At this time, the squeezing plate 308 drives the second protection pad 319 to move in the direction close to the special-shaped surface of the object. At this time, the second protection pad 319 made of rubber can protect the special-shaped surface of the object. Then the squeezing plate 308 drives one end of the first spring 317 to move, and at the same time, the first spring 317 itself will generate a retracting pulling force. At this time, the first spring 317 can help the squeezing plate 308 to quickly reset. The clamping device 3 is arranged, and the mutual cooperation among the groove 301, the bidirectional screw rod 302, the screw block 303, the movable plate 304, the connecting rod 305, the arc plate 306, the connecting shaft 307, the extrusion plate 308, the hydraulic rod 309, the push block 310, the fixed plate 311, the slide bar 312 and the limit block 313 can be used to increase the contact area with the special-shaped surfaces of objects of different specifications, avoid the situation that the contact area between the fixture and the special-shaped surface of the object is too small due to the contact with the special-shaped surface of the object, resulting in insufficient stability during clamping and fixing, causing it to fall off during processing, thereby increasing the contact area between the fixture and the special-shaped surface of the object, and further improving the stability of the fixture.

[0036] When it is necessary to rotate the bidirectional screw rod 302, it is only necessary to move the turning handle 44 in the direction close to the circular plate 41, and then the turning handle 44 will drive the rectangular rod 43 to move in the direction close to the rectangular groove 42, and at the same time the rectangular rod 43 will drive the pointed cone 45 to move in the same direction. At this time, the trapezoidal pointed cone 45 can facilitate the rectangular rod 43 to enter the rectangular groove 42, and then the turning handle 44 will drive one end of the second spring 46 to move, and at the same time the second spring 46 itself will generate an outward elastic force. At this time, the second spring 46 can connect the turning handle 44 and the circular plate 41 to prevent the turning handle 44 from being lost. When the rectangular rod 43 is inserted into the rectangular groove 42, the turning handle 44 is turned. At this time, the turning handle 44 will drive the rectangular rod 43 to rotate, and then the rectangular rod 4 3 will drive the rectangular slot 42 to rotate, and then the rectangular slot 42 will drive the circular plate 41 to rotate, at this time the circular plate 41 will drive the bidirectional screw rod 302 to rotate, when the rotation is completed, release the turning handle 44, the spring will use its own elastic force to pop out the turning handle 44 in the direction away from the circular plate 41, at this time the turning handle 44 will drive the rectangular rod 43 to pop out from the rectangular slot 42, by setting the auxiliary device 4, using the cooperation between the circular plate 41, the rectangular slot 42, the rectangular rod 43 and the turning handle 44, it can be achieved that when the clamp clamps the special-shaped surface of the object, the bidirectional screw rod 302 is affected by the external force and rotates, avoiding the situation that the clamp becomes loose, which leads to errors in the processing of the object, improves the stability of the clamp clamping, and further improves the efficiency of the processing.
