Description

Technical Field

[0001] The utility model relates to the field of scissors, in particular to a pair of nursing scissors. Background Art

[0002] For existing nursing scissors, when cleaning and nursing a patient's wound, it is necessary to excise external human tissues if necessary, such as cutting gauze, bandages, sutures, trimming hair, nasal hair, fingernails, toenails, human tissues, etc. Sometimes the cutting area is blocked by clothing, gauze, trachea, drainage tube, medical device or other objects, and the cutting space is limited. Different angles need to be used for cutting. Sometimes, for cutting one area, two or even more scissors are required. Therefore, usually medical staff need to be equipped with a variety of different scissors, which not only reduces the efficiency of medical care, but also increases the purchase cost of scissors. The scissors take up a large space and multiple scissors need to be disinfected.

[0003] Chinese Patent Publication No.: CN202933113U, discloses a pair of nursing scissors, including a finger ring, a scissor arm, a connecting shaft and scissor blades. The feature is that a protective plate is provided at the front end of the scissor blades, a rotating shaft is provided on the protective plate, a scissor head is provided on the rotating shaft, and a baffle is provided on the upper section of the protective plate. The structure of this pair of scissors is simple. When the cutting space is limited, this pair of scissors cannot cut at different angles and other scissors need to be replaced for cutting, which not only reduces the efficiency of medical care, but also increases the purchase cost of scissors. The scissors take up a large space and multiple scissors need to be disinfected. Summary of the Utility Model

[0004] Therefore, in view of the above problems, the utility model provides a pair of nursing scissors, which solves the technical problem that it is difficult for scissors to adjust the angle for cutting.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] A pair of nursing scissors, including two rotatably connected scissor parts and a handle connected to the scissor parts. The scissor parts include a blade part, a connecting part and a fixing part which are arranged in sequence from top to bottom. The two connecting parts are rotatably connected through a first rotating part. The handle is rotatably connected to the fixing part through a second rotating part. A plurality of fixing holes are provided on the fixing part, and an elastic ball is provided on the handle. The elastic ball can be inserted into one of the fixing holes for fixation.

[0007] Furthermore:

[0008] An arc-shaped portion protruding outward is provided at the upper end of each of the two connecting portions. A clamping plate is provided on the inner side of one of the arc-shaped portions. A plurality of clamping grooves are provided on the clamping plate. A clamping piece is provided on the other arc-shaped portion. The clamping piece can be bent and deformed. At least one clamping portion is provided on the clamping piece. The clamping portion can be clamped in the clamping groove.

[0009] The surface of the clamping plate where the clamping groove is located is an inclined structure, and the plurality of clamping grooves are inclined downward along the direction of the clamping piece.

[0010] The clamping groove is in a wavy shape, and the clamping portion is in an arc-shaped structure.

[0011] The clamping piece is a spring piece.

[0012] The fixing portion is in an arc-shaped structure, and the radian of the two fixing portions is different.

[0013] One of the fixing portions can extend into the other fixing portion.

[0014] Two through holes are provided on the handle. The through holes are waist-shaped holes. At least two finger grooves are provided on the inner wall of the through holes on the handle.

[0015] Anti-slip grooves are provided on the finger grooves.

[0016] The first rotating member and the second rotating member are rotating shafts.

[0017] By adopting the foregoing technical solutions, the beneficial effects of the utility model are as follows:

[0018] The handle of the utility model is rotatably connected to the fixing part, and the angle between the blade part and the handle is adjustable. When the space is limited, it can cut from different angles without replacing the scissors, greatly improving the cutting efficiency. By pressing the elastic ball, the elastic ball disengages from the fixing hole and is fixed to another fixing hole. This adjustment method is quick and simple. Further, the connecting part has an arc part, which not only makes the scissors beautiful but also strengthens the hardness of the scissors. A clamping piece is arranged inside the arc part, and the clamping piece can be bent and deformed. During the closing process of the scissors, the clamping piece can be bent and deformed, and the clamping part can contact multiple clamping grooves. The clamping grooves give a reverse acting force to the clamping part, thus giving a reverse acting force to the hand. During cutting, it can prevent excessive force and over-cutting, improving the cutting accuracy. When the scissors are not in use, the traditional spring only keeps the two cutting parts in an open state, while the cooperation of the clamping part and the clamping grooves in this solution also has a positioning function when the scissors are not in use, and can keep the two blade parts closed. Further, multiple clamping grooves are inclined downward along the direction of the clamping piece, and the acting force between the clamping part and the clamping grooves gradually increases along the closing direction. Further, the clamping grooves are in a wave shape, and the clamping part is in an arc structure. When they contact, it is smoother and not easy to get stuck. Further, the fixing part is in an arc structure, and the radian of the two fixing parts is different, which can increase the rotation area of the handle. Further, a finger can choose one of the finger grooves to press. Especially when the inclination angle of the handle is large, it is convenient for the fingers of medical staff to press and better perform cutting. Further, the anti-slip groove has an anti-slip function. BRIEF DESCRIPTION OF THE DRAWINGS
