[0027] The multifunctional knife sharpener for switching the sharpening mode by pressing a button comprises a shell 1 composed of a left shell 11 and a right shell 12, wherein the shell 1 is divided into a gripping portion and a sharpening portion, wherein the sharpening portion is arranged in a cavity structure, wherein a rotatable sharpening disc 2 is arranged in the inner cavity of the sharpening disc 2, wherein a plurality of different sharpening members 3 are arranged at intervals on the outer edge of the sharpening disc 2, and a sharpening groove 13 is provided on the surface of the sharpening portion of the shell 1 for exposing the sharpening member 3.

[0028] The shell 1 can be made of high-strength plastic or lightweight metal such as aluminum alloy. When in use, the grip portion is grasped, and the sharpening member 3 on the sharpening disc 2 is exposed from the sharpening groove 13, and the cutting edge of the knife is put into the sharpening groove 13 for sharpening.

[0029] The plurality of sharpening members 3 can be sharpening members with the same angle and different forms, for example, two of the sharpening members have the same angle, but the sharpening members are in the form of a sheet and a column, or in the form of fine grinding and fine grinding. Sharpening members with different angles and forms can also be set.

[0030] Knife sharpening materials in the form of coarse grinding, fine grinding, precision grinding, single-edged knife sharpening, scissors sharpening, etc. can also be assembled as needed, or sharpening grooves for flexible grinding and knife maintenance, and grooves for scissors sharpening can be added to increase the different functions of the sharpener to enhance the user experience and expand the scope of use.

[0031] The right shell 12 is provided with a button 14 that can be pressed inwards, and the inner cavity of the shell 1 is provided with a rotating mechanism 4 that drives the sharpening disc 2 to rotate through the button 14.

[0032] By pressing the button 14, the rotating mechanism 4 is driven to rotate, and then the sharpening disc 2 is driven to rotate, so as to adjust the position of each sharpening member 3, so that the sharpening member 3 to be used is rotated to the position of the sharpening groove 13 to be exposed for use.

[0033] The rotating mechanism 4 includes a fixed cylinder 41 with an open right end, a left rotating sleeve 42, a spring 43 and a right rotating sleeve 44, the left end of the fixed cylinder 41 is fixedly connected to the inner wall of the left shell body 11, the left rotating sleeve 42 is movably sleeved on the surface of the fixed cylinder 41, the right end face of the left rotating sleeve 42 is provided with a first corrugated portion 422 along its annular surface, the left end face of the right rotating sleeve 44 is provided with a second corrugated portion 441 matched with the first corrugated portion 422 along its annular surface, the left rotating sleeve 42 and the right rotating sleeve 44 are fixedly connected to form a cylindrical structure, there is a gap between the first corrugated portion 422 and the second corrugated portion 441 to form a corrugated channel, the right end face of the left rotating sleeve 42 is provided with a positioning groove 421 connected to the corrugated channel, and the left end of the surface of the fixed cylinder 41 is provided with three guide posts 411 moving in the corrugated channel and the positioning groove 421.

[0034] The surface of the right rotating sleeve 44 is fixedly connected with an elastic fixing plate extending from the surface of the left rotating sleeve 42. A clamping hole is provided on the fixing plate. A raised clamping block is provided on the surface of the left rotating sleeve 42. The clamping block is clamped into the clamping hole to fix the left rotating sleeve 42 and the right rotating sleeve 44 together, so that the two form an integral cylindrical structure that moves synchronously.

[0035] Each trough position of the first corrugated portion 422 is provided with a positioning groove 421. When the guide post 411 is inserted into the positioning groove 421, the cylindrical structure cannot rotate. When the cylindrical structure moves to the left along the surface of the fixed cylinder 41, the spring 43 is compressed to generate elastic force, and the guide post 411 is separated from the positioning groove 421 and enters an inclined path of the corrugated channel. When the cylindrical structure continues to move, under the guiding effect of the guide post 411 and the inclined path of the corrugated channel, the cylindrical structure will rotate while moving to the left on the surface of the fixed cylinder 41. The direction of rotation is determined by the direction of the inclined path of the corrugated channel, and the rotation is always maintained in the same direction. When adjusted to a suitable position, release the button 14, and under the elastic force of the spring 43, the cylindrical structure resets to the right, so that the guide post 411 is inserted into a corresponding positioning groove 421, thereby achieving locking.

[0036] The sharpening disc 2 is nested in the surface of the cylindrical structure, the inner side of the button 14 abuts against the right end of the right rotating sleeve 44, the spring 43 is fixedly connected to the inner cavity of the fixed cylinder 41 and the other end abuts against the inner cavity of the right rotating sleeve 44, when the button 14 is pressed, the cylindrical structure slides on the surface of the fixed cylinder 41 and is guided to rotate by the guide column 411.

[0037] The button 14 is rotatably connected to the right end of the right rotating sleeve 44, that is, the two can rotate relative to each other, ensuring that the button 14 does not rotate synchronously with the cylindrical structure.

