[0026] Two groups of rotating columns 203 are rotatably installed in the mounting seat 201, and sliding grooves are opened on the rotating columns 203. The two groups of rotating columns 203 are symmetrically arranged and correspondingly arranged above the supporting column 1. The outer walls of the two groups of rotating columns 203 are symmetrically slidably installed with two groups of sliding rings 204, and the outer walls of the sliding rings 204 are in contact with the upper surface of the supporting column 1.

[0027] By installing two sets of rotating columns 203 in the mounting base 201, the sliding ring 204 installed on the rotating column 203 slides on the support column 1 to drive the mounting base 201 to move to different positions. Through the sliding groove on the rotating column 203, the sliding ring 204 can make corresponding adjustments to the support columns 1 of different widths.

[0028] One end of the output shaft of the driving motor 202 passes through one side of the mounting seat 201 and is fixedly connected to one end of a set of rotating columns 203.
