[0020] Furthermore, the upper surface of the fixing frame 9 is fixedly connected to the driving motor 6, the output shaft of the driving motor 6 is fixedly connected to the gear 10, and the outer surface of the upper end of the round rod 12 is fixedly sleeved with a gear ring 11, and the gear 10 is meshed with the gear ring 11.

[0021] Furthermore, the lifting mechanism includes a screw rod 3 rotatably installed inside the vertical slot 2, a lifting motor 4 is fixedly installed on the top of the workbench 1, the output shaft of the lifting motor 4 is fixedly connected to the screw rod 3, a ball seat 5 is provided on the surface of the screw rod 3, and the ball seat 5 is fixedly connected to the lifting plate 7.

[0022] In this embodiment, the ball screw is an existing transmission element, and its main function is to convert rotational motion into linear motion. It will not be repeated here. During actual use, it is necessary to connect the lifting motor 4 to an external power supply and drive the lifting motor 4 forward and reverse to make the ball seat 5 move up and down along the screw rod 3.

[0023] Furthermore, there are at least three groups of clamping mechanisms, and the three groups of clamping mechanisms are distributed in a circular array with the through hole 19 as the axis. The clamping mechanisms all include an electric push rod 17, which is radially arranged along the through hole 19.
