DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to an injection syringe, and more particularly to a novel safety syringe that prevents secondary use. [Prior Art] As far as we know, most of the conventional safety syringes have a large-sized and small-sized card that protrudes from the front end of the rod to match the structure of the engaging groove at the bottom of the needle holder. However, if the design is too large, it is not easy. Wearing a person, too small is conducive to wearing a person to engage the groove, but can not smoothly pull the needle set back, so the precision of the structure is higher. The reason is that the industry has reversed the design of the protrusion of the front end of the push rod, the extension of the bottom end of the needle set and the hook of the snap groove. The safety syringe of this type is shown in the sixth figure. U.S. Patent No. 91,132, 968, which is referred to as the prior art, a) the syringe of the prior art is mainly provided with an engaging groove 51 at the front end of the plunger body 5 to penetrate the bushing 52 The end extending engaging legs 5 3 are hooked and combined to achieve the purpose of secondary use of the needle back to the syringe, but the prior art is to make the plunger body and the bushing engagement relationship more stable, and the engaging legs 5 3 Then, a rear end portion 5 4 is extended outwardly, and the design of the rear end portion 54 is also caused by the fact that the engaging groove of the plunger body cannot be quite smooth and the design of the engaging card is missing. As shown in the seventh figure (the second figure of the new patent of the Republic of China Patent Application No. 80200493, hereinafter referred to as the prior art 2), the prior art 2 mainly passes through the radial grooving of the front end of the plunger 1 〇6. 1 18Abuts to the base 1 1 1 The central conical projection 200817059 The object i14 'By the tapered projections, the radial slots 1!8 are opened and the teeth are engaged, that is, the lunar shackles the base and the injection needle firmly. Pump into the syringe. The π 技 云 ° 又 又 又 又 本 本 本 本 本 本 π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π π When the bottom end pushes the person, it is subjected to the radial grooving of the slanting _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In addition, the plunger is applied with a large thrust and is inserted into the base to engage with the base. The push surface of the pin will be moved over the base 1. The inclined taper at the bottom of the socket will come out along the slope of the inner wall of the protruding nozzle. The result is that the surface 2 is detached; 'the base of the technique 2 and the socket are sucked back to form a projection on the injection surface. Therefore, the cloud is in the wire 6 "suspecting the angle", and the overall design is very hard. It is not humanized, so it is necessary to improve it. Ke only [invention content] 'newness == is provided - kind of paste and both stable - the needle set is for the above purpose, the push of the safety device of the present invention The front end of the rod protrudes - the engaging body, the body of the shaft is inserted into the body of the second and second cylinders at the top edge of the injection, and the spider is used for the lion's ground, and the joint is made from the middle material W. When the lower end is connected, the central axis extends a conical convex body, and the conical convex body when the push rod is pushed against the adapter can easily wear the second bayonet body to the physical property, and at the same time, the abutting portion of the engaging body 6 200817059 The adapter side reads the side of the card to make a turn, the paste turn and the needle flank fast set card (10) structure 贞 'X can turn the needle to turn the song carving card _ New effect. [Embodiment] The reviewer will have a better understanding of the structural features and the efficacies of the present invention.

In use, as shown in the second and third figures, when the push rod 2 is pushed against the adapter 41 of the hole w: the engaging body 3 of the push rod 2 〇 protrudes from the front end 3 2 is engaged in the joint The groove 4 4 3 wall positioning groove 4 4 3 i, the clamping mode is a slotted protrusion 4 4 i extending through the joint to the T, and the card slot 3 is worn by the body. The tapered design fits the axial direction of the slot 31. The groove 3 3 'forces the two semi-circular body of the engaging body 3 to extend the groove 4 4 3 in the direction of the wall surface to make the abutting portion 3 of the top edge of the engaging body 3 Q The locking relationship with the positioning groove 4 4 3 1 is more stable; and the manner shown in the fourth figure is applied to firmly pull the needle set away from the hole i 3 and fall into the syringe when the push rod 2 is pulled back. In the chamber 12, the protrusion can be abutted against the piston by the protrusion on the lower edge of the joint portion, and the needle is offset to the side to break the push rod 2 Q, although the heart is 'recycling the waste sister shot twice The use of the situation happened. Another example is the fifth ride; ^ ‘If you accidentally cover the body 4 3, you can reach the needle set back 8 200817059 Pumped to the syringe!
