[0027] The pushing piston block 403 is a cylindrical block structure. The pushing piston block 403 is installed inside the first chamber. The outer periphery of the pushing piston block 403 is sealed and fitted with the inner periphery of the first chamber, and can perform piston motion. The center line of the pushing piston block 403 extends vertically.

[0028] The sliding sleeve ring 401 is a circular ring structure. The sliding sleeve ring 401 is sleeved on the outer periphery of the first chamber and can slide along the axial direction of the first chamber. The center line of the sliding sleeve ring 401 extends vertically.

[0029] The push connecting frame 402 is a U-shaped rod-shaped structure. The push connecting frame 402 is fixedly connected to the two sides of the outer periphery of the sliding sleeve ring 401 and the center of the push piston block 403, so that when the sliding sleeve ring 401 slides on the handheld air pressure cylinder 1, the push connecting frame 402 can drive the push piston block 403 to slide in the handheld air pressure cylinder 1. The opening of the push connecting frame 402 is downward.

[0030] The reset jacking spring 15 is supported between the push piston block 403 and the fixed connecting plate 2, and connects the push piston block 403 and the fixed connecting plate 2, and can automatically reset the push piston block 403 under the action of the automatic restoring force of the reset jacking spring 15.

The second grip 6 is used to push the piston block 403 to perform piston movement. By holding the second grip 6, the sliding sleeve ring 401 can slide on the handheld air cylinder 1. The second grip 6 is arranged horizontally.

[0032] Through the above arrangement, when in use, the second grip 6 is gripped to drive the gas extrusion assembly 4 to slide on the handheld air cylinder 1, thereby compressing the gas in the handheld air cylinder 1, and allowing the gas to flow through the connecting air holes opened on the fixed connecting plate 2.

[0042] Through the above arrangement, when in use, the compressed gas generated by the gas extrusion component 4 enters the connecting gas cylinder 7. Under the action of the one-way valve 8, the gas is prevented from flowing back into the handheld air cylinder 1, so that the air pressure in the connecting gas cylinder 7 gradually increases. The air pressure data in the connecting gas cylinder 7 is transmitted to the display 11 through the pressure sensor 9. The display 11 is observed, and the gas extrusion component 4 is controlled to make the air pressure in the connecting gas cylinder 7 at the required value.
