[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-3 As shown in Figure 5, a multifunctional abrasive box for a knife sharpener comprises a main body 1 and a movable part 6 capable of linearly moving relative to the main body 1, wherein mounting grooves 2 for mounting abrasives 13 are provided at the external positions of the main body 1 and the movable part 6, wherein both the main body 1 and the movable part 6 are block structures, the mounting grooves 2 are arranged at the external edge positions of the main body 1 and the movable part 6, and the inner side surfaces of the two mounting grooves 2 are arranged to be inclined toward each other, so that the abrasive 13 can be installed between the two mounting grooves 2.

[0027] When the movable part 6 moves linearly relative to the main part 1, the spacing between the mounting grooves 2 on the main part 1 and the movable part 6 can be changed, so as to be used to install abrasives 13 of different lengths; the movable part 6 is provided with a locking device for locking the movable part 6 relative to the main part 1 after its position is determined.

[0028] Specifically, one end of the main body 1 is provided with a locking rod 7 extending outward, the movable part 6 is sleeved on the locking rod 7 and slidably cooperates with the locking rod 7, and the cross-sectional profile of the locking rod 7 is rectangular, elliptical or polygonal, that is, the movable part 6 can move back and forth linearly on the locking rod 7, so as to adjust the spacing between the two mounting grooves 2. The cross-sectional profile of the locking rod 7 is non-circular, and can adopt a rectangular, elliptical or polygonal structure, which is mainly used for the movable part 6 to rotate relative to the locking rod 7.

[0029] Specifically, the locking rod 7 is provided with a plurality of positioning grooves 5 arranged at equal intervals, and the locking device includes a rotatable wrench 8 arranged on the movable part 6, and the end of the wrench 8 has a locking end 9 that can be placed in the positioning groove 5, so as to lock the movable part 6 with the main part 1. More specifically, the upper surface of the movable part 6 away from the main part 1 has two lugs, and a pin 10 is installed in the center of the two lugs. The wrench 8 is installed on the movable part 6 through the pin 10, so as to achieve a rotatable connection. The outer surface of the wrench 8 close to the hinge axis has a locking end 9 protruding outward. After the locking end 9 rotates with the wrench 8, it can be placed in the positioning groove 5 of the locking rod 7, and the friction force can be used to achieve the effect of locking the movable part 6 to the main part 1. Such a configuration has the advantage of easy operation.

[0030] Furthermore, in another embodiment, Figure 4 As shown, the hinge axis of the wrench 8 and the two lugs on the movable part 6 are arranged on a side close to the main part 1, so that specific settings can be made according to actual needs and operating habits.

[0031] The abrasive 13 is a coarse grinding stone, a fine grinding stone, an oil stone, a gem, a diamond, a ceramic, a resin or a sandpaper.

[0032] Specifically, a handle 4 is provided on the outside of the main body 1 for holding the abrasive box for sharpening.

[0033] Specifically, the main body 1 and the movable member 6 are provided with a through and coaxially arranged mounting hole 3, the cross-sectional shape of the mounting hole 3 is a regular polygon, and in this example, the cross-sectional shape of the mounting hole 3 is a square; when in use, Figure 6 As shown, the mounting rod 12 of the knife sharpener penetrates into the mounting hole 3, so that the entire abrasive box can reciprocate along the axis direction of the mounting rod 12. Since the mounting rod 12 has a swinging function, the blade of the tool clamped and fixed below can be sharpened.

[0034] In another usage state, a mounting seat 11 is provided at one end of the main body 1, and the mounting seat 11 is fixed to the end of the abrasive box by bolt connection. The L-shaped mounting rod 12 can be connected to the abrasive box through the mounting seat 11, that is, the structure of the above-mentioned mounting hole 3 is cancelled, and the grinding operation of the tool blade can also be completed.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
