[0028] The bottom end of the clamping seat 1 is provided with a first connecting lug 13, the other end of the first connecting lug 13 is connected with a first rotating seat 14, the side wall of the first rotating seat 14 is provided with a driving motor 15;

[0029] During operation, the driving motor 15 works to drive the first connecting lug 13 connected to the output end of the driving motor 15 to rotate, then the first connecting lug 13 rotates in the inner side of the first rotating seat 14, and the movement of the first connecting lug 13 is used to adjust the angle of the clamping seat 1.

[0030] The bottom of the first rotating seat 14 is fixedly connected with a mechanical arm 16, the other end of the mechanical arm 16 is connected with a second rotating seat 17, the side wall of the mechanical arm 16 is installed with an electric push rod 18, the bottom of the second rotating seat 17 is connected with a second connecting lug 19;

[0031] When working, the working of the electric push rod 18 pushes the mechanical arm 16 connected at one end, and then makes the mechanical arm 16 rotate around the second connecting lug 19 through the second rotating seat 17 installed at the bottom of the mechanical arm 16, so as to realize the movement of the mechanical arm 16. The two ends of the electric push rod 18 are respectively connected with the mechanical arm 16 and the auxiliary disc 20.

[0032] The bottom of the second connecting lug 19 is fixedly installed with the auxiliary disc 20, and the lower part of the auxiliary disc 20 is distributed with the counterweight base 21.

When the driving motor 15 works, the driving motor 15 works to make the first connecting lug 13 connected to the output end rotate, and then the first connecting lug 13 rotates in the inside of the first rotating seat 14, thereby adjusting the angle of the clamping seat 1 by the movement of the first connecting lug 13.

Because another independent working motor is fixedly installed in the inside of the counterweight base 21, when the motor works, the auxiliary disc 20 rotates, thereby facilitating the subsequent rotation of the mechanical arm 16, so as to adjust the direction of the clamping seat 1. At the same time, the multiple connecting plates 23 peripherally and equidistantly distributed at the bottom of the auxiliary disc 20 drive the arc-shaped block 24 to rotate, and then the arc-shaped block 24 moves along the annular groove 22, thereby improving the stability of the auxiliary disc 20 during movement.
