Description
Technical Field
[0001] The utility model belongs to the technical field of kitchen knives, and in particular relates to a detachable knife which is easy to clean. Background Art
[0002] Knives are usually used to cut food. Common knives have plastic handles, wooden handles and steel handles. Generally, plastic handles and wooden handles are more commonly used because they are lighter and less expensive. They are also more labor-saving and comfortable to hold. However, plastic handles and wooden handles are prone to rot and mold after a long period of use. Especially in the humid environment of the kitchen, the handles are more likely to rot and mold, which is not conducive to hygiene and service life. Steel handles are not easy to rot, and can be cleaned as new after moldy cleaning. However, steel handles are usually heavier. If the handle is a solid steel handle, the center of gravity of the knife will be moved back, making it more laborious to use and the cost is also higher. But in general, steel-handled knives have a long life, and high-end knives usually use steel handles, with higher added value.
[0003] In order to reduce the weight of the handle, knives with hollow handles or hollow handles have appeared in the existing steel handle knives. The hollow handle is actually a closed hollow handle formed by welding two symmetrical handle pieces. The hollow inside cannot be seen from the outside. The hollow handle is a handle with a hollow hole on the side of the handle. The whole handle is formed in one piece. Whether it is a hollow handle or a hollow handle, its weight is greatly reduced compared to a solid steel handle. For the hollow handle, the welding of the two handle pieces will form welding marks, which will affect the appearance, or the welding is not completely sealed, causing water to enter the handle and mold, and the process is also complicated. The hollow handle is formed in one piece and has good appearance, but the hollow position is easy to accumulate dirt and is difficult to clean, which affects the appearance and hygiene. In addition, the style of the one-piece hollow handle is relatively single, which cannot meet the needs of users well and the user experience is poor. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a detachable knife, which not only makes the knife handle easy to clean, but also allows the style of the knife handle to be flexibly changed.
[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a detachable tool, including a handle and a blade arranged at the front end of the handle, the handle including a main handle and a secondary handle detachably connected to the main handle, wherein the blade is arranged at the front end of the main handle, and the secondary handle is located on the upper side of the main handle, a cavity is enclosed between the secondary handle and the main handle, and the cavity runs through the front and back sides of the handle.
[0006] In the above scheme, the knife handle is formed by splicing the main handle and the auxiliary handle into a hollow structure with a cavity. On the one hand, it reduces the overall weight of the knife handle, making the knife light and comfortable during use; on the other hand, if dirt accumulates in the cavity of the knife handle, the auxiliary handle can be removed from the main handle, and a large opening is formed above the cavity, which makes it convenient to clean the cavity of the knife and keep the knife clean and hygienic; in addition, users can also change the style of the knife by replacing different auxiliary handles according to their needs to better meet their needs.
[0007] Furthermore, in order to facilitate the formation of the hollow structure of the handle and reduce the overall weight of the handle, an arc groove is provided on the upper side of the main handle, and the front and rear ends of the auxiliary handle are respectively detachably connected to the front and rear ends of the arc groove, and a cavity is formed between the arc groove and the inner side of the auxiliary handle. After the auxiliary handle is removed from the main handle, it is more convenient to clean the arc groove.
[0008] Further, the front inner wall of the arc groove is provided with a clamping groove, the front end of the secondary handle is provided with a clamping column matched with the clamping groove; the rear inner wall of the arc groove is provided with a positioning groove, the rear end of the secondary handle is provided with a positioning protrusion matched with the positioning groove, the clamping column at the front end of the secondary handle is buckled with the clamping groove of the front inner wall of the arc groove, the positioning protrusion at the rear end of the secondary handle is placed in the positioning groove of the rear inner wall of the arc groove, and a screw passes through the rear end of the main handle and is threadedly connected with the rear end of the secondary handle. When the secondary handle is installed on the main handle, the clamping column at the front end of the secondary handle is first inserted into the clamping groove of the front inner wall of the arc groove to form a buckle connection, and then the secondary handle is swung clockwise downward so that the positioning protrusion at the rear end of the secondary handle is placed in the positioning groove of the rear inner wall of the arc groove, and then the screw passes through the rear end of the main handle and is threadedly connected with the rear end of the secondary handle, thereby completing the assembly of the secondary handle and the main handle, and the front end of the secondary handle is limited by the clamping column and the clamping groove, and the rear positioning protrusion of the secondary handle is limited by the positioning groove, and after being fixed by the screw, the secondary handle can be firmly fixed on the main handle.
