The pen clip 10 that shell 12 is engaged；It is provided with the bottle container 23 and is fitted into the bottle container 23 and is screwed into main connector 11
Interior liquid medicine bottle 22；The left end of push rod 9 is docked by the button 7 of setting with the plug of described one end of liquid medicine bottle 22.
Operation principle：
Metering regulation
A) when the regulation of increase scale：Stubborn hopper 6 clockwise, can from form 17 mouthfuls see that scale increases one by one
Plus, main connector 11 is fixed together with shell 21, and lower driver 8 and main connector 11 are locked in a rotational direction, Zhi Nengzuo
It is axially moved, lower driver 8, ratchet 18 are locked in direction of rotation, can only be moved axially, pushing cylinder 16 and unidirectional tooth
The tooth of wheel 18 is killed together in the clockwise direction, and gear connects cylinder 5 with pushing cylinder 16 due to muscle groove matching relationship, causes gear to connect cylinder
5 can only axially move with pushing cylinder 16, and direction of rotation is locked, so during increase scale regulation, pushing cylinder 16 is motionless, two-way bounce tooth
Wheel 4, gear are connected cylinder 5 and killed together due to tooth, so two-way bounce gear 4, gear connect the relative without motion of cylinder 5, by
In little spring 2, tooth is not killed at this moment for two-way bounce gear 4, hopper 6, so having between two-way bounce gear 4, hopper 6
Bounce.Wherein, the part axially moved has caudal peduncle 1, little spring 2, capping 3, two-way bounce gear 4, gear to connect cylinder 5, hopper 6；Only
Making axially dynamic part without spin has two-way bounce gear 4, gear to connect cylinder 5.
When B) reducing scale regulation：If step A regulations are excessive, now need to adjust back scale, metering is turned counterclockwise
Cylinder, it can be seen that scale reduces one by one, correlation is as described in A, the difference is that the tooth of this side up pushing cylinder 16 and 18 is not
Locking, there is spring trend, but the tooth that driving force is insufficient to allow between pushing cylinder 16 and ratchet 18 is mutually beated, so pushing cylinder 16
It is now also motionless as step A, because in rotate counterclockwise, bounce gear 4 and the tooth of hopper 6 are locked, so two-way bounce
Gear 4, hopper 6 are without mutual rotation, and now to connect the tooth of cylinder 5 not locked for two-way bounce gear 4 and gear, so two-way bounce gear
4th, between connecting cylinder 5 tooth bounce occurs for gear.Wherein, the part axially moved has caudal peduncle 1, little spring 2, capping 3, two-way bounce gear 4, tooth
Wheel connects cylinder 5, hopper 6；Only making axially dynamic part without spin has 5.
Injection
During injection, (syringe needle, liquid medicine bottle are all installed correctly) presses caudal peduncle 1, now hopper 6 will be rotated counterclockwise, can
To hear continuous " rattling away " tooth bounce sound, when caudal peduncle 1 is pressed down on, compared with adjusting back scale step B, little spring 2 is pressed
Most short, and two-way gap of the bounce gear 4 without bob is reduced to, now two-way bounce gear 4, gear connect between cylinder 5 due to tooth
Presence, locked in direction of rotation, upper driver 15 is motionless, and meter 6 and upper driver 15 have screw-driven relation.Promote
When, meter 6 makees forward travel counterclockwise, and gear connects cylinder 5, hopper 6 and there is tooth occlusion, and pushing cylinder 16 has keyway with push rod 9
Matching relationship, now part 9 make counterclockwise movement, in summary, two-way bounce gear 4, gear connect cylinder 5, hopper 6, push rod 9,
Pushing cylinder 16, one acts as counterclockwise movement, and due to there is screw thread matching relationship between lower driver 8, push rod 9, and lower driver 8 is not
It is dynamic, the rotate counterclockwise of push rod 9, so push rod 9 can make forward travel, so as to promote button 7 to inject liquid medicine.Wherein, axially move
Part has caudal peduncle 1, little spring 2, capping 3, two-way bounce gear 4, gear to connect cylinder 5, hopper 6, button 7, push rod 9, ratchet
18；Only making axially dynamic part without spin has caudal peduncle 1, button 7, ratchet 18, and only rotating the part without axial direction has pushing cylinder 16.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
