Description
[technical field]
The utility model relates to the technical field of compasses, particularly a kind of technical field of sliding compasses.
[background technology]
Compasses are used to the instrument drawing circle or string in mathematics and drawing, and be usually used in construction with ruler and compasses, the invention of compasses can trace back to the Chinese Xia dynasty the earliest, and in the inscriptions on bones or tortoise shells of B.C. the 15th century, existing rule, square two word, be called " rule ", i.e. the compasses of today at that time.Paint round drawing instrument.Have two pin, upper end thereof, lower end can arbitrarily separate or close up, to adjust the size of painted arc radius.The end of a pin is needle point, and the end of another pin can load the pin painting pencil line or the line of ink marker.Extension rod loaded onto by some compasses, can draw larger circle.There are trammel, springer bow and heart bow compasses etc. of living.
Traditional compasses length direction cannot fold, for the compasses that some are larger, store inconvenient, in application process, radius of a circle cannot directly be determined, needs to have assisted with ruler, operate more complicated, a kind of compasses of market demand, can fold, reduce the space taken, can set simultaneously and need diameter of a circle, application is simple.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of sliding compasses, can make compasses folded lengthwise, reduces the space taken, and carries and store conveniently, and can set needs diameter of a circle simultaneously, and application is simple, easy to adjust.
For achieving the above object, the utility model proposes a kind of sliding compasses, comprise center of circle holder, mobile jib, clamping plate, nib set bolt, nib, folding bolt and folding rod, holder top, the described center of circle is provided with handle, holder bottom, the center of circle is provided with locking pin, center of circle holder and mobile jib are articulated and connected, described mobile jib is provided with mobile jib slideway, mobile jib is connected with folding rod by folding bolt, described folding rod is provided with folding rod slideway, the described upper and lower both sides of folding rod slideway are respectively arranged with clamping plate, the clamping plate on top are provided with written set bolt, the clamping plate of bottom are provided with nib.
As preferably, described handle is cylindric, and the cambered surface of handle is provided with projection.
As preferably, described written upper end is provided with internal thread, and described written set bolt is provided with external screw thread, and described internal thread is fixedly connected with external screw thread.
The beneficial effects of the utility model: the utility model is by being applied in compasses by center of circle holder, mobile jib, clamping plate, written set bolt, nib, folding bolt and folding rod, compasses folded lengthwise can be made, reduce the space taken, carry and store conveniently, can set simultaneously and need diameter of a circle, application is simple, easy to adjust.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
