Description of the invention: [Technical field to which the invention pertains] The present invention relates to a syringe, a special-purpose finger-type single-use type safety syringe. [Prior Art], according to a full-sized syringe, as disclosed in the Republic of China Application No. 942〇2948, the new art n patent can be used to secure the contact seat (4), which is made up of an elliptical base with a variable wall surface. The seat is matched with the funnel-shaped pushing portion of the front end of the push rod, and when the pushing portion is pushed into the connecting portion of the base j, the short wall of the variable wall surface of the elliptical base is expanded, and the wall surface expansion deformation is the same as that of the π moving wire. (4) Set up a safety syringe for the copper base to be connected to the syringe to form a single use in the syringe. On the touch of the self-small county ship and the front-end material _ chest design of the safety shot □,,; with the traditional circular pedestal and the retraction into the syringe, but still have structural design The completeness of the cockroach, including: From the first _ _ 〇 〇 可 可 可 可 可 可 可 可 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射 注射Pushed by the putter to the valley. Lame, only the tiny area at the bottom end is in contact with the wall of the housing. - But the medical staff S is looking for the _ to the end of the ray to turn the younger force, the deeper the funnel-shaped urging part will be The size of the variable growth of the secret seat is increased and the shape of the stalk is removed from the valley. The residual agent in the syringe is pushed by the rubber collar, so that the red hole is placed in the gap of the outer wire. Formation of Pharmacy 5 200817060 Drug waste that cannot be completely injected. ...in addition, "first read the art for the pedestal easy to wear to locate in the accommodating part, especially the ellipse open" pedestal outside the total length of the cymbal ring in the small bumper ring convex, hybrid funnel-shaped push & «+ and the expansion of the contact receiving part wall design, the material is lost - the novel and practical illusion ignores the relationship between the base and the receiving part wall contact and retraction, is the front end of the putter (four) financial wire shot __The best thickness _, so that the size of the push-up portion is too large to reduce the wall thickness of the base (4) surface, and the pedestal and the surface of the P-surface are lost. Tight 8, sexuality and easy to grow the above-mentioned medicine age The gap between the person's accommodating part and the thin wall thickness cannot be combined with the top flip hook, so that the push rod and the base are easily separated from the missing when the pumping is reversed. Conversely, if the variable wall thickness is too thick, the base deformation Plastics··Reducing the life, and affecting the operation smoothness of the pedestal lining of the needle body. SUMMARY OF THE INVENTION The present invention is mainly for the purpose of providing an injection for preventing the penetration of the drug. Incomplete novel safety syringe. Another object of the present invention is to provide a movable base cap body in a syringe A safety syringe for achieving the above-mentioned object, comprising: - a syringe, the cylindrical syringe for forming a communication 1. The second end, the first end is provided with a space for receiving the second end of the finger portion, and the wall surface of the tolerance space is an oblique guide surface which is tapered toward the second end σ - The movable base, the first part is for the needle body, and the second part is for the formation of 200817060 £:=::=::= A push rod' end is provided with a front end of the pressing portion to form a piston portion, and the piston portion is Set a rubber sleeve 'the front end of the rubber sleeve is convexly--combined with the rubber riding _ heart card, the most fibrous line of the oblique ship, the glutinous rice 彳 彳 =
