As shown in the attached drawings Figure 1 it includes two vertically extending guide rails 100, on each of the two guide rails 100 there is slidably provided a slider 200, and the two sliders 200 are connected to a height adjustment drive assembly 300 that drives them to move synchronously up and down along the guide rails 100, and there is only one drive source 310 located outside one of the guide rails 100 in the height adjustment drive assembly 300.

[0030] As shown in the attached drawings Figure 1 and in the attached drawings Figure 2As shown, the upper ends of the two guide rails 100 are connected by an upper cross beam 400, and the lower ends of the two guide rails 100 are connected by a lower cross beam 500, thereby forming a rectangular frame. Notch openings are formed on the sides of the two guide rails 100. The slider 200 includes a first member 210 and a second member 220.

The horizontal mounting plate 223 is located at the lower end of the second vertical plate 222. The two horizontal mounting plates 223 are used to mount a conveyor, and the two horizontal mounting plates 223 are located at the middle positions on the sides of the conveyor.

[0031] The structure of the height adjustment driving assembly 300 can adopt different structures. In one embodiment, as shown in the appendix Figure 2 As shown, the height adjustment driving assembly 300 includes synchronous pulleys 320 provided on mounting seats 310 at the upper and lower ends of the two guide rails 100. The axle 321 of each synchronous pulley 320 is rotatably provided on the mounting seat 310 through a bearing. A driving belt 330 is sleeved on the two synchronous pulleys 320 at the upper and lower ends of each guide rail 100. The driving belt 330 is connected to one of the sliders 200. The two coaxial synchronous pulleys 320 are torsionally connected through a transmission shaft 340. One of the synchronous pulleys 320 is connected to a driving source 310 that drives its rotation. The driving belt 330 is threaded through the inner cavity of the guide rail 100.
