Therefore, the above terms should not be construed as limiting the present invention.

[0023] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the number.

[0024] As Figures 1-6 described, the present invention provides an angle-adjustable sharpener, including a base 1, a housing 2 provided on the base 1, and a bracket 3 provided inside the base 1. A first adjustment block 4 and a second adjustment block 5 are rotatably provided on the bracket 3. One side of the first adjustment block 4 is connected to a first sharpening stone 6, and one side of the second adjustment block 5 is connected to a second sharpening stone 7. The first sharpening stone 6 and the second sharpening stone 7 are arranged oppositely, so as to form a sharpening area between the first sharpening stone 6 and the second sharpening stone 7. An opening 8 corresponding to the sharpening area is provided on the housing 2.

[0025] By rotating the first adjusting block and the second adjusting block relative to the bracket, the first grinding stone and the second grinding stone rotate synchronously, thereby adjusting the relative angle between the first grinding stone and the second grinding stone, so as to control the grinding angle of the grinding area and improve the convenience of adjusting the grinding angle. After the grinding angle adjustment is completed, place the position to be ground of the tool at the opening, so that both sides of the position to be ground of the tool are respectively attached to the first grinding stone and the second grinding stone, and then the tool can be controlled to move back and forth for grinding treatment.

[0026] Wherein, a V-shaped groove is formed between the first grinding stone and the second grinding stone, and the tool is placed in the V-shaped groove for grinding the tool.

[0027] In an embodiment of the present solution, the first adjusting block 4 is rotationally matched with the bracket 3 through a first rotating shaft 22, and the second adjusting block 5 is rotationally matched with the bracket 3 through a second rotating shaft 23, and the first rotating shaft 22 is located between the first grinding stone 6 and the first adjusting rod 12, and the second rotating shaft 23 is located between the second grinding stone 7 and the second adjusting rod 13.

[0028] Specifically, when rotating and adjusting the first adjusting block and the second adjusting block, the first adjusting block and the second adjusting block are respectively rotated along the first rotating shaft and the second rotating shaft, so that the first grinding stone and the second grinding stone respectively take the first rotating shaft and the second rotating shaft as the rotation centers, and then the change of the grinding angle is stably controlled.

[0029] Preferably, an adjusting wheel 9 is rotatably arranged on the base 1. The adjusting wheel 9 has a first track 10 and a second track 11, and the distance between one end of the first track 10 and one end of the second track 11 is greater than the distance between the other end of the first track 10 and the other end of the second track 11; the first adjusting block 4 is connected with a first adjusting rod 12, the first adjusting rod 12 is inserted into the first track 10, the second adjusting block 5 is connected with a second adjusting rod 13, and the second adjusting rod 13 is inserted into the second track 11, so that when the adjusting wheel 9 rotates, the first adjusting rod 12 and the second adjusting rod 13 respectively move along the first track 10 and the second track 11.

[0030] Specifically, when adjusting the grinding angle, the adjusting wheel is toggled to rotate the adjusting wheel relative to the base, so that the first adjusting rod and the second adjusting rod respectively move along the first track and the second track. Since the distance between one end of the first track and one end of the second track is greater than the distance between the other end of the first track and the other end of the second track, the distance between the first adjusting rod and the second adjusting rod will gradually increase or decrease during the movement along the track, thereby controlling the size of the grinding angle and facilitating the improvement of the convenience of controlling the grinding angle.

[0031] It is worth mentioning that since the first rotating shaft is located between the first grinding stone and the first adjusting rod, and the second rotating shaft is located between the second grinding stone and the second adjusting rod, when the distance between the first adjusting rod and the second adjusting rod increases, the angle between the first grinding stone and the second grinding stone increases synchronously. Similarly, when the distance between the first adjusting rod and the second adjusting rod decreases, the grinding angle decreases synchronously.

[0032] Wherein, a number of convex teeth are provided on the outer periphery of the adjusting wheel to ensure that the user can stably push the adjusting wheel to rotate.

[0033] Preferably, both the first track 10 and the second track 11 are arranged in an arc structure so that the first adjusting rod and the second adjusting rod can be stably adjusted and moved along the first track and the second track.

[0034] Preferably, the side of the bracket 3 has a positioning pile 14, and the end of the positioning pile 14 has a positioning bead 15. A number of positioning grooves 16 are provided on the circumference of the adjusting wheel 9, and the positioning grooves 16 match the positioning beads 15.

[0035] Specifically, the circumferential limit of the adjusting wheel is carried out through the positioning groove and the positioning bead. When the adjusting wheel is rotated, the positioning bead is buckled along each positioning groove, increasing the force required when the adjusting wheel rotates. Furthermore, after the user completes the adjustment, the positioning bead can limit the positioning groove to keep the adjusting wheel stable, thereby ensuring the stability of the grinding angle.

[0036] It is worth mentioning that the installation of the adjusting wheel, the cooperation between the positioning bead and the positioning groove are all clearance fits, and the structures such as the positioning groove and the positioning bead all have a certain degree of material deformation ability to ensure that the adjusting wheel can rotate stably and is limited by the positioning bead.

[0037] Preferably, the base 1 is provided with a number of connecting columns 17, and the bracket 3 is installed on the connecting columns 17.

[0038] Specifically, the stability of the bracket is increased through a number of connecting columns, and at the same time, the bracket is installed on the connecting columns through connecting pieces such as bolts to ensure the stable support of the bracket for structures such as the first adjusting block and the second adjusting block.

[0039] Preferably, a first positioning rod 18 is provided on one side of the base 1 close to the adjusting wheel 9, and a first positioning hole 19 is provided at the middle position of the adjusting wheel 9 so that the first positioning rod 18 is inserted into the first positioning hole 19.

[0040] Specifically, through the cooperation between the first positioning rod and the first positioning hole, the adjusting wheel can rotate relative to the first positioning rod, improving the stability when the adjusting wheel rotates.

[0041] Preferably, a second positioning rod 20 is provided on one side of the bracket 3 close to the adjusting wheel 9, and a second positioning hole 21 is formed in the middle position of the adjusting wheel 9, so that the second positioning rod 20 is inserted into the second positioning hole 21.

[0042] Specifically, through the cooperation of the second positioning rod and the second positioning hole, the adjusting wheel is simultaneously limited by the first positioning rod and the second positioning rod, further increasing the rotational stability of the adjusting wheel and avoiding problems such as shaking of the adjusting wheel.

[0043] The present invention is not limited to the above-mentioned best embodiment, and any person can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as it has the same or similar technical solutions as the present application, it falls within the protection scope of the present invention.
