The second clamping spring 513 is fixedly arranged on the inner wall of the second clamping groove 512 and fixedly arranged on the end face of the push column clamping block 506.

[0041] The steps of using this invention are as follows: The syringe is placed inside the first outer casing 201. The syringe handle is inserted into the clamping ring 502, positioned between the push-pin clamping block 506 and the pressure plate 504. The push-pin clamping block 506 can retract within the second clamping groove 512 via the second clamping spring 513, facilitating clamping and fixing of handles of different sizes. During drug extraction, the motor 509 is started, driving the lead screw 510 to rotate. The rotating lead screw 510 drives the pressure plate 511 to slide within the cylinder groove 507 via a thread, allowing the pressure plate 511 to move the clamping ring 502 into the cylinder groove 507 via the connecting rod 503. During this pulling motion, the push-pin clamping block 506 serves as the support structure. After extraction, the motor 509 is stopped. When injection is required, the motor is restarted in reverse. 509. The motor 509 drives the lead screw 510 to reverse and press the pressure plate 511 down inside the cylinder groove 507.

At this time, the supporting force of the push column is the pressure plate 504. The medicine is pushed into the medicine bottle. During the push, the pressure sensor 505 clamps the pressure. When the pressure is detected to be too high, it will notify the motor 509 to stop rotating.

[0042] The steps for using this invention are as follows: Place the syringe into the first outer casing 201; insert the ear plates on both sides of the syringe into the notches 203, positioned between the two side plates 204; insert the syringe plunger into the clamping ring 502; place the plunger handle between the plunger clamping block 506 and the pressure plate 504; and slide the lever 302 to move the half-block... 303 Rotate and align with ring block 301, release lever 302 Telescopic plate 305 Push lever 302 to move half block 303 forms a snap-fit ​​fixation with the ring block 301, and the ring block 301 is fixed to the outer shell, so it can drive the two outer shells to move closer together. The closed two outer shells allow the first bottom block 101 and the second bottom block 102 to fit face to face. At this time, the insert block 106 is inserted into the gripper 104, and the insert block 106 squeezes the gripper block 105. Pressing the clamping block 105 causes it to move backward within the placement groove 110. The clamping block 105 compresses the push spring 109, while the pull rod 113 below the clamping block 105 slides along the traction block 108 to prevent it from sliding down the limiting plate 107. Releasing the pressing force pushes the spring 109, pushing the clamping block 105. This causes the pull rod 113 to enter the latching groove of the traction block 108, thus fixing the clamping block 105. At this time, the gripper 104, which is now inside the placement groove 110, tightly clamps the embedded block 106. Moreover, the push post inside the clamping ring 502 is pushed by the second clamping spring 513 inside the second clamping groove 512, which in turn clamps the push post clamping block 506. Inserting the needle into the medicine bottle and pressing the suction button starts the motor 509, which drives the lead screw 510 to rotate via the belt. The rotating lead screw 510 drives the pressure plate 511 in the cylinder groove 507. The internal movement upwards causes the pressure plate 511 to move into the cylinder groove 507 via the connecting rod 503, pulling the push column and drawing the drug from the vial through the syringe. Pressing the suction motor 509 again stops the motor. This method is then used to draw drugs from multiple vials. When the drug needs to be injected into the main vial, the needle is inserted, and the injection button is pressed, causing the motor 509 to reverse. This reverses the lead screw 510, causing the pressure plate 511 to move downwards within the cylinder groove 507. The pressure plate 504 on the clamping ring 502 presses against the handle, causing the push column to descend and inject the drug. When the pressure sensor 505 experiences pressure exceeding the normal injection pressure, the motor 509 automatically stops rotating to prevent excessive pressure inside the vial.
