[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example
[0024] Please refer to Figure 1 As shown, it shows the specific structure of the preferred embodiment of the utility model, which is a multifunctional tool handle rack.
[0025] Among them, the first sawtooth 22 of the upper handle rod 20 can block the saw from being used, and the first magnet 23 can be adsorbed on the handle 42 to prevent the upper handle rod 20 from turning out by itself. The bit 31 of the lower handle rod 30 can be used to tighten screws, and the second magnet 32 can be adsorbed on the handle 42 to prevent the lower handle rod 30 from turning out by itself. After the tool is provided with the multifunctional handle frame, its function is more powerful, and it is also beneficial to improve the connection strength between the handle shell 43 and the handle 42. When the two handle shells 43 and the handle frame are assembled together, the first protrusion 13 can be used for anti-slip; the second protrusion 15 protrudes from the handle shell 43, which can be used specifically for crushing objects and can effectively protect the handle.
[0026] The present application provides a multifunctional knife handle frame, including a knife handle seat 10, and an upper knife handle rod 20 and a lower knife handle rod 30 hinged on the knife handle seat 10; the outer sides of the knife handle seat 10, the upper knife handle rod 20, and the lower knife handle rod 30 are all provided with a first protrusion 13 for anti-slip; the knife handle seat 10 is provided with a first mounting hole 12; the middle part of the knife handle seat 10 has a second obtuse protrusion 15; the upper knife handle rod 20 is provided with a first sawtooth 22 and a first magnet 23 on the inner side; the lower knife handle rod 30 is provided with a second magnet 32 on the inner side, and a screwdriver bit 31 is provided on the free end of the lower knife handle rod 30. The knife handle seat 10, the upper knife handle rod 20, and the lower knife handle rod 30 are accessories made of stainless steel, manganese steel, or high-speed steel, and in this embodiment, stainless steel is preferably used. The first mounting hole 12 is provided with a thread inside, and the first connecting member (screw) assembles the knife handle frame, the handle 42, and the handle shell 43 together. The first protrusion 13 is used to prevent the knife handle from slipping. The obtuse-angled second protrusion 15 in the middle of the handle seat 10 can be specifically used to break objects (such as glass, etc.). In this way, the force point when breaking objects is on the second protrusion 15, and the handle 42 can provide support force to the handle seat 10, so the connection strength of the entire handle is very large, and there is no problem of damage. In addition, the first sawtooth 22 can be used as a saw. The first magnet 23 can be adsorbed on the handle 42 to prevent the upper handle rod 20 from turning out by itself. After the lower handle rod 30 is turned out from the handle shell 43, the screwdriver bit 31 can be used to tighten the screws, and the second magnet 32 can be adsorbed on the handle 42 to prevent the lower handle rod 30 from turning out by itself. When the first sawtooth 22 is worn, only the entire handle frame needs to be replaced, and the maintenance cost is very low. The screwdriver bit 31 is preferably a flat head or a cross head.
[0027] Preferably, the upper handle rod 20 is provided with a first recessed portion 21 on the inner side, and the first serration 22 is provided in the first recessed portion 21. This design is conducive to protecting the first serration 22 and preventing the first serration 22 from being worn after the handle frame, the handle 42, and the grip shell 43 are assembled together. At the same time, both ends of the first recessed portion 21 can be supported on the handle 42, which can give the handle 42 sufficient gripping force.
[0028] Preferably, the free ends of the upper handle rod 20 and the lower handle rod 30 are both provided with buckle holes 14. When the upper handle rod 20 / lower handle rod 30 needs to be turned outward, the upper handle rod 20 / lower handle rod 30 can be easily turned out by buckling the buckle holes 14 with fingernails.
[0029] Preferably, a spring is provided at the hinged position of the upper handle rod 20, the lower handle rod 30 and the handle seat 10. The spring is preferably a torsion spring. The spring is conducive to resetting the upper handle rod 20 / lower handle rod 30, or making it easier to pop out.
[0030] Preferably, at least two second recessed portions 11 are provided on the inner side of the handle seat 10. The second recessed portions 11 correspond to the second protruding portions on the handle 42, and the two are adapted to each other, which is conducive to improving the installation accuracy of the handle 42 and the handle frame, and the assembly is also more convenient. Example
[0031] The present application provides a knife, comprising a multifunctional knife handle frame, a knife body 40, a knife handle 42, and a grip shell 43; the knife body 40 and the knife handle 42 are integrally formed; the knife handle 42 is embedded between the upper knife handle rod 20 and the lower knife handle rod 30; the grip shell 43 wraps the knife handle seat 10, the upper knife handle rod 20, and the lower knife handle rod 30; the first connecting member passes through the grip shell 43 and the first mounting hole 12, and fixes the grip shell 43 to the multifunctional knife handle frame; the anti-slip protrusion protrudes from the grip shell 43; the upper knife handle rod 20 and the lower knife handle rod 30 can be turned out from the grip shell 43. The second protrusion 15 protrudes from the grip shell 43. At least one second connecting member passes through the grip shell 43 and the knife handle 42, and fixes the grip shell 43 and the knife handle 42 together. The back of the knife body 40 is provided with a second serration. The knife body 40 and the knife handle 42 are preferably made of stainless steel to form a whole. The first connecting member is preferably a screw, and the second connecting member is preferably a screw or a latch. During assembly, the handle shell 43 wraps the handle seat 10, the upper handle rod 20, and the lower handle rod 30, and then the first connecting member passes through the handle shell 43 and the first mounting hole 12, and then the second connecting member passes through the handle shell 43 and the handle 42, so that the handle frame and the handle shell 43 are firmly fixed together. More preferably, a fastening ring is provided at the other end of the handle frame, and the fastening ring is sleeved on the handle shell 43, so that the assembly firmness of the handle shell 43, the handle 42, and the handle frame can be further improved. The second protrusion 15 protrudes slightly from the handle shell 43, so that when breaking objects, the handle frame is subjected to force, which is beneficial to protecting the handle. The second sawtooth can be used as a saw or to scrape fish scales, and the usage scenarios are more diverse. The handle 42 can be adsorbed by a magnet.
[0032] In summary, the design focus of the utility model is that when the two handle shells 43 and the handle frame are assembled together, the first protrusion 13 can be used for anti-slip; the second protrusion 15 can be used specifically for crushing objects. After the upper handle rod 20 is flipped out of the handle shell 43, the first serration 22 can be used as a saw. The first magnet 23 can be adsorbed on the handle 42 to prevent the upper handle rod 20 from flipping out by itself. After the lower handle rod 30 is flipped out of the handle shell 43, the screwdriver bit 31 can be used to tighten the screws, and the second magnet 32 can be adsorbed on the handle 42 to prevent the lower handle rod 30 from flipping out by itself. Therefore, after the tool is provided with the multifunctional handle frame, its function is more powerful, and it is also beneficial to improve the connection strength between the handle shell 43 and the handle 42. In addition, if the first serration 22 is worn, the handle frame can be directly replaced, which is very convenient for maintenance.
