Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a pair of retractable scissors. Background Art

[0002] During clinical care or infusion treatment, scissors are needed to cut medical devices. For example, after the infusion is completed, scissors are needed to cut the infusion needle and the infusion tube so that the infusion needle can be placed separately in a sharps box for classification and collection. Therefore, scissors are usually placed on the treatment cart.

[0003] The existing treatment cart is not equipped with a structure specifically for placing scissors, so the scissors can only be placed in a storage box on the treatment cart, and the scissors can be taken out when in use. The scissors are placed randomly and are prone to being lost. There is also a possibility of accidental injury. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-4 The utility model provides a retractable scissors, including a key chain 1, a winding box 2, a folding metal scissors 3, a first connecting rope 4 and a second connecting rope 5. A winding mechanism 6 is provided in the winding box 2, and a pair of telescopic openings are symmetrically provided on the winding box 2. One end of the first connecting rope 4 is wound on the winding mechanism 6, and the other end passes through one of the telescopic openings and extends to the outside of the winding box 2 and is fixedly connected to the key chain 1. One end of the second connecting rope 5 is wound on the winding mechanism 6, and the other end passes through the other telescopic opening and extends to the outside of the winding box 2 and is fixedly connected to the handle of the folding metal scissors 3. The winding mechanism 6 is used to adjust the winding and release of the first connecting rope 4 and the second connecting rope 5. The structural layout, construction and working principle of the folding metal scissors 3 are consistent with the foldable scissors in the prior art, and the prior art is adopted, and the details are not repeated in this application.

[0022] When the device is in use, the key chain 1 is mounted on the handle of the treatment cart. When the scissors need to be used, the first connecting rope 4 and the second connecting rope 5 are lengthened, and the reeling mechanism 6 releases the first connecting rope 4 and the second connecting rope 5, so that the overall extension length of the first connecting rope 4 and the second connecting rope 5 is close to 100 cm, thereby facilitating the long-distance use of the folding metal scissors 3. After the scissors are used, the reeling mechanism 6 is used to automatically retract the first connecting rope 4 and the second connecting rope 5 and fold the folding metal scissors 3 to achieve the folding and storage of the folding metal scissors 3, thereby avoiding the folding metal scissors 3 from being lost due to being placed randomly or accidentally touched and hurting people.

[0023] Specifically, the winding mechanism 6 includes a winding rod 61, a spiral spring 62 and a spacer 63. Mounting holes 201 are respectively provided on both sides of the winding box 2. The winding rod 61 is rotatably mounted in the winding box 2, and both ends are respectively inserted into the mounting holes 201. Both ends of the winding rod 61 are sleeved with a spiral spring 62. One end of the spiral spring 62 is fixed to the winding rod 61, and the other end is fixed to the inner wall of the mounting hole 201. The spacer 63 is fixed to the winding rod 61. The first connecting rope 4 is wound on the winding box 2. The second connecting rope 5 is wound on the winding rod 61 and is located on one side of the partition plate 63. When the first connecting rope 4 and the second connecting rope 5 are pulled to extend, the winding rod 61 is driven to rotate. The rotating winding rod 61 causes the partition plates 63 on both sides to elastically store energy. After the folding metal scissors 3 are used, the elastic reset effect of the partition plate 63 can be used to drive the winding rod 61 to rotate automatically, thereby realizing the rotation and winding of the first connecting rope 4 and the second connecting rope 5.

[0024] In addition, the first connecting rope 4 and the second connecting rope 5 are wound on the winding rod 61 on both sides of the partition plate 63, and the partition plate 63 separates the first connecting rope 4 and the second connecting rope 5 to avoid mutual interference and entanglement during winding.

[0025] Specifically, one end of the winding rod 61 extends through to the outside of the winding box 2, and a clamping mechanism 8 is provided on the outer surface of the winding box 2 for clamping and limiting the end of the winding rod 61 extended to the outside. When the first connecting rope 4 and the second connecting rope 5 are released and extended, the outer end of the winding rod 61 is clamped and limited by operating the clamping mechanism 8, which can prevent the winding rod 61 from rotating and resetting under the elastic action of the spiral spring 62 to rewind the first connecting rope 4 and the second connecting rope 5, which helps to maintain the extended length of the first connecting rope 4 and the second connecting rope 5. In addition, when the folding metal scissors 3 are retracted and reset after use, the outer end of the winding rod 61 is clamped and limited by operating the clamping mechanism 8, which can prevent the first connecting rope 4 and the second connecting rope 5 from stretching and contracting at will, thereby ensuring the stability of the folding metal scissors 3 when stored.

[0026] The cam 82 is then engaged with the drawbar 81 and the drawbar 82 is engaged with the drawbar 81, and the drawbar 82 is engaged with the drawbar 81.

[0027] Specifically, a storage box 7 is fixed on the outer surface of the winding box 2, and the storage box 7 is used to store the folding metal scissors 3. A first magnet block 71 for magnetically fixing the scissors is fixed on the inner wall of the storage box 7. When idle, the folding metal scissors 3 can be stored on one side of the winding box 2 by placing the folding metal scissors 3 into the storage box 7 and magnetically fixing them with the first magnet block 71.

[0028] Specifically, a second magnet block 72 is fixed on the outer surface of the storage box 7, and the second magnet block 72 is used to magnetically fix the storage box 7 and the winding box 2 as a whole to the metal part of the treatment cart. The storage box 7 and the winding box 2 are magnetically fixed as a whole to the metal part of the treatment cart using the second magnet block 72, so that the storage box 7 and the winding box 2 as a whole can be prevented from shaking freely when stored, thereby effectively ensuring the stability of the folding metal scissors 3 when stored.

[0029] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and the performance or use are the same, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
