Transmission grooves 9 are arranged at the top and bottom of each installation groove 8 in the smoke exhaust valve body 2. Slide plates 12 are slidably connected in the two transmission grooves 9. Pin rods 15 are fixedly installed on the sides of the two slide plates 12 away from each other. Pin grooves 14 are arranged at the corresponding positions of the plurality of pin rods 15 in the smoke exhaust pipe 1. The sides of the plurality of pin rods 15 away from the slide plates 12 extend into the corresponding pin grooves 14 respectively. Steel wire ropes 10 are fixedly installed on the sides of the plurality of slide plates 12 close to the installation grooves 8. Two handles 3 are arranged at the front end of the smoke exhaust valve body 2. The sides of the plurality of steel wire ropes 10 away from the slide plates 12 are fixedly installed on the corresponding handles 3 respectively. Springs 13 are sleeved on the outer sides of the plurality of steel wire ropes 10.

[0021] One side of the plurality of springs 13 is fixedly mounted on the slide plate 12, and the side of the plurality of springs 13 away from the slide plate 12 is fixedly mounted on the inner wall of the transmission groove 9. This design is conducive to the use of the device.
