[0071] As shown in Figure 5As shown, optionally, the first support member 81 includes two first support arms 811, and the second support member 82 includes two second support arms 812, and the two first support arms 811 are located between the two second support arms 812, thereby realizing a cross connection between the first support member 81 and the second support member 82, and also avoiding interference between the first support member 81 and the second support member 82 during the sliding process; the support base 83 is provided with a plurality of through areas, and the number of the through areas corresponds to the number of support assemblies; the length of the through area is greater than the length of the first support arm 811 and the second support arm 812, so that when the lifting mechanism 8 is in the descending state, the first support member 81 and the second support member 82 can be completely in the through area, avoiding interference of the support base 83 with the first support member 81 and the second support member 82, and also avoiding the first support member 81 and the second support member 82 protruding from the support base 83, so that the height occupied by the lifting mechanism 8 in the descending state is equal to the thickness of the support base 83, which can reduce the space occupied by the lifting mechanism 8 in the descending state, further improve space utilization, and avoid affecting the layout of other modules.

[0072] like Figure 5 As shown, the support base 83 includes a plurality of connecting beams 831, which are arranged parallel to each other and extend along the length direction of the support base 83. Two adjacent connecting beams 831 are respectively provided with first grooves 8311 with openings facing each other. A roller 84 is provided at one end of the second support arm 812. The roller 84 can slide along the first groove 8311, so that the second support member 82 can slide relative to the support base 83, and the height of the support platform 6 is also adjusted.
