Abstract
Description
Technical Field
[0001] This utility model belongs to the field of multi-functional cutting tool technology, and specifically relates to a multi-functional tool knife with quickly replaceable functional parts. Background Technology
[0002] Multi-tool knives generally refer to knives similar to Swiss Army knives. They are typically designed for outdoor survival and temporary use, and mainly feature folding function slots for storage. Both sides are covered with a shell, making them durable and versatile.
[0003] However, the existing multi-tool knife components are installed piece by piece by passing T-nuts through the handle during assembly. Due to the small assembly space, the efficiency is very low. Moreover, it is difficult for consumers to manually disassemble and reassemble after purchase. It is also not conducive to consumers replacing different components according to their own preferences.
[0004] Therefore, it is necessary to design a multi-functional tool knife with quickly replaceable functional parts, so that the multi-functional tool knife can easily and quickly complete the disassembly and replacement actions. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a multi-functional tool knife with quickly replaceable functional parts, including a handle and functional parts. One end of the functional part accommodates a T-shaped pin that forms a rotatable connection with the functional part. The T-shaped pin can be accommodated inside the handle. The upper end of the T-shaped pin is threadedly connected to the handle with an upper screw, and the lower end of the T-shaped pin is threadedly connected to the handle with a lower screw. When it is necessary to disassemble and replace different functional parts of the multi-functional tool knife, first remove the screws at the upper and lower ends of the handle, then take out the T-shaped pin and all functional parts as a whole, then remove the unnecessary functional parts from the T-shaped pin, and then install the necessary functional parts one by one into the T-shaped pin. Finally, insert this as a whole into the narrow space in the middle of the handle. Two screws pass through the upper and lower sides of the handle and lock into the T-shaped pin. The above process can easily and quickly complete the disassembly and replacement actions.
[0006] The technical problem to be solved by this utility model is to provide a multi-functional tool knife with quick-replaceable functional parts, which addresses the shortcomings of the prior art. The tool includes a handle and functional parts. One end of the functional parts is equipped with a T-shaped pin that is rotatably connected to the functional parts. The T-shaped pin can be accommodated inside the handle. The upper end of the T-shaped pin is threaded to the handle with an upper screw, and the lower end of the T-shaped pin is threaded to the handle with a lower screw.
[0007] Preferably, the handle has a hollow structure, and the cavity is used to accommodate the functional component.
[0008] Preferably, the number of the functional components is multiple.
[0009] Preferably, the functional component is composed of multiple blade-shaped pieces.
[0010] Preferably, the upper end of the T-shaped pin is provided with an internal thread.
[0011] Preferably, the lower end of the T-shaped pin is provided with an internal thread.
[0012] Preferably, the lower outer wall of the T-shaped pin is provided with a protrusion, and the handle is provided with a sliding groove that mates with the protrusion. The protrusion can slide into and out of the sliding groove. The protrusion not only ensures that the lowermost functional component is positioned to prevent it from falling off during the process of installing the functional component into the T-shaped pin, but also allows the protrusion to be slid directly into the sliding groove after the functional component is installed, thus improving installation efficiency.
[0013] Preferably, the two sides of the protrusion along the sliding direction are arranged in parallel.
[0014] When using, first remove the upper and lower screws at the top and bottom of the handle, then remove the T-pin and all functional parts as a whole. Next, remove the unnecessary functional parts from the T-pin, and install the necessary functional parts one by one into the T-pin. Finally, install this as a whole into the narrow space in the middle of the handle, and pass the upper and lower screws through the top and bottom sides of the handle and lock them into the T-pin. The above process can easily and quickly complete the disassembly and replacement.
