At this time, since the surface of the clamping protrusion 241 facing the direction of the pressing part 23 is a slope 2412, when the medical staff put the operating part 1 behind When pulling, the front edge of the positioning groove 15 of the operating part 1 can smoothly slide over the slope 2412 of the locking protrusion 241, so that the locking protrusion 241 is separated from the positioning groove 15, and the operating part 1 can be pulled backward. At the same time, Because the two pressing parts 23 and the two pressing elements 13 are all connected to the operating part 1 and the outer sleeve 2 at one end facing away from the operating part 1 and the front end of the outer sleeve 2, when the medical personnel press the two pressing parts 23 to utilize the two pressing elements 13 When fixing the vaccine needle, the two pressing parts 23 and the two pressing elements 13 all press down the vaccine needle 3 toward one end of the front end of the operating part 1 and the outer sleeve 2, and the other end facing away from the front end of the operating part 1 and the outer sleeve 2 The condition of being connected with the operating part 1 and the outer sleeve 2 causes the two pressing parts 23 and the two pressing parts 13 to both present a tilted state in which the front end is under pressure. Therefore, when the medical staff pulls the operating part 1 back, the two pressing parts 23 and the second pressing element 13 will slide and separate along the inclined slope, so that the second pressing part 23 no longer presses the second pressing element 13, so that the operating member 1 can be pulled back smoothly.

And because the stopper 31 of the vaccine needle 3 is accommodated in the accommodating groove 111 of the operating part 1, therefore, when the operating part 1 is pulled backward by the medical staff, the vaccine needle 3 is also driven by the operating part 1 to move backward. , so that the injection needle 32 at the front end of the vaccine needle 3 breaks away from the injection part of the subject and enters the outer sleeve 2. Then, the medical personnel continue to pull the operating part 1 backward, so that the elastic positioning part 24 of the outer sleeve 2 The clamping projection 241 enters the clamping groove 16 of the operating member 1. At this time, since the other side of the clamping projection 241 opposite to the inclined surface 2412 is a vertical clamping surface 2411, the clamping groove 16 faces the direction of the positioning groove 15. Surface 1 is the vertical abutting surface 161. Therefore, when the clamping protrusion 241 enters the clamping groove 16, if the outer sleeve 2 is to be pulled backward or the operating part 1 is pushed forward, the clamping surface 2411 will be in contact with the abutting surface 161. The top surfaces 161 are against each other, so that the safety vaccine injection needle provided by the present invention can no longer pull the outer sleeve 2 backward or push the operating part 1 forward, so that the injection needle 31 at the front end of the vaccine needle 3 is kept covered.
