[Prior Art] A needle that can be separated from a syringe, or a syringe that is integrally formed with an injection needle, is covered with a needle cover at the outer edge of the injection needle. Therefore, when an action of extraction or injection is required, The needle cover must be removed from the needle or syringe and the needle should be inserted into the affected part of the patient and injected or extracted with a syringe. When the injection or extraction is completed, the needle cover must be covered back. Then I will abandon 'to prevent the needle from being exposed to danger; however, because the structure of this kind of application needs to remove the needle cover during extraction or injection, it is very easy to cause the needle cover to be lost, causing it to be discarded. The needle is exposed to the outside, which is dangerous, and since the needle cover needs to be covered after the injection is completed, at this time, if the medical staff is careless, the needle is easily injected and infected, and further, the needle of the conventional structure is used. Or a syringe is also easy to be used for secondary use. It can be seen that there are still many shortcomings in the above-mentioned conventional structure, which is not a good designer, but needs to be improved. In view of the shortcomings derived from the above structure of f, the inventor of the present invention has improved and innovated, and after the research of the main dragon, the sinking w, and the u heart (four), finally successfully developed the first syringe. Safety cover. S) 1308073 SUMMARY OF THE INVENTION It is an object of the present invention to provide a disposable syringe safety cover that is easy to handle and safe. A second object of the present invention is to provide a disposable syringe safety cover that avoids the use of an injection needle. Another object of the present invention is to provide a disposable syringe safety cover that allows the medical staff to confirm the hand behind the needle tip to prevent an injection hazard. There is a disposable syringe safety cover which can achieve the above object, and comprises a set of joints, wherein the sleeve portion is provided with a sleeve hole for the syringe to be inserted, and the top surface of the sleeve portion is connected by a shaft or two. a wider stopper on the side, and one or more hook portions are extended at the end of the stopper; a protective cover having a sliding slot formed on the protective cover, the inner edge of the sliding slot being close to the side or both sides The rear end is provided with a convex top portion to isolate the rear of the sliding slot from a receiving groove, and one or more perforations are opened on one side of the sliding slot, and the front end of the protective cover has a placement portion, and the placing portion An opening is formed on each side of the sliding cover. The top surface of the protective cover is provided with a stopping portion at the front end of the sliding cover, and the top surface of the protective cover is respectively provided with an abutting top at the rear end of the sliding groove. [Embodiment] Please refer to FIG. 1 , the safety cover for a single syringe provided by the present invention mainly includes: a set of joints 1 , and a sleeve hole 1308053 · 11 for inserting a syringe into the sleeve portion The top surface of the socket portion 1 is connected to a wide-width stopper 13 by a shaft 12, and one or more hook portions 14 are extended at the front end of the sleeve portion 13. The front end of the hook portion 14 has a front end a hook portion 141 is bent downward, and a leading edge 3 is formed at the bottom of the leading edge of the hook portion 14; a protective cover 2 having a sliding slot 2 丨 on the inner edge of the sliding slot 2 j or A convex top portion 22 is disposed at a position close to the rear end of the two sides to isolate the rear of the sliding slot 21 from a receiving slot 23, and one or more through holes 24 are formed on one side of the sliding slot 21, and the front end of the protective cover 2 is bottomed. An opening portion 251 is defined in each of the two sides of the mounting portion 25, and a top surface of the protective cover 2 is provided with a stopping portion 26 at the front end of the sliding slot 21, and the blocking portion is supported by a bump. And a leading edge 3 is formed on the upper edge of the rear end of the blocking portion 26, and the top surface of the protective cover 2 is respectively disposed at the rear end of the sliding slot 21 I arrived at the top of a 2. Referring to FIG. 1 , 2 , 3 and FIG. 4 , before the use of the primary syringe safety cover provided by the present invention, the sleeve portion is passed through the chute 21 from the bottom of the protective cover 2 by the stopper 13 . The hooking portion 14 of the front end of the stopper 13 is inserted through the through hole 24 of the side of the sliding groove 21 from the top surface of the protective cover 2 (as shown in FIG. 2 and FIG. 3), and the protective cover 2 is pivoted with the shaft 12 as the axis. Rotating, the hook portion 14 of the front end of the stopper 13 can be turned to the direction of the stopper portion 26 of the protective cover 2, and the sleeve portion 1 can be pushed backwards to make the shaft 12 on the socket portion pass the convex top portion 22 The cartridge is inserted into the trough 23 (as shown in FIG. 4). At this time, the syringe can be inserted into the sleeve hole 11 of the socket portion 1. 1308073,

When the action of extracting or injecting is to be performed, the personnel will rotate the protective cover 2 with the shaft 12 as the axis to make the syringe, and the main injection needle is opened by the placing portion 25. "51" is turned out, and when the protective cover 2 is rotated: the protective cover 2 can be "sucked (as shown in FIG. 5)" by the hook portion of the socket portion i to the top portion 2 to prevent medical personnel from performing the operation. When the action of the extraction or injection is carried out, the cover 2 is inconvenient to turn over. In addition, the protective cover may be provided with one or more convex portions 28 at a position close to the abutment 27 to block the hook portion 14. On the other side, the protective cover 2 is turned in place before injection (as shown in Figure 5); and when the extraction or injection is completed, the medical staff only needs to turn the protective cover 2 back to the original position, and then the protective cover 2 is pulled back, so that the shaft 12 of the socket portion 1 passes through the convex top portion 22 of the sliding slot 21 and is placed at the front end of the sliding slot 21, and when the shaft 12 is disposed at the front end of the sliding slot 21, the hooking portion 14 is also By sliding the stop portion 26 by itself and the guide angle 3 of the stopper portion 26, and hooking the front end face of the stopper portion 26 with the hook portion (4), the protective cover 2 is neither If the needle is retracted back, it cannot be rotated again (as shown in FIGS. 5 and 6). At this time, the injection needle tip of the syringe is bent against the front end of the placement portion 25, thereby causing the injection needle to be bent and deformed. Providing the secondary syringe safety cover to reach the injection needle and the present invention avoids the purpose of secondary use, and since the secondary syringe safety cover provided by the present invention is operated, the medical staff's hands are maintained After the needle tip is injected, the medical staff can be prevented from being stabbed.
