To bar (21), to which guide rod (21) be stablized in cavity (15) and play guiding role simultaneously；
The tail end of device (2) is connected to support by a first bolt axis pin (7) during cavity (15) tail end is returned as spring
On plate (1), the front end of device (2) passes through another the first bolt axis pin during guide rod (21) tail end is returned as spring
(7) it is coupled with balancing pole (6) top.
7. conjuncted hydraulic pump motor automatic cycle as claimed in claim 6 tests Pneumatic operating mechanism, which is characterized in that described
The internal diameter design more corresponding than cavity (15) of the maximum gauge of spring base (17) is smaller, and spring base (17) is in cavity (15) when movement
There are guiding roles；
The diameter of the guide rod (21) internal diameter more corresponding than guide cover (20) and spring base (17) designs smaller, guide rod (21)
There are guiding roles when movement in guide cover (20) and spring base (17).
8. conjuncted hydraulic pump motor automatic cycle as claimed in claim 6 tests Pneumatic operating mechanism, which is characterized in that in handle
After spring base (17) and spring (18) are arranged guide rod (21), by being tightened from screw-making (16)；Wherein, from screw-making (16)
It is set as：Screw area of bed is more than standard screws, and is not outer six side of standard, for the structure that two sided planar can fasten, plays
The effect of push the spring seat (17) and guide rod (21) simultaneously.
9. conjuncted hydraulic pump motor automatic cycle as described in claim 1 tests Pneumatic operating mechanism, which is characterized in that described
Connecting joint (3) and balancing pole (6) are coupled by axis pin (4) with split pin (5).
10. conjuncted hydraulic pump motor automatic cycle as described in claim 1 tests Pneumatic operating mechanism, which is characterized in that institute
The balancing pole (6) of use arranges that cylinder (14), spring return middle device (2) according to distance proportion；Connecting joint (3) is access manually
Point, rotary joint (12) are pneumatic access point, are set as to realize manual function and pneumatic function respectively, according to balancing pole (6)
Access point distance proportion rationally designs the active force of device (2) during cylinder (14) is returned with spring.
