Abstract

The utility model discloses a handheld blade grinder rod which comprises a holder and a grinding blade arranged on the holder. On the upper and lower parts of the grinding blade, an upper raised block and a lower raised block are positioned. When a knife is grinded, the grinding blade of the grinder rod is placed at the edge of the knife. The inclination angle can be determined with the help of the upper raised block and the lower raised block. Because the grinding angle is easily determined, the grinded knife edge will be of the same thickness.

Description

Hand-held instruments sharpenning bar

Technical field

The utility model relates to the sharpening electrician testing tool technology field, and is relevant with the structure of hand-held instruments sharpenning bar.

Background technology

As everyone knows, cutter in use for some time, blade can rust and not sharp, at this moment needs to temper.Whet a knife voluntarily for the convenience of the users, numerous businessmans have designed the multiple sharpening instrument of having produced, such as: whetstone, grinding wheel, instruments sharpenning bar or the like.

Now common instruments sharpenning bar is made up of lever 1 and the sharpening piece 2 that is assembled in lever 1 top as shown in Figure 1.During use, as shown in Figure 2, the sharpening piece 2 of instruments sharpenning bar is tilted to lean against on the blade, spur instruments sharpenning bar back and forth, can reach the effect of tempering.This instruments sharpenning bar is when whetting a knife, because have only a contact point between instruments sharpenning bar and the cutter, the angle of inclination of instruments sharpenning bar on cutter controlled by rule of thumb by the operator fully, can't form automatic location between the two, so, instruments sharpenning bar reverses on cutter when doing, and the angle of inclination is difficult to be consistent, and the blade thickness that causes grinding differs.

The inventor carries out architecture advances at the weak point of above-mentioned instruments sharpenning bar to it, and the sharpening angle is controlled easily, the blade thickness unanimity that grinds, and this case produces therefrom.

The utility model content

The purpose of this utility model is to provide a kind of hand-held instruments sharpenning bar, and the sharpening angle is controlled easily, the blade thickness unanimity that grinds.

To achieve these goals, solution of the present utility model is:

Hand-held instruments sharpenning bar is made up of lever and the sharpening piece that is assembled in the lever top, has a upper protruding block and a lower protruding block respectively at the upper/lower terminal of sharpening piece.

The upper/lower terminal of above-mentioned sharpening piece positive and negative all has a upper protruding block and a lower protruding block respectively.

Above-mentioned lever top forms framework, and the sharpening piece is embedded in the framework, and upper protruding block and lower protruding block are formed on the framework.

After adopting said structure, the utility model is owing to design a upper protruding block and a lower protruding block respectively at the upper/lower terminal of sharpening piece, so, when whetting a knife, after the sharpening piece of instruments sharpenning bar tilted to lean against on the blade, can be resisted against on the knife face by upper protruding block or lower protruding block, locate the angle of inclination, the control of sharpening angle is easy, the moving instruments sharpenning bar of pulling back again, can under the situation at angle of inclination that is consistent, implement to temper the blade thickness unanimity that order grinds.

The specific embodiment

As shown in Figure 3-4, the hand-held instruments sharpenning bar that the utility model discloses is made up of lever 1 and the sharpening piece 2 that is assembled in lever 1 top.Concrete assembling mode can form framework 11 as shown in this embodiment above lever 1, sharpening piece 2 is embedded in the framework 11.

Improvement of the present utility model is: the upper/lower terminal at sharpening piece 2 has a upper protruding block 3 and a lower protruding block 4 respectively.This embodiment is integrally formed in upper protruding block 3 and lower protruding block 4 on the framework 11.

Instruments sharpenning bar arbitrarily uses and tempers for convenience, and the upper/lower terminal of the also corresponding sharpening piece of present embodiment 2 positive and negative all has a upper protruding block 3 and a lower protruding block 4 respectively.

When the utility model is whetted a knife, shown in Fig. 5,6,7, hold after lever 1 tilts to lean against on the blade with sharpening piece 2, be resisted against on the knife face by upper protruding block 3 or lower protruding block 4, pull back again and move whole instruments sharpenning bar easily in angle of inclination, location, the control of sharpening angle, can under the situation at angle of inclination that is consistent, implement to temper the blade thickness unanimity that order grinds.Wherein, shown in Fig. 5,6, being the utility model is resisted against position on the knife face by changing lower protruding block 4, changes the angle of inclination between instruments sharpenning bar and the cutter, and control operation is very convenient.Shown in Fig. 5,7, be that the utility model is resisted against on the knife face by changing upper protruding block 3 or lower protruding block 4, come the different two sides of knife milling tool, control operation is very convenient.

Claims
