Description

Technical Field

[0001] This utility model relates to the field of scissors technology, specifically to a novel switching structure for scissors. Background Technology

[0002] Scissors are a common household tool. Kitchen scissors are double-edged tools used for cutting meat, vegetables, chicken bones, and other food items in the kitchen. The two blades interlock and can be opened and closed. Later, kitchen scissors were designed to have two separate blades for cutting vegetables or food, making them more convenient. However, existing kitchen scissors lack a locking mechanism, making it impossible to control the opening and closing of the blades according to the user's needs. This poses a risk of accidental hand injury when not in use, resulting in low safety, inconvenience, and a poor user experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0004] This utility model is achieved through the following technical solution:

[0005] A novel switch structure for scissors includes a first scissor blade and a second scissor blade. The middle of the first scissor blade and the middle of the second scissor blade are hinged together by a connecting screw. The first scissor blade and the second scissor blade are detachably connected. A switch mechanism is mounted on the first scissor blade. The switch mechanism includes a switch body mounted on the first scissor blade by a switch screw. One end of the switch body is rotatably connected to the switch screw. A switch torsion spring is sleeved on the outside of the switch screw. One end of the switch torsion spring is connected to the switch screw, and the other end of the switch torsion spring abuts against one end of the switch body. A positioning locking block is provided at one end of the switch body. The second scissor blade is provided with a positioning locking groove corresponding to the positioning locking block.

[0006] Furthermore, a switch cap is installed at the other end of the switch body.

[0007] Furthermore, a switch end cap covering the switch screw is installed at one end of the switch body.

[0008] Furthermore, one end of the switch body is provided with a guide protrusion, and the second shear plate is provided with a guide groove corresponding to the guide protrusion.

[0009] Furthermore, the switch screw is screwed with a lock nut.

[0010] Furthermore, a torsion spring is installed on the inner side of the first and second scissors, with one end of the torsion spring abutting against the first scissor and the other end of the torsion spring abutting against the second scissor.

[0011] Furthermore, both the first and second shear blades are provided with mounting grooves for mounting the torsion spring, and a pressure ring is installed on the inner side of the second shear blade to press one end of the torsion spring.

[0012] Furthermore, the connecting screw is provided with an elongated connecting head, and the second shear plate is provided with an elongated connecting through hole corresponding to the elongated connecting head.

[0013] Furthermore, the connecting screw is screwed with a connecting nut.

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.

[0023] like Figures 1 to 4 The present invention discloses a novel switch structure for scissors, comprising a first scissor blade 1 and a second scissor blade 2. The middle of the first scissor blade 1 and the middle of the second scissor blade 2 are hinged by a connecting screw 3. The first scissor blade 1 and the second scissor blade 2 are detachably connected. A switch mechanism is mounted on the first scissor blade 1. The switch mechanism includes a switch body 5 mounted on the first scissor blade 1 by a switch screw 4. One end of the switch body 5 is rotatably connected to the switch screw 4. A switch torsion spring 6 is sleeved on the outside of the switch screw 4. One end of the switch torsion spring 6 is connected to the switch screw 4, and the other end of the switch torsion spring 6 abuts against one end of the switch body 5. A positioning locking block 7 is provided at one end of the switch body 5, and the second scissor blade 2 is provided with a positioning locking groove 8 corresponding to the positioning locking block 7. One end of the switch body 5 is rotatably connected to the switch screw 4. A switch torsion spring 6 is sleeved on the outside of the switch screw 4. One end of the switch torsion spring 6 is connected to the switch screw 4, and the other end of the switch torsion spring 6 abuts against one end of the switch body 5. One end of the switch body 5 is provided with a positioning lock block 7. The second scissor 2 is provided with a positioning lock groove 8 corresponding to the positioning lock block 7. After the scissors are closed, the positioning lock block 7 is locked in the positioning lock groove 8 to prevent the scissors from opening. At the same time, the opening and closing state of the scissors can be easily controlled according to the user's needs. When not in use, it is not easy to accidentally injure people's hands. It is safe, convenient to use, and provides a good consumer experience.

[0024] A switch cap 9 is installed at the other end of the switch body 5 to facilitate the operation of the switch mechanism.

[0025] One end of the switch body 5 is fitted with a switch end cover 10 that covers the switch screw 4 to prevent the switch mechanism from being affected during operation.

[0026] One end of the switch body 5 is provided with a guide protrusion 11, and the second shear 2 is provided with a guide groove 12 corresponding to the guide protrusion 11, so that the switch body 5 can abut against the second shear 2 and the positioning lock block 7 can smoothly enter or disengage from the positioning lock groove 8.

[0027] The switch screw 4 is screwed with a locking nut 13, making the installation of the switch screw 4 more convenient and stable.

[0028] A torsion spring 14 is installed on the inner side of the first scissor blade 1 and the second scissor blade 2. One end of the torsion spring 14 abuts against the first scissor blade 1, and the other end of the torsion spring 14 abuts against the second scissor blade 2, so that the scissors can open automatically and are easy to use.

[0029] Both the first shear blade 1 and the second shear blade 2 are provided with mounting grooves 15 for mounting the torsion spring 14. The inner side of the second shear blade 2 is equipped with a pressure ring 16 that presses one end of the torsion spring 14, making the torsion spring 14 more stable to install, the spring force release more stable, and the use effect better.

[0030] The connecting screw 3 is provided with a long strip-shaped connector 17, and the second shear 2 is provided with a long strip-shaped connecting through hole 18 corresponding to the long strip-shaped connector 17, which facilitates the disassembly and assembly of the shear 2 and makes it easy to use.

[0031] The connecting screw 3 is screwed with the connecting nut 19, making the installation of the connecting screw 3 more convenient and stable.

[0032] The first scissor blade 1 is connected to the first handle 20, and the second scissor blade 2 is connected to the second handle 21, which facilitates the operation of the scissors and makes them more comfortable to use.

[0033] Usage process:

[0034] 1. When the handle is gripped at a certain distance, the switch mechanism automatically pops open, and the scissors open. Pressing down to a certain distance prevents the scissors from automatically popping open during unpacking or if they fall onto a table / floor, thus improving safety.

[0035] 2. After the switch mechanism is turned on, you can pull the handle with your hand to separate the two scissor blades, which can then be used as knives.

[0036] 3. After the shearing is removed, the switch will automatically reset to the pop-out position.

[0037] 4. By moving the switch mechanism towards the handle, the two scissor blades can be reinstalled and assembled into scissors.

[0038] 5. To lock, push the switch mechanism in the opposite direction of the handle.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
