[0020] In the embodiment, the novel device can be adsorbed on the skin surface of a patient by the silica gel base 1 and the support frame 11. Two support frames 11 are symmetrically installed on the silica gel base 1, and a movable frame 2 is arranged between the two support frames 11. The movable frame 2 is symmetrically provided with two syringe limiting plates 21 at the top, and a through slot 22 is formed at the top of the movable frame 2. The movable frame 2, the syringe limiting plates 21 and the through slot 22 form a component for limiting the syringe, so that the syringe is vertically placed between the two support frames 11. First connecting plates 23 are fixedly connected to the two sides of the movable frame 2, and connecting springs 3 are arranged at the bottom of the first connecting plates 23. A second connecting plate 31 is fixedly connected to one side of the silica gel base 1, and the connecting springs 3 connect the first connecting plates 23 and the second connecting plate 31. The syringe is limited before injection. The movable limiting frame 4 is detachably connected to one side of the silica gel base 1 and movably connected with the movable frame 2. The movable limiting frame 4 limits the injection depth of the syringe. Before the patient is injected, the injection depth of the needle is determined to be between 2.5-3 cm according to the age, body size and other conditions of the patient. In the novel device, the support frame 11 is provided with a corresponding length scale. The movable limiting frame 4 is installed in the corresponding position of the inner wall of the support frame 11 through the clamping block 42 and the clamping groove 421. In the novel device, a plurality of clamping grooves 421 are formed in the inner wall of the support frame 11 at the corresponding scale positions. Then, the device is adsorbed on the injection position through the silica gel base 1. Then, one end of the syringe is placed inside the two syringe limiting plates 21, and the needle of the syringe penetrates through the through slot 22. The medical staff starts to inject the patient. The medical staff holds the syringe to perform intramuscular injection on the patient, so that the syringe continuously moves downward. In the process of downward movement of the syringe, the movable frame 2 moves downward, thereby driving the two first connecting plates 23 on the two sides of the movable frame 2 to slide in the sliding groove 12.
