[0015] Preferably, a slot block is fixedly connected to one side of the baffle, and two grooves are provided 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 push the slot block to control the baffle to move and adjust its position.

[0017] Preferably, both sides of the baffle are fixedly connected with blocks, and one side of the control box is fixedly connected with two protruding rods.

[0018] The effect achieved by the above components is that when the baffle is pulled outward to the maximum distance, the two blocks on the outer surface of the baffle will contact the protruding rods on the outer surface of the control box, preventing the sliding rod from falling out of the inside of the slide groove.
