Description

Suction cup type knife sharpener

Technical field

The utility model relates to a kind of instrument of grinding blade, particularly a kind of suction cup type knife sharpener.

Background technology

Whetstone, sharpening rod iron or roller emery wheel are adopted in traditional sharpening more, use inconvenient; Chinese patent 96239439.4 disclosed ' fast knife sharpener ' is formed two-sided V-arrangement sharpening notch by two sharp seamed edges that two superimposed sharpening sheets intersect; During sharpening, the blade frame that is ground spurs blade on this V-shaped groove mouth, and the sharp seamed edge on V-shaped groove mouth both sides cuts the blade two sides that is ground, and produces new sharp knife edges, reaches the sharpening purpose.Its weak point: the one, the blade frame that is ground is when the V-shaped groove mouth, the free degree that three rotations are arranged with respect to the V-shaped groove mouth, the blade that promptly is ground can comprehensive rotation with respect to the V-shaped groove mouth and can not be located, and is difficult to guarantee that straight line draws mill, and the blade quality that grinding goes out is not good enough; Two are to use this knife sharpener to whet a knife when operation, must a hand-held knife sharpener, and another hand-held knife, thereby there is potential injury in the blade that is ground to the hand of holding knife sharpener, dangerous.The 3rd, this two-sided V-arrangement sharpening notch, can not grinding the anodontia and toothed blade of another side of one side, as steak knife.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of sucker that utilizes and is fixed in bright and clean table top, available singlehanded suction cup type knife sharpener of whetting a knife.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of suction cup type knife sharpener, its bolt and sucker are fastenedly connected and are one, and bearing is installed on the sucker by bolt; The rectangle liner of two band fillets is down in the groove that the Eight characters is placed in bearing, and the center of liner is provided with oblong aperture, and the both sides, bottom of monolithic sharpening sheet are located and assigned in the oblong aperture of left and right sides liner.Described sharpening sheet is the isosceles triangular thin type frustum of band fillet, and the big triangular facet dual-side of the isosceles of frustum is provided with sharp seamed edge, and the top of the little triangular facet of isosceles of frustum is provided with lug, nib.Angle α=30 of the sharp seamed edge in sharpening sheet both sides °-70 °, angle β=65 of sharpening sheet two sides and the big triangular facet of isosceles °-85 °.Two single face V-arrangement sharpening notches about described sharp seamed edge and the liner surface composition angle γ that is the arrangement of falling the Eight characters=15 °-35 °.

The beneficial effects of the utility model are:

Volume little, in light weight, be convenient to the collection; Being particularly suitable for family uses.

2. safe and convenient to use; Knife sharpener utilizes sucker to be fixed on the bright and clean table top, need not hand knife sharpener; Article two, sharp seamed edge each form two single face sharpening V-shaped groove mouths with liner plane, both sides, the singlehanded cutter of just can holding is with the blade frame that is ground therein on V-shaped groove mouth.The one side that is ground blade is developed the location with the plane of liner, can not swing, and has only the free degree of a rotation, can only spur the cutter that is ground along the liner plane and straight line; Be cut near the blade that is ground of sharp seamed edge one side of sharpening sheet, not only convenient, but also grind new high-quality sharp knife edges safely; The blade knife edge that is ground is the operator dorsad, has eliminated the blade that the is ground hidden danger to operator's injury.

3. ground effect is good; This monolithic sharpening sheet adopts carbide alloy, and its hard two sharp sharp seamed edges carry out grinding to the blade that is ground, and than traditional whetstone, sharpening rod iron, the ground effect of roller emery wheel and disclosed knife sharpener is better.

4. the scope of application is wide; Because two single face V-arrangement sharpening notches about knife sharpener has, when the anodontia and toothed blade of another side of one side such as grinding such as steak knife, develop the liner plane positioning with toothed one side, the operation of just can whetting a knife.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment is shown in Fig. 1-11: a kind of suction cup type knife sharpener, its bolt 4 are embedded in to be fastenedly connected in the sucker 1 of flexible plastic and with it and are one, and the screw of bearing 2 and bolt 4 are twisted and closed, bearing 2 fastening being installed on the sucker 1.The rectangle liner 5 of two band fillets is down in the groove that the Eight characters is placed in bearing 2, and the center of liner 5 is provided with oblong aperture 9, and the both sides, bottom of monolithic carbide alloy sharpening sheet 3 are located and assigned in the oblong aperture 9 of left and right sides liner 5, and integral body is packed in bearing 2 grooves.Carbide alloy sharpening sheet 3 is the isosceles triangular thin type frustum of band fillet, and the big triangular facet of the isosceles of frustum is smooth plane, and the big triangular facet dual-side of isosceles is provided with sharp seamed edge 8, angle α=50 of the sharp seamed edge 8 in both sides °; Carbide alloy sharpening sheet 3 two sides are not vertical with the big triangular facet of isosceles, and angle β=75 of forming with the big triangular facet of isosceles ° form the isosceles little triangular facet parallel with the big triangular facet of isosceles; The top of the little triangular facet of isosceles is provided with lug, nib 6, just in time sharpening sheet 3 is clamped in the notch of bearing 2, can not deviate from voluntarily.Two single face V-arrangement sharpening notches about the sharp seamed edge 8 of carbide alloy sharpening sheet 3 dual-sides and the liner 5 surface composition angle γ that are the arrangement of falling the Eight characters=30 °.

During sharpening, utilize sucker that knife sharpener is fixedly positioning on bright and clean table top, need not hand knife sharpener, the singlehanded cutter of just can holding therein on V-shaped groove mouth, back and forth spurs the blade frame that is ground and whets a knife.The one side that is ground blade is developed the location with the plane of liner 5, can not swing the cutter that can only be ground along the plane and straight line pulling of liner 5; Be cut near the blade that is ground of sharp seamed edge one side of sharpening sheet, not only convenient, but also grind new high-quality sharp knife edges safely.Because two single face V-arrangement sharpening notches about knife sharpener has, thus but grinding such as steak knife etc. are simultaneously anodontia the toothed blade of another side.
