[0024] The working principle of the utility model is:

[0025] In the process of installing the smoke exhaust device, first of all, the smoke exhaust pipe 7 needs to be inserted into the auxiliary plate 3 on one side of the exhaust fan 6, which provides preliminary positioning and support for the subsequent installation work. Then, the installer starts the driving motor 101 located above the auxiliary plate 3 and drives the adjusting screw 102 connected to the output end of the driving motor 101 to rotate through the belt transmission. The threads on both ends of the adjusting screw 102 are in opposite directions, which means that when the screw rotates, the two connecting blocks 103 on it will move in opposite directions. The two connecting blocks 103 are connected to the sealing plate 104 below. With the movement of the connecting blocks 103, the sealing plate 104 will also slide on the auxiliary plate 3 until it tightly contacts the surface of the smoke exhaust pipe 7, finally achieving effective fixation of the smoke exhaust pipe 7. In order to ensure stability during the whole process, a slide rod 105 is added at the bottom of the sealing plate 104, which not only helps the smooth movement of the sealing plate 104, but also ensures the straightness during movement. In addition, when the sealing plate 104 advances forward, the positioning plate 203 on the fixed block 201 will automatically embed into the cooperating block 202. Once installed in place, the limiting blocks 205 on both sides of the positioning plate 203 will be pushed out outward under the joint action of the telescopic rod 206 and the spring 207, sliding along the surface of the cooperating block 202, further enhancing the fixing effect and ensuring the stability of the installation structure. When it is necessary to disassemble or maintain the smoke exhaust pipe 7, the user only needs to gently pinch the two limiting blocks 205 on the cooperating block 202, causing the limiting blocks 205 to retract into the fixed block 201, and then reverse the driving motor 101. At this time, the two sealing plates 104 that were tightly attached to the smoke exhaust pipe 7 will simultaneously retreat to both sides, thereby releasing the pressure on the smoke exhaust pipe 7, so that the smoke exhaust pipe 7 can be easily pulled out of the auxiliary plate 3.
