When fixing, the syringe 1 is placed in the fixing ring 93. At this time, the first clamping block 96 and the second clamping block 98 on the outer surface of the support rod 95 initially limit the syringe 1. Then, through the elastic force of the third spring 92, the fixing ball 97 further squeezes and fixes the syringe 1, improving the stability of the syringe 1 during use, preventing the syringe 1 from slipping and improving the practicability of the overall device.

[0024] Further, the first connecting member 31 and the second connecting member 39 have the same size. The card slots 36 are equally spaced on the outer surface of the first fixing block 35. Through the arrangement of the card slots 36, the balls 37 can be clamped to prevent them from falling off.

[0025] Further, the balls 37 are equally spaced on the inner surface of the second connecting member 39. The outer surface size of the balls 37 matches the inner surface size of the card slots 36.

[0028] Furthermore, the first micro cylinder 51 and the first push plate 52 form a telescopic structure. The first micro cylinder 51 and the second micro cylinder 53 are symmetrically arranged with respect to the width central axis of the housing 4. Through the arrangement of the first push plate 52, under the cooperation of the first micro cylinder 51 and the second micro cylinder 53, the stability and accuracy of the syringe 1 during the injection process are ensured. The first micro cylinder 51 is responsible for pushing the first push plate 52 to perform a return movement, enabling the push block 2 to return to its position smoothly.

[0029] Working principle: During use, first, the syringe 1 is installed on the housing 4 through the fixing mechanism 9 to ensure the stability of the syringe 1. Subsequently, the injection mechanism 5 is activated. The second micro cylinder 53 drives the second push plate 54 to move through telescopic movement, pushing the push block 2 inside the syringe 1 to inject the medicine through the syringe 1. After the injection is completed, the first micro cylinder 51 is activated to drive the first push plate 52 to move, causing the push block 2 to return to its position to prepare for the next injection. During the injection process, the supplementary light lamp 7 emits light for auxiliary determination to improve the determination accuracy. At the same time, the determination lamp 87 in the determination mechanism 8 can be rotated for determination as needed. Through the rotational connection of the bearing ball 82 and the rotating shaft 83, and the protection of the protective sleeve 84, the safety and stability of the determination lamp 87 during the rotation process are ensured. The fixing mechanism 9 fixes the syringe 1 in all directions through the elastic force of the third spring 92 and the extrusion fixation of the fixing ball 97, preventing it from shaking during the injection process and improving the precision and stability of the injection.
