Problems solved by technology

However, when the lead in the core tube of the refill pencil is used up and the bullet lead needs to be replenished, it needs to be replaced manually, and inserted one by one from the pencil lead inlet, the operation is cumbersome and time-consuming, and the fingers touch the lead. Unhygienic; especially for younger students, it is more laborious to change the core by yourself

Abstract

The invention discloses a lead refilling device for a mechanical pencil, which comprises a lead box with the bullet lead core accommodating cavity, the bullet lead cores arranged and stacked horizontally are arranged in the lead box, and the lead box The length matches the length of the lead core of the bullet head, the width of the lead core box and the height of the lead core box are both smaller than the length of the lead core of the bullet head. size flex. The invention has the advantages of reliable structure, reasonable design and simple and convenient core changing operation.

Description

technical field [0001] The invention relates to a stationery product, in particular to a sharpening-free pencil whose core is extruded by pressing. The pencil lead of the pencil is replaceable and free of sharpening. Through the pressing operation, the lead core is sent out from the core storage device to realize the core changing operation. Background technique [0002] Pencils are commonly used stationery by the majority of students. Ordinary pencils need to be continuously cut during use, and the nib needs to be repaired frequently. Sharpening the pencil is time-consuming and laborious, and it is inconvenient to use; therefore, it is gradually replaced by the no-sharpen pencil. [0003] At present, there is a kind of non-sharp pencils on the market. The lead core is divided into several pencil sections with pointed ends, which are socketed up and down to form a non-sharp pencil. Since the pencil is fixed by clamping up and down, it is easy to break due to weak connection. ...