[0009] Furthermore, the card column is tilted downward, which makes it convenient for the card column to be tilted and inserted into the card slot, and at the same time, the card column can be limited in the vertical direction, so that the secondary handle can only be disassembled and assembled in the tilted direction, and the positioning protrusion is vertically downward. After the card column is tilted and inserted into the card slot, the secondary handle is swung clockwise to move closer to the main handle, and the positioning protrusion will automatically cooperate with the positioning slot, and the positioning protrusion is fixed by screws. Therefore, the secondary handle is smooth in the entire assembly process, and there is no forced squeezing of the secondary handle to deform and assemble with the main handle.
[0010] Furthermore, the rear end face of the main handle is a planar structure, and a first screw hole is provided on the rear end face of the main handle, and the first screw hole passes through the groove wall of the positioning groove, and the positioning protrusion is provided with a second screw hole aligned with the first screw hole, and the screw is passed through the first screw hole and the second screw hole. The planar structure of the rear end face of the main handle facilitates the opening of the first screw hole.
[0011] Furthermore, the first screw hole is a countersunk screw hole, and the screw is a countersunk screw that matches the countersunk screw hole. After the screw is tightened, the screw cap is hidden in the screw hole to maintain the beauty of the knife handle.
[0012] Furthermore, arc-shaped grooves are provided on opposite sides of the main handle and the auxiliary handle, and the arc-shaped grooves extend along the length direction of the main handle and the auxiliary handle. The grooves are located in the cavity, which not only does not affect the comfort of holding the handle, but also further reduces the weight of the tool. The arc-shaped grooves are also convenient for cleaning.
[0013] Furthermore, the boundaries between the main handle and the auxiliary handle are smoothly transitioned, so that the outer side of the handle is smooth and comfortable to hold.
[0014] Furthermore, the main handle and the secondary handle are made of different materials. Generally, the main handle is made of the same steel as the blade or a steel material with good welding compatibility with the blade, and the secondary handle can be made of some lightweight metal or non-metal material to reduce the weight of the handle. The secondary handle has a large degree of freedom in material selection and can also improve the appearance of the handle.
[0015] Furthermore, the weight of the main handle is greater than the weight of the secondary handle, so that the center of gravity of the handle is lowered, close to or located at the main handle, making it more comfortable to hold and use.
[0016] Beneficial effects of the utility model:
[0017] 1. The knife handle is a hollow structure with a cavity formed by splicing the main handle and the auxiliary handle. The main handle and the auxiliary handle are made of different materials. Since the auxiliary handle does not need to be connected to the blade, the selection of the auxiliary handle does not need to be limited by the blade. The auxiliary handle has greater freedom in material selection and can easily change the weight of the knife handle. In addition, the auxiliary handle can be made of some materials with color patterns or anti-slip materials. On the premise of reducing the weight of the knife handle, it can also beautify the knife handle or have an anti-slip effect to better meet the needs.
[0018] 2. The main handle and the auxiliary handle are assembled structures. The front ends of the main handle and the auxiliary handle are fixed by snapping the clamping column and the clamping slot, and the rear ends are fixed by the positioning protrusion and the positioning slot with screws. Therefore, the auxiliary handle can be easily disassembled from the main handle. If there is dirt accumulated in the cavity of the handle, the auxiliary handle can be removed from the main handle, which is convenient for cleaning the cavity of the handle and keeping the tool clean and hygienic.
[0019] 3. During the disassembly and assembly of the main handle and the auxiliary handle, the coordination between the clamping column and the clamping slot, and the coordination between the positioning protrusion and the positioning slot only require a sequence. There is no forced extrusion of the auxiliary handle to deform and assemble with the main handle. Therefore, whether the auxiliary handle is made of soft or hard materials, it can be easily assembled with the main handle, which makes the material selection of the auxiliary handle more free.

