Considering the walking precision and the bearing capacity of the guide rail 100 together, in an embodiment of the present invention, the guide rail 100 is a ball linear guide rail 100. In the using process, the ball linear guide 100 is not easy to deform and has a long service life.

The linear motion driving device 200 has two linear motion driving devices, the base bodies 201 of the two linear motion driving devices are respectively installed on the two guide rails 100 on both sides of the horizontal frame 500, and the movable telescopic end 202 of the linear motion driving device 200 extends out along the extension line direction of the guide rails 100. In consideration of convenience of control and cost, in an embodiment of the present invention, the linear motion driving device 200 is a telescopic cylinder.

The clamping and positioning device 300 is slidably mounted on the guide rail 100, the base 301 of the clamping and positioning device is connected to the movable telescopic end 202, and the movable clamping end 302 of the clamping and positioning device 300 extends toward the horizontal frame 500. The clamping and positioning device 300 has two parts, which are respectively slidably mounted on the guide rails 100 on both sides. Under the driving of the linear motion driving device 200, after moving to the two sides of the horizontal frame 500 along the guide rail 100, the movable clamping end 302 extends out towards the horizontal frame 500 and abuts against the two sides of the horizontal frame 500, so that the horizontal frame 500 is not easy to loosen.
