The operation is simple and convenient for the staff to use. At the same time, when the second lever 3105 is pulled, the rectangular card rod 3203 is automatically connected to the right in the pull rod 3104 under the action of the compression spring three 3204 to position the pull rod 3104.

When it is necessary to disassemble the sound insulation board 3304, the staff first pushes the lever 3205 to move to the left. The lever 3205 moves to the left and drives the rectangular clamping rod 3203 to move to the left through the slide cylinder 3202 on the upper and lower sides. The rectangular clamping rod 3203 moves to the left and retracts into the fixed cylinder 2 3201 to release the positioning of the pull rod 3104. Then the staff pulls the lever 2 3105 forward again. The lever 2 3105 moves forward and drives the clamping plate 3103 to move forward and retract into the main shell 4 through the pull rod 3104 and the compression spring 2 3102. At this time, the clamping plate 3103 is disconnected from the mounting block 2301. Then the staff releases the positioning of the lever 3205 again. At this time, the slide cylinder 3202 drives the rectangular clamping rod 3203 to move to the right by itself under the action of the compression spring 3204. The rectangular clamping rod 3203 moves to the right and is clamped in the pull rod 3104 to complete the positioning of the pull rod 3104. Then the staff can flip the closing door 2203 outward to complete the opening and closing of the closing door 2203, and then the staff can move the positioning frame 2303 to the left or right to separate the positioning frame 2303 from the connection with the partition 2 1102, and complete the disassembly of the positioning frame 2303. Then the staff can push the lever 1 2505 downward, and the lever 1 2505 moves downward through the slide 1 2502 to drive the protruding rod 2504 to move downward, and the protruding rod 2504 moves downward and retracts to the fixed position. The connection between the fixed cylinder 2501 and the sleeve ring 2506 is released, and then the staff can pull the handle 2405 to the left to drive the positioning rod 2404 to move to the left.
