[0025] The following will combine Figure 1 、 Figure 2 and Figure 3 to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. The components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can also be combined with each other.

[0026] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In the description of the present utility model, the terms "first", "second", "third", and "fourth" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0027] The survival knife described in the present utility model includes a relatively independent knife head 1 and a tubular knife handle, as well as a guard cord 6 fixed to the end of the knife handle.

[0028] To improve the performance of the survival knife and the convenience of carrying. In this example, the tubular knife handle of the survival knife is composed of two sleeves 5 inserted into each other. There are two positioning screws 4 between the bodies of the two sleeves 5. By opening and locking the positioning screws 4, the two sleeves 5 can be telescoped and fastened to each other, achieving the purpose of changing the length of the tubular knife handle and facilitating the use process.

[0029] To achieve a reliable connection between the relatively independent cutter head 1 and the tubular handle, a plug rod 13 is provided on the rear end face of the cutter head 1. The plug rod 13 is inserted into a tubular handle with a matching shape and fixed. At the same time, a transverse baffle 9 is provided on the front end face of the handle. After the cutter head 1 is inserted, the rear end face of the cutter head 1 is supported on the baffle 9, ensuring the reliable support of the handle for the cutter head 1. In this example, to ensure the structural stability during the insertion process, the plug rod 13 is square. The square plug rod 13 is inserted into a square through hole provided on the sleeve 5 and having a shape matching that of the square plug rod 13. At the same time, a positioning pit 11 is provided on the rod body of the square plug rod 13, and a matching fastening screw 8 is provided on the side of the baffle 9 corresponding to the position of the positioning pit 11. Through the mutual cooperation and fastening of the fastening screw 8 and the positioning pit 11, and by using the square through hole to limit the circumferential direction of the plug rod 13, the structural stability during the insertion process of the plug rod 13 is ensured.

[0030] To make the chopping and hacking processes of the cutter head 1 more powerful and endow the cutter head 1 with the function of a shovel. In this example, the shape of the cutter head 1 is trapezoidal. The width of the front end face of the trapezoidal cutter head 1 is greater than that of the rear end face. Cutting edges are provided on the front end face of the cutter head 1 and on one side of the cutter head 1 respectively. The cutting edge on the front end face can form the function of a shovel, while the cutting edge on one side can form the functions of chopping and hacking. Since the width of the front end face of the cutter head 1 is greater than that of the rear end face, good chopping and shoveling effects can be achieved during field use.

[0031] To further enhance the usage functions of the survival knife and endow the survival knife with the function of a hoe. In this example, three positioning connection holes 2 distributed in a triangular shape are further provided on the knife body near the rear end of the cutter head. At the same time, three countersunk head positioning screws 3 that are positionally matched with the positioning connection holes 2 are provided on the baffle 9. When the cutter head 1 is normally connected for chopping, hacking, and shoveling, the three countersunk head positioning screws 3 will not affect the support of the baffle 9 for the rear end face of the cutter head 1. When it is necessary to change the connection method of the cutter head 1 to endow it with the function of a hoe, the plug rod 13 is withdrawn from the sleeve 5, and the countersunk head positioning screws 3 are used to connect with the positioning connection holes 2 on the knife body, so that the cutter head 1 is vertically connected to the handle. Furthermore, the function of a hoe can be formed through the cutting edge on the front end face of the cutter head.

[0032] To further enhance the usage functions of the survival knife. In this example, an ice pick 14 is further provided at the end of the plug rod 13. The length of the ice pick 14 will not affect the insertion process. At the same time, it expands the usage functions of the survival knife in a winter environment and facilitates the field use process.

[0033] To further meet the usage process under field conditions, a tool-type key 7 is provided on the guard rope 6. Through the tool-type key 7, operations such as turning the fastening screw 8, the countersunk head positioning screw 3, and the positioning screw 4 can be performed.

[0034] In actual use, when used as a normal tool, the blade 1 of the survival knife is inserted into the square through-hole of the sleeve 5 through the insertion rod 13, and is fastened to the positioning pit 11 by the horizontal fastening screw 8. The rear end face of the blade 1 is supported on the baffle 9, and normal functions such as chopping, hacking, and shaving can be realized through the blade on one side of the blade body. The connection length of the two sleeves 5 at the handle can be adjusted at any time by using the tool-type key 7, making the chopping process of the survival knife more labor-saving and convenient. When it is necessary to be used as a spade, the blade on the front end face of the blade 1 can be used for shoveling and digging, which is convenient for field use. When it is necessary to be used as a hoe, the connection length of the two sleeves 5 at the handle is adjusted by using the tool-type key 7. At the same time, the insertion rod 13 is removed from the sleeve 5. After the countersunk head positioning screw 3 on the baffle 9 is connected to the positioning connection hole 2 on the blade body, the blade 1 and the handle can form a vertical connection state, completing the conversion of the survival knife into a hoe and meeting the use requirements under different conditions. Of course, the ice pick 14 located on the insertion rod 13 can also meet the use requirements under winter environmental conditions, expanding the use functions of the survival knife.
