A front plate and a rear plate are fixed on the base frame, a rotating shaft is arranged between the upper parts of the front plate and the rear plate, the grinding wheel is fixedly mounted at the middle part of the rotating shaft, the front fixing knife wheel and the rear fixing knife wheel are fixedly mounted on the rotating shafts on the two sides of the grinding wheel respectively, and the inner sides of the front fixing knife wheel and the rear fixing knife wheel form a conical body, a gap which has a narrow lower part and a wide upper part and can hold knife edge is formed between the inner sides of the front fixing knife wheel and the rear fixing knife wheel and the grinding wheel, The knife sharpening wheel has a simple structure and convenient use, and can sharpen a knife through the gap which has a narrow lower part and a wide upper part and is formed bythe inner sides of the front knife fixing wheel and the rear knife fixing wheel and the grinding wheel as well as can the hold knife edge, so as to greatly improve work efficiency. The knife sharpening wheel arranges a hand guard rack to avoid the hand injury during knife sharpening, so as to reduce the potential safety hazard during the knife sharpening.

Description

Safe grinding wheel

Technical field

The utility model relates to a kind of grinding wheel, especially a kind of safe grinding wheel.

Background technology

At present, the instrument that family whets a knife generally adopts knifeboard, instruments sharpenning bar etc., but the knifeboard sharpening time is long, and will have certain skill could be with the cutter milled; And instruments sharpenning bar is bad firmly, the weak effect of therefore whetting a knife, in sum, existing sharpening instrument exist sharpening efficient low, easily hinder hand when whetting a knife and have the problem of potential safety hazard.

Summary of the invention

The utility model provides a kind of safe knife sharpening wheel, has overcome the deficiency of above-mentioned prior art, its can solve existing sharpening instrument sharpening efficient low, easily hinder hand when whetting a knife and have security hidden trouble.

The technical solution of the utility model is achieved like this: safe knife sharpening wheel comprises underframe, emery wheel, front solid break bar and rear solid break bar; Be fixed with front and rear panels at underframe, the rotating shaft that can rotate is installed between the top of front and rear panels, middle part in rotating shaft is installed with emery wheel, rotating shaft in the emery wheel both sides is installed with front solid break bar and rear solid break bar, the inboard of front solid break bar and rear solid break bar be mutual correspondence taper and and emery wheel between form the lower narrow wide and gap that can place blade.

Two hand-protecting supports are arranged on the underframe on above-mentioned emery wheel right side, and each hand-protecting support comprises front finger guard and rear finger guard, and front finger guard and rear finger guard are fixedly mounted on the underframe from A-P, forms the feed passage corresponding with the gap between front finger guard and the rear finger guard.

There is the chute of mutual correspondence the inboard of above-mentioned underframe bottom, and the slide plate that can move along chute is installed in chute.

On the above-mentioned front and rear panels handle is installed.

The utility model is simple in structure, and is easy to use, form lower narrow gap wide and that can place blade between inboard that can be by front solid break bar and rear solid break bar and the emery wheel and whet a knife, so operating efficiency is greatly improved; Owing to be provided with hand-protecting support, avoid when whetting a knife blade to hinder hand, therefore reduced the potential safety hazard that exists when whetting a knife.

Description of drawings

Fig. 1 is main TV structure figure of the present utility model.

Fig. 2 is the plan structure figure of Fig. 1.

Fig. 3 is the left TV structure figure of Fig. 1.

Coding among the figure is respectively: 1 is underframe, and 2 is emery wheel, and 3 is front solid break bar, and 4 is rear solid break bar, and 5 is header board, and 6 is rear plate, and 7 are rotating shaft, and 8 is handle, and 9 is the gap, and 10 is front finger guard, and 11 is rear finger guard, and 12 are the feed passage, and 13 is slide plate.

The specific embodiment

As shown in Figure 1, 2, 3, safe grinding wheel comprises underframe 1, emery wheel 2, preceding solid break bar 3 and back break bar 4 admittedly; On underframe 1, be fixed with header board 5 and back plate 6, between the top of header board 5 and back plate 6, the rotating shaft 7 that can rotate is installed, be installed with emery wheel 2 at the middle part of rotating shaft 7, break bar 4 is consolidated in solid break bar 3 and back before being installed with in the rotating shaft 7 of emery wheel 2 both sides, before solid break bar 3 and back admittedly the inboard of break bar 4 be mutual correspondence taper and and emery wheel 2 between form the narrow down gap 9 wide and that can place blade of, like this, when need whetting a knife, blade is placed on to twitch back and forth in the gap 9 just cutter can have been ground.

As shown in Figure 1, 2, 3, two handguard framves are arranged on the underframe 1 on emery wheel right side, finger guard 10 and back finger guard 11 before each handguard frame comprises, preceding finger guard 10 and back finger guard 11 are fixedly mounted on the underframe 1 from A-P, form and gap 9 corresponding feed passages 12 between preceding finger guard 10 and the back finger guard 11, in use, blade is placed in the feed passage 12, when twitching blade back and forth, blade move left and right and can not hurt hand in feed passage 12, thereby just reduced potential safety hazard.

As shown in Figure 1, 2, 3, there is the chute of mutual correspondence the inboard of underframe 1 bottom, and the slide plate 13 that can move along chute is installed in chute, and like this, blade is ground the bits that produce later and can stay on the slide plate 13, regularly slide plate 13 is taken out to remove bits and get final product.

As shown in Figure 1, 2, 3, on header board 5 and the rear plate 6 handle 8 is installed, like this, when whetting a knife, can fixes with hand grip handle 8 underframe 1, keep the stability of underframe 1, reduced potential safety hazard.
