 211 is fully slid into the connecting block 212, the connecting block 212 will stop rotating. When the connecting block 212 stops rotating, the locking block 224 will lock the ratchet 223. When the locking block 224 slides into the slider 321, it will squeeze the spring 322, compressing it and generating elastic force. When the ratchet 223 stops rotating, the elastic force of the spring 322 will drive the locking block 224 to lock the ratchet 223.
