Description

Semiautomatic pencil sharpener

At present, the propelling pencil cutter on known market structure is that shell, card pen clip, extension spring, pencil are twisted, travelling gear, hand or electronic Propelling pencil with sharpener in cap twist and cut pencil.Twist with mechanism's Propelling pencil with sharpener in cap, chuck is clamped pencil and is finished the process that sharpens a pencil, and be the easily broken lead of cross cutting pencil, and the volume of propelling pencil cutter is bigger.

The purpose of this utility model provides a kind of cutter that sharpens a pencil, and it is powers and functions planings pencil not, and volume little, be easy to carry, practical and convenient.

The purpose of this utility model is to realize like this, it is by flashboard in the plastic casing fixedly toy motor, battery, and on the nylon square tool post, knife rest is fixed on motor shaft head with jackscrew to two leaf blades with the screw relative fixed, but blade exposes at leveling board square opening place, and adjustable size.Starter motor, the purpose of high speed rotation of blade planing pencil.

In a rectangle plastics shell, two flashboards block a toy motor in one of the fillet, the motor shaft head jackscrew is fixed a square nylon knife rest, the intrinsic relatively two leaf blades of knife rest screw, but blade is exposed by a leveling board square opening place at place, rectangle shell one ladder plane.The shell other end is adorned three pieces of 1.5V No.5 cells and is powered to motor.But leveling board one end moves there to be two protrusion heads to serve as that axle is upper and lower, and blade just exposes changeable on dull and stereotyped mouth, just sharpens a pencil to the size of cutter, and the speed that decision sharpens a pencil is controlled by handwheel.A transparent plastic guard shield is established in the blade top, is fixed on the shell limit.Pencil can activity in cover, prevents to cut hand and pencil and flies up and be as the criterion.Establish drawer type plastics in the blade lower casing and contain pen bits box.

The pencil pen core loading angle of forward planing is little not easily broken, and cross cutting pen core loading angle is easily broken greatly, and the former volume is also less.

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

Figure one is the shell front view; Figure two is shell vertical views; Figure three is shell left views; Figure four is treadmill master maps; Figure five is treadmill vertical views; Figure six is handwheels.

1. switch mouths among the figure; 2. handwheel mouth; 3. guard shield; 4. battery case; 5. motor position; 6. protrude a jack; 7. handwheel fixed head; 8. crumbs box mouth; 9., 10. stretch the pencil finger notch; 11. dull and stereotyped handwheel lifting nut; 12. blade square opening; 13. two protrude head; 14. dull and stereotyped handwheel.

Enforcement figure handwheel (14) is screwed in the handwheel center nut by fixed head (7) circular hole with micro screw (being axle) head and is connected to a fixed on shell, figure five or two protrudes head (13) and inserts two liang of apertures of figure (16), figure six thick screw rods are screwed in figure four nuts (11) and are connected, and promptly fix treadmill.Two leaf blades use the screw relative fixed on square nylon knife rest, knife rest is fixed in motor shaft head by jackscrew, motor is fixed in i.e. position (5) among the figure two, figure one shell round end place by two flashboards, blade is exposed to figure five square openings (12) and locates, i.e. figure three (9) finger notch places, switch and three pieces of anodal linking to each other of 1.5V batteries series connection.The shell bottom surface is the fixing surface plates of 4 screws, whets a knife, repairs, changes battery so that open, and establishes four plastics suckers below, can be adsorbed in convenient places such as an angle.

In figure six illustrated embodiments, (14) handwheel is split, i.e. screw rod and handwheel.The thin head of screw rod extends through figure two (7) fixed head circular holes and is screwed in the handwheel center nut, promptly is that axle has been fixed and can be changed hands wheel with the micro screw.(13) two protrusion heads extend through guard shield among the figure one (3) and insert (6) protrusion hole among the figure five, the thick screw rod of figure six is screwed in figure four (11) nuts, portable plate promptly is fixed on the shell ladder plane, press (4), the good and sound motor in (5) position, battery, knife rest blade and connect switch, left hand is taken the pencil-knife shell, and it is suitable that thumb mixes up the handwheel blade.Open switch, the right hand is taken one of pencil, and the other end is stretched on the interior blade of pencil guard shield, and the limit is stretched, draws, changeed, and point pressure is given on the limit, rotates blade at a high speed and promptly pencil is whittled into pointed.
