[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1-4 As shown, a curved shear base includes a U-shaped plate 1. An adjustment component 6 is provided at the middle of the upper end of the U-shaped plate 1. Baffles 9 are installed at the front and rear of the upper end of the U-shaped plate 1. A placement frame 3 is provided at the upper end of the adjustment component 6. A plurality of placement plates 4 arranged in a linear array are movably connected to the left and right inner walls of the placement frame 3. A plurality of placement slots 5 arranged in a linear array are opened at the upper end of the plurality of placement plates 4. The placement slots 5 are used to facilitate the curved shears to be clamped on the placement plates 4. The adjustment component 6 extends to the baffles 9.

[0025] When in use, place the curved scissors on the placement plate 4 through the placement slot 5, with the handle in contact with the bottom wall of the placement frame 3 and the sharp part suspended on the placement plate 4. When the height of the placement frame 3 needs to be adjusted, the overall height of the placement frame 3 and the curved scissors can be stably adjusted by the adjustment component 6, which also makes it convenient for doctors of different heights to place and pick up the curved scissors.

[0026] When the sharp part of the curved scissors is long, it is easy to contact the bottom wall of the placing frame 3. In order to avoid this phenomenon, the height of the placing plate 4 is adjusted by the cooperation of the screw rod 7 and the screw hole 8. The left end and the right end of the placing frame 3 are provided with a plurality of groups of screw holes 8 arranged in a linear array. Each group of screw holes 8 is provided with a plurality of screw holes arranged in a linear array. The screw rod 7 is arranged in the screw hole 8. The screw rod 7 is screwed into the placing plate 4. When the curved part of the curved scissors is long, the screw rod 7 on both sides is rotated to drive the placing plate 4 to move upwards. The screw rod 7 on both sides is inserted into the screw hole 8 at a higher position, and the screw rod 7 is rotated to fix the placing plate 4. The sharp part of the curved scissors can be prevented from contacting the bottom wall of the placing frame 3 and directly contacting the hard surface, which can reduce the wear and damage of the sharp end of the tool and prolong its service life.

[0027] The height of the curved scissors can be adjusted smoothly by the adjusting component 6. The specific structure is that the adjusting component 6 comprises a rotating seat 65. The rotating seat 65 is provided with two and is arranged in a front-rear symmetrical manner. The two rotating seats 65 are installed at the upper middle part of the U-shaped plate 1. The upper end of the two rotating seats 65 is movably connected with a worm wheel 62. The outer surfaces of the two worm wheels 62 are movably connected with a worm gear 61. The worm gear 61 and the worm wheel 62 have self-locking property. The interiors of the two worm wheels 62 are movably connected with a lead screw 64. The front end of the worm gear 61 movably penetrates through the front end of the front side baffle 9 and is fixedly connected with a knob 63. The rear end of the worm gear 61 is movably connected with the front end of the rear side baffle 9. The placing frame 3 is movably connected with the upper ends of the two lead screws 64. The lower ends of the lead screws 64 penetrate through the rotating seat 65 and movably penetrate into the upper wall of the U-shaped plate 1. The rotating seat 65 is a hollow structure and is used for supporting the rotation of the worm wheel 62. When the knob 63 is rotated, the worm gear 61 is rotated, the worm gear 61 drives the two worm wheels 62 to rotate, the two worm wheels 62 drive the two lead screws 64 to move upwards, and the two lead screws 64 drive the placing frame 3 to move upwards stably. Conversely, when the knob 63 is reversely rotated, the placing frame 3 moves downwards stably.

[0028] In order to improve the stability of the placing frame 3 when it is raised, the upper end left middle part and the upper end right middle part of the U-shaped plate 1 are provided with a through hole 10. The interiors of the two through holes 10 are movably sleeved with a guide rod 2. The upper ends of the two guide rods 2 are fixedly connected with the lower end of the placing frame 3. The guide rod 2 is used for guiding the lifting of the placing frame 3.

[0029] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
