Description

A kind of chi pen

Technical field

The utility model relates to a kind of stationery, especially relates to a kind of chi pen.

Background technology

Lettering pen and ruler are the independent monomers of two kinds of different purposes, usually be all carry respectively, the ruler length that the drawing of different occasion adopts is not identical yet, when carrying out the long straight line of picture as adopted short ruler, junction easily occurs that docking is uneven, causes drawn straight line each other not in the same horizontal line.

Summary of the invention

The purpose of this utility model is for existing deficiency, and provide a kind of ruler and lettering pen to combine the lettering pen be convenient for carrying, its pen cap uses as ruler, and can draw the straight line of indefinite extension.

To achieve the above object, the utility model solves the technical scheme that its technical problem adopts: a kind of chi pen, comprise penholder, the pen cap, the cross section of described penholder is triangle, the seamed edge at these three angles inwardly concaves formation groove, penholder upper end is provided with a ring-type and dashes forward muscle, the cross section of the described pen cap is triangle, the inner chamber of the pen cap inserts with penholder and coordinates, three inwalls on pen cap top are provided with the bump with the prominent muscle phase clamping of penholder, the lower corner angle edge sides of the pen cap is marked with size scale value, the strip projection suitable with penholder groove is provided with corner angle edge under the corresponding surface that size scale value is reverse.

The length of the described pen cap and the same length of penholder.

Three seamed edges of the described pen cap are in line shape.

The beneficial effects of the utility model are: 1. the pen cap uses as ruler, ruler and lettering pen are combined and is convenient for carrying.2. when drawing straight line, can uninterrupted continuous indefinite extension, solve original ruler and cause by the restriction of length and occur that docking is uneven, the phenomenon of straight line curving when continuous picture straight line.

Detailed description of the invention

As Figure 1-5, a kind of chi pen, comprise the penholder 11 of lettering pen, the pen cap 2, the cross section of described penholder 11 is triangle, the seamed edge at these three angles inwardly concaves and forms groove 12, penholder 11 upper end is provided with a ring-type and dashes forward muscle 13, the cross section of the described pen cap 2 is triangle, the inner chamber of the pen cap 2 inserts with penholder 11 and coordinates, three inwalls on the pen cap 2 top are provided with the bump 23 with the prominent muscle 13 phase clamping of penholder, the lower corner angle edge sides of the pen cap 2 is marked with size scale value 21, the strip projection 22 suitable with penholder 11 groove 12 is provided with corner angle edge under the corresponding surface that size scale value is reverse, the length of the pen cap 2 and the same length of penholder 11, three seamed edges of the pen cap 2 are in line shape.

During use, penholder 11 pulls out from the pen cap 2, uses as lettering pen.The pen cap 2 is while indicate using as ruler of size scale value 21, when the straight line needing picture longer, penholder 11 is laterally affixed with the pen cap 2, strip projection 22 sticker on the pen cap is in the groove 12 of penholder, thumb pins penholder 11, and the pen cap 2 againsts penholder 11 and to postpone movement, can continue again the straight line that picture extends, can continue picture by indefinite extension like this, drawn straight line is without the uneven or curving phenomenon of docking.

Claims (3)
