Mechanism capable of adjusting thickness of pencil lead tip for pencil sharpener and pencil sharpener

Abstract

The invention discloses a mechanism capable of adjusting thickness of a pencil lead tip for a pencil sharpener. The mechanism capable of adjusting the thickness of the pencil lead tip for the pencil sharpener comprises a sliding stopper which is independently arranged on a knife rest, a rotary button installed on a rocking arm and a telescopic pole, wherein one end of the telescopic pole is arranged in the knife rest in a penetrating mode and can move in the knife rest in the axial direction; the other end of the telescopic pole is connected with the rotary button through a thread, a spring is arranged on the telescopic pole in a sleeving mode, and the spring abuts against the portion between the inner side of the rotary button and the end of the knife rest; the rotary button is rotated, and the telescopic pole slowly moves forward to push the sliding stopper into a pencil hole; the rotary button is pressed inwards, and the telescopic pole rapidly moves forward to push the sliding stopper into the pencil hole. The mechanism capable of adjusting the thickness of the pencil lead tip for the pencil sharpener has the advantages that when a pencil is sharpened, broken pencil lead and wood are often blocked in the front side of the pencil hole, normal operation of the pencil sharpener is affected, the rotary button is pressed inward, and the telescopic pole rapidly moves forward to push the sliding stopper into the pencil hole, so that the broken pencil lead and the wood are pushed out, and the trouble that in the past, the broken pencil lead and the wood need to be cleaned away by opening the pencil sharpener is solved.

Description

technical field [0001] The invention relates to an adjustable pencil sharpener, in particular to a pencil sharpener with an adjustable mechanism for the tip of a pencil core on the pencil sharpener. Background technique [0002] Because the pencil sharpener can sharpen pencils safely and quickly, the pencil sharpener has become an essential tool for students to learn to write. The existing pencil sharpener can cut out pencil nibs of different thicknesses, satisfying students' various uses as writing tools. The Chinese invention patent with the Chinese patent number 200920181206.3 discloses an adjustable pencil sharpener hob combination, which specifically discloses that one end of the hob meshes with the internal gear on the runner seat through a gear, and the center axis of the knife seat corresponds to the pen feeding The hole is provided with a through hole, and the center of the through hole is provided with an adjustment shaft, and an adjustment arm pivotally arranged ...

AI Technical Summary

Problems solved by technology

There are the following problems in the above-mentioned adjustable mechanism of pencil core tip thickness: 1. The mechanism is relatively complicated on the whole, and the processing is relatively precise, which increases the production cost

2. When sharpening a pencil, there are often broken cores and sawdust blocking the front side of the pen inlet hole, which affects the normal operation of the pencil sharpener

3. The tip of the pen core can only be cut into multiple gears, not stepless cutting
