Fig. 6 is referred to, push rod 14 is provided with the first inclined-plane 143 away from one end end face of handle 141.13 are handled away from pushing hands portion
The medial wall of 132 one end is provided with boss 135.Boss 135 is provided with the second inclined-plane 136, the first inclined-plane 143 and the second inclined-plane 136
Abut against.Also, the first inclined-plane 143 and the following table that the angle of the upper surface of push rod 14 is acute angle, the first inclined-plane 143 and push rod 14
The angle in face is obtuse angle.Corresponding, the second inclined-plane 136 is parallel to each other with the first inclined-plane 143.Then when push rod 14 with handle 13 phases
To when motion, because push rod 14 is contacted by the first inclined-plane 143 with handling 13 with the second inclined-plane 136, the first inclined-plane 143 and
The relatively oblique motion in second inclined-plane 136.That is, when elastic component 18 recover elastic deformation, push rod 14 with handle 13 be relatively distant from when
Wait, push rod 14 is moved obliquely along the second inclined-plane 136, then the position of push rod 14 raises.Push rod 14 is raised, and drives the position of screw rod 15
Put and also increase, it is ensured that the external screw thread 153 of screw rod 15 can be engaged with the female thread 115 of spiral head 114.In the same manner, compression is worked as
Elastic component 18, make push rod 14 with handle 13 it is relatively close when, push rod 14 is moved obliquely along the second inclined-plane 136, then push rod
14 position reduces.Push rod 14 is reduced, and the position for driving screw rod 15 also decreases, it is ensured that the external screw thread 153 of screw rod 15 can
Depart from the female thread 115 of spiral head 114.
Equally, the 3rd inclined-plane 155, the 3rd inclined-plane 155 and second are provided with away from one end end face in pushing hands portion 132 in screw rod 15
Inclined-plane 136 is abutted against.3rd inclined-plane 155 is parallel with the first inclined-plane 143, then screw rod 15 can also be along the oblique fortune in the second inclined-plane 136
It is dynamic, screw rod 15 is smoothly lifted.
Concrete in the present embodiment boss 135 is two, and two boss 135 are oppositely arranged two with the first inclined-plane 143
Side.Second inclined-plane 136 of two boss 135 is abutted against respectively with the both sides on the first inclined-plane 143, make push rod 14 and boss 135 it
Between stress balance, it is ensured that push rod 14 can be moved smoothly along the second inclined-plane 136.
Fig. 1 is referred to, in above-mentioned compression pump 10, the handle 141 of push rod 14 is held by handss and is handled 13 pushing hands portion
132, push rod 14 is subject to power backward to move axially rearward, and handle 141 is close to each other with pushing hands portion 132, presses elastic component 18
Contracting.The groove 152 that projection 142 on push rod 14 is entered on screw rod 15, while connecting rod 16 swings to the left, screw rod 15 falls to inside contracting,
And depart from the female thread 115 of spiral head 114, then handss are enforced and realize that handling 13 significantly moves, and enters to the pump housing 11
Row pressurising.When correct position is reached, handss unclamp.Fig. 5 is referred to, the effect of the elastic-restoring force of elastic component 18 makes handle 141
It is located remotely from each other with pushing hands portion 132, the projection 142 of push rod 14 departs from the groove 152 of screw rod 15, makes screw rod 15 move right, even
Bar 16 swings to the right, and screw rod 15 rises, and is meshed with the female thread 115 of cavity 111.Rotary handle 13, screw rod 15 and the pump housing
