[0009] Furthermore, the left side of the water flow pipe passes through the connecting sleeve, the left side of the connecting sleeve is fixedly connected with a connecting pipe, and the inner wall of the water flow pipe is provided with a groove.

[0010] Furthermore, the moving mechanism includes a main body fixedly connected to the right side of the fixed sleeve, a push rod is fixedly connected to the right side of the main body, a storage tank is fixedly connected to the inner wall of the main body, and a pressure gauge is fixedly connected to the top of the storage tank.

[0011] Furthermore, the top of the pressure gauge penetrates the main body and extends to the outside, an air outlet pipe is fixedly connected to the left side of the storage tank, an electromagnetic valve is fixedly connected to the outer surface of the air outlet pipe, and the left side of the air outlet pipe penetrates the main body and extends to the outside.

[0012] Furthermore, the left side of the air outlet pipe is fixedly connected to the right side of the fixed sleeve, the left side of the bottom of the storage tank is fixedly connected to the air inlet pipe, the top of the air inlet pipe is fixedly connected to a connecting column, and the connecting column is rotatably connected to a rotating shaft.

[0013] Furthermore, a sealing plate is fixedly connected to the outer surface of the rotating shaft, a spring three is fixedly connected to the top of the sealing plate, the other end of the spring three is fixedly connected to the inner wall of the connecting column, a pressure relief valve is fixedly connected to the top of the connecting column, and a sealing ball three is slidably connected inside the pressure relief valve.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model sets a water flow pipe, connects the connecting sleeve to the fixed sleeve, and then rotates the fixed ring to make the connecting sleeve move to the right. When the connecting sleeve moves to the right, it will drive the sealing ball 2 to push the water flow pipe to the right, and at the same time, the sealing ball 1 is pushed to the right through the water flow pipe. After the water flow pipe moves to the right to a certain distance, it will be stuck by the inner wall of the fixed sleeve, so that the sealing ball 2 is separated from the inner wall of the connecting sleeve, ensuring that the gas can pass normally. At the same time, the middle of the connecting sleeve and the fixed sleeve is sealed through the water flow pipe to reduce gas leakage and enhance sealing.

[0017] 2. The utility model sets a sealing plate. When the air pressure is too high, the sealing plate will be lifted up and the spring three will be squeezed. Then, the sealing plate will be lifted up through the connecting column into the pressure relief valve to cancel the seal, so that the excess air pressure is discharged through the air pressure groove. When the air pressure is stable, the spring three will rebound to push the sealing plate downward to reseal, thereby preventing danger caused by excessive air pressure.
