Face directly axially vertical with clutch-plate 113, the screw thread of clutch-plate 113 is faced directly to be formed with facing directly for the screw thread of threaded rod 116
Mutually to the form pushed up, inclined-plane is mutually abutted, so as to limit the trend of the movement axially rearward of clutch-plate 113.Similarly
, it is connected together due to clutch-plate 113 and handle 121, therefore the trend of the movement axially rearward of handle 121 is also subject to
Limitation.The last mobile trend axially rearward of piston head 127 is also restricted, so as to ensure what compression pump 10 can be stablized
Supercharging and pressurize.
Elastic component 132 is connected between the second curved boom 134 and handle portion 124, and elastic recovery is acted on to the second curved boom 134
Power.Elastic component 132 is compression spring, and handle portion 124 is provided with locating dowel 1242, and compression spring is sheathed in locating dowel 1242.It is fixed
Position post 1242 can prevent elastic component 132 in telescopic process with spacing elastic component 132, be moved, and influence compression pump 10 makes
With.
It is appreciated that elastic component 132 can also be spiral compression spring, extension spring, torsional spring etc..
When external force is applied to clutch-plate 131, the extruding elastic component 132 of the second curved boom 134 applies one to elastic component 132
Pressure, clutch-plate 131 139 is rotated around the shaft, according to lever principle, the first curved boom 133 is departed from threaded rod 113.Now may be used
With free driving handle 121, enable the greatly motion in cavity 111 of push rod 122.When push rod 122 reaches suitable position
When putting, when active force is removed, due to the elastic restoring force of elastic component 132, clutch-plate 131 is rotated backward, made
First curved boom 133 is engaged with threaded rod 113.Clutch-plate 131 makes under the impetus of the elastic restoring force of elastic component 132
One curved boom 133 keeps engaging with threaded rod 113.
Fig. 6, also, the handle 121 that turns clockwise are referred to, handle 121 drives clutch-plate 131 to be revolved with handle 121
Turn, then make the screw thread rotation of the threadingly bar 113 of clutch-plate 131, make the axial advancement of the threadingly bar 113 of push rod 122, equivalent to pressure
Power pump 10 carries out supercharging work.Also, the top of the first curved boom 133 is limited in the stopper slot 126 of reinforcing ring 125.Work as handle
121 relative to threaded rod 113 when rotate, and clutch-plate 131 is stably rotated with handle 121, prevents clutch
Piece 131 is shifted over.
Fig. 7 is referred to, in release, taking out the negative pressure course of work, one hand holds handle 121 and clutch-plate 131, makes clutch-plate
131 pairs of elastic components 132 apply an active force, and elastic component 132 is compressed, and clutch-plate 131 is rotated along rotating shaft 139.Refer to figure
8, the first curved boom 133 of clutch-plate 131 is separated with threaded rod 113, now injecting mechanism 12 can sliding axially along the pump housing 11, return
Remove injecting mechanism 12, you can complete the release of compression pump 10, take out negative pressure work.
In above-mentioned compression pump 10, injected by being threaded bar 113 on the pump housing 11, and clutch 13 being incorporated into
In mechanism 12.When not applied by external force, clutch-plate 131 receives the screen resilience of elastic component 132 to second curved boom 134 of clutch-plate 131
The first curved boom 133 is promoted to be engaged with the threaded rod 113 of the pump housing 11.Now rotate the handle 121 of injecting mechanism 12, the band of handle 121
The dynamic rotating Vortex of clutch-plate 131, clutch-plate 131 is advanced along the hand of spiral of the threaded rod 113 of the pump housing 11, drives injecting mechanism 12
Moved towards the distal end of the pump housing 11 along the axis direction of the pump housing 11, supercharging work is carried out equivalent to compression pump 10.
Therefore, above-mentioned compression pump 10 in release, the course of work for taking out negative pressure, can be used single relative to conventional pressure pump
Hand is operated, and improves convenience.Also, the clutch-plate 131 of above-mentioned compression pump 10 is larger with the area of contact of threaded rod 113, it is ensured that
The pressure stability of compression pump 10 in supercharging.
It is appreciated that the shape of clutch-plate 131 can be with other shapes, as long as ensureing the first curved boom 133 and the second curved boom 134
Between there is certain angle, the first curved boom 133 of clutch-plate 131, the second curved boom 134 is formed lever mould with rotating shaft 139
Type, according to lever principle, by depressing the second curved boom 134, so that the first curved boom 133 is lifted.Equally, when the shape of clutch-plate 131
Shape changes, then the shape of handle 121 also accordingly changes.
Fig. 9 and Figure 10 is referred to, in other embodiments, when the first curved boom 233 of clutch-plate 231 and the second curved boom
Angle between 234 is obtuse angle, when close to 180 degree.Then handle 221 is straight barrel type.Equally, handle 221 includes handle portion
224 with promotion part 223.Handle portion 224 opens up the fluting 229 to be formed and connected with promotion part 223.Handle portion 224 offers first
Fluting, the side wall of promotion part 223 offers the second fluting vertically.First fluting is connected to form linear with the second fluting
Fluting 229.Clutch-plate 231 is contained in handle 221 and is oppositely arranged with fluting 229.Clutch-plate 231 can enter from fluting 229
Go out.Elastic component 232 is connected between the second curved boom 234 and handle portion 224, and elastic restoring force is acted on to the second curved boom 234.Other
Element and its related content are essentially identical with scheme in present embodiment, repeat no more.
Hold with a firm grip handle portion 224, when the second curved boom 234 to clutch-plate 231 applies external force, the second curved boom 234 extrudes elasticity
Part 232, clutch-plate 231 239 is rotated around the shaft, according to lever principle, the first curved boom 233 is departed from threaded rod 213.Loose one's grip and remove
The active force to the second curved boom 234 is removed, the elastic restoring force of elastic component 232 rotates backward clutch-plate 231, makes the first curved boom
233 engage with threaded rod 213.
Therefore above-mentioned compression pump equally can be used one-handed performance in release, the course of work for taking out negative pressure, control clutch-plate
231 with the meshing relation of threaded rod 213, so as to reach the release of one-handed performance control pressure pump, take out negative pressure process, improve pressure
The convenience that pump is used.
Although describing the present invention with reference to several exemplary embodiments, it is to be understood that, term used be explanation and
Exemplary and nonrestrictive term.Due to the present invention can be embodied in a variety of forms without deviating from invention spirit or
Essence, it should therefore be appreciated that above-mentioned implementation method is not limited to any foregoing details, and should be limited in appended claims
