The bolt and the threaded hole are separated so that the displacement plate loses its limit in the inside of the groove. At this time, the displacement plate can be moved. The movement of the displacement plate in the groove drives the slide plate to move on the surface of the slide bar. The movement of the slide plate on the surface of the slide bar drives the first ring to move. The movement of the first ring drives the support arm and the second ring to move. When the second ring moves to a position where it is sleeved on the surface of the connector of the syringe, the bolt is screwed into the corresponding threaded hole again to fix the position of the displacement plate in the groove at this time. Then, the infusion tube is inserted into the And the connector of the syringe, at this time, the first ring and the second ring are used to fix the infusion tube through the middle supporting arm, so that the infusion tube is not easy to bend and remains straight, and then the button on the surface of the shell is used to control the rotation of the first threaded rod, and the rotation of the first threaded rod drives the movable seat to move on the surface of the round rod, and the movement of the movable seat on the surface of the round rod pushes the piston of the syringe to move, so that the medicine inside the syringe is transported into the inside of the infusion tube, and then transported into the patient's body from the inside of the delivery tube to complete the infusion operation.

[0019] 2. In the present invention, by setting an adjustment device, when it is necessary to replace the connector of the syringe, first slide the movable plate to make the movable plate move inside the strip groove. The movement of the movable plate inside the strip groove will squeeze the spring, so that the spring is compressed. At the same time, the movement of the movable plate inside the strip groove also drives the insertion rod to move. The movement of the insertion rod makes it move out from the inside of the socket. The separation of the insertion rod and the socket makes the rotating shaft lose its limit. At this time, the long strip plate can be rotated. The rotation of the long strip plate makes the first ring and the second ring move away from the front of the syringe connector. When the long strip plate is rotated to a suitable angle, the movable plate is released, and the resilience of the spring is used to reinsert the insertion rod into the corresponding socket to re-limit the rotation of the rotating shaft. Through the cooperation of the above structure, the positions of the first ring and the second ring can be changed, thereby avoiding the first ring and the second ring blocking the front of the syringe connector and affecting the replacement operation of the syringe connector.

[0020] 3. In the present invention, by providing an angle adjustment device, when it is necessary to adjust the angle of the shell during specific use, the electric telescopic rod is first started, and the electric telescopic rod is started to drive the movable block to move inside the movable groove, and the movable block moves inside the movable groove to drive the connecting rod to move, and the movement of the connecting rod drives the sliding plate to move inside the long groove, and the movement of the sliding plate inside the long groove drives the rack to move, and the rack moves and engages with the gear, so that the gear rotates, and the rotation of the gear drives the rotating rod to rotate, and the rotation of the rotating rod drives the rotating block to rotate, and the rotation of the rotating block drives the shell to rotate. When the shell rotates to a suitable position, the electric telescopic rod can be closed. Through the cooperation of the above-mentioned structure, the placement angle of the shell can be adjusted accordingly according to the injection angle of the patient, thereby further improving the practicality of the device.

[0021] 4. In the present invention, by setting a lifting device, when the beds in the ward are tight and the patient needs to sit on the chair for infusion, the motor can be started at this time, and the motor starts to drive the second threaded rod to rotate, and the rotation of the second threaded rod drives the sliding plate to move inside the vertical groove, and the movement of the sliding plate inside the vertical groove drives the U-shaped seat to move. The movement of the U-shaped seat drives the push rod to move outward from the inside of the sleeve, and the movement of the U-shaped seat finally drives the shell to move. When the shell moves to a suitable height, the motor can be turned off. Through the cooperation of the above structure, the height position of the shell can be adjusted, so that the device can meet the two situations of patients receiving infusion on the bed or on the chair.

When the connector of the syringe 10 needs to be replaced, first slide the movable plate 32 to move the movable plate 32 inside the strip groove 31. The movement of the movable plate 32 inside the strip groove 31 will squeeze the spring 36, so that the spring 36 is compressed. At the same time, the movement of the movable plate 32 inside the strip groove 31 also drives the insertion rod 33 to move. The movement of the insertion rod 33 makes it move out of the inside of the socket 34. The insertion rod 33 and the socket 34 are separated, so that the rotating shaft 203 loses its limit. At this time, the long strip plate 205 can be rotated, and the long strip plate 205 rotates to make the first ring 209 and the second ring 211 are moved away from the front of the connector of the syringe 10. When the long plate 205 is rotated to a suitable angle, the movable plate 32 is loosened, and the insertion rod 33 is reinserted into the corresponding insertion hole 34 by utilizing the resilience of the spring 36, so as to re-limit the rotation of the rotating shaft 203.

The electric telescopic rod 414 starts to drive the movable block 411 to move inside the movable groove 410. The movable block 411 moves inside the movable groove 410 and drives the connecting rod 412 to move. The connecting rod 412 moves and drives the sliding plate 407 to move inside the long groove 406. The sliding plate 407 moves inside the long groove 406 and drives the rack 408 to move. The rack 408 moves and engages with the gear 409, thereby causing the gear 409 to rotate. The rotation of the gear 409 drives the rotating rod 404 to rotate. The rotation of the rotating rod 404 drives the rotating block 405 to rotate. The rotation of the rotating block 405 drives the shell 1 to rotate. When the shell 1 rotates to a suitable position, the electric telescopic rod 414 can be closed. Through the cooperation of the above-mentioned structure, the placement angle of the shell 1 can be adjusted accordingly according to the injection angle of the patient, thereby further improving the practicality of the device. When there are not enough beds in the ward and the patient needs to sit on the chair for infusion, the motor 53 can be started. The motor 53 starts and drives the second threaded rod 52 to rotate. The rotation of the second threaded rod 52 drives the sliding plate 55 to move inside the vertical groove 54. The sliding plate 55 moves inside the vertical groove 54 and drives the U-shaped seat 403 to move. The movement of the U-shaped seat 403 drives the push rod 402 to move outward from the inside of the sleeve 401. At the same time, the movement of the U-shaped seat 403 eventually drives the shell 1 to move. When the shell 1 moves to a suitable height, the motor 53 can be turned off.
