Description

Angle gauge

Technical Field

The invention relates to an angle gauge, in particular to a multi-angle gauge for grinding a knife edge.

Background

People can use various cutters in a large amount in life and work, the cutters are long in service time, and the cutting edges are easy to wear and dull. At this moment, people often can dull the knife edge, and the traditional knife edge needs to be accumulated for a long time to grasp a certain angle of the knife edge, so as to ensure that the knife edge is sharpened. The mastering of the sharpening angle requires experience and is not easy to master.

In response to the above problems, there are two products in current practice: the first is a product of pressing from both sides on the back of a knife, and its product one side is used for placing the finger, and the another side is fixed between the another side of sword and whetstone, plays the effect of fixed sharpening angle when the sharpening, and the shortcoming of this kind of product lies in, and sharpening angle is only unique, and a product only is suitable for the wide cutter of a face to grind the cutting edge, and the wide cutter of other different faces probably can't obtain a suitable angle of whetting a knife through using this product, causes the sharpening angle inaccurate to the effect that the cutting edge was ground in the influence. Secondly, a wedge maintains the sharpening angle through the inclined surface, the product is also the only sharpening angle, one product is only suitable for sharpening the blade by a cutter with one angle, the product is not skid-proof, and the wedge is frequently moved in the sharpening process to cause the sharpening angle to change and influence the sharpening blade.

Disclosure of Invention

The invention aims to provide an angle gauge, which mainly solves the technical problems in the prior art, provides a plurality of sharpening angles through two or more inclined planes at the top, can be used for sharpening blades of cutters with different widths, and has the advantages of small and exquisite structure, convenience in use, portability and the like.

In order to achieve the purpose, the invention adopts the technical scheme that:

an angle gauge, characterized by: it comprises a top part, a bottom part with a horizontal support below the top part; the top be formed by two or more than two inclined planes concatenation, the inclination on inclined plane includes two different angles at least, the inclined plane lower extreme is connected with bottom outward flange.

In view of the above technical features, the present invention has the following advantages:

1. one angle gauge is provided with two or more inclined planes, and the inclined angles of the inclined planes are different, so that the angle requirement of cutters with different cutter face widths when grinding the cutting edge can be met;

2. the angle gauge plays the initial positioning effect, and certain sharpening angle is confirmed by the inclined plane of angle gauge to the sword of taking, then at sharpening in-process, the cutter is through keeping this angle the knife edge of grinding on metal whetting a knife base member or other whetstones, ensures that the knife edge can obtain good grinding effect. The finger can be placed on other inclined planes except the positioning inclined plane actually used when the grinding blade is started, so that the pressing is convenient, the anti-skidding effect of the angle gauge and the metal grinding base body or other grinding stones can be enhanced, and the finger safety can be protected under the condition that the finger keeps a certain distance from the inclined plane actually used when the grinding blade is ground.

3. The inclined plane lower extreme is connected with the bottom outward flange, and the bottom outward flange is arc transitional coupling, can prevent fish tail finger or other article, makes the angle gauge whole pleasing to the eye simultaneously.

Further, the top and the bottom are integrally formed or connected in an adhering mode or fixedly connected through screws.

Furthermore, the bottom has an indent portion, and the indent portion has a reinforcing rib, and the reinforcing rib connects the bottom and the edge of the groove.

In view of the above technical features, the present invention has the following advantages: the bottom is hollowed out by the concave part in the bottom, the bottom and the groove are fixed by the reinforcing ribs, materials can be saved, the weight of the angle gauge is reduced, and cost is saved.

Further, the groove is provided with a magnet or an anti-skid component, and the depth of the groove inner placing surface is the same as the thickness of the magnet or the anti-skid component.

1. the bottom of the groove is hollowed, the reinforcing ribs reinforce the connection and fixation of the groove and the bottom, and meanwhile, when the groove is provided with the magnet or the anti-skid part in a sticking mode, the hollowed-out part increases the adhesive force between the groove and the magnet or the anti-skid part by increasing the adhesive area. The magnet of installation can increase the adhesive force between angle gauge and the metal base member of whetting a knife in the recess, and the installation antiskid unit can increase the adhesive force between angle gauge and other base members of whetting a knife in the recess, and the band edge instrument of being convenient for is with the help of the angle gauge to confirm the sharpening angle when sharpening begins, prevents that the angle gauge from sliding. Meanwhile, the bottom of the groove is hollowed, so that the material and cost are saved.

2. The depth of the groove is the same as the thickness of the magnet or the anti-slip part, so that after the magnet or the anti-slip part is installed in the groove, the magnet or the anti-slip part is located on the same plane, and the angle gauge can be stably placed on a grinding stone or other base bodies.

It should be noted that, although the top inclined plane provided by the present invention is four-sided, other inclined planes capable of achieving the same function, such as two-sided, three-sided, five-sided, six-sided, etc., are also covered by the present invention.

According to the technical scheme provided by the invention, different sizes can be designed according to actual conditions so as to meet the requirements of sharpening different cutters, and one angle gauge meets the requirements of sharpening a plurality of face-width cutters.
