AI Technical Summary
Existing adjustable-cutting-angle kitchen scissors are prone to slight displacement at the connection between the screw and the blade during use, which affects the normal use of the knife.
By adding a transparent ring plate, a graduated retaining ring, a clamping ring, a square groove, a slider, a traction slide plate, a guide rod, a first spring, a notch, a second spring, and an anti-slip post to the connection end of the fixing screw, the lateral load of the scissors during the cutting process is limited, and displacement at the connection between the screw and the blade is prevented.
It effectively reduces the minute displacement at the connection between the screw and the blade during the cutting process, ensuring the normal use and stability of the scissors.

Technical Field
[0001] This utility model relates to the field of kitchen scissors technology, specifically to a kitchen scissors with an adjustable cutting angle. Background Technology
[0002] In daily life, kitchen scissors are a double-edged tool designed specifically for the kitchen. They are mainly used for processing food. The overall design features two intersecting blades, and the two blades are connected by a central screw. When opened and closed, they generate shearing force, which can quickly cut food. They are multifunctional, efficient, and safe. However, when using kitchen scissors, you should avoid tilting them to prevent accidental hand injuries.
[0003] Currently available kitchen scissors with adjustable cutting angles mostly adjust the tightness and cutting angle by adjusting the tension of the fixing screw at the blade connection. However, without anti-loosening protection, the lateral load generated during cutting may accelerate the loosening of the scissors, causing slight displacement at the screw-blade connection and affecting the normal use of the scissors. Therefore, this paper proposes a kitchen scissor with an adjustable cutting angle to address the above problems. Utility Model Content

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution:
[0020] An adjustable cutting angle kitchen scissors includes a first blade 1, a second blade 2 located behind the first blade 1, a limiting groove 3 on the front end face of the first blade 1, a fixing screw 4 passing through the central hole inside the limiting groove 3, a viewing ring plate 5 sleeved on the front end of the fixing screw 4, a graduated retaining ring 6 threadedly connected to the inner surface of the limiting groove 3 on the outside of the viewing ring plate 5, square grooves 8 on both the upper and lower ends of the end face of the graduated retaining ring 6 near the limiting groove 3, a slider 9 slidably connected to the inner side of the square groove 8, a traction slide plate 10 fixedly connected to the rear end of the slider 9, a clamping ring 7 fixedly connected to the bottom of the traction slide plate 10, an anti-slip post 16 fixedly connected to the inner surface of the clamping ring 7, a guide rod 11 slidably connected to the center of the slider 9, and a first spring 12 and a second spring 14 respectively sleeved on the upper and lower ends of the guide rod 11.
[0021] like Figure 1 As shown, the second blade 2 and the fixing bolt are connected through each other. The bottom of both the second blade 2 and the first blade 1 are fixedly connected with inserts 17. The second blade 2 and the first blade 1 are arranged in an alternating pattern. This structure facilitates the normal opening and closing of the kitchen scissors. The bottom of the insert 17 is fixedly connected with a plastic handle 18. The inner surface of the groove in the middle of the plastic handle 18 is provided with anti-slip protrusions 19. The two rows of anti-slip protrusions 19 are arranged at an angle and equidistant. The anti-slip protrusions 19 can increase the anti-slip effect when using the kitchen scissors.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the viewing ring plate 5 and the limiting slot 3 are coaxially arranged, and the viewing ring plate 5 and the clamping ring 7 are arranged in opposite positions. The arrangement of the viewing ring plate 5 facilitates the operator's observation of whether the upper and lower clamping rings 7 are clamping the fixing screw 4. There are two clamping rings 7 in total. The anti-slip post 16 is fitted to the outer surface of the fixing screw 4. An adjustment slot 15 is opened in the middle of the fixing screw 4. The traction slide plate 10 and the graduated retaining ring 6 are slidably connected together. The guide rod 11 is fixedly installed inside the square groove 8. One end of the first spring 12 and the second spring 14 are respectively The first spring 12 and the second spring 14 are fixedly connected to the inner surface of the square groove 8. The other ends of the first spring 12 and the second spring 14 are fixedly connected to the slider 9 respectively. The surface of the traction slide plate 10 is provided with a notch 13. The arc-shaped end of the traction slide plate 10 extends into the guide groove extending outside the limiting hole groove 3. The reserved setting of the guide groove extending outside the limiting hole groove 3 is conducive to the operator to easily unscrew the anti-loosening limiting structure by pushing the traction slide plate 10 inward. The scale line provided on the outer surface of the scale ring 6 is conducive to the operator to observe the loosening angle of the fixing screw 4.
[0023] Workflow: When assembling the kitchen scissors, first screw the graduated retaining ring 6 into the limiting slot 3. Once screwed in place, the traction slide 10 will precisely extend into the guide groove provided on the outside of the limiting slot 3. Then, with the first blade 1 and the first blade 1 hole interlocked, align the inside of the limiting slot 3 and insert the fixing screw 4 to compress and limit the upper and lower retaining rings 7. The interlocked first blade 1 and second blade 2 are connected together by the fixing screw 4. Finally, attach the screw cap to the rear end of the fixing screw 4 to limit it, forming a rotation fulcrum so that the kitchen scissors can then cut. While cutting and opening, under the connection and limitation of the square groove 8 and the guide rod 11, the first spring 12 and the second spring 14 begin to release and rebound. The slider 9 will achieve reset and rebound by pulling the sliding plate 10 and the clamping ring 7. The upper and lower clamping rings 7 will be well fixed by the multiple anti-slip posts 16 provided on the inner ring surface to prevent the fixing screw 4 from slipping and protect it from loosening. When using the kitchen scissors, the operator can hold the plastic handle 18 with two fingers at the same time to adjust the opening and closing angle and cutting angle of the first blade 1 and the second blade 2 by using the rotation fulcrum formed after the fixing screw 4 is installed, so as to cut food of different thicknesses.
[0024] 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.
