Then the worker can move the exhaust fan 2101 to the left to complete the disassembly of the exhaust fan 2101.

[0041] When it is necessary to disengage the exhaust device 4 from the connecting pipe 1303, the worker first rotates the fixed bolt two 2305 on the left and right sides. After the fixed bolt two 2305 on the left and right sides is disassembled, the worker can pull the handle 2304 to drive the clamping plate 2303 to move outward through the panel 2302, and the clamping plate 2303 moves outward to disengage from the sleeve frame 2301 and the connecting pipe 1303. Then the worker can move the exhaust device 4 and the connecting pipe 1303 outward to complete the disassembly of the exhaust device 4 and the connecting pipe 1303.
