[0007] In order to provide power to the automatic shearing mechanism, as an induction-type automatic needle shearing device preferred in the present invention, a servo is installed on the upper end surface of the mounting plate, and the output end of the servo is fixedly connected to the turntable.

[0008] In order to facilitate the guidance of the infusion needle, an induction-type automatic needle cutting device is preferably used in the present invention. A connecting plate is fixedly connected to the upper outer wall of the vertical plate, and a guide port is fixedly connected to the other end of the connecting plate. The guide port is located directly above the two cutters, and a photoelectric sensor is installed on the inner side wall of the guide port. A sealing cover is movably connected to the top of the guide port.

[0009] In order to facilitate voice reminders and control of the automatic cutting mechanism, an induction-type automatic needle cutting device is preferably used in the present invention.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] When the sharp tip needs to be cut, the sealing cover is opened and the sharp tip is extended into the guide port. When the sharp tip passes the photoelectric sensor, the photoelectric sensor transmits a signal to the single-chip microcomputer. The single-chip microcomputer receives the signal and controls the voice broadcast board to issue a voice prompt, such as: "Be careful, avoid needlestick injuries." Each voice reminder is broadcast twice, so as to remind medical staff in time to avoid needlestick injuries.

[0013] The servo drives the turntable to rotate 360 ​​degrees, and the movable shaft performs a complete push-pull action, thereby driving the push-pull parts to push and pull. When the guide rod is pulled backward inside the guide groove, the two shears are driven to open to both sides. When the guide rod is pushed forward inside the guide groove, the two shears are re-closed to each other and closed, thereby realizing a unit shearing action. Therefore, the sharp heads can be automatically sheared, and the sheared sharp heads fall into the sharps box for collection, realizing automatic shearing with a high degree of automation. No manual operation is required for shearing, which effectively avoids needle stick injuries and has high safety. BRIEF DESCRIPTION OF THE DRAWINGS
