Among the figure, 1. button, 2. pen hanging, 3. percussion main body 4. bottle is grabbed, and 5. vial bodies is 6. protected needle guard, 7. protect the pin medicated cap, the 8. cap for brush, 9. catch, 10. push rod, 11. hickeys, 12. springs, 13. plugs, 14. syringe needle, 15. draw-in grooves, 16. oblique angle hooks, 17. little springs, 18. cassette mechanisms, 19. forms.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is elaborated.

As shown in Figure 1, it is the structural representation of this utility model full-automatic syringe, comprise percussion main body 3, percussion main body 3 is connected with vial bodies 5 by hickey 11, percussion main body 3 inwalls are provided with catch 9, the termination openings of percussion main body 3 also is provided with button 1, button 1 is connected with push rod 10 by cassette mechanism 18, be provided with little spring 17 between button 1 and the catch 9, be provided with spring 12 between catch 9 and the push rod 10, push rod 10 is grabbed 4 and is connected with bottle, bottle grab 4 be sleeved at the bottom of the cillin bottle on, be filled with Compressed Gas and medicinal liquid in the cillin bottle in advance, XiLin bottleneck has been connected with syringe needle 14, and syringe needle 14 is arranged on and protects in the needle guard 6, protects needle guard 6 and is provided with one and protects pin medicated cap 7, protect pin medicated cap 7 and will protect syringe needle 14 encapsulation on the needle guard 6, guarantee aseptic condition.Protect the port that pin medicated cap 7 passes vial bodies 5, the port of vial bodies 5 is provided with a cap for brush 8, plays the reinforcement shell effect that pin medicated cap 7 is protected in a protection.

As shown in Figure 2, be the structural representation of this utility model full-automatic syringe cassette mechanism.Among the figure, the oblique angle hook 16 of cassette mechanism 18 is elastomeric elements, oblique angle hook 16 can be stuck on the catch 9 when being connected with catch 9, little spring 17 is used for button 1 jack-up, the pressure that draw-in groove 15 is eliminated oblique angle hook 16, make oblique angle hook 16 freely uphold and be stuck on the catch 9, thereby can guarantee that spring 12 is in compressive state.When oblique angle hook 16 was connected with catch 9, boss was stuck on the catch 9; When the draw-in groove 15 of button 1 was pressed into oblique angle hook 16, oblique angle hook 16 was promptly thrown off with catch 9.
