In the above structure, the number of the fixed plate 10, the spring 11 and the locking ball 12 is two, and the two springs 11, the locking ball 12 and the fixed ball groove 13 are symmetrically distributed on both sides of the infusion port 9.

[0022] In a preferred embodiment, a circular groove is provided on the top of the lifting sleeve 6, and the diameter of the circular groove is the same as the diameter of the limiting rod 5. The bottom end of the limiting rod 5 extends to the inside of the circular groove on the top of the lifting sleeve 6, and the limiting rod 5 is slidably connected to the circular groove on the top of the lifting sleeve 6. In the above structure, the limiting rod 5 extends to the inside of the lifting sleeve 6, so that when the lifting sleeve 6 is lifting, the limiting rod 5 limits the lifting sleeve 6, so that the lifting sleeve 6 will not rotate inside the rotating sleeve 4 due to external factors.

[0023] In a preferred embodiment, a slot is provided on the inner wall of the lifting sleeve 6, and an extension block is provided on the outer wall of the fixed needle plate 7. The extension block on the outer wall of the fixed needle plate 7 is matched with the slot provided on the inner wall of the lifting sleeve 6, and the extension block on the outer wall of the fixed needle plate 7 is slidably connected with the slot on the inner wall of the lifting sleeve 6. In the above structure, by aligning the extension groove on the outer wall of the fixed needle plate 7 with the slot provided on the inner wall of the lifting sleeve 6, the infusion port 9 and the fixed plate 10 at the top of the lifting sleeve 6 are vertically inserted into the inner wall of the transmitter 3.

[0024] In a preferred embodiment, a square groove is opened at the bottom of the transmitter 3 near the fixed plate 10, and the diameter of the square groove is the same as the diameter of the fixed plate 10. The fixed ball groove 13 is located inside the square groove at the bottom of the transmitter 3. In the above structure, the fixed plate 10 can enter the inner wall of the transmitter 3 through the square groove at the bottom of the transmitter 3, so that the transmitter 3 fixes the position of the fixed plate 10.

[0025] In a preferred embodiment, the number of locking balls 12 and fixed ball grooves 13 is two, and the two locking balls 12 and fixed ball grooves 13 are symmetrically arranged with the fixed plate 10 as the center. In the above structure, the two locking balls 12 are pressed in the direction of the spring 11 so that the two locking balls 12 move in the direction of the spring 11, thereby causing the spring 11 to contract, so that the locking balls 12 enter the interior of the fixed plate 10.

[0026] In a preferred embodiment, the diameter of the fixed ball groove 13 is the same as the diameter of the locking ball 12, and the height of the fixed ball groove 13 from the bottom of the transmitter 3 is the same as the height of the locking ball 12 at the bottom of the fixed plate 10. In the above structure, by placing the fixed plate 10 into the square groove at the bottom of the transmitter 3, the locking ball 12 is subjected to pressure when overlapping with the bottom of the transmitter 3, so that the two locking balls 12 move toward the inside of the fixed plate 10, thereby causing the spring 11 to contract, so that the locking ball 12 slides on the inner wall of the square groove at the bottom of the transmitter 3. When the locking ball 12 is aligned with the fixed ball groove 13, the locking ball 12 is bounced into the inside of the fixed ball groove 13 by the rebound force of the spring 11.

[0027] Working principle: when the device needs to be used, connect the input port with the liquid inlet 2, so that the medicine is transmitted to the transmitter 3 through the liquid inlet 2, and the transmitter 3 is transmitted downward to the inside of the fixed needle plate 7, and the fixed needle plate 7 is discharged through the steel needle group 8. The steel needle group 8 is placed at the place where injection is required, so that the steel needle group 8 pierces the skin on the surface of the human body and injects it into the skin. When the leakage length of the needle tip needs to be adjusted, rotate the rotating sleeve 4. The rotating sleeve 4 engages with the external thread of the lifting sleeve 6 through the internal thread, driving the lifting sleeve 6 to perform a lifting movement, so that the lifting sleeve 6 performs a lifting movement along the limit rod 5, so that the lifting sleeve 6 is lifted and lowered inside the fixed needle plate 7. The leakage length of the steel needle group 8 is determined by adjusting the height of the lifting sleeve 6 outside the steel needle group 8. When the steel needle group 8 needs to be replaced, the lifting sleeve 6 is rotated to the highest point. At this time, the fixed needle plate 7 leaks out, and the fixed needle plate 7 is held by hand. The needle plate 7 is pulled downward, so that the fixed needle plate 7 drives the fixed plate 10 to move downward, and the fixed plate 10 drives the spring 11 and the locking ball 12 to move downward. Through the pressure of the locking ball 12 and the fixed ball groove 13 when moving downward, the locking ball 12 moves toward the inside of the fixed plate 10, so that the locking ball 12 is hidden inside the fixed plate 10, and the fixed needle plate 7 is taken out of the equipment together with the steel needle group 8, and the unused fixed needle plate 7 and steel needle group 8 are taken out, and the fixed needle plate 7 is placed on the inner wall of the lifting sleeve 6, so that the fixed plate 10 and the infusion port 9 at the top are aligned with the square groove and the output port at the bottom of the transmitter 3, and the fixed needle plate 7 is moved upward, so that the fixed needle plate 7 drives the fixed plate 10 to move upward, so that the fixed plate 10 enters the square groove at the bottom of the transmitter 3, so that the fixed ball groove 13 is engaged with the locking ball 12, and the fixed needle plate 7 is fixed to replace the steel needle group 8.
