[0043] The outer side of the housing 2 is hinged with a clamping arm 4, and the driven member 3 can cause the driving member 22 to drive the multiple clamping arms 4 to expand or close.

[0044] The driving member 22 includes a rotating shaft 220 movably disposed in the inner cavity 21 and a cam 221 fixed to one side of the rotating shaft 220, wherein the surface of the cam 221 has abutting protrusions 222 at equal distances, and the abutting protrusions 222 and the surface of the cam 221 form a circular arc transition surface 223, wherein the gear 24 is coaxially fixed to the surface of the rotating shaft 220;

[0045] The power member 3 includes a movable groove 31 opened on the surface of the housing 2 and connected to the inner cavity 21. A tooth plate 32 is slidably arranged in the movable groove 31. The tooth plate 32 meshes with the corresponding gear 24 on one side. The tooth plate 32 can slide freely along the movable groove 31, so that the tooth plate 32 can form a meshing drive on the gear 24.

[0046] One end of the tooth plate 32 extends to the outside of the movable groove 31 and is connected to an electric telescopic rod 33. The surface of the electric telescopic rod 33 is connected to a connecting frame 34, and the connecting frame 34 is fixed to the surface of the connecting seat 1.

[0047] The clamping arm 4 includes a swinging groove 41 provided on the outer side of the housing 2, a swinging arm 42 is hinged in the swinging groove 41, a resisting rod 43 is fixed at one end of the swinging arm 42, wherein a movable cavity 44 for the resisting rod 43 to move is provided on the surface of the housing 2, one end of the resisting rod 43 extends into the inner cavity 21 through the movable cavity 44 and corresponds to the cam 221;

[0048] A clamping claw 45 is fixed to the other end of the swing arm 42. The clamping arms 4 are multiple and are evenly distributed along the circumferential direction of the housing 2.

[0049] The ends of the plurality of clamping arms 4 together form a clamping space;

[0050] A clamping platform 5 is fixed on the front of the housing 2, wherein the clamping platform 5 comprises a threaded barrel 51 fixed to the surface of the housing 2, a threaded rod 52 threadedly connected to one side of the threaded barrel 51, and a table 53 connected to one end of the threaded rod 52, wherein the table 53 is located in the clamping space;
