Problems solved by technology

When the pencil sharpener is working, the pencil sawdust cut by the hob will enter the inner cavity of the runner seat, and the sawdust trapped in the cavity will accumulate, affecting the rotation of the hob and increasing the load on the rocker arm; Further, the wood chips will be stuck in the groove of the internal gear, hindering the rotation of the gear on the internal gear, and affecting the normal operation of the pencil sharpener

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0018] Such as figure 1 , figure 2 with image 3 Shown; a pencil sharpening mechanism and a pencil sharpener including the following technical features, including a rotating wheel seat 1, a knife holder 2 driven by a rocker arm, and a hob 4 mounted on the knife holder 2, on one end of the hob 4 The gear 5 meshes with the internal gear 6 of the runner seat 1. One end of the tool holder 2 is installed in the middle of the inner side of the runner seat 1. The inside of the runner seat 1 is provided with a cavity 7 for gear movement. The chip sweeping block 8 extending in the direction of the internal gear 6 is located in the cavity 7.

[0019] The chip sweep block 8 has an arc structure, and the arc direction of the chip sweep block 8 is consistent with the moving direction of the hob 4 on the runner seat 1. figure 2 The direction pointed by the arrow A is t...

Abstract

The invention discloses a pencil sharpening mechanism, which comprises a rotating wheel seat, a tool rest driven by a rocker arm and a hob arranged on the tool rest, wherein a gear at one end of the hob is meshed with an internal gear of the rotating wheel seat; one end of the tool rest is arranged on the middle part of the inner side of the rotating wheel seat; a cavity for the movement of the gear is formed in the inner side of the rotating wheel seat; a shaving cleaning block extending towards the internal gear is arranged at one end of the tool rest, and is positioned in the cavity. The pencil sharpening mechanism has the advantages that shavings cut from a pencil by the hob fall into the cavity of the rotating wheel seat in a pencil sharpening process, the rocker arm is rotated, then the tool rest rotates along with the rocker arm, and the shaving cleaning block on the tool rest rotates in the cavity of the rotating wheel seat to clean the shavings in the cavity, so that the shavings are prevented from being accumulated in the rotating wheel seat, and influence on the normal work of a pencil sharpener is eliminated.

Description

Technical field [0001] The present invention relates to a pencil sharpener, in particular to a pencil sharpener mechanism and a pencil sharpener equipped with the pencil sharpener mechanism. Background technique [0002] Pencil sharpeners can sharpen pencils safely and quickly. Pencil sharpeners have become an essential tool for students to learn. The pencil sharpener includes a box body, a pen clamping mechanism and a pencil sharpening mechanism. The pencil sharpening mechanism includes a rocker arm, a runner base, a knife rest and a hob. The knife rest is installed on the box body through the runner base, and the hob is installed through a pin. On the tool holder, the hob meshes with the internal gear on the runner seat through a gear. The rocker arm drives the tool holder and the hob to rotate together. At the same time, the hob rotates through gear meshing. Since the gear connected to the hob rotates along the internal gear on the runner seat, there is a space for the g...
