[0025] Furthermore, the syringe 1 fixes and supports the needle tube 2, and by pulling the push plate 8, the push rod 9 and the push block 10 are driven, so that the medicine can be sucked into the syringe 1 through the needle tube 2. When injection is needed, the fingers can be pressed on the fixed grip 13, the palm of the hand can contact the grip 12, and the palm can push the grip 12 hard to achieve injection. The hand-held push injection can achieve a more stable injection effect.

[0026] The outer wall of the right end of the injection barrel 1 is fixedly connected with a fixing ring 4, and the front and rear sides of the bottom end of the fixing ring 4 are fixedly connected with adjusting belts 5. The end of the front adjusting belt 5 away from the fixing ring 4 is fixedly connected with a convex buckle 6, and the end of the rear adjusting belt 5 away from the fixing ring 4 is fixedly connected with a concave buckle 7, and the inner wall of the concave buckle 7 is clamped on the outer wall of the convex buckle 6.

[0027] Furthermore, the fixed ring 4 is fixedly supported by the syringe 1, and the adjustment belt 5 is wrapped around the patient's limb, and the convex buckle 6 is clamped in the concave buckle 7 to achieve connection and fixation of the adjustment belts 5 on both sides, so that the syringe 1 can be fixed on the patient's limb to achieve stable injection.

[0028] The inner wall of the slide groove 14 is slidably connected with a slider 15, and the bottom end of the slider 15 is connected to the limit plate 3 through a tension spring 17, one end of the tension spring 17 is fixedly connected to the middle of the top of the limit plate 3, and the other end of the tension spring 17 is fixedly connected to the left side of the bottom end of the slider 15.
