Abstract

The utility model discloses a knife sharpener with a variable grinding included angle, which comprises two sets of circular carbide blades, blade shafts and supports. The utility model is characterized in that the shaft of one set of circular carbide blades is stationarily fixed on a fixed support, and the two ends of the shaft of the other set of circular carbide blades pass through holes at the tail ends of two cantilevers of a movable support firstly, and then pass through a transverse strip-shaped hole on the fixed support; the cross beam of the movable support is connected with a bolt by a hole arranged at the middle part of the cross beam, and the other end of the bolt passes through a nut arranged on the fixed support, wherein one end of the bolt is provided with a round topper, and the other end of the bolt is provided with an adjustable lever. When the bolt is rotated, because the nut does not move, the bolt can reciprocate so as to drive the movable support and a set of blades to move along the strip-shaped hole, then the relative positions of the two blades are changed, namely, the included angle formed by the intersection of the two blades is changed. The utility model has the advantages that: the grinding angle of the knife sharpener can be changed through a simple operation so as to sharpen various cutters.

Description

The knife sharpener of variable grinding angle

Affiliated technical field

The utility model relates to knife sharpener, especially a kind of knife sharpener of variable grinding angle.

Background technology

A kind of knife sharpener of traditional form has two groups of circular alloy grinding blades.These two groups of blades intersect formation one angle.The edge of a knife is ground by dragging back and forth on angle, and final edge of a knife angle is consistent with the blade angle, whets a knife promptly to accuse and finishes.A problem is arranged here: various cuttves are because of purposes difference variable thickness, blade angle difference.Such as the cutter of cutting bone and meat cutting, blade angle can differ several times; Kitchen knife and fruit knife difference also arranged.And knife sharpener has only a fixed angle, can't grind the cutter of different blade angles.

Summary of the invention

Fix for solving conventional alloys knife sharpener cutting edge angle, can't adapt to the shortcoming of the different cutter of blade angle, the utility model provides a kind of knife sharpener of variable grinding angle of energy head it off.

The utility model addresses the above problem the technical scheme of taking: the knife sharpener of variable grinding angle, form by two groups of circular alloy blades and blade shaft, support, it is characterized in that: wherein the axle of one group of blade maintains static on fixed support, the axle two ends of another group blade pass one earlier, and [the horizontal bar hole on the fixed support is passed in the hole of shape travel(l)ing rest two cantilevered distal end again.[shape travel(l)ing rest transverse arm is through a hole of centre, and with an end band rounded tabs, an end has the bolt of adjusting rod to link to each other.The bolt other end passes the nut on the fixed support.When bolt during by turn, nut maintains static, and bolt then can move back and forth, and [shape travel(l)ing rest and one group of blade move along bar hole thereby drive.Two groups of blade relative positions change, and have promptly changed them and have intersected the angle that forms.

The beneficial effects of the utility model are: can change the knife sharpener grinding angle by simple operations, grind the cutter of sharp various different blade angles.

Description of drawings

Fig. 1 is the knife sharpener side view of variable grinding angle.Fig. 2 is that A is to view.

The specific embodiment

As shown in the figure, on the knife sharpener seat 1, the axle 4 of set of blades 2 maintains static, and the axle 5 of set of blades 3 passes [hole on 6 liang of cantilevers of shape travel(l)ing rest and the horizontal bar hole 7 on the support 1.Bolt 8 passes that [transverse arm is clamped in the hole in the middle of shape travel(l)ing rest 6 transverse arms, and one rounded tabs 9 greater than the aperture is respectively arranged on the both sides, hole.The bolt other end revolved the nut 10 that is fixed on the knife sharpener seat 1, and in the end adjusting rod 11 was arranged.Hand is twisted adjusting rod, because nut maintains static, bolt promptly moves back and forth, and by [the shape travel(l)ing rest, advancing or retreat in drive set of blades 3 edges laterally bar hole, intersects the angle that forms and change two groups of blades, to adapt to the cutter of different blade angles.

Claims

1. the knife sharpener of variable grinding angle, form by two groups of circular alloy blades and blade shaft, support, it is characterized in that: wherein the axle of one group of blade maintains static on fixed support, the hole of a travel(l)ing rest two cantilevered distal end is passed at the axle two ends of another group blade earlier, pass the horizontal bar hole on the fixed support again, the travel(l)ing rest transverse arm is through a hole of centre, with an end band rounded tabs, one end has the bolt of adjusting rod to link to each other, and the bolt other end passes the nut on the fixed support.
