[0025] The regulating mechanism 2 comprises a pipe 201, a rotating rod 202 is provided at one end of the pipe 201, the pipe 201 is movably connected to the rotating rod 202, the inner wall of the rotating rod 202 is hollow, an air port 203 is provided on the surface of one side of the top end of the pipe 201, a circular ring 204 is provided inside the rotating rod 202, lifting blocks 205 are fixedly provided at both ends of the circular ring 204, grooves 206 are provided on both sides of the inner wall of the rotating rod 202, the lifting blocks 205 are movably connected to the grooves 206, a hose 207 is provided at the bottom of the circular ring 204, an outer cover 208 is provided on one side of the bottom end of the hose 207, an exhaust fan 209 is provided inside the outer cover 208, one end of the exhaust fan 209 extends to the inside of the hose 207, a vertical rod 210 is provided on the top of the outer cover 208, and the vertical rod 210 is fixedly connected to the outer cover 208, and a sleeve 211 is provided on one side of the rotating rod 202.

[0026] The two ends of the pipe 201 are respectively connected to the air port 203 and the connection point of the rotating rod 202 , and a connecting spring is provided at the bottom of the lifting block 205 .

[0027] A threaded rod 212 is disposed at the bottom of the sleeve 211 , and the threaded rod 212 is threadedly connected to the sleeve 211 .

[0028] The bottom end of the threaded rod 212 is fixedly connected to the body 1 by means of screws. A slot 213 is provided on one side surface of the body 1 . The threaded rod 212 and the sleeve 211 are both located inside the slot 213 .

[0029] See also Figure 1-2 A steel wire rope 214 is arranged on one side of the bottom end of the threaded rod 212 , a winding rod 215 is arranged inside the bottom end of the slot 213 , the steel wire rope 214 is wound around the surface of the winding rod 215 , and torsion springs 216 are arranged at both ends of the winding rod 215 .

[0030] A fixing plate 217 is disposed at one side of the bottom end of the rotating rod 202 , and the hose 207 passes through the fixing plate 217 and contacts the fixing plate 217 .

[0031] During operation, since the pipe 201 is movably connected to the rotating rod 202, the rotating rod 202 is rotated to rotate 180 degrees, the position of the outer cover 208 at the rotating rod 202 is adjusted, and the vertical rod 210 is rotated at the same time, and then the bottom screw of the threaded rod 212 is removed, the threaded rod 212 is moved, and the top sleeve 211 is driven to move, and the wire rope 214 is stretched. When the wire rope 214 is stretched, since the wire rope 214 is wound around the winding rod 21 5, the stretching of the steel wire rope 214 causes the winding rod 215 to rotate, and causes the torsion spring 216 at the winding rod 215 to deform. When the sleeve 211 moves, the sleeve 211 can be moved to the bottom of the vertical rod 210, so that the sleeve 211 and the vertical rod 210 are aligned up and down. Then, the sleeve 211 is rotated. Since the sleeve 211 is threadedly connected with the threaded rod 212, the rotation of the threaded rod 212 causes the rotating sleeve 211 to move upward, so that the sleeve 211 and the vertical rod 210 can be merged together. After the combination is completed, the exhaust fan 209 is used first, and the external gas can enter the outer cover 208 through the exhaust fan 209, and then enter the hose 207, and then the gas is rotated through the hose 207 to the gas rotating rod 202, so that the gas is released inside the rotating rod 202. Since the two ends of the pipeline 201 are respectively connected to the gas port 203 and the connection of the rotating rod 202, the gas is passed through the pipeline 201 to enter the gas port 203 again, and then enters the inside of the body 1, and the gas is detected by the gas sensor 3 in the body 1. The threaded rod 212 can be moved, so that the sleeve 211 and the vertical rod 210 can be moved at the same time, and the outer cover 208 can be driven to move. Since the hose 207 at the outer cover 208 passes through the fixed plate 217 and contacts the fixed plate 217, the hose 207 is stretched, and the ring 204 is moved, and the lifting block 205 is moved at the same time, and the connecting spring at the lifting block 205 is squeezed, so that different height positions can be detected by moving the position of the outer cover 208, which is convenient to use.
