Abstract
The utility model discloses a multipurpose knife grinder, which is composed of a bolt, a shaft sleeve arranged on one end of the bolt, a handgrip, a grinding wheel and a supporting wheel which are fixed on the bolt and regulating wheels arranged on both ends of the supporting wheel. The outer walls of the regulating wheels are dentate; the diameter of the addendum circle is equal to the diameter of the grinding wheel; round benches outwards bulge on the central positions of the external sides of the regulating wheels; bolt holes of the centers of the regulating wheels extend to the tops of the round benches.
Description
The utility model relates to a kind of improved family expenses knife sharpener.
Existing knife sharpener needs knife sharpener is placed on the plane when using, and then cutter is inserted between support wheel and the emery wheel, and front and back promote cutter, knife sharpener is whetted a knife at plane rolling, thereby exist following problems:
One, various cutter hub thickness differences, purposes difference, sharpening angle also have nothing in common with each other, angle wanted big when the knife back became 5 degree angles to be best angle, mill chopper when sharpening a kitchen knife with emery wheel, existing knife sharpener sharpening angle can not be adjusted, and can not satisfy the requirement of tempering the required best angle of various cutters.
Two, because knife sharpener must be placed on the plane and use, therefore tempering of special tool is restricted, can't uses as reaping hook, scissors.
The purpose of this utility model provides a kind ofly improvedly uses knife sharpener more, and this knife sharpener angle can be adjusted, and can satisfy and temper the required best angle of various cutters, possesses multiple using method, can temper multiple cutter.
The purpose of this utility model can reach by following measure: the gap that adjustment wheel, change adjustment wheel and emery wheel are housed on knife sharpener can change the sharpening angle.At an end of screw the handle of axle sleeve and class prismoid is housed, can keeps cutter motionless during sharpening, promote knife sharpener and whet a knife, therefore can temper multiple cutter.Adjust wheel for covering shape, outer wall is a dentation, and wall is tall and big in 4 millimeters, and the position thickness that is connected with screw is greater than 4 millimeters, (the screw degree of depth), at adjustment wheel outer side center position a round platform that outwards protrudes is arranged, the screw of adjusting the wheel center extends to the round platform top, and adjustment wheel internal thread diameter is less than screw diameter, adjust the wheel internal diameter less than the support wheel diameter, grinding wheel diameter is equal to or greater than adjusts the wheel tip diameter, and axle sleeve and handle are stationary fit, with screw for movingly.
The structure that the utility model only need change knife sharpener can reach the purpose of adjusting the sharpening angle, with the screw lengthening, increases an axle sleeve and handle and just can play the effect of using more, so simple in structure, cost is low.
The drawing of accompanying drawing is described as follows:
Fig. 1 is many profiles with knife sharpener.
Fig. 2 is a left view.
Fig. 3, Fig. 4 are to use state diagram.
The utility model is described in further detail below in conjunction with Fig. 1 embodiment.
The knife sharpeners of using are made up of adjustment wheel ［ 1 ］, support wheel ［ 2 ］, emery wheel ［ 3 ］, screw ［ 4 ］, nut ［ 5 ］, handle ［ 6 ］, axle sleeve ［ 7 ］ more.
Adjusting wheel ［ 1 ］ is made by plastics or metal, be the lid shape, outer wall is a dentation, can play the effect that prevents the hand cunning when adjusting the sharpening angle and use the increase friction on the plane, for being used, emery wheel wears up to minimum thickness, adjusting wheel wall height should be greater than 4 millimeter, if take turns with plastics manufacturing adjustment, the position that the adjustment wheel is connected with screw during because of sharpening will be subjected to certain power, this position thickness low LCL will produce strain, the sharpening angle is changed, therefore the thickness at this position should be adjusted wheel outer side center position greater than 4 millimeters (screw length) a round platform that outwards protrudes, the screw of adjusting the wheel center extends to the round platform top, round platform top and screw head leave certain clearance during installation, adjust wheel and move right, screw can not eject, and can play the effect of taking turns with the screw bond sites of adjusting of thickening.Adjustment wheel and screw, support wheel rotate synchronously when whetting a knife for assurance, adjust between wheel and screw, the support wheel and should have certain frictional resistance, adjusting the wheel internal thread diameter should be less than screw diameter, adjust elasticity banding screw and support wheel that the wheel internal diameter utilizes plastics after less than support wheel diameter, assembling, reach this purpose.Adjusting word and the direction of rotation arrow that the wheel outside indicates adjustment sharpening angular dimension.See Fig. 2.For material-saving and can meet the requirements of intensity, be provided with reinforcement adjusting the wheel the inside, the triangle that whole wheel the inside, Fig. 1 left side is made of dotted line is a reinforcement, also can be round table-like.
Support wheel ［ 2 ］ is made with metallic plate, for round table-like, the round platform bottom is a tubular, and diameter is more than or equal to adjusting the wheel internal diameter, there is a circular hole in bottom center, and adjusting wheel, support wheel and emery wheel during by screw, nut clamping support wheel, emery wheel, sharpening is that axle is with rotating with the screw.
Emery wheel ［ 3 ］ is made with diamond dust, for cylindric, grinding wheel diameter approximates adjusts the wheel tip diameter, the emery wheel coefficient of friction is bigger, when using in the plane, emery wheel with adjust the wheel increment all with plane contact, can prevent from that knife sharpener from rolling to skid, the emery wheel centre is the concavity that matches with the support wheel round platform, and a circular hole is arranged.
Handle ［ 6 ］ is made with timber or plastics, similar cylinder, and there is a circular hole in handle center, if handle is selected the timber manufacturing for use, can adopt blind hole, inlays axle sleeve in the hole, uses in the plane if family only need temper the kitchen knife class, handle can be taken off.
Axle sleeve ［ 7 ］ is made with plastics or metal, is cylindrical tube, with handle be stationary fit, with screw for movingly.
When adjusting the sharpening angle, pinch emery wheel on the other hand, the another hand pinches adjusts wheel, go up the big or small direction of rotation arrow application of force of sign according to the adjustment wheel and rotate the adjustment wheel, make to adjust to take turns and relatively rotate with screw support crop rotation, move to the left or to the right along the screw support wheel, change to adjust the gap between wheel and the emery wheel, can reach the purpose of adjusting the sharpening angle, when sharpening a kitchen knife emery wheel with adjust 3 millimeters in wheel gap for best.
Using method is seen Fig. 4.
During sharpening, blade up, knife sharpener is placed on the blade top, blade is inserted between support wheel and the emery wheel, the one side of cutter leans against to be adjusted on the wheel, and the blade on opposite leans against on the emery wheel, and the angle of cutter and emery wheel is maintained fixed, the hand-held knife handle, another holds the sharpening handle, and front and back promote knife sharpener, makes emery wheel support wheel and adjustment wheel rotate and can whet a knife, also can one hold the knife sharpener handle, knife sharpener is erected another hand-held knife handle, and blade is to being placed down on the knife sharpener, and front and back promote cutter, make knife sharpener rotate into sharpening, if temper the kitchen knife class, also knife sharpener can be placed on the plane, then cutter is placed on the knife sharpener, front and back promote cutter, knife sharpener is rolled in the plane whet a knife.(see figure 3)
