The movable base 81 can be movably arranged on the top of the corresponding side wall panel along the front-back direction, and the first sliding bearing seat 82 can be movably arranged on the movable base 81 along the up-down direction. The end of the first roller 2 is inserted into the first sliding bearing seat 82, and can be arranged on a pair of wall panels around the axis through the bearing in the first sliding bearing seat 82.

[0036] The movable base 81 includes a seat portion 811 that supports the first sliding bearing seat 82 and a cover portion 812 that is detachably mounted on the seat portion 811. A lifting and adjusting assembly 83 is transmission-connected between the movable base 81 and the first sliding bearing seat 82. The lifting and adjusting assembly 83 includes a lifting and lowering screw rod 831 that extends in the up-down direction and a screw nut 832 that is mounted on the cover portion 812. The lifting and lowering screw rod 831 passes through the screw nut 832, the cover portion 812 and the first sliding bearing seat 82 in sequence from top to bottom. The lifting and lowering screw rod 831 is configured to drive the first sliding bearing seat 82 to move in the up-down direction relative to the movable base 81 when rotating around its own axis, thereby realizing the adjustment of the position of the end of the first roller 2 in the up-down direction.
