When the slide bar (25) slides to the second chute of the chute plate (21), it reciprocates, so that the cleaning block (26) can reciprocate left and right. Step 3: When the slide bar (25) is in the first slide groove at the bottom of the slide groove plate (21), the box cover (36) is in a closed state. When the slide bar (25) is separated from the first slide groove at the bottom of the slide groove plate (21), the moving block (23) drives the slide bar (25) to move to the left, the slide bar (25) drives the moving block (23) to move to the left, the moving block (23) drives the first hydraulic chamber (31) to move to the left, the first hydraulic chamber (31) drives the first hydraulic rod (32) and the gasket (33) to move closer to the inner wall of the frame (1), when the first hydraulic rod (32) slides into the first hydraulic chamber (31), the second spring (34) is squeezed, and during the movement of the first hydraulic rod (32), the internal pressure of the first hydraulic chamber (31), the connecting hose (39) and the second hydraulic chamber (37) increases, driving the second hydraulic rod (38) to rise, and the rising of the second hydraulic rod (38) drives the box cover (36) to rise; Step 4: When the blackboard (7) descends, the trigger rod (46) is driven to descend, and the descending of the trigger rod (46) drives the card plate (42) to descend, and the card plate (42) descends to squeeze the third spring (43). When the bottom of the card plate (42) is completely tilted up, the tool box (45) is no longer limited, and the fourth spring (44) drives the tool box (45) to pop out.
