[0026] Clamping mechanism includes square clamping block 4 formed by the convexity on sliding block 3, two clamping blocks 4 middle part is provided with the columnar slot for facilitating needle insertion, and "cross" type clamping groove 5 is opened at the slot to insert protruding handle 9, and the columnar part between protruding handle 9 is inserted in the slot, clamping groove 5 corresponds four protruding handles 9, realizes fixed.

[0027] Sliding block 3 is fixedly connected with guide rod 2, fixed together, can be integrally formed.

[0028] As preferred, push-out gap 7 for facilitating needle stalk sliding out forward is arranged between two clamping blocks 4, needle stalk part can slide out forward, is thrown into sharp container, here needs to lift protruding ridge 10, and the front and rear direction of clamping groove 5 can coincide with push-out gap 7 by pushing forward and backward injector.

[0029] Preferably, one of the guide rods 2 has an arc-shaped spring piece 8 extending to the opposite guide rod 2 at its lower end, and the spring piece 8 is directly opposite the needle rod. When the needle rod is pressed against the spring piece 8, the protruding shank 9 is located on the upper side of the clamping groove 5. The spring piece 8 is bent and elastically deformed when pressed down. After being released, the needle rod is pushed back to its original position. Here, the spring piece 8 can be made of plastic and can also be bent upward in an arc.

[0030] The rear ends of the two support blocks 1 are connected by an inverted "U"-shaped clamp 11 that clamps onto the opening of the sharps container. The clamp 11 can be arc-shaped and fits onto the vertical part of the opening of the sharps container. The arc can be set to different sizes to accommodate openings of sharps containers of different diameters. Of course, if it is square, it can also be set to be flat, allowing for flexible application.

[0031] Example 2

[0032] like Figure 5 As shown, a rotary anesthesia syringe needle remover includes two support blocks 1 installed at the opening of the sharps container. A square-section guide rod 2 is connected to the front end of each support block 1. The two guide rods 2 are fixed facing each other in a "V" shape, with a gap between their bottoms. A slider 3 is mounted on each guide rod 2, and a clamping mechanism is mounted on each slider 3 to clamp the protruding shanks around the needle. The upper end of the clamping mechanism abuts against the lower end of an annular protrusion 9 on the upper side of the protruding shank. There are normally four protruding shanks 9, mainly for convenient rotation and unscrewing of the needle. The protruding shanks 9 are fixed to the lower end of the protrusion 10, are hollow inside, and fit over the needle plug. The clamping mechanism abuts against the lower end of the protrusion 10, clamping between the protruding shanks 9. The inner side is threaded for screwing onto a syringe, such as a Bimalan syringe.

[0033] The clamping mechanism includes square clamping blocks 4 formed by the protrusions of the slider 3. Two clamping blocks 4 have cylindrical slots in the middle for easy needle insertion, and the slots have cross-shaped grooves 5 for inserting the protruding shanks 9. The slots facilitate insertion of the cylindrical portions between the protruding shanks 9. The grooves 5 correspond to the four protruding shanks 9 for fixation. The grooves 5 are stepped, corresponding to the protruding shanks. For easier insertion, the upper end of the grooves 5 can be chamfered.

[0034] The slider 3 is sleeved on the guide rod 2 and includes an elastic component for positioning the slider 3, preventing it from wobbling and ensuring the relative positions of the two sliders 3. This allows it to adapt to both larger and smaller sizes, providing greater flexibility. The elastic component is a spring 6 sleeved on the guide rod 2, with both ends of the spring 6 connected to the slider 3 and the support block 1, respectively, for positioning.

[0035] Preferably, a pull-out gap 7 is provided between the two clamping blocks 4 to facilitate the forward sliding of the needle shaft. The needle shaft can slide forward and be dropped into the sharps box. Here, the protrusion 10 needs to be lifted up and the syringe is pushed forward. The front and rear sides of the clamping groove 5 can coincide with the pull-out gap 7.

[0036] Preferably, one of the guide rods 2 has an arc-shaped spring piece 8 extending to the opposite guide rod 2 at its lower end, and the spring piece 8 is directly opposite the needle rod. When the needle rod is pressed against the spring piece 8, the protruding shank 9 is located on the upper side of the clamping groove 5. The spring piece 8 is bent and elastically deformed when pressed down. After being released, the needle rod is pushed back to its original position. Here, the spring piece 8 can be made of plastic and can also be bent upward in an arc.

[0037] The rear ends of the two support blocks 1 are connected by an inverted "U"-shaped clamp 11 that clamps onto the opening of the sharps container. The clamp 11 can be arc-shaped and fits onto the vertical part of the opening of the sharps container. The arc can be set to different sizes to accommodate openings of sharps containers of different diameters. Of course, if it is square, it can also be set to be flat, allowing for flexible application.

[0038] Example 3

[0039] like Figure 6 In contrast to Embodiments 1 and 2, as a preferred embodiment, the clamping plate 11 can also be flat and fitted onto the horizontal opening of the sharps box. Here, both the clamping plate 11 and the support block 1 are horizontally arranged.

[0040] Working principle: The protruding handle 9 is inserted into the clamping groove 5, and the middle part is inserted into the slot. By rotating the syringe, the needle part can be loosened, thus eliminating the need for hand tightening.

[0041] When the needle is inserted, it will squeeze the spring 8. After loosening, the syringe will gradually separate. Under the action of the spring 8, the needle tip will tilt upward and slide out along the pull-out gap 7, falling into the sharps box. It can also be moved by the syringe plunger. It is simple, convenient and safer.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
