Abstract
The utility model relates to an electric sharpener for pencil, which comprises an outer covering, a micro motor, a knife frame, a parallel screw milling cutter, a cutter spindle, an internal gear, an external gear and a transmission mechanism. According to the theory of rotation and revolution, various pencils including glass pencils can be sharpened by the parallel screw milling cutter driven by the micro motor; the electric sharpener for pencil is provided with safety device and illumination alarm unit with double switches. The utility model has the advantages that the pencil can be sharpened rapidly with tiny torque; the pencil lead can not be broken off; simultaneously, the appearance of the sharpened pencil is regular and attractive; the electric sharpener for pencil is particularly suitable for the primary and secondary school students, and can be one part of the automatic office equipment.
Description
The utility model relates to a kind of stationery of the usefulness that sharpens a pencil, particularly a kind of electronic pencil sharpener.
The pencil sharpener of Chu Shouing, pencil sharpener in the market, great majority adopt cuts pen by hand, both uses and requires great effort, be easy to disconnected core again, the pencil of cutting out is not attractive in appearance yet, existing electronic pencil sharpener, it manually is electronic also just changing simply, and above shortcoming still is difficult to overcome.
The purpose of this utility model provides a kind of novel electronic pencil sharpener, uses this pencil sharpener, the continuous core of pencil, and the pencil good looking appearance of cutting out is neat.
Task of the present utility model is finished in the following manner: with reference to accompanying drawing 1-4, this electronic pencil sharpener is by shell (1), micro machine gear (2), micro machine (3), travelling gear (4), travelling gear (5), driven wheel (6), knife rest (7), contain bits lids (8), cutter spindle (9), garden post screw-on cutter (10), external gear (11) is formed with internal gear (12), garden post screw-on cutter (10) is fixedlyed connected with external gear (11), with cutter spindle (9) for movingly, external gear (11) and internal gear (12) engagement, internal gear (12) is fixed on the shell (1), cutter spindle (9) is fixed on the knife rest (7), knife rest (7) is fixedlyed connected with driven wheel (6), driven wheel (6) is by travelling gear (4), (5) with micro machine gear (2) engagement, micro machine gear (2) is fixedlyed connected with micro-motor.Garden post screw-on cutter (10) is seven teeth, and the general milling cutter in forward and backward angle is big, so both has been convenient to chip removal, is unlikely to make cutter and pen to block again.
This electronic pencil sharpener is provided with the safety guard of dual-switch, with reference to Fig. 5, and K among this figure
1With K
2Be two switches on the electronic pencil sharpener, close K when containing bits lids (8)
1Close, pencil inserts pencil sharpener, promotes K
2Connect motor circuit, micro machine (3) energising is rotated, and drives garden post screw-on cutter (10) and rotates.Open K if contain bits lids (8)
1Promptly open, even pencil inserts K
2Close, circuit is also obstructed, and micro machine (3) can not rotate, so milling cutter can not rotate yet, and the milling cutter that can avoid user's hand to be rotated is like this run over and injure.
When the utility model uses, be to make power supply with dry cell, after circuit was connected, micro machine (3) rotated, and by micro machine gear (2), travelling gear (4), (5), made driven wheel (6) drive knife rest (7) and cutter spindle (9) around pencil axis (L
2) revolution, by the engagement of external gear (11),, thereby make external gear (11) and garden post screw-on cutter (10) again around its axis (L owing to internal gear (12) maintains static with internal gear (12)
1) rotation, along with garden post screw-on cutter (10) rotation constantly and revolution, pencil moves from top to bottom, and pencil just constantly is cut, till forming a neat positive cone.
Also adorned an illuminance warning device on the utility model, promptly when the light deepening, this device can give the alarm automatically, and reminds people is in time turned on light.
Advantage of the present utility model: adopt this pencil sharpener, use very little moment of torsion, just can cut pencil rapidly, the pencil good looking appearance of cutting out is neat, and constantly core is safe in utilization.This pencil sharpener can be applicable to comprise the various pencils of chinagraph pencil, is particularly suitable for students in middle and primary schools and uses, and also be the part of office equipment automation.
