When it moves to 41 When the pressure on the lower pressure plate 9 is released, the block 11 is driven to enter the body 41 under the reset of the spring 10, and the block 11 is limited. In this way, the middle plate 7 and the drive shell 121 can be limited from being separated from the self-assembly groove 2 without the action of external force, thereby ensuring the overall stability. Similarly, after pressing the lower pressure plate 9 to separate the block 11 from 41, the middle plate 7 is rotated to allow the block 11 to rotate to the through opening. At this time, the limit platform 8 can be pulled to separate the middle plate 7 and the drive shell 121 from the self-assembly groove 2. At this time, other components are reset for easy disassembly.
