Description

A kind of drawing compass
Technical field
The utility model is related to student and engineers and technicians' design drawing tool, specifically a kind of drawing compass.
Background technology
Drawing compass is commonly called as compasses, is the indispensable tool of engineers and technicians' drawing of students in middle and primary schools and all trades and professions, makes It is wider with range.But traditional compasses have a disadvantage that:
1. drawing point when carrying easily to hurt sb.'s feelings, it is inconvenient to carry that proprietary box need to be customized;
2. the pencil-lead used is easily broken;
3. duck-beak type dips in water inconvenience.
By retrieval, application number:200920015540.1 publication date 2010-05-12 discloses a kind of Novel compasses, packet Link and the pen cap are included, link is made of internal and external casing, and one end axis connection of internal and external casing, and is set on internal and external casing slotting Hole, peripheral hardware bolt are fixed;Handwriting is connected in the affixed pen cap of the other end of internal and external casing, and in pen cap interpolation type.Storage and When carrying, pen can be removed, link is reduced to most short, the volume of compasses can be reduced, to store;Draw circle when It waits, the length of casing can be adjusted according to diameter of a circle, penholder is placed in the pen cap, picture can be convenient for justify.
Although the compasses of technology disclosed above disclose the features such as the pen cap, but overall technical architecture, technology to be solved Problem, technique effect etc., all differ with the utility model.For example link blocks adjusting of the pen in the pen cap, causes one A compass leg is long, and a compass leg is excessively short, is unfavorable for picture circle.
Invention content
The purpose of this utility model is to provide a kind of drawing compass, the pen cap is cartridge type, and can be loaded pencil, water-color paintbrush etc. are various Pen, it is convenient and practical.Compasses volume after folding is minimum, modern design, is furnished with key chain, carries more convenient.In the axis side of the pen cap Upwards without any blocking, convenient for adjusting the length of pen, to coordinate the length of compass leg.
In order to achieve the above objectives, the utility model uses following technical solution, a kind of drawing compass, including mutually cuts with scissors The compass leg and the pen cap connect, on the pen cap setting be used for holding out against marking closely for pen, the pen cap is the tubular body of formula up and down, Without view obstruction on the axis direction of the pen cap, an otic placode is arranged in the pen cap outer wall, and the compass leg includes principal arm, draws Point, the principal arm upper end and otic placode are hinged, and principal arm lower end and stroke point are hinged, and described stroke of sharp length is less than or equal to the length of principal arm Degree.
In order to achieve the above objectives, the utility model uses following technical solution, a kind of drawing compass, including mutually cuts with scissors The compass leg and the pen cap connect, on the pen cap setting be used for holding out against marking closely for pen, which is characterized in that the pen cap is up and down An otic placode, the compass leg packet is arranged without view obstruction, the pen cap outer wall on the axis direction of the pen cap in the tubular body of formula It includes and draws Retractive leg sharp and that at least three-level is nested successively, described stroke of point is telescopic in the Retractive leg of most next stage, most The Retractive leg upper end of upper level and otic placode are hinged, setting group handle on described stroke of point.
The cannelure for accommodating and dialling handle is opened up on the Retractive leg.
The hinged place of the Retractive leg and otic placode, which is worn, is connected to chain belt.
Compared to the prior art, the utility model has the advantages that:
1, compasses are designed as single-leg type, and cost of manufacture is lower;
2, the pen cap is cartridge type, and can be loaded the various pens such as pencil, water-color paintbrush, convenient and practical;
3, compasses volume after folding is minimum, modern design, is furnished with key chain, carries more convenient;
4, without any blocking on the axis direction of the pen cap, convenient for adjusting the length of pen, to coordinate the length of compass leg;
5, compasses design is safe and reliable, is particularly suitable for students in middle and primary schools and uses.
