[0023] The screw seat 402 is symmetrically welded with both sides of the aerosol fire extinguisher 1, the screw 403 is connected to the screw seat 402 by threads, the suction cup 401 is rotatably connected to one end of the screw 403, and the screw 403 is rotated to drive the suction cup 401 to move under the action of the screw seat 402, and then the device is pre-fixed by the suction cup 401.

[0024] The driving hole 407 is formed on the screw rod 403 , and the specification of the driving rod 404 matches the specification of the driving hole 407 . The driving rod 404 can rotate the screw rod 403 through the driving hole 407 .

[0025] The fixed part of the telescopic column 409 is connected to the aerosol fire extinguisher 1 by screws, and the movable end of the telescopic column 409 is connected to the transmission box 405 by bolts. The telescopic column 409 is combined with the spring 408 to enable the transmission box 405 to have a certain mobility.

[0026] The driving wheel 412 and the driven wheel 411 are both rotatably connected to the transmission box 405, and the driving wheel 412 and the driven wheel 411 are connected by a belt 410. The knob 406 passes through the transmission box 405 and is welded to the driving wheel 412. One end of the driving rod 404 is connected to the driving wheel 412 and the driven wheel 411 by screws. The knob 406 drives the driving wheel 412 to rotate, and the driving wheel 412 drives the driven wheel 411 to rotate through the belt 410.
