[0034] The specific working process of this utility model:

[0035] During use, the protective cap 6 is removed from the outer tube 51, and the adjustment knob 7 is turned. The adjustment knob 7 drives the syringe 41 to rotate through the support frame 2. The syringe 41 is observed through the observation window 11 until the syringe 41 for treating the corresponding injury is rotated to a position corresponding to the guide tube 521;

[0036] The inner tube 52 is aimed at the skin of the injured person by holding the tube housing 1 and pressed. The inner tube 52 slides in the outer tube 51 against the elastic force of the return spring 53. When the inner tube 52 slides until the guide tube 521 passes through the clamping sleeve 32 and contacts the elastic support baffle 321, the elastic support baffle 321 is opened. At this time, the elastic support baffle 321 releases the syringe 41. The syringe 41 slides toward the skin under the elastic force of the compression spring 45 until the needle 46 penetrates the skin to a certain depth, and the elastic clamping baffle 44 is received. The pressure of the guide sleeve 31 is applied to the syringe 41, and the elastic snap-fit baffle 44 is separated from the edge of the syringe 41. Under the elastic force of the compression spring 45, the piston rod 43 drives the elastic snap-fit baffle 44 and the piston block 42 to slide in the syringe 41, and the corresponding liquid medicine in the syringe 41 is injected into the skin through the needle 46. After the injection is completed, the syringe is separated from the skin, and the syringe 41 of the corresponding injection assembly 4 together with the needle 46 are taken out from the guide tube 521, and the protective cap 6 is covered, thereby completing the use of the syringe.

[0037] By pressing the skin to activate the inner cylinder 52 of the assembly 5, the elastic support baffle 321 in the locking assembly 3 can be released from the injection assembly 4. When the injection assembly 4 moves in the inner cylinder 52, on the one hand, the syringe 41 drives the needle 46 to penetrate the skin, and on the other hand, the elastic engaging baffle 44 releases the piston block 42 to achieve injection of the liquid medicine. Both the penetration of the skin and the injection of the liquid medicine are completed automatically, without the need for manual operation by professional medical staff. The injection efficiency of the syringe is high, and it is convenient and quick to use, which is more conducive to rescuing the injured and sick.

[0038] The support frame 2 is connected to a conversion knob 7, and an observation window 11 is provided on the tube shell 1.