[0015] Compared with the prior art, the positive effects of this utility model are as follows: The multi-functional tool knife with quick-replaceable functional parts in this utility model solves the problem caused by the structural design of the prior art, which requires passing the T-nut through the handle before assembling multiple workpieces. The structure of this utility model adopts the method of first installing the functional parts one by one onto the T-pin, and finally installing it as a whole into the handle. That is, the assembly method of assembling the functional parts first and then assembling the T-pin avoids the defects of the prior art, which requires assembling the T-nut first and then the functional parts, resulting in the assembly of functional parts only inside the handle, small assembly space, and very low efficiency.

[0017] Figure 2 This is a schematic diagram of the assembly structure of the multi-functional tool knife in this utility model;
[0018] The markings in the attached diagram are: 1-Handle 1, 2-Screw, 3-T-nut, 4-Functional component 1, 5-Handle, 6-Upper screw, 7-Lower screw, 8-T-pin, 9-Functional component. Detailed Implementation
[0019] The following is combined with Figure 1-2 The present invention will be further described with reference to specific embodiments.
[0020] See appendix Figure 1 The disclosed diagram is a schematic diagram of the assembly structure of a multi-functional tool knife in the prior art. The multi-functional tool knife includes a handle-1 and a functional component-4. During assembly, after the T-nut 3 passes through the handle-1, the functional components in the functional component-4 are installed one by one onto the T-nut 3. After assembly, the T-nut 3 is threadedly connected to the handle-1 by screws 2. It can be seen that since the assembly space of the functional component is inside the handle-1, the assembly space is small, resulting in very low assembly efficiency.
[0021] To address the aforementioned problems in the existing technology, this utility model conceives of a multi-functional tool knife with quickly replaceable functional components, see attached document. Figure 2 As shown, it includes a handle 5 and a function 9. One end of the function 9 is provided with a T-shaped pin 8 that is rotatably connected to the function 9. The T-shaped pin 8 can be accommodated inside the handle 5. The upper end of the T-shaped pin 8 is threadedly connected to the handle 5 with an upper screw 6, and the lower end of the T-shaped pin 8 is threadedly connected to the handle 5 with a lower screw 7.
[0022] The handle 5 has a hollow structure, and the cavity is used to accommodate the functional component 9.
[0023] The number of the functional components 9 is multiple.
[0024] The functional component 9 is composed of multiple blade-shaped pieces.
[0025] The upper end of the T-shaped pin 8 is provided with an internal thread.
[0026] The lower end of the T-shaped pin 8 is provided with an internal thread.
[0027] The lower outer wall of the T-shaped plug 8 is provided with a protrusion, and the handle 5 is provided with a sliding groove that mates with the protrusion. The protrusion can slide into and out of the sliding groove.
[0028] The two sides of the protrusion along the sliding direction are arranged in parallel.
[0029] When using, first remove the upper screw 6 and lower screw 7 at the top and bottom of the handle 4, then remove the T-shaped pin 8 and all functional parts 9 as a whole. Then remove the unnecessary functional parts 9 from the T-shaped pin 8, and install the necessary functional parts 9 one by one into the T-shaped pin 8. Finally, install this as a whole into the narrow space in the middle of the handle 5, and pass the upper screw 6 and lower screw 7 through the upper and lower sides of the handle 5 respectively, and lock them into the T-shaped pin 8. The above process can easily and quickly complete the disassembly and replacement.
[0030] Compared with the prior art, the positive effects of this utility model are as follows: The multi-functional tool knife with quick-replaceable functional parts in this utility model solves the problem caused by the structural design of the prior art, which requires passing the T-nut through the handle before assembling multiple workpieces. The structure of this utility model adopts the method of first installing the functional parts one by one onto the T-pin, and finally installing it as a whole into the handle. That is, the assembly method of assembling the functional parts first and then assembling the T-pin avoids the defects of the prior art, which requires assembling the T-nut first and then the functional parts, resulting in the assembly of functional parts only inside the handle, small assembly space, and very low efficiency.
[0031] The above description only illustrates the preferred technical solution of this utility model. Any modifications that may be made by those skilled in the art to certain parts of this utility model also reflect the principle of this utility model and should be within the technical scope of this utility model.
