Abstract

The utility model relates to a lead-grinding pencil sharpener, in particular to an electrical lead-grinding pencil sharpener. A short blade is fixed on a shell by a bolt, so that a cutting part is formed; a rotating mechanism comprises a battery, a micro-motor and a switch; an abrasive plate is arranged on the output shaft of the micro-motor; and a guide hole, a gland bush and a cover are arranged on the shell. The cutting part only cuts wood chips; the rotating mechanism drives the abrasive plate to grind the lead into different shapes such as a circular, quadrate or flat shape according to the requirements, the length of the lead can be controlled when wood chips are cut. The lead-grinding pencil sharpener has the following advantages: the structure is simple; the operation is convenient; the lead can be automatically ground; the length of the lead can be controlled during cutting; the lead can be ground into different shapes such as a circular, quadrate or flat shape; wood chips are manually cut; the lead is electrically ground; the use is convenient; and the time and labor can be saved. The lead-grinding pencil sharpener can be widely used to cut various pencils and automatically grind leads.

Description

The plumbous pencil sharpener of electronic mill

Affiliated technical field:

The utility model relates to the plumbous pencil sharpener of a kind of mill, the plumbous pencil sharpener of particularly a kind of electronic mill.

Background technology:

At present, pencil sharpener is that body and blade are formed in the prior art, it is tapered at body to insert pen container, cut wood chip and lead for retractable pencil when cutting lead simultaneously, its shortcoming is the easily broken lead of cutting, and plumbous length is wayward, the scope of application is narrow, because wooden hardness is different with plumbous hardness, the dark lead of wooden penetration of a cutting tool is often because of stressed too big, and the lead that fractures easily.In addition, the fixing plumbous length of blade, pen and lead for retractable pencil concentricity are poor, all are to cause disconnected plumbous reason.

Summary of the invention:

The purpose of the plumbous pencil sharpener of the electronic mill of the utility model is to overcome above-mentioned shortcoming and design the plumbous pencil sharpener of a kind of electronic mill.It is to adopt pilot hole to keep pencil and lead for retractable pencil concentricity height, shortened cutting blade cutting wood chip, and mill is plumbous automatically.

The plumbous pencil sharpener of the electronic mill of the utility model takes following technical scheme to realize, it is to be fixed in by screw by shortened cutting blade to constitute cutting tip on the housing, constitute rotating mechanism by battery and micromachine and switch, the sand sheet is set on the micromachine output shaft, pilot hole and gland and case are set on the housing.Cutting tip only cuts wood chip, and rotating mechanism drives the sand sheet, and it is plumbous to be used for mill, according to demand lead is worn into circle, square, flat etc., can control plumbous length during the cutting wood chip.

The plumbous pencil sharpener effect of the electronic mill of the utility model is simple in structure, easy to operate, automatically mill is plumbous, the plumbous length of control cutting is as required worn into lead shapes such as circle, square, flat, manually cuts wood chip, electronic mill lead, easy to use, time saving and energy saving, be widely used in the cutting of various pencils ground and grind plumbous automatically.

Description of drawings:

The plumbous pencil sharpener of the electronic mill of the utility model will describe in further detail in conjunction with the accompanying drawings.

The specific embodiment:

With reference to Fig. 1,2,3,4, the plumbous pencil sharpener of the electronic mill of the utility model, it is to be connected with housing 9 by shortened cutting blade 3 hold-down screws 1, pilot hole 10 is set on the housing 9 constitutes cutting tip, constitute rotating mechanism by battery 8 and micromachine 5 with switch 2, on micromachine 5 output shafts sand sheet 4 is set, pilot hole 10 and gland 6 and case 7 are set on the housing 9.Cutting tip only cuts wood chip, adopts rotating mechanism to drive sand sheet 4, and mill is plumbous automatically, and lead is worn into circle, square, flat etc., can control plumbous length during the cutting wood chip.

The plumbous pencil sharpener embodiment of the electronic mill of the utility model.It is to be made of cutting tip and rotating mechanism and housing 9, pilot hole 10 and gland 6 and case 7 are set on the housing 9, direct-flow micromachine 5 is supplied with direct current by battery 8, switch 2 control power supplys are provided with sand sheet 4 on micromachine 5 output shafts, and lead is worn into circle, square, flat etc., can control plumbous length during the cutting wood chip, easy to use, time saving and energy saving, be widely used in various pencils ground cutting wood chip and grind plumbous automatically.
