[0013] Furthermore, the telescopic outer cylinder is rotatably mounted on the first end of the second support shaft via a bearing, and the telescopic outer cylinder and the second support shaft are relatively fixed in the axial direction.

[0014] Furthermore, a baffle plate is fixed inside the telescopic outer cylinder, and the baffle plate limits the extreme position of the telescopic inner cylinder sliding into the telescopic outer cylinder.

[0031] The telescopic inner cylinder 4 is rotatably mounted on the first end of the first support shaft 2 via a bearing. The telescopic inner cylinder 4 and the first support shaft 2 are relatively fixed in the axial direction, so that the telescopic inner cylinder 4 can only rotate relative to the first support shaft 2 but cannot slide relatively.

[0032] A second roller assembly is provided on a side of the telescopic inner cylinder 4 and the telescopic outer cylinder 5 away from the first roller assembly.

[0033] The second roller assembly comprises a second support shaft 7 , both ends of which are provided with side brackets 3 , and a second roller 8 is rotatably mounted on the second support shaft 7 between the two side brackets 3 .

[0034] The first end of the second support shaft 7 extends beyond the side bracket 3 , and the first end of the second support shaft 7 is rotatably mounted inside the telescopic outer cylinder 5 .

[0035] The telescopic outer cylinder 5 is rotatably mounted on the first end of the second support shaft 7 via a bearing. The telescopic outer cylinder 5 and the second support shaft 7 are relatively fixed in the axial direction, so that the telescopic outer cylinder 5 can only rotate relative to the second support shaft 7 but cannot slide relative to it.

[0036] A baffle plate 6 is fixed inside the telescopic outer cylinder 5 , and the baffle plate 6 limits the extreme position of the telescopic inner cylinder 4 sliding into the telescopic outer cylinder 5 .

[0037] A bottom connecting plate 9 is provided at the bottom between the two side brackets 3 of the first drum assembly and between the two side brackets 3 of the second drum assembly. The bottom connecting plate 9 is fixedly connected to the side brackets 3 on both sides thereof.
