[0022] The working principle of this embodiment is as follows:

[0023] When the dust cover 15 needs to be disassembled, the screw rod 12 is rotated. At this time, the threaded strip on the outside of the screw rod 12 contacts the threaded groove on the inner wall of the screw block 13. The position of the screw block 13 is limited by setting a slider, which drives the screw block 13 to move to the right, thereby driving the dust cover 15 to move to the right. At this time, the dust cover 15 will no longer fit tightly with the flange body 3. Subsequently, the dust cover 13 can be pulled downward to release the plug-in relationship between the dust cover and the plug-in frame 14, so that it can be effectively disassembled and cleaned.
