Detailed Implementation

[0019] 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.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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. Example 1:

[0021] This embodiment provides a portable paracord cutter, specifically as follows: Figures 1-4 As shown, the device includes a cutting part 11 and a handle. The cutting part 11 is mounted on the handle, which includes a first handle unit 12 and a second handle unit 13. The first handle unit 12 and the second handle unit 13 are detachably connected. It also includes a connecting tube 14, the inner wall of which is provided with a first internal thread and a second internal thread. The cutting part 11 includes a blade holder 113, on which a blade 111 and a blade holder thread 114 are provided. The first handle unit 12 includes a first handle 121, on which a connecting rod 122 is provided, and the connecting rod 122 is provided with a first handle thread 123. The second handle unit 13 includes a second handle 131, on which a second handle thread 132 is provided, and the second handle thread 132 mates with the second internal thread on the connecting tube 14. All non-threaded connections between the above parts are made by riveting.

[0022] Specifically, during use, the user adjusts the handle according to the actual scenario. When a long handle is needed, the first handle thread 123 engages with the first section of the internal thread on the connecting pipe 14. This engagement continues until it can no longer be screwed on, at which point the connection between the first handle unit 12 and the connecting pipe 14 is secure. When a short handle is needed, the tool holder thread 114 engages with the first section of the internal thread on the connecting pipe 14, again rotating until it can no longer be screwed on. At this point, the connection between the cutting part 11 and the second handle unit 13 is secure, and the first handle unit 12 retracts into the second handle 131, entering a standby state. Furthermore, when 121 is inserted into 131, 121 is riveted to 131. Therefore, 14 will be positioned between 131 and 122, meaning that 121 is usually not removable at this point. It can only be removed during maintenance by removing the rivet, thus reducing the risk of parts loss.

[0023] The above settings allow the tool holder to have both long and short states. At the same time, all parts with threads are modular, so when the threads wear out, the corresponding parts can be replaced directly without replacing the whole thing. This reduces maintenance costs and simplifies subsequent repairs. Example 2:

[0024] This embodiment further extends the above embodiment, specifically as follows: Figure 2 As shown, a traction hook 112 is installed on the blade 111. The traction hook 112 is an arc-shaped rod with a smooth transition and a rotating part. The blade 111 and the traction hook 112 are arranged opposite to each other. When the user needs to pull or pull back the paracord before cutting it off, the traction hook 112 can be used to hook and pull the paracord, improving practicality.

[0025] like Figure 3 , Figure 4 As shown, the second tool holder unit 13 also includes a plug 133, which is riveted to the end of the second tool holder 131. Hot melt adhesive is applied between the connecting tube 14 and the thread 132 of the second tool holder. The hot melt adhesive ensures a secure threaded connection between the connecting tube 14 and the second tool holder unit 13, preventing easy loosening; when disassembly is required, the hot melt adhesive at this point can be heated.

[0026] like Figure 1 , Figure 2 As shown, the first handle 121 has anti-slip texture 15 at one end near the connecting rod 122, and both ends of the second handle 131 have anti-slip texture 15. By providing anti-slip texture 15, the user can prevent the knife from slipping or being unable to grip it properly during use.

[0027] The blade 111 and the traction hook 112 are made of a rust-resistant and wear-resistant metal material, while the blade holder 113 and the handle are made of aluminum. Using an aluminum handle can significantly reduce the weight of the knife, making it lighter and easier to carry.

[0028] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
