The first embodiment is as follows:

referring to fig. 1 to 5, a sharps container with a rotary cutting mechanism comprises a container body 10 and a container cover 20.

The case body 10 is a cylindrical container with an open upper end, and the case cover is installed at the upper end of the case body through a screw.

The box cover is provided with a delivery opening 21 and a shaft hole 27, the delivery opening is an arc opening taking the shaft hole as an arc center, and one end of the delivery opening is a cutting edge 22. The box cover is also provided with a needle pulling opening 25 which is used for pulling out the needle head of the injector and is arranged between the delivery opening 21 and the shaft hole 27.

The inner side of the box cover is provided with a rotary knife rest 30 which is arranged in the box cover in a rotating fit mode, the knife rest is of a rotating arm structure and is provided with a rotating shaft 33, and the rotating shaft 33 is in rotating fit with the shaft hole 27 of the box cover. The knife rest is provided with a knife groove 34, the front end of the knife rest is provided with a knife shaft hole 35, and the side edge of the knife rest is provided with a positioning block 32.

The cutter 40 is mounted on the cutter holder. The cutter is used for cutting on the cutting edge 22 of the box cover until a knife handle 41 and a knife edge 42 are arranged. The cutter is mounted on the cutter frame in a running fit, and the cutter is connected with the cutter shaft hole 35 of the cutter frame through the cutter shaft 43. The shank 41 of the cutting blade extends out of the blade holder.

The torsional spring 31 that the knife rest was equipped with, torsional spring 31 stir the cutting knife, make cutting knife and knife rest locating piece 32 contact, in the sword groove 34 of the knife rest of income.

The rotation stroke of the knife rest is that the knife rest rotates from a position (shown in figure 3) entering the delivery port to a position of a cutting edge, the box cover is provided with a guide groove 24 for controlling the stroke of the knife rest, the guide groove 24 is an arc-shaped groove with a shaft hole 27 as an arc center, the shaft end of the knife shaft 43 extends into the guide groove 24, and the rotation stroke of the knife rest is limited by two top ends of the guide groove 24.

The box cover is provided with a cutter stop 23, when the cutter frame rotates to the cutting direction (R1 direction), when the cutter frame rotates to the distance S =8mm from the cutting edge 22, as shown in the position of figure 5, the cutter handle touches the cutter stop, and the distance S between the cutter frame and the cutting edge is called as the safety distance. The safety distance S may be set to 6mm to 8mm. In this interval, the fingers are unlikely to enter the dispensing opening 21, and it is ensured that the fingers are not accidentally cut by the cutter. The position at this time is referred to as the feed position.

The handle of a knife with after the cutting knife dog touched, the knife rest continued to rotate to the cutting direction, and cutting knife dog 23 stirred the cutting knife and rotated for the knife rest, and the cutting edge 42 of cutting knife stretches out the knife rest and follows through the cutting, realizes the cutting function.

The outer end face of the box cover is provided with a handle 50, the handle is provided with a handle shaft hole 52, and the handle shaft hole 52 is sleeved on the rotating shaft 33 of the knife rest and is fixedly connected with the knife rest through a pin shaft 53. In this embodiment, the handle is oriented parallel to the blade carrier and drives the blade carrier to rotate.

The handle is provided with a sealing plate 51, when the handle rotates to the position of the cutting edge 22, the cutter frame also rotates to the position of the cutting edge 22, the end point of the stroke is reached, the cutter does not rotate any more, the cutting movement of the cutter is completed, and at the position, the sealing plate seals the delivery port 21 and the needle pulling port 25.

The lid is provided with a closure retaining head 26. Due to the action of the torsion spring 31, the knife rest can return to the knife-out position after the cutting operation is completed, in the embodiment, the closed holding head 26 is a permanent magnetic sheet arranged on the end face of the box cover, the handle is provided with a closed contact corresponding to the position of the closed holding head 26, the closed contact is an iron screw, and when the handle drives the knife rest to rotate to the position of the cutting edge, the closed contact is adsorbed by the closed holding head 26, so that the handle is kept at the position, and the closed state of the sharps box is kept.

As shown in fig. 8 to 12, the cutting motion process of the tool post is as follows: in the initial position, the blade carrier and handle are both in a position to enter the delivery port, i.e. outside the delivery port 21, without obstructing the delivery port from the insertion of sharps into the sharps container, as shown in the position of fig. 1 or 3. The handle is moved to rotate towards the cutting direction R1, and the handle drives the tool rest to rotate. The blade holder enters the delivery port with the cutting blade retained in the blade pocket 34 of the blade holder as shown in fig. 8. When the tool post is rotated to the cutting position, the tool shank 41 contacts the cutting edge stop, as shown in fig. 9. After the tool holder has rotated beyond the cutting position, the cutting tool stop toggles the shank 41 of the cutting tool, which rotates on the tool holder, with the cutting edge 42 extending out of the tool holder, as shown in fig. 10. Finally, the handle and the knife rest rotate to the cutting edge 22 of the delivery opening, the cutting knife finishes the cutting operation on the cutting edge, and the handle with the sealing plate completely covers the cutting edge 22, so that the full sealing of the sharps box is realized, and the waste in the sharps box is ensured to be installed and stored, as shown in fig. 11 and 12.

Taking the delivery of an infusion tube with a butterfly needle as an example, the handle is rotated to the initial position, i.e. the position where the knife rest enters the delivery port (as shown in fig. 1 and 3), so that the delivery port is completely opened. A flexible infusion tube 61 with a butterfly needle 60 is fed into the delivery port 21, the handle 50 is rotated, the handle and the knife rest push the flexible tube to move in the direction of the cutting edge 22 (as shown in fig. 6), when the knife rest rotates to pass through the knife outlet position, the cutting knife extends out of the knife rest (as shown in fig. 7), the flexible tube is cut off at the cutting edge 22 of the delivery port 21, and the butterfly needle falls into the barrel 10. In the cutting process, if fingers are accidentally extended into the delivery opening, the handle and the cutter rest cannot be rotated to the cutter outlet position, and the cutting edge of the cutting knife cannot extend out of the cutter rest to hurt the fingers.
