A knife sharpener that selects different sharpening angles or different sharpening forms by rotating a sharpening component disc body with a knob includes a main body upper cover (1), a main body lower cover (2) (or a main body left cover and a main body right cover), an inner component support bracket right cover (11), and an inner component support bracket left cover (12), wherein the main body upper cover (1) is designed with different sharpening slots; a knob positioning post (13) is fixedly connected to the inner component support bracket left cover (12), and a knob assembly (16) is mounted on an outer surface of the knob positioning post (13); the inner component support bracket right cover (11) is fixedly connected with a sharpening disc body positioning post (14), and an outer surface of the sharpening disc body positioning post (14) is mounted with sharpening component disc bodies (17) with different angles; a gear positioning post (18) is fixedly connected to the inner component support bracket left cover (12), and a gear (10) is mounted on an outer surface of the gear positioning post (18); a sharpening component disc body left cover (5) is provided with a sharpening disc positioning bead (19), and the sharpening components (7) with different angles are placed in a cavity of the sharpening component disc body left cover (5); the sharpening component disc body left cover (5) is fixedly connected with a sharpening disc positioning bead positioning groove (20); 5 slots (the slots may be arranged at an interval of 3-10) on the sharpening component disc body left cover (5) and the sharpening component disc body right cover (6); a knob fitting right cover (9) is designed with a gear (21); the sharpening component disc body right cover (6) is designed with a gear (22).

A knob silicone 4, a knob fitting left cover 8, and the knob fitting right cover 9 are assembled to form a knob assembly 16, and a sharpening component 7 is mounted into the sharpening component disc body left cover 5 and the sharpening component disc body right cover 6 respectively to assemble a sharpening component disc body 17. The knob assembly 16, the sharpening component disc body 17 and the gear 10 are assembled with the inner component support bracket right cover 11 and the inner component support bracket left cover 12 respectively through screw locking to form an integral block, then the integral block is mounted into the main body lower cover 2 and fastened with buckles and screws, and then the remaining slots are also assembled by screw fastening, so as to finally close the cover to complete the assembly.

For the knife sharpener, the function setting determines the internal structure design of the knife sharpener, and the sharpening component disc body 17 performs axial movement under the transmission force of the knob assembly 16 and the gear 10. Since the sharpening components with different sharpening angles are concentrated in the sharpening component disc body 17, the required sharpening angle may be selected by turning the knob assembly 16 to sharpen the blade when the blade of the tool needs to be sharpened to varying degrees so that the blade that needs to be sharpened becomes sharper when the appropriate sharpening angle is obtained; at the same time, the position of the handle where the knob assembly 16 is located may also serve as a protection to prevent the user from being cut during the sharpening process. This solution greatly improves the use experience of the user.

The outside of the knob is made of silicone as a whole, which not only enriches the color aesthetic of the product, but also makes it more comfortable for fingers to turn it; the silicone wheel is set with numbers corresponding to different sharpening angles, making it easier and faster for users to choose the sharpening angle.

The sharpening component disc body 17 is provided with a sharpening disc positioning bead mounting hole 20.

The knob assembly 16, the sharpening component disc body 17, and the gear 10 are engaged with each other.

The knob assembly 16 and the sharpening component disc body 17 are equipped with gears with all the same parameters, and are connected through the intermediate transmission gear 10 to achieve the purpose of synchronous rotation, so that the sharpening components of the sharpening slot on the sharpening component disc body 17 correspond to the numerical designations on the silicone wheel 4 on the knob assembly 16.

The number of the sharpening slots of the multifunctional knife sharpener of the utility model (including a main body sharpening slot and a sharpening disc sharpening slot of the product appearance) may be set to 3 to 10 according to the needs. In addition, 2-4 sharpening slots with different functions may be added to the product body.

A bottom of the main body lower cover 2 is designed with an anti-slip pad, which may be in the form of glue or rubber coating, which has an anti-slip and stable effect during the knife sharpening operation.

As shown in FIG. 13, the transmission method for the knob assembly 16 and the sharpening component disc body 17 may be optimized to be driven by a gear belt.

As shown in FIG. 14, the transmission method for the knob assembly 16 and the sharpening component disc body 17 may be optimized to be driven by a silicone belt or a belt.

The working principle of the knife sharpener provided by the utility model that realizes the function of selecting multiple sharpening angles through gear transmission is as follows:

Under the premise that all parameters of the gears on the knob assembly 16 and the gears on the sharpening component disc body 17 are the same, when the knob assembly 16 is rotated, the gear on the knob assembly 16 will drive the gear 10 to rotate, and when the gear 10 rotates, the sharpening component disc body 17 will be driven to rotate, thereby realizing the function of selecting multiple sharpening angles; the positioning beads 19 inside the sharpening component disc body 17 are matched with the grooves on the sharpening disc positioning post 14 on the inner component support bracket right cover 11, and the positioning beads 19 inside the sharpening component disc body 17 will jump to a groove on the sharpening disc positioning post 14 for limitation when the knob assembly 16 rotates by one number, so that the sharpening groove on the main body upper cover 1 is matched with the sharpening groove on the sharpening disc body 17 to positioned so as to select the slots with the sharpening angle required for sharpening and at the same time limit the sharpening component disc body 17 to move around the axis without rotating.

At the same time, an optimization solution for transmission as shown in FIG. 13 and FIG. 14 is added in this patent, which is included in the utility patent and is requested to be protected together.

Additional Descriptions
