[0013] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0014] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation to the present application.

[0015] REFERENCE Figure 1The spring pad connected with the roller comprises a bottom plate 1, a plurality of supporting springs 4 are arranged on the bottom plate 1, a guide rod 3 is arranged in each supporting spring 4, the guide rod 3 is slidably connected with the bottom plate 1 through a roller set I 2, a limiting support 12 is arranged on the guide rod 3, the upper end of the supporting spring 3 is fixedly connected with a supporting plate 5, the supporting plate 5 is fixedly connected with the guide rod 3, a supporting frame 6 is arranged above the supporting plate 5, a protective cover 9 is arranged at the top of the supporting frame 6, a drum-shaped spring 7 is arranged in the supporting frame 6, the drum-shaped spring 7 is thin at both ends and thick in the middle, the middle part is connected with a roller frame 13, the upper and lower ends of the drum-shaped spring 7 are connected with the upper and lower parts of the supporting frame 6 respectively, the guide rod 3 above the supporting plate 5 passes through the bottom of the supporting frame 6 and is connected with the upper part of the supporting frame 6 through the drum-shaped spring 7, a sliding rail 10 is arranged on each supporting leg of the supporting frame 6, two roller sets II 11 are arranged on the sliding rail 10, the roller set II 11 is fixedly connected with the roller frame 13, the drum-shaped spring 7 is connected with the roller frame 13, and the two roller frames 13 on the adjacent supporting frames 6 are connected through a connecting piece 8.
