[0015] Preferably, a slot block is fixedly connected to one side of the baffle, and two grooves are formed on the outer surface of the slot block.

[0016] The effect achieved by the above components is that pinching the two grooves on the outer surface of the slot block can more conveniently control the slot block to push the baffle to move and adjust the position of the baffle.

[0017] Preferably, a bolt is threadedly connected to one side of the inner wall of the baffle, and a cushion block is fixedly connected to the bottom end of the bolt.

[0018] The effect achieved by the above components is that after adjusting the position of the baffle, the bolt can be rotated to move the bolt on the inner wall of the baffle so that the pad at one end of the bolt is pressed against one side of the outer surface of the box body, thereby further fixing the position of the baffle.

[0019] Preferably, the pad is made of rubber material, and the width of the pad is greater than the diameter of the bolt.
