Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example 1

As shown in fig. 1 to 2, a simple knife sharpener includes a positioning element 10 and a knife sharpening element 20, the knife sharpening element 20 includes a central column 21, a turntable 22 and a knife sharpening portion, in this embodiment, the knife sharpening portion can directly select a knife sharpening stone, the knife sharpening stone includes a first knife sharpening stone 231 and a second knife sharpening stone 232, the two stones have different mesh numbers and can polish and grind the knife to different degrees, a pair of turntables 22 are respectively rotatably installed on two sides of the central column 21, in this embodiment, the first knife sharpening stone 231 and the second knife sharpening stone 232 are respectively installed on the pair of turntables 22, the central column 21 drives the knife sharpening stone to rotate through the handheld translational drive turntable 22, the positioning element 10 is a positioning block 11 with a lower end face capable of being horizontally placed, a first positioning inclined plane 101 and a second positioning inclined plane 102 having different included angles with the knife sharpening stone are respectively formed on two opposite side faces of the positioning block 11, the included angle is 10-30 °, the first positioning inclined plane 101 and the second positioning inclined plane 102 are both provided with a first magnet 100 capable of adsorbing the knife 40, and adsorbing the knife positioning inclined plane on the positioning block, and the positioning block are rotated by moving/moving the positioning block, and driving the second positioning inclined plane or the positioning block to rotate the second positioning inclined plane.

As shown in fig. 4, when the simple knife sharpener is used, a steel part of a knife is fixed on a first positioning inclined surface or a second positioning inclined surface through a first magnet in an adsorption manner, the knife is inclined, the included angle between the knife and a desktop or a working surface is greater than 90 degrees, a knife edge at the end part of the knife protrudes out of the surface of a body, a knife stone is abutted against the knife edge of the knife, a central column is pushed to move by holding, a rotary disc and the knife stone are driven to move, and therefore the knife edge of the knife is ground; because the included angle between the cutter and the table top is more than 90 degrees, the lower end of the cutter is abutted against the table top or the workbench, the main acting force of the cutter grinding piece is combined to realize cutter grinding through the movement of the cutter grinding stone relative to the cutter (namely the main acting force is not towards the direction of the positioning piece), and the relatively stable state of the cutter can be kept in the cutter grinding process; for the cutting edge of guaranteeing the cutter can be in the high within range of whetstone (namely the cutting edge of cutter can butt on whetstone), the first location inclined plane and the second location inclined plane of the different contained angles that consequently set up can use the bigger first location inclined plane of contained angle to carry out the cutter to higher cutter and fix, to conventional cutter, can use the little second location inclined plane of contained angle to carry out the cutter and fix.

Therefore, in the utility model, the included angle between the first positioning inclined plane 101 and the grinding tool surface is set to be 18-30 degrees, and the included angle between the second positioning inclined plane 102 and the grinding tool surface is set to be 10-18 degrees; more specifically, the first positioning inclined plane 101 and the second positioning inclined plane 102 in the present invention are fixed inclination angles, so that the included angle between the first positioning inclined plane 101 and the grinding tool face is set to 20 degrees, and the included angle between the second positioning inclined plane 102 and the grinding tool face is set to 15 degrees; of course, other different angles may be selected, for example, on an additional positioning block, the positioning inclined plane may be set to 25 ° and 10 ° respectively, the angle combination is not limited, in the positioning block, a small included angle may be sharper, and a large included angle may be more rapidly out.

As shown in fig. 2, the utility model provides a sharpening piece 20's mounting means does, is equipped with the mounting hole on the center post 21, and the mounting hole internal fixation has bearing frame 211, and the one side of keeping away from the whetstone on carousel 22 is equipped with rotation axis 221, and rotation axis 221 is rotatable to be set up in bearing frame 211, has consequently realized the carousel for the rotatable of center post.

The utility model discloses in, the preferred cylinder of center post 21, its diameter is less than carousel 22's diameter, through the aforesaid setting, with two carousel and desktop or workstation contact, and the center post not with desktop or workstation contact, at the in-process that promotes the center post and remove, the center post can keep non-rotation state, nevertheless can realize that the carousel passes through the bearing effect and rotates, drives the whetstone and rotates, this kind of setting can avoid the center post to rotate the needs that leads to and often remove handheld position and exert the effort to the center post. Of course, as shown in fig. 1 to 2, in order to ensure the stability and durability of the sharpening unit itself when bearing force, the diameter of the central column is set to be slightly smaller than that of the turntable.

As shown in fig. 2, in this embodiment, a first mounting groove 220 is disposed on an end surface of the turntable 22 away from the central column 21, the sharpening stone can be fixedly disposed in the first mounting groove 220 by adhesion, magnetic attraction, and the like, and a side end surface protrudes out of the first mounting groove to ensure that the sharpening stone can abut against the cutting edge of the cutting tool.

In addition, when not setting up first mounting groove on the carousel, can be directly with the whetstone bonding in the middle of or magnetism inhale on the carousel.

The utility model discloses in, all be equipped with second mounting groove 103 on first location inclined plane 101 and the second location inclined plane 102, first magnet 100 can set up in second mounting groove 103 through forms such as bonding, and the side end face is leveled mutually with first location inclined plane 101 or second location inclined plane 102, and the stability of adsorbing the cutter can be guaranteed in the setting of parallel and level.

Example 2

In the utility model discloses a in another embodiment, as shown in fig. 3, its difference with embodiment 1 lies in, the portion of whetting a knife not only includes the whetstone, but included fixed disk 23 and whetstone, first whetstone 231 and second whetstone 232 are installed respectively on a pair of fixed disk 23, fixed disk 23 then can be through the spiro union, locking, paste or magnetism is inhaled on carousel 22, for example, when using the spiro union form, can set up corresponding internal and external screw thread realization on fixed disk and carousel, when using the locking form, one side that can be close to the carousel on the fixed disk sets up the screw, and one side that is close to the fixed disk on the carousel sets up the screw hole, lock through the cooperation of screw and screw hole, this kind of mode is convenient more changes the fixed disk of taking the whetstone.

In this embodiment, the whetstone can be pasted on fixed disk 23, and in order to guarantee the precision and the stability of installation whetstone, can set up fixed slot 230 on fixed disk 23, with whetstone embedding fixed slot in, but the face of whetting a knife of whetstone needs protrusion in fixed slot 230.

The utility model discloses in, locating piece 11 and center post 21 all can select for use wooden material, feel when improving the use.

The specific embodiments described herein are merely illustrative of the spirit of the invention.
