Abstract
The utility model discloses a pencil sharpener for cutting pencils, comprising a sharpener body, a knife blade, a pressing plate and screws. Taper holes which are used for sharpening a pencil are arranged on the sharpener body and are compounded of two cones whose two cone angles are unequal. The purpose of the utility model is to overcome the phenomenon that a lead cord is broken because the sharpener is not matched with the pencil due to the unequal diameter of the lead cord and a penholder. In order to make a knife blade with combined cutting edges with no straight knife, the utility model adopts a sheet-shaped knife blade which provides finite toughness and is capable of being folded. Under the action of the pressing plate whose generating line shape is inosculated with the combined taper hole, the sheet-shaped knife blade is capable of being folded into a combined cutting edge. So the success ratio of sharpening a pencil is enhanced.
Description
The utility model belongs to improved pencil sharpener.Existing pencil sharpener mainly is made up of a cutter hub and a blade that has taper hole.No matter therefore this pencil sharpener, all have certain market demand owing to simple in structure, with low cost aspect production and selling.But the blade of this straight sword is when the rotary cut pencil, and because of penholder, lead core diameter do not wait, the resistance to cutting that is produced does not match, and lead for retractable pencil easily takes place cut disconnected phenomenon, and this is the weak point of existing pencil-knife.
The utility model is the disconnected core problem when solving the rotary cut pencil, proposes a kind of improved structure.1 is screw in the Figure of description, 2 is pressing plate, 3 is blade, 4 is cutter hub, the taper hole that the rotary cut pencil is used on the cutter hub is to be composited by the awl that two cone angles do not wait, and big cone angle is 11 ° to 15 °, and small-angle is 5 ° to 7 °, adorn now the blade of the compound sword that matches with its bus and have on the bus of this compound taper hole, in order to cut.Then can overcome disconnected core phenomenon.For satisfied requirement with compound angle of throat sheet, but the blade material requirement is the toughness that certain backfin is arranged.For the convenience of manufacture craft with reduce the cost of pencil sharpener as far as possible.The utility model adopts commercially available " double-edged razor blade " or used double-edged razor blade, all can reach above-mentioned effect.Have certain toughness because of double-edged razor blade is thin, can under certain pressure, be out of shape and continuous.In order to guarantee to form the compound sword that requires after blade is installed on cutter hub, the bottom shape of pressing plate 2 should coincide with the shape of cutter hub end face.Profile as shown in Figure of description, blade 3 has been converted into the blade with combined cut sword under the pressuring action of pressing plate 2 and screw 1, because there is sword on the double-edged razor blade two sides, so can be with two compound taper holes of system on cutter hub, to increase the result of use of pencil sharpener.It is opposite to notice when cutting lead that a direction is revolved in two holes, i.e. inverse time, a up time.But effect is the same.
Claims (2)
1, the utility model is a kind of cutter of rotary cut pencil, mainly form by blade, cutter hub, pressing plate etc., it is characterized in that but blade has toughness and two cutting edges of backfin, two bipyramid holes are arranged on the cutter hub, its face and pressing plate bottom surface that blade is installed is a folding face that matches.
2, according to the cutter of the described rotary cut pencil of claim 1, it is characterized in that the taper hole on the cutter hub is to be composited by the bipyramid hole that two cone angles do not wait, wherein the auger orifice angle is 11 °---15 °, the conelet orifice angle is 5 °---7 °.
