Abstract

The utility model discloses a pencil sharpener, belonging to a device for sharpening pencils provided with pencil cores. The pencil sharpener comprises a cutting blade and a cutting seat body. The middle part of the cutting seat body is provided with a chip leaking slot, and a slope arranged inside the chip leaking slot is provided with the cutting blade by screws; the lower part of the chip leaking slot is provided with a chip storing chamber provided with a movable inserting plate, and the working panel of the cutting seat body is provided with a guide slot with a semicircular cross section. When used, the pencil sharpener is pressed tightly by one hand, and a pencil is held by the other hand, so that the pencil is forced to do reciprocating movement on the guide slot of the cutting seat body to cut the pencil well. The pencil sharpener cuts pencils without breaking pencil cores, and enhances the utilization ratio of the pencils with pencil cores. The utility model has simple structure, easy fabrication, and safe utilization.

Description

Pencil-sharpening device

The utility model belongs to cuts the device, particularly pencil-sharpening device of repairing the pen that has pen core.

Current, cutting the pen of repairing the band pen core has and uses pocket knife, though convenient, security is lower, easily damages in the use, and particularly the pupil grasps the ability of pocket knife, can't use pocket knife to cut and repair qualified pencil.The substitute is present widely used pencil sharpener, can cut safe ready and repair pencil, but the knife edge of pencil sharpener is sharp inadequately, service time, the rimmer knife cutting edge of a knife or a sword was blunt old slightly, rotate the intensity of the torsion of tangent plane that pencil lead bears in the use greater than lead for retractable pencil itself, when sharpening a pencil, disconnected while sharpening a pencil, cause waste bigger.

The purpose of this utility model is to provide a kind of pencil-sharpening device, has avoided pencil to rotate the torsion that lead for retractable pencil bore when sharpening a pencil, and makes into to move back and forth cutting, makes pen core be difficult for cutting disconnected, has improved the utilization rate of the pen that has pen core.

The utility model is achieved in that a kind of pencil-sharpening device, comprise blade and tool post, be provided with Lou bits groove at the middle part of tool post, by screw blade is installed on the inclined-plane in leaking the bits groove, the storage bits chamber that has active plugboard is being set in the bottom of leaking the bits groove, the dual-side of bottom, storage bits chamber is provided with the chute that matches with the dual-side of active plugboard, and the longitudinal center line of the working face of tool post is provided with the gathering sill that cross section is half garden shape.

When the utility model uses, on the other hand by tight pencil-sharpening device, hold a pen on the other hand pen is become about 10 ° approximately with the working face of tool post, make in the gathering sill of the tip of the brushstyle of a writing or painting on the working face of the tool post at leakage bits groove place and move back and forth with blade, a hand-held limit chamfered edge changes, and can will please correct, and the wood chip under the bits falls into storage bits chamber, wood chip therefrom can be discharged when twitching active plugboard, this pencil-sharpening device is suitable for the various types of wooden pens of outsourcing that have pen core of row.Pencil sharpener is simple in structure, and is easy to manufacture, and traditional rotation is sharpened a pencil, and becomes to move back and forth to sharpen a pencil, and makes pen core be difficult for cutting disconnected, improved the utilization rate of pen, cuts the waste, and can cut out the penholder pen core of different length and angle shape as required.

Fig. 1 is a front view of the present utility model, and Fig. 2 is an A-A cutaway view of the present utility model, and Fig. 3 is the utility model B-B cutaway view, and Fig. 4 is the structural representation of blade.The utility model will be further described below in conjunction with accompanying drawing, a kind of pencil-sharpening device, comprise blade 3. with tool post 1., be provided with Lou the bits groove at tool post middle part 1. 2., on leaking the inclined-plane of bits groove in 2., 7. blade is installed 3. by screw, be provided with and having active plugboard storage bits chamber 6. 5. leaking bits groove bottom 2., the storage bits chamber 5. dual-side of bottom is provided with the chute that matches with active plugboard dual-side 6., the longitudinal center line of tool post working face 1. be provided with cross section be half garden shape gathering sill 4., tool post profile 1. can be a cuboid, the blade 3. installation at center can be a slotted hole, it also can be shape hole, garden, 3. blade is the single face sword, blade leakage bits groove inclined-plane 2. 3. is installed is become 30 °-60 ° angle with horizontal plane.