[0035] The knife handle of this embodiment, the auxiliary handle 12 can be easily disassembled from the main handle 11, so if there is dirt accumulated in the cavity 13 of the knife handle, the auxiliary handle 12 can be removed from the main handle 11, so as to facilitate cleaning of the cavity part of the knife handle and keep the knife clean and hygienic. In addition, the knife handle 1 has a hollow structure and is light in weight, so the knife is light and comfortable during use.
[0036] Example 2
[0037] The present embodiment is embodiment 2 of a detachable tool, which is a further improvement of embodiment 1. The rear end face of the main handle 11 is a planar structure, and a first screw hole 114 is provided on the rear end face of the main handle 11. The first screw hole 114 passes through the groove wall of the positioning groove 113. The planar structure of the rear end face of the main handle 11 facilitates the opening of the first screw hole, and the positioning protrusion 122 is provided with a second screw hole 123 aligned with the first screw hole 114, and the screw 3 is passed through the first screw hole 114 and the second screw hole 123.
[0038] As an improvement to the present embodiment, in order to maintain the beauty of the knife handle, the first screw hole 114 is a countersunk screw hole, and the screw 3 is a countersunk screw that matches the countersunk screw hole. After the screw 3 is tightened, the screw cap is hidden in the screw hole, thereby maintaining the beauty of the knife handle.
[0039] As an improvement to the present embodiment, arc-shaped grooves 4 are provided on opposite sides of the main handle 11 and the auxiliary handle 12. The arc-shaped grooves 4 extend along the length direction of the main handle 11 and the auxiliary handle 12. The grooves 4 are located in the cavity 13.

[0040] Preferably, the boundary between the main handle 11 and the auxiliary handle 12 at the joint is a smooth transition, which is equivalent to the main handle 11 and the auxiliary handle 12 being flush at the joint, so that the outer side of the handle is a smooth surface and comfortable to hold.
[0041] Although the knife handle of the present embodiment is not integrally formed, after the main handle 11 and the auxiliary handle 12 are assembled, the structure is stable and compact, and the appearance is smooth, which does not affect the comfort of holding the knife handle and the reliability of the structure.
[0042] Example 3
[0043] This embodiment is Embodiment 3 of a detachable tool, which is a further improvement of Embodiment 2. The main handle 11 and the secondary handle 12 are made of different materials.
[0044] As an improvement to the present embodiment, the main handle 11 is made of the same steel as the blade 2 or is made of steel with good welding compatibility with the blade 2, thereby ensuring the reliability of the connection between the main handle 11 and the blade 2, and the secondary handle 12 can be made of some lightweight metal or non-metal material, thereby further reducing the weight of the handle and making the weight of the main handle 11 greater than that of the secondary handle 12, thereby making the center of gravity of the handle 1 lower, close to or located at the main handle 11, making it more comfortable to hold and use.
[0045] Since the auxiliary handle 12 does not need to be connected to the blade 2, the material selection of the auxiliary handle 12 does not need to be limited to the material of the blade 2. The auxiliary handle 12 has greater freedom in material selection. For example, the auxiliary handle 12 can be made of some materials with color patterns or anti-slip properties. While reducing the weight of the handle, it can also beautify the handle or have an anti-slip effect to better meet the needs.
[0046] The knife of this embodiment, because the main handle 11 and the auxiliary handle 12 are separate structures, and the material selection of the auxiliary handle 12 is free, the auxiliary handle 12 can be customized according to the needs. For example, in order to make the knife handle have good anti-slip properties, the auxiliary handle 12 can be made of plastic, wood and other materials with high anti-slip properties; for example, in order to make the knife handle more beautiful, the auxiliary handle 12 can be made of materials with color patterns. Alternatively, the knife can be freely assembled in a personalized way. Only one main handle 11 and blade 2 combination is required, and multiple different auxiliary handles 12 are matched. In this way, the user can freely match the auxiliary handle 12 with the main handle 11, which increases the user experience and can also realize the recycling of components to avoid waste.
