The cutting work is carried out.

It is worth noting that the cutting blade 3 and the handle 30 are tightly welded, so that the connection between the cutting blade 3 and the handle 30 is more stable, which facilitates the cutting work.

When the hand-cranked cutting needle sharp tool barrel of this embodiment is in use, first put the needle to be cut into the feeding port 230, place the part to be cut between the two cutting blades 3, and then manually turn clockwise Shake the handle 402 to drive the fixed block 401 and the rotating rod 400 to rotate, thereby driving the first bevel gear 41 to rotate. Driving the threaded rod 42 to rotate can make the two sliders 44 move in the opposite direction of the threaded rod 42 synchronously, thereby driving the two handles 30 to cross and close each other, so that the two cutting blades 3 are closed to each other, so that the needle can be cut off. The needle will fall into the inside, and the friction between the sharps collection bucket 1 and the ground can be increased through the anti-skid pad 10, so that the sharps collection bucket 1 can be placed more stably, which is convenient for the hand cutting work. When it is necessary to cut again , and then turn the crank handle 402 counterclockwise to drive the fixed block 401 and the rotating rod 400 to rotate, so as to drive the first bevel gear 41 to rotate. 43 is rotated, so as to drive the threaded rod 42 to rotate, which can make the two sliders 44 move away from each other on the threaded rod 42 to drive the two handles 30 to cross each other and open each other, thereby making the two cutting blades 3 open to each other, and repeat the above operation. You can continue to cut the needle.
