Abstract

The hand knife sharpener with fixed angle between the whetstone and the knife has fixture to fix the knife edge. The steel wire is made to penetrate through the positioning holes on two sides of the fixture to determine the sharpening angle. The positioning holes and the edge line define one plane and the whetstone moves always in this plane, so as to ensure the sharpened edge is in the plane. Grasping the whetstone to move reciprocally can grind the knife edge into plane.

Description

The fixed angle knife sharpener

Technical field

The invention belongs to a kind of manual knife sharpening device, can allow cutter obtain the polishing effect of specialty.

Background technology

The present invention relates to metal and plastic processing technology.

Summary of the invention

Owing to use traditional whetstone directly to whet a knife, can be because the user be firmly uneven, and make blade the surface of arc occur, influence the cutting effect of blade.In order to overcome the problems referred to above, the present invention allows whetstone and blade remain same angle, makes the blade surface that grinds remain a plane (almost plane), keeps the cutting effect of blade.

The technical scheme that the present invention deals with problems is, uses anchor clamps to fix cutter, is equipped with some holes on the anchor clamps; Use steel-wire track to be connected with whetstone, form straight line, guide rail one end is passed hole on the anchor clamps, the while whetstone is close to blade.According to the principle of 2 definite straight lines, the blade of this moment and remains certain angle between the whetstone, and the user holds whetstone and does and move back and forth, and just can polish satisfactory plane blade.Because among the present invention, the edge length of the cutter that is suitable for has certain limitation, therefore, guide rail and whetstone move left and right, and the angular error that produces can be ignored substantially, has so just realized polishing the effect of plane blade.

Description of drawings

Below in conjunction with design drawing of the present invention and example, further specify the present invention.

Fig. 1 is the installation diagram of knife sharpener anchor clamps.

Fig. 2 is the connection layout of whetstone and guide rail.

Fig. 3 is the installation diagram of whetstone.

Fig. 4 is the sharpening schematic diagram of whetstone.

Fig. 5 is the C-clamp schematic diagram.

Fig. 6 is with C type clip that knife sharpener is fixing on the table.

Fig. 7 is the three-view diagram of knife sharpener anchor clamps.

Fig. 8 is the three-view diagram of whetstone.

Two of 1. knife sharpeners intermediate plates among the figure; 2. the locating hole of different angles on the knife sharpener; 3. the holding screw of knife sharpener anchor clamps; 4. the set screw of knife sharpener anchor clamps; 5. the guide rail of whetstone; 6. whetstone; 7. connecting screw; 8.C clevis; 9. open-work; 10. treat knife milling tool; 11. desktop.

In Fig. 1, unscrew the set screw of 4 knife sharpener anchor clamps, determine width roughly between the intermediate plate, so that put into cutter.Put into after the cutter, tighten 3 holding screws, cutter is fixed on the anchor clamps.

In Fig. 2, unscrew 7 connecting screws, with the aperture on the guide rail one end insertion whetstone, tighten connecting screw then, whetstone and guide rail are linked into an integrated entity.

In Fig. 3, the location sky with on the guide rail other end insertion anchor clamps is placed on whetstone on the blade.

In Fig. 4, according to the order of ABCDE, mobile whetstone.Because whetstone moves in the plane that blade and locating hole are determined all the time, this moment, whetstone and the residing angle of blade were identical always, and therefore the blade that polish is the plane blade, has guaranteed the cutting power of blade.

Among Fig. 5, show the schematic diagram of 8C clevis.

Among Fig. 6,,, pass 9 open-works at anchor clamps center simultaneously the cylinder of 8C clevis upper end with sub-stuck-at-1 desktop of 8C clevis.

In Fig. 7, drawn the three-view diagram of two intermediate plates of knife sharpener.

In Fig. 8, drawn the three-view diagram of knife sharpener whetstone, whetstone can use the oilstone of various different models, to satisfy different polishing requirements.

The specific embodiment

According to drawing, process the knife sharpener anchor clamps by Metal Processing Factory.Make parts of plastics on the whetstone by drawing, use super glue that the grinding stone of different model is adhered on the parts of plastics, carry out whetstone.

Claims

1. a knife sharpener is characterized in that using the anchor clamps fixed cutting tool, uses the fixing angle between whetstone and blade of hole on steel-wire track and the anchor clamps.

2. knife sharpener according to claim 1 is characterized in that the both sides of anchor clamps have the hole of fixed-site.Steel-wire track passes hole, and the straight line that whetstone and steel-wire track are constituted is parallel to the plane that hole and blade form, almost plane all the time.

3. knife sharpener according to claim 1 is characterized in that anchor clamps use two screws to fix.

4. knife sharpener according to claim 1 is characterized in that the outer bread one deck duroplasts of whetstone, is convenient to the user and holds.

5. knife sharpener according to claim 1 is characterized in that and can knife sharpener be fixed in desktop with a C type clip.
