Finally, the flange plate is placed among the three claws 120, the driving rod 221 is rotated, so that the driving rod 221 drives the driving bevel gear 220 to rotate, and the driving bevel gear 220 is engaged with teeth of the driving disk 210, so that the driving disk 210 is driven by the driving bevel gear 220 to rotate, the claws 120 move in the direction of abutting against the flange plate under the action of the spiral grooves 211 of the driving disk 210, and the fixation of the flange plate is realized.

Example two

Referring to fig. 4 and 5, the present embodiment is different from the first embodiment in that: the dust-proof block 300 is provided with three sliding grooves 330 along the radial direction of the disc body 110. The locking assembly 400 includes a sliding block 430 and a positioning spring 440, the sliding block 430 is adapted to the shape of the sliding slot 112, and the sliding block 430 is slidably connected to the sliding slot 330 and the sliding slot 112 along the length direction of the sliding slot 330. The positioning spring 440 is disposed in the sliding groove 330 along the length direction of the sliding groove 330, and one end of the positioning spring 440 is fixedly connected to the side wall of the sliding groove 330, and the other end is fixedly connected to the sliding block 430. The sliding block 430 is located at a connection position of the sliding groove 330 and the sliding slot 112 by the elastic force of the positioning spring 440. In order to facilitate the sliding block 430 to slide into the sliding groove 112, one end of the sliding block 430 close to the claw 120 is chamfered.

In order to prevent the scraps generated during the machining of the workpiece from entering the sliding groove 330 and affecting the sliding of the sliding block 430, the dust-proof block 300 has a receiving cavity 340 communicating with the sliding groove 330. A rotating roller 341 is rotatably attached to a side wall of the accommodating chamber 340. The rotating rollers 341 are arranged in a direction perpendicular to the disk surface of the disk body 110. Three pieces of dust-proof cloth 342 are fixed and wound around the rotating roller 341. The dust cloth 342 corresponds to the sliding blocks 430 one by one, and the end surface of the dust cloth 300 close to the fixture block 113 is provided with a communication hole 344 for the dust cloth 342 to pass through. One end of the dust cloth 342 far away from the rotating roller 341 passes through the communication hole 344 and then is fixedly connected with the corresponding slide block 430.

In order to facilitate the rotation of the rotating roller 341 to tighten the dust cloth 342 and to retract the sliding block 430, one end of the rotating roller 341 near the pawl 120 penetrates the accommodating chamber 340.
