Description

Integrated mechanism for controlling pencil sharpening lamp and adjusting pencil point of pencil sharpener and assembling method thereof

Technical Field

The invention relates to the technical field of pencil sharpener, in particular to an integrated mechanism for pencil sharpener lamp control and adjustable pencil point of a pencil sharpener and an assembling method thereof.

Background

The pencil sharpener is a pencil sharpening tool and is popular with students, generally comprises a main body, a pencil feeding mechanism, a knife rest and a rocker arm, when in use, a pencil is placed into a pencil feeding hole, and the rocker arm is shaken by hands to sharpen the pencil.

Most of the existing hand-operated pencil sharpeners on the market use an automatic pencil feeding and withdrawing mechanism. Compared with the prior old drawing clamping type pen feeding mechanism, the structure is simpler and more convenient, and can not clamp fingers, so that students prefer the structure. However, the existing pencil sharpener has the following defects:

(1) the automatic pencil feeding mechanism has the great defects that a user cannot know that pencil sharpening is carried out all the time after sharpening the pencil, so that a lead core is broken, and cannot know that pencil sharpening is carried out all the time after the pencil sharpening is broken, so that a lot of pencils are wasted (particularly, art pencils are fragile and easy to break because art workers use long-lead pencils and carbon pencils, and therefore, the pencil sharpening is broken if the pencil sharpening is not stopped immediately after sharpening the long lead core, and a large amount of resources and time are wasted);

(2) the charcoal pencil leads are cut off, which is a difficult point to be solved by all pencil sharpeners in the market at present;

(3) the pencil sharpener cannot test the sharp limit of each brand of pencil charcoal, and a user cannot know that the pencil sharpening can be continued after the lead of the pencil is broken, so that great loss is caused.

(4) The pencil sharpener can not freely adjust the thickness and the length of the pencil lead, the thicknesses of the pencil points after pencil sharpening are the same, and the user selectivity is poor. Although a pencil sharpener capable of adjusting the thickness of a pencil point also appears, for example, in chinese patent No. 201711286308.7, "straight-push two-stage type pencil point thickness adjusting mechanism and pencil sharpener" of pencil sharpener, the button is pressed by the hand of a user through the ingenious matching of the structure among the button, the guide sleeve and the guide rod, and two axial positions of the guide rod are reached by pressing the button, namely, the position in the first state is the position when the pencil point is thinner; the position under the second state is the position when the pencil nib is thick, the position that the push rod stretches into the tool rest limits the thickness of the pencil nib after cutting, and the guide rod is fixed with the push rod capable of limiting the thickness of the pencil nib. The pencil sharpener meets the requirements of a thick pen point and a thin pen point of a pencil in a mode of pushing the button directly, but has only two gears and cannot be adjusted in multiple stages as required.

In order to overcome the defects, the invention provides an integrated mechanism for controlling a pencil sharpening lamp and adjusting a pencil point of a pencil sharpener and an assembling method thereof.
