At the same time, the movement of the adjusting plate can be limited and buffered through the buffer spring and the buffer plate, which is convenient for the movement of the adjusting plate. However, there will still be a problem that the existing technology cannot adjust the height of the clamping position, resulting in a relatively single clamping position for automotive parts and having certain limitations.

[0008] According to different processing requirements of automotive parts, by manually rotating the lead screw, the movable frame and the connecting frame can be driven to move upward, so that the heights of the first clamping plate and the second clamping plate can be adjusted simultaneously. And by manually rotating the screw rod, the connecting block can be driven to move upward, and the connecting frame can be synchronously driven to move upward to adjust the distance between the connecting frame and the movable frame, so as to realize the adjustment of the position where the first clamping plate and the second clamping plate clamp the automotive parts, thereby expanding the clamping range and facilitating the subsequent processing of different positions of the automotive parts; during the process of clamping the automotive parts by the first clamping plate and the second clamping plate, after one processing is completed, the user can use the pushing component and the limiting component to move the first clamping plate or the second clamping plate respectively, so that the first clamping plate or the second clamping plate is separated from the automotive parts, so as to facilitate the adjustment of the position of the first clamping plate or the second clamping plate alone, and avoid the surface of the automotive parts in contact with the first clamping plate or the second clamping plate from being worn due to the sliding of the first clamping plate or the second clamping plate along the automotive parts, thus playing a protective effect on the automotive parts.
