Description

Integrated mechanism with adjustable pencil sharpening lamp control and 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 with adjustable pencil sharpening lamp control and pencil point of pencil sharpener and an assembling method thereof.

Background

The pencil sharpener is used as a pencil sharpening tool and is popular with students, and the pencil sharpener generally comprises a main body, a pencil feeding mechanism, a knife rest and a rocker arm.

Most hand pencil sharpener in the prior market use automatic pencil feeding and withdrawing mechanism. Because this kind of structure is simpler convenient than the pull-out centre gripping formula pen feeding mechanism of old money before, can not press from both sides the finger, and the student prefers. However, the existing pencil sharpener has the following defects:

(1) The automatic pencil feeding mechanism has a great disadvantage that a user does not know that pencil sharpening is performed all the time after pencil sharpening, so that pencil leads are broken, and the user does not know that pencil sharpening is performed all the time after pencil sharpening, so that a lot of pencils are wasted (especially art pencils, because art students use long-lead pencils and carbon pencils, the carbon pencils are fragile and easy to break, and if pencil sharpening is not stopped immediately after the long-lead is sharpened, the pencil is broken, and a great amount of resources and time are wasted);

(2) The pencil carbon sharpening broken pencil leads are the difficulties which need to be solved urgently by all pencil sharpening machines in the market at present;

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

(4) The pencil sharpener cannot freely adjust the thickness of the pencil lead, the thickness of the pencil point after sharpening is the same, and the user selectivity is poor. Although pencil sharpener capable of adjusting the thickness of the pencil point is also disclosed, for example, a direct-pushing two-gear pencil point thickness adjusting mechanism of the pencil sharpener and the pencil sharpener of China patent No. 201711286308.7 are characterized in that the structure between a button, a guide sleeve and a guide rod is skillfully matched, the button is pressed by a hand of a user, and the button is pressed to achieve two axial positions of the guide rod, namely, the position of the pencil point in a first state is the thinner position of the pencil point; the position in the second state is the position when the pencil point is thicker, and the push rod stretches into the position of the knife rest to limit the thickness of the pencil point after the pencil point is cut, and the guide rod is fixed with the push rod which can limit the thickness of the pencil point. The pencil sharpener meets the requirements of thicker pencil points and thinner pencil points by directly pushing the button, but has only two gears and cannot be adjusted in multiple stages according to the requirement.

In order to overcome the defects, the invention discloses an integrated mechanism with an adjustable pencil sharpening lamp control and a nib of a pencil sharpener and an assembling method thereof.

The left side of regulator is equipped with three left limit location arc piece that is used for adjustable nib thickness, is equipped with three circular spacing posts in the transparent back lid for the limit of right limit of adjustable nib thickness.

(3) With the function of replacing worn hobs

The replaceable hob assembly can be realized without disassembling other parts, only the machine rice screw is required to be disassembled by using the tool, the blunt hob can be disassembled to replace a new hob, the operation is simple and convenient, and the cost of purchasing a new pencil sharpener is saved.

Compared with the existing pencil sharpener structure, the pencil sharpener structure has the advantages that the LED lamp is on, whether the pencil is sharpened to an adjustable (set) degree is identified, the LED lamp is suddenly extinguished to indicate that the pencil lead is broken, whether the pencil is sharpened (namely, the lamp is on) or not is known to be finished by observing the transparent rear cover, the pencil is not always sharpened, the condition that sharpening is not yet known is not caused, and pencil lead breakage and pencil waste are not always caused by sharpening, so that resources and time are saved. The nib thickness is adjusted, through the cooperation of internal and external screw thread, stepless regulation, nib's selection scope is wide. In a word, this scheme simple structure is reasonable, and the function is many, convenient operation, can not break the core, the quality has the guarantee.
