As a product of modern high technology, ceramic knives have the advantages of high hardness, low adhesion, and good red hardness that traditional golden and white ceramic knives cannot match;

[0003] At present, most ceramic blades are usually fixed with fixing structures such as bolts during use. This method will cause the ceramic blade to loosen due to the impact when it contacts the object during the cutting process of the ceramic blade. The bolts are used to fix them, which is inefficient and slow. When the bolts are stripped or rusted, they will be difficult to remove. In view of this, a ceramic blade structure with improved durability is proposed to solve the above problems. Utility Model Content

[0031] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] See also Figure 1-6 , the utility model provides a technical solution: a ceramic blade structure with improved durability, comprising a ceramic blade body 1 and a rotating shaft 4, the ceramic blade body 1 is arranged on the rotating shaft 4;

[0036] A connecting sleeve 2 is fixedly connected to the ceramic blade body 1, and an outer surface of the connecting sleeve 2 is provided with an external thread;

[0037] The connecting sleeve 2 is threadedly connected to a fixed threaded sleeve 3 via an external thread;

[0038] Two auxiliary rotation grooves 6 are provided on the ceramic blade body 1;

[0039] Four telescopic grooves 10 are provided on the surface of the connecting sleeve 2, and the telescopic grooves 10 are arranged on the connecting sleeve 2 in a cross-shaped array;

[0040] A disassembly mechanism is provided inside the telescopic slot 10. When the ceramic blade body 1 is damaged, the disassembly mechanism can quickly disassemble the ceramic blade body 1 from the rotating shaft 4, so that it is convenient to replace it.

[0041] The disassembly and assembly mechanism includes four fixing blocks 9, which are respectively slidably connected to the inside of the telescopic slots 10, and the inner walls of the four telescopic slots 10 are provided with built-in installation slots 13;

[0042] The fixed blocks 9 are all fixedly connected with built-in sliding blocks 11, and the built-in sliding blocks 11 are slidably connected inside the built-in mounting grooves 13;

[0043] A return spring 12 is fixedly connected inside the built-in mounting groove 13, and the other end of the return spring 12 is fixedly connected to the built-in sliding block 11;

[0044] Among them, the ends of the four fixing blocks 9 located outside the connecting sleeve 2 are all inclined surfaces;

[0045] The rotating shaft 4 is provided with a fixed connection groove 16 which is adapted to the four fixed blocks 9;

[0046] One end of the fixed thread sleeve 3 close to the ceramic blade body 1 is a tapered surface 15;

[0047] When installing the ceramic blade body 1 and the rotating shaft 4, first insert the rotating shaft 4 into the interior of the connecting sleeve 2, and align the fixed connecting groove 16 with the fixed block 9. At this time, rotate the fixed threaded sleeve 3, and the fixed threaded sleeve 3 gradually approaches the fixed block 9 by rotating, so that the tapered surface 15 of the fixed threaded sleeve 3 contacts the inclined surface of the fixed block 9. At this time, as the fixed threaded sleeve 3 continues to move, the fixed block 9 is retracted into the interior of the connecting sleeve 2 and stuck into the interior of the fixed connecting groove 16, thereby completing the installation between the ceramic blade body 1 and the rotating shaft 4;

[0048] When it is necessary to remove it, it is only necessary to reversely rotate the fixed threaded sleeve 3. At this time, under the elastic performance of the reset spring 12, the fixed block 9 is no longer squeezed by the fixed threaded sleeve 3 and automatically resets, and disengages from the inside of the fixed connection groove 16;

[0049] At the same time, by setting four fixing blocks 9, it is possible to effectively prevent the rotating shaft 4 from axially shaking when driving the ceramic blade body 1 to rotate, and at the same time prevent it from idling, thereby increasing the service life of the ceramic blade body 1 and reducing the possibility of jamming or axial shaking when it comes into contact with an object.

[0050] Furthermore, the auxiliary rotating groove 6 is rotatably connected with a locking block 5, and the locking block 5 is in a "7" shape;

[0051] An inclined cutout 14 is cut on the transverse plate of the locking block 5, and the inclined cutout 14 makes the transverse plate of the locking block 5 have an inclined surface;

[0052] The locking block 5 is rotatably connected to the positioning shaft 7, and the positioning shaft 7 is fixedly connected to the inside of the auxiliary rotation groove 6;

[0053] A torsion spring 8 is provided on the movable sleeve of the positioning shaft 7, and two torsion arms of the torsion spring 8 are respectively fixedly connected to the positioning shaft 7 and the locking block 5;

[0054] As the fixed threaded sleeve 3 continues to move, the fixed threaded sleeve 3 contacts the surface of the inclined cutout 14 through the tapered surface 15. At this time, as the fixed threaded sleeve 3 continues to move, the locking block 5 is intervened by the fixed threaded sleeve 3 and rotates in the opposite direction. When the fixed threaded sleeve 3 moves to a specified position, the locking block 5 is reset by the elasticity of the torsion spring 8. Therefore, the inside of the cross plate of the locking block 5 conflicts with the plane of the fixed threaded sleeve 3 away from the tapered surface 15, thereby completing the fixation of the fixed threaded sleeve 3 and preventing it from loosening, thereby ensuring the safety of the ceramic blade body 1 during use.

[0055] By providing the inclined cutout 14 , the fixing threaded sleeve 3 can be more smoothly in contact with the locking block 5 , thereby avoiding the mechanical jamming phenomenon.

[0056] Working principle: When installing the ceramic blade body 1 and the rotating shaft 4, first insert the rotating shaft 4 into the interior of the connecting sleeve 2, and align the fixed connecting groove 16 with the fixed block 9. At this time, rotate the fixed threaded sleeve 3, and the fixed threaded sleeve 3 gradually approaches the fixed block 9 through rotation, so that the tapered surface 15 of the fixed threaded sleeve 3 contacts the inclined surface of the fixed block 9. At this time, as the fixed threaded sleeve 3 continues to move, the fixed block 9 is retracted into the interior of the connecting sleeve 2 and stuck into the interior of the fixed connecting groove 16, thereby completing the installation between the ceramic blade body 1 and the rotating shaft 4;

[0057] When it is necessary to remove it, it is only necessary to reversely rotate the fixed threaded sleeve 3. At this time, under the elastic performance of the reset spring 12, the fixed block 9 is no longer squeezed by the fixed threaded sleeve 3 and automatically resets, and disengages from the inside of the fixed connection groove 16.

[0058] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
