[0024] Furthermore, the bracket 1 includes a support plate 11 and a plurality of legs 12, the roller is arranged on the support plate 11, and the plurality of legs 12 are installed at the lower part of the support plate 11. In order to improve the stability of the entire bracket 1, a connecting rod 13 is further arranged between two adjacent legs 12, so that the structure of the entire bracket 1 is more firm and reliable.

[0025] Furthermore, the driving mechanism 3 includes a motor 31, a driving shaft 32, a first driving wheel 33 and a second driving wheel 34. The motor 31 is fixed on the support plate 11, and the output shaft of the motor 31 is rotatably connected to the driving shaft 32. The driving shaft 32 is provided with a first driving wheel 33 and a second driving wheel 34. The first driving wheel 33 and the second driving wheel 34 respectively rub against the outer surface of the drum 2 and drive the drum 2 to rotate.

[0026] In order to make the drum 2 cooperate with the first driving wheel 33 and the second driving wheel 34, the cross-sections at both ends of the drum 2 are designed to be circular.

[0027] In order to ensure the stability and rotation accuracy of the driving shaft 32, a first bracket 35 is provided on one side of the first driving wheel 33, and a second bracket 36 is provided on one side of the second driving wheel 34.
