DETAILED DESCRIPTION

[0024] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the present application, and cannot be understood as a limitation of the present application. In the description of the present application, it is understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "upper surface" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as a limitation of the present application.

[0025] Please refer to Figures 1-7 The present application provides an embodiment: a knife sharpener, comprising a base 1; the base 1 is provided with a circular arc-shaped guide rod 2, and the guide rod 2 is slidably installed with a sliding member 3 and a clamp 5 linked with the sliding member 3; the sliding member 3 comprises a sliding block 30, and one end of the sliding block 30 is slidably matched with the guide rod 2 through a sliding slot 34. In summary, by using the sliding of the sliding block 30 on the guide rod 2, the clamp 5 can be adjusted in angle and can be lifted synchronously, thereby ensuring the quality of the tool polishing and reducing the damage to the tool.

[0026] Specifically, since the guide rod 2 is engaged with the gear 310 provided in the sliding slot 34 through the gear slot 8, and the sliding block 30 is slid along the guide rod 2 by the rotation of the gear 310. Therefore, the rotation of the gear 310 can be used to promote the synchronous sliding of the clamp 5 on the guide rod 2.

[0027] Further, the sliding block 30 is also provided with a driving part 33, and the gear 310 is driven to rotate through the driving part 33. The sliding block 30 is also provided with a locking pin 32, and the driving part 33 is locked on the sliding block 30 through the locking pin 32. Therefore, the gear 310 can be directly driven to rotate by rotating the driving part 33 from outside, so as to further facilitate the user to adjust the position of the clamp 5. In addition, the locking of the position of the driving part 33 can be completed by buckling the locking pin 32 on the driving part 33, so as to avoid the displacement of the sliding block 30. The locking pin 32 is linked with the abutting rod 313, and the abutting rod 313 is threadedly connected with the connecting plate 314 provided on one side of the sliding block 30. Therefore, when the locking pin 32 rotates, one end of the abutting rod 313 is pressed on the guide rod 2 to complete the positioning of the sliding block 30.

[0028] Further, since the sliding groove 34 is also provided with a first guide rail 311 and a second guide rail 312, and the guide rod 2 is provided with a guide groove 9 on both sides, when the two guide rails slide along the corresponding guide grooves 9, the reliable sliding of the sliding block 30 can be further ensured, and the rotation or deviation of the guide rod 2 can be avoided.

[0029] In addition, in order to facilitate the assembly of the sliding block 30 and the guide rod 2, the first guide rail 311 is movably installed on one side of the sliding block 30. Specifically, after the first guide rail 311 is disassembled, the sliding groove 34 can be smoothly sleeved on the guide rod 2, and then the first guide rail 311 is installed on the sliding block 30. The sliding surface of the first guide rail 311 is matched with the guide groove 9, so that the sliding block 30 and the guide rod 2 can be quickly assembled.

[0030] In order to further improve the grinding quality of the tool, the guide rod 5 is also provided with a support frame 6, and the support frame 6 is slidably connected with the cross rod 7. The cross rod 7 is also provided with a grinding stone 4. Therefore, after the tool is installed on the clamp 5, the sliding block 30 is moved to make the cutting edge adhere to the grinding stone 4. At this time, the grinding stone 4 can be reciprocally pulled to complete the grinding of the cutting edge. In the process of grinding, the cross rod 7 also has the functions of guiding and limiting, so that the grinding stone 4 can stably contact with the cutting edge, and the grinding effect of the equipment on the tool is further ensured.

[0031] Embodiment one: specifically as shown in Figures 1-5 The sliding block 30 is also provided with an adjusting part 31, and the position of the clamp 5 is adjusted through the adjusting part 31. Therefore, the adjusting part 31 can be used to further adjust the position of the clamp 5 during work.

[0032] Specifically, the adjusting member 31 comprises a connecting rod 39 and a handle 38 for controlling the movement of the connecting rod 39; one end of the connecting rod 39 is connected with the clamp 5 after penetrating through the slider 30, and the other end of the connecting rod 39 is connected with the baffle 37 after penetrating through the handle 38, thus the movement of the handle 38 on the slider 30 can drive the movement of the connecting rod 39.

[0033] Further, the slider 30 is further provided with a mounting area 35, and the handle 38 is rotatably mounted in the mounting area 35; specifically, a shaft pin rod penetrates through the mounting area 35 from top to bottom to rotatably mount the handle 38 in the mounting area 35, at this time, when the handle 38 rotates clockwise in the mounting area 35, the protruding part on the handle 38 drives the baffle 37 to move towards the inner side of the mounting area 35, and further drives the connecting rod 39 to move towards the inside of the slider 30.

[0034] On the contrary, since the mounting area 35 is further provided with a spring 36, one end of the spring 36 abuts against the baffle 37, and the other end of the spring 36 abuts against the mounting area 35, when the handle 38 rotates counterclockwise, the spring 36 drives the baffle 37 to move towards the outside of the mounting area 35, and further drives the clamp 5 to move away from the guide rod 2.

[0035] Embodiment two: specifically as shown in Figures 6-7 The adjusting member 31 can also adopt a panoramic clamp seat, which is connected with the clamp and the slider 30, so that the adjusting angle of the adjusting member 31 is further increased; when the adjusting member 31 is a panoramic clamp seat, for example, a QJ-07 type clamp seat, thus the specific structure is not described here.

[0036] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
