A support plate 13 is arranged at the bottom of the sleeve 12, and the support plate 13 plays a supporting role for the device body 1.

[0037] See also Figure 1-Figure 4 In the above embodiment, four rotating plates 2 are provided, and the four rotating plates 2 are all rotatably connected with the device body 1. The rotation of the worm gear 7 drives the rotating shaft 3 to rotate, and the rotation of the rotating shaft 3 drives the rotating plate 2 to rotate. The rotation of the rotating plate 2 drives the roller 6 to rotate. The roller 6 is rotatably connected with the device body 1 through the rotating plate 2, the damper 4 and the spring telescopic rod 5.
