Description

Multi-purpose pen for staff

The utility model belongs to the assistant product of the Writing-painting among the B43L, and it relates to a kind of special structure with pen.

As everyone knows, Western music note spectrum is all used the stave of five lines, and English or phonetic alphabet will be four lines with the every lattice of the exercise book of three lattice when begining to learn exercise.Certainly, these two kinds of dedicated papers all have the printed matter of standard.But emergency requirement or draw squares with ruler for needing for the purpose of the economy is very time-consuming and be difficult for accomplishing symmetrically.Know through investigation, for setting-out spectrum with draw this special pens beyond example still at present of three lattice.

The purpose of this utility model is to provide a kind of special pens that can be used to three lattice exercise-books of picture staff table or English, and it should be operated well, can draw and compare the special-purpose paper of U.S. with standardized product.

By as above design, the staff multipurpose pencil that this programme provided has comprised existing general hard-tipped pen pen core, its concrete feature is: it by the backstay of a body, pen core, spring, location-plate, and the cap for brush forms, its body is the long barrel shape shape,, there are a plurality of through holes that match with the pen core head at the bucket end; Its pen core backstay is a step axle broad in the middle, and the external diameter of an end matches with the endoporus of pen core rear end, and the external diameter of the other end matches with the endoporus of spring; Location-plate is installed in the body, and a plurality of locating holes are arranged on the location-plate, and its position is corresponding with a plurality of holes of body bottom, and it is step-like that the internal diameter in its hole also is, and the internal diameter of big end matches with the external diameter of spring; The cap for brush is the element of the profile sealing identical with a body body opening part, it has the step rim of the mouth on three limits, and on dual-side, all have a flexible ear wing, and this step rim of the mouth cooperates with the internal orifice of a body, and its elastic ear wing matches with two elongated slots of a body both sides.

On a body bottom and the location-plate corresponding hole, five positions is arranged in this programme, these five holes can form a line, and also can line up two row that are staggeredly located.Its body is the long bucket of the square-section of a thin-walled.Its pen core can adopt the hard-tipped pen pen core of universal ball-point pen core, mound pen core, drawing pen core or other standard.
