Description

Technical Field

[0001] The utility model relates to the technical field of knives, and more specifically to a safe and portable mini ceramic knife. Background Art

[0002] A ceramic knife is a type of knife, which usually consists of a handle, a blade and a scabbard. When the blade is not in use, it is often inserted in the scabbard to hide its sharp edge. When in use, the blade can be pulled directly out of the scabbard, making it very convenient to carry.

[0003] Based on the above, the inventors found that the blades of existing ceramic knives are usually processed to be thinner and sharper. When cutting some items such as fruits, although the cutting is more convenient and smooth, the sharp blade is particularly easy to hurt the hands, and the operational safety cannot be improved. It is easy to cause cuts during use. Therefore, in view of this, the existing structure is studied and improved to provide a safe and portable mini ceramic knife, in order to achieve the purpose of having more practical value.

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0032] Example:

[0033] See also Figure 1-4 A safe and portable mini ceramic knife comprises a handle 1, a blade 2 and a scabbard 3. The handle 1 rotates at one end of the scabbard 3, the blade 2 is arranged inside the scabbard 3, a knife seat 4 is slidably connected inside the scabbard 3, and the knife seat 4 is fixedly connected to one end of the blade 2. Guide holes 5 are opened on both sides of the scabbard 3, and limited stoppers 6 are fixedly connected on both sides of the knife seat 4. The limited stoppers 6 extend to the outside of the scabbard 3, and the outer periphery is slidably connected to the side wall of the corresponding guide hole 5. The blade 2 is a double-edge structure, and the upper edge of the blade 2 is fixedly connected to the lower edge of the knife seat 4. The cutting edge and the lower cutting edge are both arranged to be serrated, and the end of the blade 2 away from the blade seat 4 is arranged to be an R chamfered structure. When in use, the upper and lower edges of the blade 2 are first sharpened, and then the upper and lower cutting edges are ground into a serrated shape. This can not only prevent the blade 2 from being too sharp, but also ensure that it is safer when used. At the same time, the end of the blade 2 away from the blade seat 4 is arranged to be an R chamfered structure, making its end smoother, effectively avoiding the phenomenon of stabbing the user's hand during use, and further improving its safety of use.

[0034] See also Figure 2 The knife handle 1 is integrally injection-molded by a rotating part 101 and a clamping part 102 . The rotating part 101 is clamped on one end of the scabbard 3 , and the inner walls on both sides are rotatably connected to the outer periphery of the scabbard 3 . The clamping part 102 is clamped on the top of the scabbard 3 .

[0035] See also Figure 2A first card slot 103 , a second card slot 104 and a third card slot 105 are provided on both sides of the clamping portion 102 , and the first card slot 103 is engaged with the corresponding limit stopper 6 .

[0036] See also Figure 2 The other end of the scabbard 3 is provided with protrusions 7 on both sides, and the inner side wall of the clamping portion 102 is provided with a groove 8 at a position corresponding to the protrusion 7, and the protrusion 7 is clamped and connected with the corresponding groove 8.

[0037] See also Figure 1 The other end of the scabbard 3 is provided with a knife outlet 9.

[0038] See also Figure 3 A gap is set between the upper and lower cutting edges of the blade 2 and the inner wall of the scabbard 3. By setting the gap, the upper and lower cutting edges of the blade 2 can be protected to avoid wear caused by friction with the inner wall of the scabbard 3.

[0039] During use: when the knife needs to be taken out, the rotating part 101 is rotated so that the clamping part 102 can be rotated upward and separated from the top of the scabbard 3. At this time, the limit block 6 on the knife seat 4 is separated from the clamping groove 103. At this time, the knife seat 4 is pushed so that the blade 2 extends from the knife outlet 9. When the limit block 6 moves to the other end of the guide hole 5, the handle 1 is reset, and the limit block 6 is clamped by the clamping groove 3 105 to ensure the stability of the blade 2. At this time, the radish knife can be used to cut objects such as fruits. At the same time, the blade 2 is set to a double-edge structure, and the upper and lower edges are both set to a serrated shape, and the end away from the knife seat 4 is set to an R chamfered structure, which makes the operation convenient and improves its safety while avoiding hand injuries.
