[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1-7 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the gear transmission gear-adjustable multifunctional knife sharpener provided by the utility model; Figure 2 for Figure 1 The structural diagram of the left cover of the main body is shown; Figure 3 for Figure 2 The structural diagram of the left cover of the main body is shown; Figure 4 for Figure 1 The structural diagram of the right cover of the main body is shown; Figure 5 for Figure 1 The structural diagram of the right cover of the main body is shown; Figure 6 for Figure 5 The schematic diagram of the internal structure of the knife sharpening disc shown; Figure 7 The present invention provides a gear transmission gear-shifting multifunctional knife sharpener in another transmission mode. The gear transmission gear-shifting multifunctional knife sharpener comprises a main body left cover 1 and a main body right cover 2, the main body left cover 1 is fixedly connected with a knob positioning column 3, the outer surface of the knob positioning column 3 is mounted with a knob 4, the main body left cover 1 is fixedly connected with a grinding disc positioning column 5, the outer surface of the grinding disc positioning column 5 is mounted with a grinding disc disc body 6, the main body left cover 1 is fixedly connected with a gear positioning column 7, the outer surface of the gear positioning column 7 is mounted with a gear 8, the knob positioning bead 9 is arranged on the knob 4, the grinding disc disc body 6 is arranged with a grinding disc positioning bead 10, the main body right cover 2 is fixedly connected with a grinding disc positioning bead positioning groove 11, the main body right cover 2 is provided with a knob positioning bead positioning hole 12, and the tops of the main body left cover 1 and the main body right cover 2 are provided with a grinding disc groove 13.

[0024] Install the knob 4 and the grinding disc body 6 into the knob positioning bead 9 and the grinding disc positioning bead 10 respectively, install the gear 8 into the left cover gear positioning column 7, install the knob 4 and the grinding disc body 6 into the gear 8 through the knob positioning column 3 and the grinding disc positioning column 5 respectively, and combine the left cover and the right cover by means of a tight fit of the pillars to achieve installation.

[0025] The function setting of the knife sharpener determines the internal structure design of the knife sharpener. The knife sharpener disc 6 moves axially in the left and right cover cavities under the driving force of the knob 4 and the gear 8. Since the knife sharpener disc 6 contains knife sharpeners with different grinding degrees and different sharpening methods, when the knife blade needs to be sharpened to different degrees, the required sharpening method can be selected by rotating the knob 4 to sharpen the knife blade, so that the knife blade that needs to be sharpened becomes sharper when the appropriate sharpening method is obtained. At the same time, the position of the handle where the knob 4 is located can also play a protective role to prevent the user from being cut during the sharpening process. The user experience is greatly improved.

[0026] The knob 4 is provided with a knob positioning bead mounting hole 14 , and the sharpening member disc body 6 is provided with a grinding disc positioning bead mounting hole 15 .

[0027] The knob 4, the sharpening disc 6 and the gear 8 are meshed with each other.

[0028] The knob 4 and the sharpening plate 6 are equipped with gears with the same parameters, which are connected through an intermediate transmission gear 8 to achieve the purpose of synchronous rotation, so that the sharpening grooves on the sharpening plate 6 correspond to the markings on the knob 4.

[0029] The number of the knife sharpening grooves of the multifunctional knife sharpener of the utility model (including the knife sharpening grooves of the product appearance body and the knife sharpening grooves of the grinding disc) can be set to 2 to 8 according to the needs.

[0030] The grinding disc positioning bead positioning groove 11 is designed with a plurality of evenly distributed positioning notches around the axis, and is matched with the grinding disc positioning bead 10 on the grinding disc body 6 .

[0031] The knob positioning bead positioning hole 12 is designed with a plurality of evenly distributed positioning grooves around the axis, which are matched with the knob positioning bead 9 .

[0032] The bottom of the main body left cover 1 and the main body right cover 2 are designed with anti-skid pads in the form of glue sticking or rubber wrapping, which play an anti-skid and stable effect during the knife sharpening operation.

[0033] Depend on Figure 6 As shown, the transmission mode of the gear 8 can be adjusted by connecting the knob 4 and the sharpening plate 6 with a belt, a rubber ring and / or a gear belt.

[0034] The working principle of the gear transmission gear-adjustable multifunctional knife sharpener provided by the utility model is as follows:

[0035] The left cover 1 of the main body is assembled with the right cover 2 of the main body through the tight-fitting pillar. Under the premise that all parameters of the gear on the knob 4 and the gear on the grinding disc 6 are the same, when the knob 4 is turned, the gear on the knob 4 will drive the gear 8 to rotate, and when the gear 8 rotates, the grinding disc 6 will be driven to rotate, thereby realizing the function of gear shifting. The knob positioning bead 9 on the knob 4 and the grinding disc positioning bead 10 on the grinding disc grinding disc 6 are matched with the positioning notch and positioning groove on the right cover 2 of the main body. When the knob 4 is turned, the gear 8 will rotate. When the knob 4 is rotated one gear, the knob positioning bead 9 will jump a groove for limitation, and the knob 4 will drive the gear 8 to transmit while rotating, and the gear 8 will drive the sharpening disc body 6 to rotate. At the same time, the grinding disc positioning bead 10 on the sharpening disc disc body 6 will rotate a groove in the grinding disc positioning bead positioning groove 11 for limitation, so that the sharpening groove on the main body and the sharpening groove on the sharpening disc body 6 are matched and positioned, so as to call the notch required for sharpening and at the same time limit the sharpening disc body 6 to move around the axis while not rotating.

[0036] Compared with the related art, the gear transmission gear-adjustable multifunctional knife sharpener provided by the utility model has the following beneficial effects:

[0037] When the sharpening method is changed by the sharpening disc 6, the gear can be adjusted at different positions, and the knob 4 and the sharpening disc 6 can be simultaneously shifted by the transmission method of the gear 8. When the knob 4 is transmitted by the gear 8, the constraint of the sharpening disc 6 in the actual conversion work can be strengthened, so that it will not easily rotate while sharpening, which enhances the stability of sharpening to a certain extent. Sharpening parts with various grinding precisions and multiple types of tools are evenly distributed in one sharpening disc 6 in the form of a disc, and the gears are adjusted and used by axial rotation and gear shifting, which can enhance the user's different usage experience.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
