[0038] Specifically, the provision of the blocking part 103 can effectively prevent the drawer box 2 from sliding in too deep and prevent the drawer box 2 from continuing to slide forward, thereby ensuring that the drawer box 2 stays in the correct position.

[0039] Furthermore, as Figure 2 and Figure 5 shown, a rib 1011 is provided on the installation cavity 101. When the drawer box 2 slides into the installation cavity 101, the outer contour of the drawer box 2 is in close contact with the rib 1011.

[0040] Specifically, convex ribs 1011 are provided inside the installation cavity 101. When the drawer box 2 slides into the installation cavity 101, the outer contour of the drawer box 2 is in close contact with the convex ribs 1011, ensuring that the drawer box 2 can slide smoothly when sliding in, and at the same time remaining stable after sliding in and not being prone to shaking; the presence of the convex ribs 1011 also reduces the direct contact and friction between the drawer box 2 and the side wall of the installation cavity 101, improving the durability of the overall structure.

[0041] Furthermore, as Figure 2 , Figure 3 and Figure 5 shown, the knife sharpening mechanism 3 includes more than one grinding wheel 302 for grinding the cutting edge of the knife.

[0042] Specifically, multiple grinding wheels 302 can be arranged at different positions and angles to grind different parts of the knife respectively. The user inserts the knife into the knife sharpening slot 3031, and performs the grinding operation through the rotation of the grinding wheel 302. The metal chips fall into the drawer box 2 below. After the grinding is completed, the drawer box 2 is slid out through the handle part 201 of the drawer box 2 to clean the chips.

[0043] Furthermore, as Figure 2 and Figure 3 shown, a driving motor 4 for driving the knife sharpening mechanism 3 to work is provided inside the machine body 1. The knife sharpening mechanism 3 further includes a limiting member 301. More than one grinding wheel 302 is fixedly installed on the output shaft of the driving motor 4 through the limiting member 301. The grinding wheel 302 is located inside the installation cavity 101 and above the drawer box 2.

[0044] Specifically, the driving motor 4 drives multiple grinding wheels 302 to work through the output shaft, ensuring that the grinding wheels 302 can perform the grinding operation efficiently and stably, improving the grinding effect; the limiting member 301 fixedly installs the grinding wheels 302, ensuring that the grinding wheels 302 will not loosen or shift during high-speed rotation, guaranteeing the precision and safety of grinding, and the grinding wheels 302 are fixed through the limiting member 301, so that the user can conveniently disassemble and replace the grinding wheels.

[0045] Furthermore, as Figure 2 and Figure 5 shown, the knife sharpening mechanism 3 further includes a cover body 303 covering the grinding wheel 302, and a knife sharpening slot 3031 is provided on the cover body 303 corresponding to the grinding wall of the grinding wheel 302.

[0046] Specifically, the cover body covers the grinding wheel, which can effectively prevent metal chips and the grinding wheel 302 from flying out accidentally during the grinding process, protecting the safety of the user; the setting of the knife sharpening slot 3031 helps the user to insert the knife more accurately, ensuring the precision and effect of grinding.

[0047] Furthermore, as Figure 3 and Figure 5 ​As shown, a cooling fan 5 for cooling the drive motor 4 is also provided inside the body 1, and the cooling fan 5 is connected to the output shaft of the drive motor 4.

[0048] Specifically, when the drive motor 4 operates, the fan 5 rotates synchronously to discharge the heat from around the drive motor 4 and prevent the motor from overheating.

[0049] Furthermore, as Figure 3 and Figure 5 shown, a baffle 104 for preventing the air discharged by the fan from flowing into the installation cavity 101 is provided inside the body 1. The baffle 104 can further prevent the dust from spreading and improve the cleaning effect.

[0050] Furthermore, the drawer box 2 is an integrally formed structure.

[0051] Specifically, the integrally formed process simplifies the production process, improves the production efficiency, and reduces the manufacturing cost.
