One end of the movable push rod 602 is connected to one side of the fixed plate 601, and the other end of the movable push rod 602 is connected to one side of the push plate 603.

[0022] The specific implementation method is as follows: by setting up the adaptive clamping component 6, the movable push rod 602 drives the push plate 603 and multiple clamping and bonding plates 604 to approach the workpiece simultaneously to achieve rapid initial clamping and positioning. Then, by manually adjusting the rotary knob, the moving screw 605 is driven to push each clamping and bonding plate 604 to move independently and accurately, so as to achieve adaptive bonding of each surface of the irregular workpiece. This not only improves the clamping efficiency but also significantly enhances the clamping stability and accuracy. At the same time, the second telescopic rod 607 is used to enhance the movement stability of the clamping and bonding plates 604 and avoid skewing. Finally, while ensuring clamping efficiency, the clamping adaptability and reliability of complex-shaped workpieces are greatly improved.

[0023] Working Principle: During use, the operator opens the protective sliding door 3, opening the main frame 1. Then, the operator activates the electric push rod 501, which moves the movable support platform 502 outwards. During this process, the movable support platform 502 moves the support connecting rod 503, which in turn moves the movable rack 511 vertically. Simultaneously, the movable rack 511 moves the limiting rack 505 to one side. The limiting rack 505 is reset by the support spring 509 and can unidirectionally limit the movable rack 511, preventing it from falling. This allows the support connecting rod 503 to provide lateral support to the movable support platform 502. The support ensures the overall support performance and stability of the movable support platform 502 after it is moved horizontally. Then, the worker secures the workpiece to the movable support platform 502 using the adapter clamping assembly 6. The worker pulls the locking knob 506 to one side, which moves the limiting rack 505, causing the limiting rack 505 to separate from the moving rack 511. Then, the worker rotates the locking knob 506, which makes the locking knob 506 fit tightly against one side of the connecting frame 507. Under the action of friction, the position of the limiting rack 505 is locked, so that the limiting rack 505 no longer limits the moving rack 511, ensuring the smooth reset of the moving rack 511. When clamping and limiting the workpiece, the operator places the workpiece on the movable support platform 502 using external equipment. Then, the movable push rod 602 drives the push plate 603 to move, which in turn drives multiple clamping and bonding plates 604 to move, bringing the clamping and bonding plates 604 closer together and initially clamping and limiting the workpiece. Afterward, the operator turns the rotary knob, which drives the movable lead screw 605 to rotate. The movable lead screw 605 drives the lead screw seat 606 to move, which in turn drives the clamping and bonding plates 604 to move. This allows the position of each clamping and bonding plate 604 to be finely adjusted to fit and bond to different surfaces of the workpiece, thereby improving the clamping effect.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
