[0024] In this embodiment, the main body shell 18 has two lead screws 7 rotatingly fitted inside.

[0025] In this embodiment, an electromagnet 26 is installed at one end inside the main body shell 18, an electromagnetic push-pull rod 25 is installed at the output end of the electromagnet 26, a needle retainer 24 corresponding to the needle 1 is installed at one end of the electromagnetic push-pull rod 25, and a needle stabilizer 20 corresponding to the needle 1 is installed at one end of the needle stabilizer connecting rod 21. Specifically, a connecting rod stabilizer 23 is installed at one end inside the main body shell 18. Two connected slots are opened at one end of the main body shell 18 and the middle of the connecting rod stabilizer 23. The electromagnetic push-pull rod 25 and the needle stabilizer connecting rod 21 are slidably engaged in the two slots. Through the two slots, the electromagnetic push-pull rod 25 and the needle stabilizer connecting rod 21 are slidably engaged in the two slots, thereby realizing the injection into the skin or controlling the depth of the needle 1 injection into the skin.

[0026] Operating steps: When injecting medication into the user's skin, first introduce the medication into the syringe 4. After introduction, place the needle stabilizer 20 on the user's skin to be injected. Then, manually rotate the depth adjustment rotor 13, causing the depth adjustment rotor 13 to drive the other lead screw 7 to rotate synchronously. This causes the other lead screw 7 to engage with the scale display block 14, thereby driving the scale display block 14 and the needle stabilizer connecting rod 21 to move horizontally in sync. At this time, the needle stabilizer connecting rod 21 slides in one slot and one groove, allowing adjustment of the injection depth of the needle 1 into the skin according to the user's condition. After adjustment, the electromagnet 26 is activated via the control circuit board. The electromagnet 26 then drives the electromagnetic push-pull rod 25 to move horizontally, causing the electromagnetic push-pull rod 25 to drive the electromagnetic push-pull rod 25 to move horizontally in sync. The pull rod 25 and the needle holder 24 move horizontally in sync, so that the needle holder 24 pushes the needle 1 quickly. At this time, the needle holder 24 slides in two other slots to realize the rapid injection of the needle 1 into the skin. At the same time, the stepper motor 15 is started by the control circuit board, so that the stepper motor 15 drives its lead screw 7 to rotate, so that the lead screw 7 is threadedly engaged with the pusher connecting rod 6. Thus, the pusher connecting rod 6 drives the pusher 5 to move horizontally in another slot. At this time, the pusher 5 pushes the liquid medicine in the syringe 4 and introduces it into the needle 1 through the catheter 2. At the same time, the liquid medicine is introduced into the user's skin through the needle 1 to realize the injection of liquid medicine into the skin. At the same time, after each operation, the limit switch 11 makes the stepper motor 15 return to the origin for calibration.
