[0022] Working principle:
[0023] Firstly, the pneumatic power module 2 is provided, which is composed of an input air pipe 21, an output air pipe 23, and an air valve 22. The input air pipe 21 is in communication with an external air source, and the air valve 22 controls whether the output air pipe 23 injects gas into the air cylinder 31.
[0024] When the air valve 22 is opened, gas is injected into the air cylinder 31 through the output air pipe 23. The air cylinder 31 drives the driving gear 32 to rotate, and the driven gear 33 is engaged on both sides of the driving gear 32 and rotates synchronously with the driving gear 32.
[0025] The driven gear 33 is arranged on the top surface of the ball valve 42 and is in power connection with the ball valve 42.
