The driving member 27 drives the slider 26 to slide along the length direction of the support rod 25 to drive the supporting plate 22 to rise and fall and adjust its height.

[0027] Specifically, the support rods 25 are symmetrically arranged at the two ends of the fixed plate 21. The two support rods 25 are sleeved and slidably fitted with sliders 26. The two sliders 26 are respectively fixedly connected to the two ends of the supporting plate 22. The driving member 27 is an electric telescopic rod, and there are also two symmetrical ones.
