Wall connects, and forms an annular attached bellows cavity volume, is provided with easy breakpoint, described easy breakpoint on described attached bellows cavity volume
Position is corresponding with described thimble position.
During use, when operator's hand-held handle, when promoting piston shaft inward, piston plate promotes liquid to enter breast
Head through syringe needle exhaustjet device outside, the thimble on piston plate move closer to attached bellows cavity volume and final from fragile pricking method
Enter, because now easy breakpoint is blocked by thimble completely, liquid may not flow into attached bellows cavity volume, but because easy breakpoint is pierced
Broken, after piston plate drives thimble to exit attached bellows cavity volume, leave hole on attached bellows cavity volume, if syringe is again
During using drawing liquid, liquid can be flowed in attached bellows cavity volume by this hole and waste.
Preferably, the quantity of described thimble is two, and the quantity of described easy breakpoint is two.It is so designed that and can make thimble
Stress balance when stabbing attached bellows cavity volume, Stability Analysis of Structures.
It is preferably located at described piston plate and teat placement is provided with filling projection.Filling is raised further will
Nipple pushed to by liquid, so that liquid is discharged completely.
Preferably, described nipple is located at the centre of described round barrel cover.It is also preferable that described nipple is located at described circle
The off-center position of cover.When the diameter of round barrel cover is less, nipple is arranged on the centre of round barrel cover, can effectively carry
High structural integrity, reduces manufacture difficulty, easy operation.It is also preferable that described nipple is located at the off-center portion of round barrel cover
Position.When round barrel cover is when being relatively large in diameter, nipple is arranged on the off-center position of round barrel cover, can conveniently inject, and so that syringe needle is held
Easily parallel with human vas.
Preferably, described piston plate, piston shaft and handle, three is connected by adhesive.It is also preferable that described work
Seben, piston shaft and handle, three in one is molded.
Compared with prior art, the beneficial effects of the present invention is：Structure is simple, and cheap, self-destruction effect is good, can have
Effect prevents recycling of syringe.
