[0029] Among them, Figure 3 As shown, the rotating shaft 4 forms a rotating structure through the motor 2 and the gear 5, which is conducive to driving the gear 5 to rotate through the rotating shaft 4, providing power for the rack 6 to slide, and achieving the effect of opposite movement.

[0030] Among them, Figure 3 As shown, the gear 5 fits tightly with the rack 6 , and the gear 5 forms a meshing structure with the rack 6 through the rotating shaft 4 , which is conducive to driving the rack 6 to rotate through the gear 5 , pulling the sliding bar 7 to slide, and adjusting the position of the suction cup 11 .

[0031] Among them, Figure 2 As shown, the bottom plate 3 is provided with a sliding groove that matches the rack 6. The rack 6 forms a sliding structure with the bottom plate 3 through the gear 5, which helps to prevent the rack 6 from being unstable and sliding out when moving.

[0032] Example 2

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, a connecting column 12 is provided on the top of the supporting leg 1, a spring 13 is fixedly connected to the bottom of the connecting column 12, a limiting column 14 is fixedly connected to the bottom end of the connecting column 12, a barrel block 15 is fixedly connected to the bottom end of the spring 13, a fixed block 16 is fixedly connected to the outer wall of the bottom plate 3, a telescopic column 17 is fixedly connected to the top of the fixed block 16, and a connecting plate 18 is fixedly connected to the top of the telescopic column 17.
