54, rubber cup 51 is connect with the one end fits of pressure scale pipe 52, and pressure scale pipe 52 is set in one end of compression spring 53
Outside, and the length of pressure scale pipe 52 is less than the length of compression spring 53, the bullet of the other end and locking cap 54 of compression spring 53
Spring mounting post connects, and locking cap 54 is fixed with 2 back-end sealing of handle.Gas passes through the first gas channel 22 into and out first
Accommodating cavity 24 drives rubber cup 51 and pressure scale pipe 52 to be moved in the first accommodating cavity 24.2 outer wall of handle is additionally provided with use
In the transparency display window 25 of display 52 high scale value of pressure scale pipe.
Pneumatic adjusting mechanism 6 includes gas bleeder valve 61 and ball sealer 62, and the material of ball sealer 62 is rubber in the present embodiment.The
The exit of two gas channels 23 is provided with the airway open portion 26 that bore from the inside to the outside is sequentially increased, and gas bleeder valve 61 is moveable
It is arranged in handle 2 and positioned at the top in airway open portion 26, ball sealer 62 is arranged in airway open portion 26, ball sealer 62
Diameter is more than the caliber of the second gas channel 23, and the bottom of gas bleeder valve 61 is provided with the groove 63 being embedded in for ball sealer 62.It beats
61 crush seal ball 62 of gas bleeder valve closes the second gas channel 23 when gaseity;The Forward of gas bleeder valve 61 makes ball sealer when air deflating state
62 insertion grooves 63, are respectively formed between ball sealer 62 and handle 2, between gas bleeder valve 61 and handle 2 and connect with the second gas channel 23
Logical outlet gap.
Gas bleeder valve 61 includes discouraged valve body 611, is arranged and is losing heart in the draw runner 614 for 611 both sides of valve body of losing heart, setting
The fixture block 613 and operation convex block 612 of 611 top of valve body.It is arranged in parallel with and the along 1 direction of pressurized cylinder component in handle 2
Two gas channels 23 are connected the second accommodating cavity 27, and the valve body 611 that loses heart is arranged in the second accommodating cavity 27, and the setting of groove 63 exists
The bottom of discouraged valve body 611, for being embedded in for ball sealer 62, the surface of groove 63 is preferably the surface shape with ball sealer 62
The arc surface to fit.The two side of second accommodating cavity 27 is provided with sliding slot 271, and draw runner 614 is embedded in sliding slot 271, draw runner 614
