Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpeners, in particular to a foldable knife sharpener. Background Art

[0002] Knife sharpeners are suitable for a variety of kitchen knives, outdoor knives, scissors, Damascus knives, and ceramic knives. They come in a variety of styles, including sharpening rods and whetstones. With the continuous advancement of technology, the production process and material quality of knife sharpeners are gradually improving, leading to a continued growth in market demand. Handheld knife sharpeners are convenient and efficient sharpening tools. Existing handheld knife sharpeners typically consist of a cylindrical shape connected to a handheld rod. These are long, cannot be folded, and are difficult to carry. Utility Model Content

[0003] The present invention aims to overcome at least one of the above-mentioned defects of the prior art and provide a foldable knife sharpener to achieve the purpose of simple structure, compactness and easy storage.

[0004] Specifically, the utility model protects a foldable knife sharpener, comprising a first handle, a second handle and a sharpener body, wherein the first handle and the second handle are respectively rotatably connected to one end of the sharpener body, and the rotation direction of the first handle is opposite to the rotation direction of the second handle; a first accommodating groove is provided on one side of the first handle, and a second accommodating groove is provided on one side of the second handle; by rotating the first handle and the second handle in opposite directions, the sharpener body is embedded in the storage cavity formed by the first accommodating groove and the second accommodating groove.

[0005] The first and second handles are generally slightly wider than the sharpener body. In the unfolded state, a first receiving groove and a second receiving groove are respectively provided on the outer sides of the first and second handles. By rotating the first and second handles relative to each other, the free ends of the first and second handles approach the sharpener body, and eventually the first and second handles are brought together, so that the sharpener body is completely stored in the storage cavity. By rotating the first and second handles in opposite directions, the sharpener body is separated from the storage cavity, and eventually the free ends of the first and second handles are brought together to form a single handle. By holding the entire handle, the sharpener body can be used to sharpen a knife.

[0006] Furthermore, the rotation angle between the first handle and the second handle relative to the sharpener body is 0-180°.

[0007] Furthermore, the edge of the first receiving groove is concave to form a first gripping position, and the edge of the second receiving groove is concave to form a second gripping position. In the open state, the hand grips the edges of the first and second receiving grooves. Therefore, the concave structure makes it easier to fit the hand position, making the grip more stable and providing a better user experience.

[0008] Furthermore, the other side of the first and second handles is provided with anti-slip grooves. More preferably, the first and second handles are provided with anti-slip grooves on both the upper and lower surfaces. When the sharpener body is stored, the handheld portion is the other side of the first and second handles, thus preventing slipping by designing the anti-slip grooves.

[0009] Furthermore, the sharpener body includes a fixedly connected sharpening part and a connecting part, the connecting part is provided with a first screw hole and a second screw hole; the first handle is rotatably connected to the first screw hole by a screw; the second handle is rotatably connected to the second screw hole by a screw.

[0010] Furthermore, the width of the connecting portion is greater than the width of the sharpener body. Since the connecting portion primarily serves as a connection, and the combined width of the first and second handles is greater than the width of the sharpener body, the width of the connecting portion needs to be greater than the width of the sharpener body to facilitate the detachable, rotatable connection between the connecting portion and the handles.

[0011] Furthermore, the connecting end of the first handle is provided with a first embedding groove, which is connected to the first receiving groove; the connecting end of the second handle is provided with a second embedding groove, which is connected to the second receiving groove; one side of the connecting portion is embedded in the first embedding groove, and the other side of the connecting portion is embedded in the second embedding groove, and the upper and lower surfaces of the connecting portion are respectively connected to the first handle by a group of the screws; and the second handle is connected by another group of the screws. In order to facilitate the rotation of the first and second handles, the utility model is provided with a first embedding groove at the connecting end of the first handle and a second embedding groove at the connecting end of the second handle; at this time, the connecting end of the first handle forms two connecting pieces, and the connecting end of the second handle also forms two connecting pieces, and then one side of the connecting portion is embedded in the first embedding groove, and the other side of the connecting portion is embedded in the second embedding groove, so that one side of the connecting portion is embedded between the two connecting pieces of the first handle, and the other side of the connecting portion is embedded between the two connecting pieces of the second handle, and the two connecting pieces are respectively connected to the connecting portion by screws to achieve rotation.

[0012] Furthermore, the screw member includes a cross countersunk screw and a wave spring washer.

[0013] Furthermore, a hanging hole is provided at the tail of the first handle and / or the second handle.

[0014] Furthermore, the first handle and / or the second handle are provided with a groove, and a patch is provided on the groove. The patch can be affixed with a logo or label according to design requirements for easy use.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The knife sharpener of the utility model has a compact structure. By rotating and folding the two sides, the knife sharpener body can be completely stored in the storage cavity formed by the handle, taking up little space. At the same time, the rotating storage method is simple to operate and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
