Portion's air pressure, push rod 200 can be extruded so that operation can not be carried out.Now, switching brake bar 350 counterclockwise pulls handle
354 so that the first end of brake bar 350 slides onto braking position of the inclined-plane of contiguous block 330 away from the tubular pump housing 100, so as to
Contiguous block 330 will be braked and push up shifting, and compression spring 340a, 340b towards the direction of push rod 200, braking contiguous block 330 promotes system
Braking screw thread 321 on motion block 320 engages with the external screw thread 210 on push rod 200, so as to which anti-throw-out lever 200 is extruded, now,
Accurately pressurization and pressure release can be realized by the turn handle 230 of turn push rod 200.When needing complete pressure release, clockwise
Switching brake bar 350 pulls handle 354 so that the inclined-plane that the first end of brake bar 350 slides onto braking contiguous block 330 is close
The position of the tubular pump housing 100, under spring 340a, 340b elastic-restoring force effect, braking contiguous block 330 is directed away from push rod
200 direction is jacked up so that the braking screw thread 321 on brake block 320 is disengaged from shape with the external screw thread 210 on push rod 200
State, now can free push-and-pull push-and-pull push rod 200 in the tubular pump housing 100.
