Abstract

The utility model relates to a portable cutter grinder, which mainly comprises a support and a cutter-grinding unit arranged on the support. The cutter-grinding unit consists of a grinding wheel which is positioned on a supporting axle inside side plate of the support. A profiling mould is arranged inside the grinding wheel; meanwhile, a profiling mould, a spring, a nut and washer are positioned in turn outside the grinding wheel. With the technical scheme that sphere profiling moulds are respectively arranged inside and outside the grinding wheel on the supporting axle of the support, the disadvantages that general grinding unit is inefficient and unsafe are overcome. Compared with beneficial effect produced by prior arts, the utility model has advantages as following: (1) the grinding angle of edge can be automatically adjusted and controlled, and coarse and fine grinders can be used at the same time to achieve good grinding effects and high efficiency; (2) no need complex techniques due to convenient operation and easy control; (3) it can be operated with one hand with excellent security. (4) Characterized in simple and compact structure, small volume, extensive material selections, low production cost and easy usage as well as the base plate secured optionally on chopping board or on wall by a suction cup. Thereby, the utility model is extensively applicable for various cutters.

Description

Portable knife sharpener

Technical field

The utility model relates to a kind of knife-grinding appliance, especially a kind of portable knife sharpener.

Background technology

Cutter is people's articles for daily use, as the kitchen knife of the usefulness of cooking is the thing of herbal, however the easy blunt file of the cutting edge of a knife or a sword mouth of kitchen knife, and the kitchen knife of the blunt file of cutting edge of a knife or a sword mouth not only uses very inconvenient, and wafts easily and slide to finger and make hand injured.Therefore, knife-grinding appliance has become the thing of herbal.

Existing people's knife-grinding appliance used in everyday is very simple, and for example, most people are to use whetstone or instruments sharpenning bar to make knife-grinding appliance.During use, the two sides of cutter is scraped up and down along whetstone or instruments sharpenning bar, can finish the sharpening function, but the use of whetstone and instruments sharpenning bar needs certain skill and strength, the major family of family is difficult to grasp, as use inconsiderate just easily handle scratch.

Summary of the invention

At above-mentioned situation, the purpose of this utility model is to provide a kind of portable knife sharpener that grinding angle is controlled automatically and efficient is higher of simple in structure, esy to use, safe and reliable, knife face cutting edge of a knife or a sword mouth.

For achieving the above object, a kind of portable knife sharpener, it mainly comprises stake body and the knife sharpening device that is arranged on the stake body, its knife sharpening device comprises an emery wheel, this emery wheel is located on the interior bolster of stake body side plate, pattern is established in the inboard of described emery wheel, and the outside of described emery wheel is provided with pattern, spring, nuts and washers in regular turn.

For implementation structure optimization, its further step also has:

Described emery wheel is two, and one is coarse plain emery wheel, and another is a fine grinding wheel, and their symmetries are laid in the middle place of bolster.

Described pattern is a spherical surface body.

The side plate of described stake body is two, and the base of they and stake body constitutes the U-shaped shape.

The side plate of described stake body is a triangle.

The base of described stake body is provided with several suckers.

The utility model is used in the technical scheme that the spherical surface body pattern is established in the emery wheel medial and lateral of stake body bolster, and it is low and use unsafe defective to have overcome common knife-grinding appliance sharpening efficient.The beneficial effect that the utility model is produced compared to existing technology: (1) but the grinding angle auto-control of knife face cutting edge of a knife or a sword mouth, corase grind, fine grinding uses simultaneously, ground effect is good, the efficient height; (2) do not need complicated sharpening skill, easy to operate, grasp easily; (3) one-hand operation, security performance is good; (4) simple in structure, compact, volume is little, draws materials extensively, and production cost is low, utilizes sucker base can be fixed in chopping board or wall place arbitrarily, and is very easy to use.

The utility model is widely used in various cutters.

The specific embodiment

Referring to accompanying drawing, a kind of portable knife sharpener, it mainly comprises stake body 1, top at stake body 1 side plate 13 is provided with axis hole 31, bolster 3 interts in the axis hole 31 of biside plate 13, two emery wheels 4 are laid and fixed to place's symmetry in the middle of bolster 3, one is coarse plain emery wheel 41, another is a fine grinding wheel 42, pattern 5 is established in the inboard of two emery wheels 4, pattern 5 is a sphere, a facial plane, and profile is a spherical surface body, in order to shorten the distance of each parts on the bolster 3, the plane of pattern 5 then touch the centre that is fixed on bolster 3 mutually, and the sphere of two patterns 5 is just in time proper mutually with emery wheel 4 medial surfaces, on the bolster 3 in two emery wheels, 4 outsides pattern 5 is housed in regular turn all, spring 21, nut 22 and packing ring 23.In order to strengthen stake body 1 rigidity, reach fixing quick, easy and simple to handle, be convenient for carrying, save material and reduce cost, the side plate of stake body 1 about 13 minutes two, they and stake body 1 base 11 form the U-shaped shape, and side plate 13 is designed to triangle, stake body 1 base 11 is established several vacuum cups 12, laying the quantity of sucker 12 decides on sucker 12 suction size, establish four suckers 12 in the present embodiment, sucker 12 passes behind the hole of stake body 1 base 11 movable fastening by nut 14 through the bolt on it.

Operation principle of the present utility model: four vacuum type suckers 12 that are fixed on stake body 1 base 11 by activity earlier are fixed on arbitrary position to whole knife sharpener, as are fixed on the chopping board or wall in kitchen.Then, the knife face cutting edge of a knife or a sword mouth of cutter is placed between emery wheel 4 and the pattern 5, needed grinding attitude when adjusting the control tool grinding automatically according to the sphere of pattern 5 and the angle between the emery wheel side, it is grinding angle, keep the side of knife face cutting edge of a knife or a sword mouth under the effect of spring 21, to be close to emery wheel 4 sides all the time, at this moment, hold hilt with cutter back and forth push-and-pull for several times can realize the effect of whetting a knife fast.In two emery wheels 4 in the present embodiment, one is coarse plain emery wheel 41, and another is a fine grinding wheel 42, uses coarse plain emery wheel 41 corase grind earlier, re-uses same method with fine grinding wheel 42 correct grindings, also the knife sharpener tune can be retightened once, can realize the two sides grinding of cutter fast.

Below only be preferred embodiment of the present utility model, according to above-mentioned design of the present utility model, those skilled in the art also can make various modifications and conversion to this.For example, to the modification of emery wheel, pattern, sucker and support and conversion etc.Yet similar this conversion and modification all belong to essence of the present utility model.
