Description of the new type: [Technical field to which the new type belongs] The improvement and improvement of the female full syringe before the pusher, especially-a kind that only needs to be penetrated by the first month and matched with the needle holder. Under the simple structure design, it can achieve syringe safety and self-destruction. It can be used in the field of medical syringe technology.丄 夂 Efficacy of use, [Prior technology] Constructed from " === A structure that can be used to prevent heavy cranes from moving at full-time and full-time, its ^ 3;! 〇 "Twist_-type safety injection needle "Cylinder" is the new patent of the above-mentioned two female full syringe. ^ The above-mentioned twist-retractable safety injection syringe, yes, it is formed with a hook at the front end of the barrel, which is connected to the needle: convex :: the needle connector seat is formed with an axial rear end plus ^ = sub-axis W ， 俾 彻 _ 彻 嶋 _ Department penetrates into the convex cones of several convex tooth joints distributed on the cone surface of the conical cap of Rong Er. The claws are clicked. Inside, and through the skewed ya pressure rod of the towel 1_, pull the needle to the barrel to connect the mount to the non-direct narration of the mount, so that the turn can be reused. …, Ran-ren However, in order to achieve the use of the syringe can be re-used, the technical methods adopted, the Wei Quyu shooter has been repeated thoroughly, as the overall structure design aspects Defects to be improved: Among them, it can be found from the butterfly in the conventional patent specification that the claws of the seated dragon are prevented from turning from the flat mouth to the convex particles: the groove is designed by the claw structure. From the point of view, the structure is complicated. In addition, the needle connection seat ring design and the tapered cap ring at the front end of the push rod are engaged with each other to drive the needle combination seat to rotate away from the syringe. The structure of plastic injection molding with too complicated structure is becoming more and more obvious, and the processing cost will be passed on to the cost in the future. This design will no doubt reduce the market power. Further, 'the turning lever is intended to be inserted into a needle, and the accuracy of its bias is also taken into consideration, so as to avoid causing the upper edge of the job to be read, and it is impossible to reach the inside of the needle.' In addition to its overall structure, its For the purpose of making the needle-liner combined seat tilted and beneficial for repeated use, 'the convex teeth of the tapered cap and the concave teeth in the needle combination seat must be locked and turned away', and then the miscellaneous pressure rod extended by the front view of the tapered cap The phase is formed by one-way pressure, so it is obviously too complicated and there is room for improvement. _ [New content] The reason is ‘this creation is to improve Xi Zhilang ’s combination seat and putter combination back to the self-destruct society

When the putter rotating part of the domain is formed, the front end of the T is used to solve the problem. Into the outer part = the push-up part of the tender force day __ Tsuzaki's heart is close to the shape, complex Γ thin back-end Lai-head big body slave capacity _, in the state of wealth, when the hook teeth pass through the valley and the hole is indented in the shape 'When the head is to be pushed, the hook body is elastically reset to the external shape again.' As for "the above-mentioned effects of this creative system and other detailed technical means of progressive performance", they will be combined with each other and described in the embodiments described below. [Embodiment] Please refer to the first picture for the plunger of the creative syringe and the plunger using the plunger. 'The syringe includes: — the needle room (10), which is a hollow cylinder. The front end of the syringe (10) is formed with a needle socket (ii), and the end is extended outwards-an enlarged push spring pull portion (12), and the syringe (10) is formed with a penetrating accommodation. Hole (Work 3), Needle Socket (!!!) _ Accommodate the hole wall of hole (i 3) and form a ring, & (1 4) '俾 利-Needle seat (3 〇) forms a snap-in position when inserted The push rod (20) is placed in the syringe (work 0) by the push-pull part (12) in the direction of π and slides back and forth in a straight line in the hole (i3). And formed with a push-shaped pressing portion (2 丄) slightly larger than the push rod and the accommodation hole, a pressing portion (2 2) formed at the front end, and a hook body (2 2) extending from the front end of the pressing portion (2 2) 2 3). The hook body (2 3) includes a main rod portion (23 3 workers) and a pushing portion (2 3 2), between the main rod portion (2 31) and the pushing portion (2 3 2). And co-constructed-Ministry of Space (2 M281642) ' At present, the main lever portion (2 31) and the pushing portion (2 3 2) of the hook body are in an outwardly expanded shape; the above-mentioned main lever portion (2 3) is directed outward by the pressing portion (2 2). —The body extends and pushes. K 2 3 2) is integrally extended from the top-side of the main lever portion (2 31) inclined downward, and the push portion (2 3 2) and the main lever portion (2 3 i ), The space section (2 3 3), provides the tight work room required for the pushing section (2 3 2) to be squeezed by the lateral force, so that the main rod section and pushing section that are originally flared at one end. , Temporarily abut each other; 'a needle (30), which includes a needle base (3; [) and a needle body (32), the needle base (31) is a circular block, the outer edge is preset A positioning groove (3 1 1) is formed to be able to be positioned on the needle socket (1) in cooperation with the ring protrusion (1 4). The front shaft center is covered with a needle (3 2), and the rear shaft center is formed with a hook body. (2 3) The receiving groove portion of the extending hook; please cooperate with the second and third figures as shown in the figure. The receiving groove portion includes a small guide hole (3 3) on the outer side and a guide hole (3 3) an inwardly expanding head end hole (3 4), wherein the lateral diameter of the guide hole (3 3) It is designed to be slightly larger than the maximum outer diameter of the pushing part and the main rod when they are pressed against each other, so that when the hook body passes through the guide hole (3 3), it has an internal compression shape (shown in the third figure) ), After going deep into the guide hole (3 3), the pushing part (2 3 2) enters the head end hole (3 4) which is almost semi-circular arc shape, and then recovers and expands; refer to the fourth As shown in the figure, because the internal space of the head end hole (3 4) is wider than the guide hole, the hook body (2 3) is temporarily close through the guide hole, and the side is suddenly lost by pushing M281642 3 2) Squeeze the force to be elastically reset, so that the main part of the push-back plate is restored to an outer green, and it is returned with a na rod (2 Q). The hook body (2, 3) and the head end hole (3 4) are stuck to each other. …; And the hook body (2 3) under the free shape, the pushing portion (2 3 2) is outwardly extended relative to the main rod portion (2 31), when it extends into the head end hole At (3 4), the pushing part can just abut against Yin Qin's end hole, and the biasing force is generated on the entry side; • ▲ Reference to the fifth figure, when the push rod (20) is pulled out , The putter (2 〇) the hook body at the end of J (2 3) and the needle The holder (3 workers) accommodates the groove into a hook shape, so that the needle holder (3 1) will be pulled out of the sugar candy holder (Work 1) 'needle holder (3 1) with the push rod (2⑻)-but off the needle socket. (丄 丄), the hook body (2 3) knows that the needle seat (3! Side deflection springs against the force of force), it will force the needle (30) pulled back in the syringe (10) to automatically shift. Therefore, if the push rod is pushed in again, the needle structure will be damaged; the reason is that, even if there are people who want to recycle and reuse, they ca n’t put the (2 Q) Lin needle position in the groove. That is, the safety effect of preventing the syringe from being reused. -Oblique overturning forward view extension-Observable, ship's hook body (2 3) design 'combined with needle Gu (31) rear end of shaft hole to form a large and small accommodation groove, that is, a secret structure element Reaching the needle of the shaft, and the safety and self-efficacy of the needle after the retracted needle cannot be re-made. The extremely simplified structure design of this creation can reduce the safety of the syringe, which means that the cost of the syringe can be effective. In fact, it has both the efficiency and the turning point of market words.
