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 pencil lead supplementing device for a propelling pencil. The pencil lead supplementing device comprises a pencil lead box provided with a bullet pencil lead containing cavity. Bullet pencil leads which are arranged transversely in an overlapped mode are arranged in the pencil lead box. The length of the pencil lead box is matched with that of each bullet pencil lead, and the width of the pencil lead box and the height of the pencil lead box are smaller than the length of each bullet pencil lead. The bottom face of the bullet pencil lead containing cavity is provided with a lead outlet, and the two sides of the lead outlet are provided with elastic pieces for controlling the size of the lead outlet. The pencil lead supplementing device for the propelling pencil has the advantages that the structure is reliable, design is reasonable, and the lead changing operation is easy and convenient.

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. ...
