The driving assembly 3 is installed on the mounting plate 1 and the mounting frame 21, the driving component 3 is used to drive the clamping claw mounting plates 24 on all the clamping components 2 to synchronously approach or move away from the center point of the mounting plate 1, and the connecting member 6 is installed on the top of the mounting plate 1. When in use, the clamping claw mounting plates 24 and the clamping claws 25 on all the mounting frames 21 are driven by the driving component 3 to approach the center of the mounting plate 1, so as to achieve the clamping of the object. Through the provided position adjustment unit, the mounting frame 21 can slide and adjust the position on the annular slide rail 4 through the sliding seat 213. After adjusting to the appropriate position, it is fixed by the locking member 5, which is convenient for adjusting the position of the clamping claw mounting plate 24 and the clamping claw 25, so that the position of the clamping claw mounting plate 24 and the clamping claw 25 can be adjusted arbitrarily to adapt to the clamping of different types of objects, and the applicability is high.
[0029] In this embodiment, if Figure 1 and Figure 4 As shown, the locking member 5 includes a locking bolt 51 and a locking block 52.

[0037] In this embodiment, if Figure 1 As shown, the connecting member 6 includes a protective frame 61 which is sleeved on the outside of the driving member 31. The protective frame 61 is fixedly connected to the top of the mounting plate 1. A mounting seat 62 is fixedly connected to the top of the protective frame 61. The protective frame 61 is used to protect the driving member 31. The mounting seat 62 facilitates the installation of the clamping device in the use position.
[0038] Working principle: When in use, the driving member 31 drives the lifting seat 32 to move downward, and the lifting seat 32 drives the support rod 33 to move downward synchronously to adjust the inclination angle of the linkage push rod 35, driving the first limit slide 23 to slide and adjust the position on the first guide rod 22, driving the clamping claw mounting plate 24 and the clamping claw 25 on all the mounting frames 21 to approach the center of the mounting plate 1 to achieve the clamping of the object. When clamping different types of objects, the locking bolt 51 is loosened to separate the clamping block 52 from the inner wall of the annular receiving groove 11, thereby releasing the locking and fixing effect of the mounting frame 21, and the mounting frame 21 can be moved by sliding The movable seat 213 slides on the annular slide rail 4 to adjust the position of the clamp mounting plate 24 and the clamp 25. After the mounting frame 21 is adjusted to a suitable position, the locking bolt 51 is tightened to drive the clamping block 52 to press against the inner wall of the annular receiving groove 11, thereby locking the position of the mounting frame 21, so that the position of the clamp mounting plate 24 and the clamp 25 can be adjusted arbitrarily to adapt to the clamping of different types of objects. The clamp 25 can be detachably installed in the mounting groove, which is convenient for replacing the clamp 25, so as to replace the clamp 25 adapted to clamp different types of objects, thereby improving the stability of the clamping and having high applicability.
