Abstract

The invention discloses a cutter grinder mainly comprising a handle, a rough grinding stone, and an accurate grinding stone. The handle comprises a handheld part and an accommodating cavity. The bottom of the accommodating cavity is provided with a rotating shaft. The rotating shaft is provided with a core. The upper portion of the core is disposed inside the accommodating cavity. The rotating shaft can drive the core to rotate. Both the rough grinding stone and the accurate grinding stone are in semi-arc structures of certain thickness. The rough grinding stone and the accurate grinding stone symmetrically cover the core. Butt joint parts of the rough grinding stone and the accurate grinding stone are provided with symmetric clamp grooves. The sidewall of the handle is provided with a fastening mechanism used for fastening the rough grinding stone and the accurate grinding stone. The rough grinding stone and the accurate grinding stone are replaced by rotating the rotating shaft; the sidewall of the handle is provided with the fastening mechanism used to fasten the stones adjusted, rough grinding while accurate grinding is avoided, grinding precision is improved, and the service life of a cutter is prolonged; the cutter grinder is simple in structure, small in size, free of powering on, and widely applicable.

Description

A kind of knife sharpening device

Technical field

The present invention relates to cutter auxiliary equipment field, specifically a kind of knife sharpening device.

Background technology

In daily life, cutter be people live institute requisite, no matter cut the dish, meat cutting etc. all be unable to do without cutter, cutter has been used of a specified duration will be more blunt, need to polish to it, existing Domestic knife-sharpening device is more for kitchen, they are all electronic mostly, structure is comparatively complicated, after energising, just can work, or the area that falls behind a little any is the simple square grinding stone of a block length, or the grinding stone of tubulose, tubulose grinding stone is to sell meat market comparatively common, butcher can polish several times before meat cutting on two different grinding stones, the one, corase grind, refining, when cutter is polished, to polish with two different grinding stones, also there is now existing coarse-grained stone on same grinding stone also to have fine grinding stone, but during manual polishing, that distinguishes is inaccurate, while keeping away unavoidable polishing, make cutter polishing inhomogeneous, the service life of impact polishing precision and cutter.

Summary of the invention

In order to solve the problems of the technologies described above, the present invention proposes a kind of knife sharpening device, this device can be roughly ground cutter, also can be to correct grinding of tooth, polishing precision is high, and cutter life is long.

Object of the present invention is carried out specific implementation by the following technical programs:

A kind of knife sharpening device, mainly comprise handle, coarse-grained stone, fine grinding stone, described handle comprises grip part and container cavity, the bottom of described container cavity is provided with a rotating shaft, in described rotating shaft, be provided with iron core, the top of described iron core is arranged in container cavity, rotating shaft can drive iron core to rotate, described coarse-grained stone is and has certain thickness semi arch structure with fine grinding stone, coarse-grained stone is coated on iron core with fine grinding stone symmetry, in coarse-grained stone and the joint of fine grinding stone, be symmetrically arranged with draw-in groove, on the sidewall of handle, being provided with can be by coarse-grained stone and the stuck clamping body of fine grinding stone.

Described clamping body comprises card handle and dop, described dop can match with draw-in groove, and described card handle is fold-line-shaped, is provided with a bearing on the sidewall of described handle, described card handle is movably connected on bearing by bearing pin, between the card tail end of handle and the sidewall of handle, is provided with stage clip.

Described grip part is fan-shaped, and the width of described grip part is greater than the width that holds container cavity.

A kind of knife sharpening device of the present invention, there is coarse-grained stone and fine grinding stone, by rotating shaft, change coarse-grained stone and fine grinding stone, and be provided with gripping mechanism on the sidewall of handle, unit state after adjusting can be clamped, there will not be the situation of simultaneously not only roughly grinding but also refining, improved polishing precision, extended the service life of cutter, and this apparatus structure is simple, volume is little, and without energising, the scope of application is extensive.

Accompanying drawing explanation

According to drawings and embodiments the present invention is described in further detail below.

Fig. 1 is the main TV structure schematic diagram of a kind of knife sharpening device of the present invention;

Fig. 2 is the left TV structure schematic diagram of a kind of knife sharpening device of the present invention.

In figure: 1-handle; 2-card handle; 3-rotating shaft; 4-refines stone; 5-coarse-grained stone; 6-dop; 7-bearing pin; 8-stage clip; 9-draw-in groove; 10-iron core.

The specific embodiment

As Fig. 1, shown in 2, a kind of knife sharpening device described in the embodiment of the present invention, mainly comprise handle 1, coarse-grained stone 5, fine grinding stone 4, handle 1 comprises grip part and container cavity, the bottom of container cavity is provided with a rotating shaft 3, in rotating shaft 3, be provided with iron core 10, the top of iron core 10 is arranged in container cavity, rotating shaft 3 can drive iron core 10 to rotate, coarse-grained stone 5 is and has certain thickness semi arch structure with fine grinding stone 4, coarse-grained stone 5 is coated on iron core 10 with fine grinding stone 4 symmetries, in coarse-grained stone 5 and the joint of fine grinding stone 4, be symmetrically arranged with draw-in groove 9, draw-in groove 9 is a semicircle, on the sidewall of handle 1, being provided with can be by coarse-grained stone 5 and the stuck clamping body of fine grinding stone 4.

Preferably, clamping body comprises card handle 2 and dop 6, dop 6 can match with draw-in groove 9, card handle 2 is fold-line-shaped, on the sidewall of handle 1, be provided with a bearing, card handle 2 is movably connected on bearing by bearing pin 7, between the card tail end of handle 2 and the sidewall of handle 1, is provided with stage clip 8, and stage clip 8 is stuck in all the time in draw-in groove 9 dop 6 under the effect that there is no external force.The grip part of handle 1 is fan-shaped, and the width of grip part is greater than the width that holds container cavity, is convenient to manual polishing cutter.

The present invention in use, holds the tail end of card handle 2, makes dop 6 depart from draw-in groove 9, hand rotation rotating shaft 7, is first transferred to bottom by coarse-grained stone 5, is exposed at the outside of container cavity, after adjusting, unclamp card handle 2, dop 6 is entered in draw-in groove 9, two grinding stones are stuck, roughly grind, after corase grind, repeat above-mentioned action, fine grinding stone 4 is adjusted to behind bottom stuck, refined, after having refined, complete once-through operation.

Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; its technical scheme that still can record aforementioned each embodiment regulates; or part technical characterictic is wherein equal to replacement; within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
