Abstract

The invention discloses a peeling-free pencil lead protection sleeve, and relates to the technical field of stationery commodities. The peeling-free pencil lead protection sleeve comprises a pencil holder. The pencil holder is in a pipe shape, the upper end of the pencil holder is opened, and the lower end of the pencil holder is provided with a pencil mouth for a pencil lead to stretch out. A stretching-out hole of the pencil mouth is provided with a pencil lead guiding sleeve. A pencil lead telescopic protection sleeve is arranged at the upper end of the pencil mouth, and a pressing block is arranged at the upper end of the pencil lead telescopic protection sleeve. The peeling-free pencil lead protection sleeve can solve the problems that a current peeling-free pencil lead is prone to fracture, and the stretching-out length of the pencil lead cannot be controlled.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a protective case using a pencil lead. Background technique [0002] At present, the non-sharpening pencil generally puts a long pencil lead or a short pencil lead in a plastic tube, and the plastic tube is placed in the pen tube. There is a push button on the upper part of the pen tube. Every time the pencil user presses it, the push button pushes down The pressure rod moves downwards, so that the pencil lead in the plastic tube exposes a part of the pencil mouth. Since the downward distance of the pressure rod is the same every time the button is pressed, this kind of sharpening-free pencil cannot control the movement of the pencil lead from the mouth every time. In addition, because the pencil lead is placed in the plastic tube, its protruding end is exposed through the nib, and the pencil user uses too much force, and the pencil lead is easily broken, resulting in waste of...
