[0023] Example 1

[0024] like Figures 1-5 As shown, the present invention proposes a kitchen knife, including a blade 1, a handle 3, a screw 8, and a drive assembly. The cutting surface of the blade 1 is provided with an arc-shaped blade edge 101. The blade edge 101 and the blade body are smoothly connected, and the back of the blade 1 is provided with serrations 102. The handle core 2 is integrally connected to the blade 1. The handle 3 is provided with a slider 5 that is slidably connected to it. The handle core 2 is inserted into the handle 3 and connected to the slider 5. A screw nut 7 is provided on the slider 5. The handle 3 includes a lower cover 31 and an upper cover 32. The lower cover 31 and the upper cover 32 are connected by fasteners, including but not limited to rivets 4, and there are multiple rivets 4. The lower cover 31 is provided with a sliding groove 311 and a positioning groove 312 communicating with the sliding groove 311. The slider 5 is located in the sliding groove 311 and fits against its inner wall. The slider 5 is a non-cylindrical structure. A limiting groove 501 is provided on the side of the slider 5 near the entrance of the positioning groove 312. The handle core 2 passes through the positioning groove 312 and is inserted into the limiting groove 501. A countersunk hole 502 is provided on the slider 5. A bolt 6 that is threadedly connected to the slider 5 is provided in the countersunk hole 502. A through hole A201 is provided on the handle core 2. The stud of the bolt 6 passes through the through hole A201. An anti-slip pad A313 is provided on the lower cover 31. A slot 321 is provided on the upper cover 32. A through hole B322 communicating with the sliding groove 311 and the slot 321 is provided on the upper cover 32. An anti-slip pad B323 is provided in the slot 321. A plug 324 is provided on the anti-slip pad B323. The plug 324 is inserted into the through hole B322. The lead screw 8 is rotatably connected to the handle 3, and one end of the lead screw 8 is threadedly connected to the lead screw nut 7. The drive assembly is set on the handle 3 and includes a worm gear 9 and a worm 10. The worm gear 9 is located inside the handle 3 and is rotatably connected to it. The worm gear 9 is coaxially connected to the lead screw 8. The worm 10 is rotatably set inside the handle 3 and meshes with the worm gear 9. A hexagonal countersunk groove 1001 is provided at one end of the worm 10 that extends out of the handle 3. In the working state, the drive assembly drives the slider 5 away from or closer to the blade 1.

[0025] Combination Figure 4 and Figure 5 The blade of a traditional knife is like Figure 5 As shown in the diagram on the left side of the blade, its thinnest point is thin, making it prone to small chips, and the blade edge has sharp angles, resulting in a jerky cutting experience; the blade in this embodiment is as follows... Figure 5 As shown in the diagram on the right side of the blade, the thinnest part of the blade tip is curved, making it less prone to small chips. It is 50% thicker than traditional blades, making it more durable, and the blade edge is smooth without any sharp edges, making it easier to cut.

[0026] In this embodiment, firstly, a worm gear 9 is installed on the lead screw 8. Then, one end of the lead screw 8 is inserted into the lead screw nut 7. Next, the slider 5 is inserted into the slide groove 311, and the worm 10 is installed and engaged with the worm gear 9. Then, the upper cover 32 and the lower cover 31 are fastened together and fixed with rivets 4 to form a complete handle 3. Next, the handle core 2 is inserted into the handle 3, and the end of the handle core 2 away from the blade 1 is inserted into the limiting groove 501 on the slider 5. Then, from the through... A bolt 6 is inserted into the countersunk hole 502 through hole A322. The stud of bolt 6 passes through through hole A201. Bolt 6 is then tightened so that its upper end does not exceed the surface of slider 5. Anti-slip pad B323 is then placed on top. When it is necessary to adjust the tightness between blade 1 and handle 3, the worm gear 10 is rotated with the help of a hex wrench. The worm gear 10 drives the worm wheel 9 and lead screw 8 to rotate, thereby pulling slider 5 through the connection between lead screw 8 and lead screw nut 7. In turn, slider 5 tightens blade 1 and handle 3. Because the blade A101 is ground into an arc-shaped structure, with the thinnest part of the blade tip being arc-shaped, the blade 101 is less prone to small chips. Furthermore, the transition between blade 101 and the blade body is smooth and without sharp edges, resulting in a smoother cutting experience without any jerking. At the same time, the serrations 102 on the back of the blade facilitate the cutting of frozen meat or bones.

[0027] Example 2

[0028] like Figure 1 and Figure 3 As shown, the present invention proposes a kitchen knife, which, compared with the first embodiment, has a flexible protective pad at the junction of the handle 3 and the blade 1, so as to prevent the fingers from directly contacting the blade 1.

[0029] In this embodiment, the blade is often thinner and has a sharper edge to make it easier to cut vegetables. Adding a flexible pad can separate the fingers from the blade 1 and prevent the fingers from being rigidly in contact with the blade 1 when cutting vegetables, thus avoiding finger abrasions.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
