Compared with traditional intravenous injection, intramuscular injection of drugs is limited by the absorption capacity of muscles. Usually, the amount of drugs injected intramuscularly is small, and because the drugs are absorbed into the blood through the muscles, the onset of action is slower. However, it is simple to operate and suitable for patients with underlying diseases or their families to operate by themselves. However, there are huge safety hazards in the used needles.

[0035] Before use, the device of the present invention is connected to a power source, and the powered adsorption ring 27 and the induction plate 29 are both powered on, and the induction plate 29 establishes a signal connection with the powered adsorption ring 27. At this time, the powered adsorption ring 27 adsorbs the adsorption tube 22 under normal conditions; the upper pressing insertion plug 5 is pulled out and separated from the induction feedback component 6, and the pressing and pushing rotating component 2, the insertion follower component 3 and the limiting clamping component 4 are replaced as a whole and placed in the wrapped outer tube 24 of the induction adsorption component 20, and the fixed notch 55 at the bottom of the outer wrapped tube 12 of the limiting clamping component 4 is clamped with the bottom The fixed protrusion 30 of the ring 25 is engaged and fixed, ensuring that the sliding area of ​​the inner wall limiting slide 13 coincides with the projection range of the sensing plate 29.

[0036] When the user uses it, he pulls out the wrapped protective sleeve 58, holds the hand grip ring 26 of the device and inserts it to the muscle injection site, and inserts the insertion needle 11 into the muscle. During the injection process, the user does not hold the upper pressing insertion plug 5 and the adsorption fixing part 19, but only presses the upper pressing insertion plug 5. In the process of the pressing tube 15 moving downward, the contact protrusion 17 pushes the pressing contact plate 35 and the rotating disk 34 to move downward, and the rubber plug 46 pushes the liquid medicine in the liquid medicine placement tube 9 to be discharged. In this process, the special-shaped insertion rod 16 is inserted and moved downward in the special-shaped insertion slot 23, and the external card sleeve pipe fitting 40 moves downward along the outer wall of the liquid medicine placement tube 9, driving the support limiter 42 to move downward, and the sliding short shaft 48 moves in the vertical slide groove 56. When sliding downward, when sliding to the connection between the vertical slide groove 56 and the spiral slide groove 57, the height of the induction sheet 49 in the sliding short shaft 48 is fed back to the induction plate 29, and the energized adsorption ring 27 connected to the signal of the induction plate 29 stops adsorbing the adsorption tube 22. In the process of the sliding short shaft 48 moving downward, due to the restriction of the spiral slide groove 57, the external ferrule fitting 40 is driven to rotate, and the pressing and pushing rotating component 2 is rotated as a whole, driving the external upper pressing insertion plug 5 and the adsorption fixing part 19 to rotate and slide in the induction adsorption part 20. In the process of the pressing and pushing rotating component 2 rotating as a whole, the user's pressing hand rotates along with the pressing and pushing rotating component 2 to avoid accidents during the rotation process. At the same time as the jam occurs, it provides a rotation direction guide for the user's autonomous rotation in the next step. When the sliding short shaft 48 slides to the bottom of the spiral slide groove 57, the bottom of the rubber plug 46 fits the bottom of the medicine placement tube 9, the medicine is completely discharged, the support spring 33 is completely compressed, and the bottom engaging block 44 moves to the insertion port of the wrapped engaging groove 51 of the bottom follower ring 10. The user fixes the induction adsorption part 20, rotates the upper pressing insertion plug 5, drives the pressing and pushing rotating component 2 to rotate, and screws the bottom engaging block 44 into the wrapped engaging groove 51 until the bottom follower ring 10 is driven to rotate and move. The wing-shaped engaging block 52 at the bottom of the bottom follower ring 10 moves with the rotation and disengages from the T-shaped engaging groove 1 4. The engagement restriction of the wing-shaped engaging blocks 52 forms a relatively fixed state between the insertion follower component 3 and the pressing and pushing rotating component 2. The operator releases the upper pressing insertion plug 5. Under the reset action of the supporting spring 33, the supporting rotating disk 34 and the outer wrapping tube 12 are separated. The insertion follower component 3 is dragged upward, the bottom follower ring 10 is dragged up, and the insertion needle 11 is dragged into the outer wrapping tube 12 to hide the insertion needle 11. When the sliding short shaft 48 slides into the vertical slide groove 56, the induction plate 29 feeds back the height of the induction sheet 49, and the energized adsorption ring 27 adsorbs the adsorption tube 22 again. The user pulls out the upper pressing insertion plug 5 and takes out the replacement as a whole to facilitate the next use.