[0038] The knife sharpening disc 2 is composed of a left disc body 21 and a right disc body 22. A through hole for being nested in the rotating mechanism 4 is provided at the center of the knife sharpening disc 2. A raised guide block 15 is provided on the inner wall of the through hole. A guide groove adapted to the guide block 15 is provided on the surface of the cylindrical structure formed by the left rotating sleeve 42 and the right rotating sleeve 44.

[0039] The knife grinding disc 2 is embedded in the surface of the cylindrical structure, so that when the cylindrical structure rotates, the knife grinding disc 2 rotates synchronously, and the guide block 15 is embedded in the guide groove and can move in the guide groove, so that the knife grinding disc 2 and the cylindrical structure can produce relative movement in the left and right directions, that is, the knife grinding disc 2 is stationary in the left and right directions while the cylindrical structure moves left and right. Due to the limitation of the outer shell 1, the knife grinding disc 2 itself cannot move left and right and can only rotate. Therefore, when the cylindrical structure moves left and right, the knife grinding disc 2 moves in the guide groove through the guide block 15, so that the knife grinding disc 2 will not move left and right with the cylindrical structure, but can rotate with the cylindrical structure.

[0040] The corrugated channel is distributed along the annular surface of the middle section of the cylindrical structure, and the number of wave crests and troughs of the corrugated channel matches the number of sharpening elements on the sharpening disc 2, so that when the cylindrical structure rotates a certain angle, when the guide post 411 is inserted into one or more adjacent positioning grooves 421, exactly one sharpening element 3 is in the working position. When the guide post 411 is inserted into the positioning groove 421, it also plays a role in locking and limiting the sharpening disc 2.

[0041] The inner wall surface of the left shell body 11 is provided with a screw column 5 which passes through the outer wall surface thereof. The left end of the fixing tube 41 is fixed to the screw column 5 by means of a screw. The rear end of the fixing tube 41 is provided with a threaded hole. The fixing tube 41 is tightened and fixed to the screw column 5 by screwing in the screw from the outer side of the left shell body 11.

[0042] A fixing ring is disposed on the inner wall of the left housing 11 at the outer circle of the screw column 5, and the rear end of the fixing tube 41 is inserted into the fixing ring, and the fixing ring is used for auxiliary support and fixing.

[0043] The arrangement positions of the components can be adjusted and installed according to the space size in the installation cavity and the volume size of the parts to ensure that the components can operate normally without interfering with each other.

[0044] The right housing 12 is provided with a button hole 6 for the button 14 to move, and the surface of the right housing 12 is provided with an indicating arrow 7 for indicating the rotation direction of the knife sharpening disc 2 .

[0045] Anti-skid pads 8 are respectively arranged at the front and rear ends of the bottom of the housing 1, so that the housing 1 can be placed on a table for use and prevented from sliding during use.

[0046] like Figure 7 As shown, the number of slots for mounting the sharpening element 3 on the sharpening disc 2 can be adjusted according to demand, and can be set to 3 to 8, with one sharpening element being arranged in each slot.

[0047] The working principle of the multifunctional knife sharpener provided by the utility model by switching the knife sharpening mode by pressing a button is as follows:

[0048] When the button 14 is pressed, the cylindrical structure composed of the left rotating sleeve 42 and the right rotating sleeve 44 will move leftward relative to the grinding disc 2. When the cylindrical structure moves leftward along the surface of the fixed cylinder 41, the spring 43 is compressed to generate elastic force, and the guide column 411 disengages from the positioning groove 421 and enters an inclined path of the corrugated channel. When the cylindrical structure continues to move, under the guiding effect of the guide column 411 and the inclined path of the corrugated channel, the cylindrical structure will rotate while moving leftward on the surface of the fixed cylinder 41, and then drive the grinding disc 2 to rotate, thereby adjusting the position of each grinding piece 3, so that the grinding piece 3 to be used is rotated to the position of the grinding groove 13 to be exposed for use. When adjusted to a suitable position, release the button 14. Under the elastic force of the spring 43, the cylindrical structure resets to the right, so that the guide column 411 is stuck in a corresponding positioning groove 421, thereby realizing locking after adjustment.

[0049] Compared with the related art, the multifunctional knife sharpener provided by the utility model which switches the knife sharpening mode by pressing a button has the following beneficial effects:

[0050] By pressing the button 14, the rotating mechanism 4 is driven to rotate, thereby driving the sharpening disk 2 to rotate, so as to adjust the position of each sharpening member 3 on the sharpening disk 2, so that the sharpening member 3 to be used is moved to the sharpening groove 13 for use. A plurality of sharpening members 3 in different formats can be arranged on the sharpening disk 2, and the adjustment is made by pressing the button 14, so that the entire device can simultaneously have a plurality of sharpening members of different angles and different forms for selection, and can be freely selected according to the cutting edge angle of the tool, so as to meet the sharpening needs of a variety of tools. While being able to select a plurality of different sharpening angles for sharpening, the same sharpener can also be equipped with a grinding function and other functions such as scissors sharpening for use together, so as to enrich the versatility of the product and increase the different types of sharpening needs of users.
