Abstract

The utility model discloses an electric pencil sharpener, which is composed of a short blade sharpener, a small motor, a small gear, a big gear, a grinding wheel, a fixed grinding sheet, a power switch, a case, and an external cover, wherein, the short blade sharpener just cuts the outer wood of a pencil in a rotating way, leaving a lead core behind, and then the exposed lead core is grinded by the grinding wheel which is driven by the small motor, or the lead core is grinded by hand on the fixed grinding sheet, and the length, the taper, the thickness, the thinness and the shape of the lead core can be left and grinded arbitrarily according to a requirement. The utility model has the advantages of convenient use, fast writing, no fracture of the lead core, and no waste of pencils. The utility model is an ideal tool for writing and drawing.

Description

Electric pencil sharpener

The utility model relates to a kind of instrument that is applicable to the skiving pencil.

The pencil sharpener of existing known a kind of roll cutting pencil, the pencil tapering that volume is cut out is big, the lead for retractable pencil that exposes not only point but also weak point, easily disconnected lead for retractable pencil is write thick rust easily when writing, and is not easy to write, more be not suitable for mechanical drawing, the mechanical drawing personnel must reserve long lead for retractable pencil to pencil for the ease of drawing, and pocket knife therefore commonly used is manual to sharpen a pencil, but it is very slow with the manual speed that sharpens a pencil of pocket knife, also bad operation uses pencil sharpener also to roll up disconnected lead for retractable pencil, waste pencil easily.

The purpose of this utility model is that a kind of electric pencil skiving device will be provided, and can become length, tapering, thickness and the shape that needs arbitrarily to the lead for retractable pencil skiving of pencil, and constantly lead for retractable pencil is easy to operate, quick.

The utility model is achieved in that the housing of an internal battery, a shortened cutting blade pencil sharpener is arranged on housing, a small size motor is equipped with on the next door of shortened cutting blade pencil sharpener, small size motor drives a Grinding wheel by gear drive, a fixing abrasive sheet also is equipped with in the side of shortened cutting blade pencil sharpener, and power switch is installed on the housing, and an enclosing cover covers on the upper end of housing, the shortened cutting blade pencil sharpener and fixedly abrasive sheet also can combine separately, constitute a kind of manual pencil skiving device.

Below in conjunction with accompanying drawing an embodiment of the present utility model is elaborated.

Accompanying drawing is a three-dimensional cutaway view of the present utility model.

The housing of an internal battery (10), one pencil sharpener body (9) is arranged on housing (10), shortened cutting blade (12) is fastened on pencil sharpener body (9) with screw (7) and goes up shortened cutting blade pencil sharpener of composition, the length of shortened cutting blade (12) is by the length of the outer timber element of cone of roll cutting pencil, do not touch lead for retractable pencil, on the next door of pencil sharpener body (9) small size motor (6) is housed, on the axle of small size motor (6) pinion (4) is housed, pinion (4) and gear wheel (3) engagement, gear wheel (3) is contained on the power transmission shaft (5), a Grinding wheel (2) is equipped with in the upper end of power transmission shaft (5), one fixing abrasive sheet (11) also is housed in the side of pencil sharpener body (9), Grinding wheel (2) and fixedly abrasive sheet (11) method that is used in the many little protruding holes of stalloy upper punch make, also can be bonded with the emery wheel abrasive material of carborundum class, power switch (8) is installed on the housing (10), and enclosing cover (1) covers on the upper end of housing (10).During use, take off enclosing cover (1), on the shortened cutting blade pencil sharpener, the outer field timber volume of pencil is reamed earlier, stay lead for retractable pencil, the length of lead for retractable pencil just can be determined arbitrarily according to the timber length that is reamed by volume like this, because shortened cutting blade (12) do not contact lead for retractable pencil, thus continuous lead for retractable pencil during roll cutting pencil, after volume has been cut the outer field timber of pencil, promote power switch (8), start small size motor (6), drive Grinding wheel (2) quick rotation, then, pencil is taken Grinding wheel (2) go up the reconditioning lead for retractable pencil, like this, the tapering of lead for retractable pencil, thickness and shape also just can unrestricted any reconditionings, equally also can go up the hand grinding lead for retractable pencil at fixing abrasive sheet (11).The shortened cutting blade pencil sharpener of forming by pencil sharpener body (9), shortened cutting blade (12) and screw (7) and fixedly abrasive sheet (11) combine separately, then can constitute a kind of manual pencil skiving device.

The utility model can become length, tapering, thickness and the shape that needs arbitrarily to the lead for retractable pencil skiving of pencil, and constantly lead for retractable pencil is easy to use, quick, does not waste pencil.
