The first buckle pawl 309 is also used to disengage from the connection frame 301 when being pulled and drive the dust filter 302 to slide out of the first limited space 311 through the first sliding hole 307;

[0050] A second claw 310 is installed on the outer wall of the moisture-proof membrane 304, and the second claw 310 can be slidably inserted into the second sliding hole 308. The second claw 310 is used to drive the moisture-proof membrane 304 to slide into the second limiting space 312 through the second sliding hole 308 when being pushed, and the second claw 310 is used to engage with the connecting frame 301 when the moisture-proof membrane 304 slides into the second limiting space 312. The second claw 310 is also used to disengage from the connecting frame 301 when being pulled and drive the moisture-proof membrane 304 to slide out of the second limiting space 312 through the second sliding hole 308.
