[0022] 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.

[0023] like Figures 1 to 4 As shown, this utility model provides a multifunctional folding scissor dagger, including a handle 1. There are four handles 1, with limit posts 9 installed on the inner surfaces of two of them. Each pair of handles 1 forms a group. The inner surface of one group of handles 1 is rotatably connected to a main scissor component 1 2 via a connecting pin, and the inner surface of the other group of handles 1 is rotatably connected to a main scissor component 2 3 via a connecting pin. A scissor connecting pin 4 is rotatably connected to the inner surface of the main scissor component 1 2. One end of the main scissor component 2 3 has a locking groove 44 for use with the scissor connecting pin 4. An internal spring 41 is wound around the outer surface of the scissor connecting pin 4. The connection between the main scissor component 1 2 and the main scissor component 2 3 is achieved through the engagement of the scissor connecting pin 4 with the locking groove 44 of the main scissor component 2 3, providing the core structure for the scissor function. The internal spring 41 continuously applies elastic force, effectively preventing the scissor connecting pin 4 from loosening and ensuring structural stability during cutting. Combined with the rotating design of the two groups of handles 1, this design not only ensures stable operation of the scissor function but also allows for safe storage by rotating the handles 1, keeping the blade in a safe space and improving portability and safety.

[0024] Specifically, the end of the main scissor component 3 furthest from the handle 1 is shaped like a sharp blade. The side of the sharp blade end of the main scissor component 3 is provided with a sharp cutting edge adapted to the function of a dagger, so that the main scissor component 3 also has the cutting function of a dagger. This allows the device to meet the user's need for a sharp cutting tool while having a cutting function, thus expanding the applicable scenarios of the device.

[0025] like Figures 1 to 4 As shown, a spring groove washer 42 is fitted onto the outer surface of the scissor connector 4. The spring groove washer 42 abuts against the built-in spring 41. The spring groove washer 42 can position and limit the built-in spring 41, preventing the built-in spring 41 from shifting or falling off during operation, ensuring the stable elasticity of the built-in spring 41, and reducing direct friction between the built-in spring 41 and other components, thus extending the service life of the built-in spring 41.

[0026] Furthermore, the inner surfaces of both sets of handles 1 are fixedly connected with a back bone 6, and the inner surfaces of both sets of handles 1 are installed with fixing screws 7. The inner surfaces of both sets of handles 1 are also fixedly connected with a liner 5 by fixing screws 7. The back bone 6 can enhance the structural strength of the handle 1 and improve the overall stability of the device. The liner 5 is firmly connected to the handle 1 by fixing screws 7, which can support and protect the relevant components and reduce the wear of the handle 1.

[0027] like Figures 1 to 4 As shown, positioning grooves 43 are provided at one end of the two lining pieces 5, the first main scissor piece 2, and the second main scissor piece 3. Steel balls 51 are provided on the inner surface of the positioning grooves 43 on the two lining pieces 5. The cooperation between the positioning grooves 43 and the steel balls 51 can guide and position the parts when they rotate relative to each other. At the same time, the steel balls 51 can reduce the frictional resistance between the parts, making the rotation more flexible and smooth, and improving the operating feel.

[0028] It is worth noting that one end of one of the handles 1 is rotatably connected to a latch 8. The latch 8 can lock the device when it is not in use to prevent the parts from being accidentally unfolded, ensuring safety during carrying and storage, and also maintaining structural stability when using specific functions.

[0029] Working principle and process: When using the scissors function, rotate the two sets of handles 1 to drive the main scissors 1 2 and main scissors 2 3 to unfold from the stored state. At this time, the scissors connecting pin 4 on the main scissors 1 2 is embedded in the locking groove 44 of the main scissors 2 3. The built-in spring 41 continuously applies elastic force to make the two lock tightly. The opening and closing of the handles 1 drives the blades of the two main scissors to cross and achieve cutting. The spring groove washer 42 ensures that the elastic force of the built-in spring 41 is stable.

[0030] When switching to the dagger function, rotate the scissor connecting pin 4 to disengage it from the locking groove 44 of the main scissor part 2 3, thereby releasing the linkage between the two. Then, retract the main scissor part 1 2 so that it fits against the corresponding handle 1. The pointed end and sharp edge of the main scissor part 2 3 unfold separately, and the limiting post 9 restricts its rotation angle to maintain a stable dagger shape.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] 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.
