[0051] During use, first place the syringe in the clamp 2 on the support frame 1 and fix it; if boosting operation needs to be performed on a certain syringe, rotate the corresponding knob 10, the knob 10 drives the screw rod to rotate, and then pushes the sliding block 9 to slide inside the support frame 1; the convex block of the sliding block 9 cooperates with the groove 601 on the sleeve 6 and the threaded ring block 8, driving the threaded ring block 8 to move, so that the threaded ring block 8 contacts the sleeve 6; at this time, the clamping rod 11 is inserted into the fixing hole 501 on the driven gear 5 under the action of external pressure.

[0053] In summary, compared with the prior art, the following beneficial effects are achieved: Through the cooperation of structures such as the active rod, active gear, transmission rod, auxiliary gear, driven gear, sleeve, threaded ring block, threaded rod, and extrusion plate, the electric boost of the needle filter is realized, replacing manual operation, greatly improving the operation efficiency, and reducing finger fatigue. At the same time, when a certain threaded rod is not in use, it can prevent the driven gear from driving the sleeve to rotate, ensuring that the threaded ring block can accurately dock with the sleeve during subsequent use, improving the reliability and convenience of the device. The design of the fixing hole, clamping rod, and spring makes the connection and separation between the sleeve and the driven gear more flexible. The limiting rod defines the rotation trajectory of the threaded rod, ensuring that it can only move up and down. The cooperation of the connecting block, connecting rod, and sliding groove not only realizes the connection between the sleeve and the threaded ring block but also stabilizes the position of the threaded ring block when not in use, ensuring the normal operation of the device.
