The second sliding rods 710 are fixedly connected to the side of the second support plate 300 facing the first support plate 200, and the second sliding sleeves 720 are fixedly connected to the first support plate 200.

[0025] In the embodiment of the present utility model, through the first sliding mechanism 600 and the second sliding mechanism 700, the sliding connection between the second support plate 300 and the first support plate 200 is realized. The first sliding rod 610 and the second sliding rod 710 are both arranged in the vertical direction. The first sliding rod 610 passes through the first sliding sleeve 620, and the second sliding rod 710 passes through the second sliding sleeve 720, ensuring the stability of the movement of the second support plate 300 relative to the first support plate 200 in the vertical direction.
