[0031] The threaded rod 213 penetrates through the connecting plate 212 and is threadedly connected to the connecting plate 212 . A limiting block 5 is provided on one side of the exhaust fan 201 , and the limiting block 5 is in contact with the exhaust fan 201 .

[0032] A connecting spring is provided at the bottom of the limiting block 5 , and the limiting block 5 is movably connected to the supporting plate 4 .

[0033] See also Figure 1-3 A cover plate 214 is arranged on the top of the moving plate 205, one end of the cover plate 214 extends to the outside of the outer cover 1 and is movably connected to the outer cover 1, the cover plate 214 is in contact with the moving plate 205, and a fixing plate 215 is arranged on the front of the outer cover 1, the fixing plate 215 is located on the top of the moving plate 205, and is fixedly connected to the moving plate 205 by screws. Through the contact between the cover plate 214 and the moving plate 205, the fan 206 can be covered, and the cover plate 214 is fixed to the fixing plate 215 by screws to prevent the cover plate 214 from moving, so as to stably protect the fan 206 and reduce the impact on the fan 206 during sandblasting.

[0034] When working, first move the whole to the position where sandblasting is required, and cover the sandblasting area with the outer cover 1. When the outer cover 1 contacts the civil air defense door, the suction cup 3 contacts the civil air defense door. The suction cup 3 can prevent the whole from moving and improve stability. The sandblasting area is covered by the outer cover 1 to prevent the gas in the outer cover 1 from leaking and polluting the environment. The threaded rod 213 is rotated, and the connection plate 212 is moved downward by the rotation of the threaded rod 213, and the downward movement of the sandblasting gun 211 is driven, so that the distance between the sandblasting gun 211 and the civil air defense door is shortened. Then, the sandblasting gun 211 is moved downward by the sandblasting gun 211. 1 performs sandblasting on the air-raid door, and uses the outer cover 1 to prevent environmental pollution, then rotates the threaded rod 213 again to move the sandblasting gun 211 upward, and moves the bottom end of the sandblasting gun 211 upward, and then moves the limiting block 5 downward, squeezes the connecting spring under the limiting block 5, and deforms the connecting spring, first removes the screws at the fixing plate 215, and moves the cover plate 214, gradually reveals the cover plate 214, opens the fan 206 below, and then uses the exhaust fan 201 and the fan 206, and moves the exhaust fan 201, and drives the pipe 20 2 moves, and the delivery pipe 203 and the push plate 204 move at the same time. When the delivery pipe 203 moves, different positions of the housing can be dusted to reduce dust. When the push plate 204 moves, the fan 206 below moves at the same time. By moving the push plate 204, since the push plate 204 contacts the outer cover 1, the gas can be pushed, and the dust can be easily absorbed through the delivery pipe 203. The fan 206 is located inside the bottom end of the outer cover 1 and can blow the dust inside the bottom end of the outer cover 1, so that the dust can easily enter the delivery pipe 203, and the dust can be fully cleaned. The dust is absorbed and moves into the release tube 207. Since the release tube 207 passes through the folded plastic tube 210 and the flow tube 209, the dust enters the folded plastic tube 210 and the flow tube 209, and is released through the flow tube 209 and released into the gas in the water tank 208. The dust can come into contact with the gas, thereby reducing the dust in the gas and preventing environmental pollution during subsequent discharge. When the exhaust fan 201 moves, the release tube 207 will move at the same time, and the folded plastic tube 210 will be stretched, causing the folded plastic tube 210 to deform, thereby ensuring the movement of the exhaust fan 201.
