Propelling pencil with pencil lead uniform and fine writing function

Abstract

The invention discloses a propelling pencil with a pencil lead uniform and fine writing function, and relates to the technical field of propelling pencils. The propelling pencil comprises a pencil point, a pencil head, a pencil body, a pencil lead cylinder, a lead outlet mechanism and a rotating mechanism. The pencil point is arranged at the bottom end of the pencil head, the pencil head is arranged at the bottom end of the pencil body, the pencil lead cylinder is arranged in the pencil body, the lead outlet mechanism is arranged in the pencil body and located at the bottom of the pencil lead cylinder, and the rotating mechanism is arranged between the pencil body and the pencil lead cylinder. Angle rotation of the pencil lead is carried out through writing pressure changes, a user only needs to write like a common propelling pencil, angle rotation of the pencil lead can be automatically achieved, and the problem that a pencil holder needs to be rotated after a traditional propelling pencil is used for a period of time is solved. The device in the pen body has a buffering function, and certain buffering protection can be provided for the pen point when the pen point falls accidentally.

Description

technical field [0001] The invention relates to the technical field of mechanical pencils, in particular to a mechanical pencil with the function of making the lead core even and fine for writing. Background technique [0002] When using a mechanical pencil to write, the front end of the lead of the mechanical pencil will wear out as the writing continues to form an inclined surface, which will cause the written handwriting to gradually become thicker and lighter, affecting the appearance of the font and the recognition of the text. In order to make the handwriting even and thin, people usually need to constantly rotate the pen holder, which is really troublesome. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a mechanical pencil with the function of making the lead lead even and thin for writing. The mechanical pencil rotates the lead lead through the pressure difference between writing and lifting the pen...
