Abstract
The utility model relates to the field of study supplies, in particular to a compasses which comprises a bracket, a suction cup, a slide block and a fixed jacket, and is characterized in that the suction cup is fixed at one side of the bracket which is provided with a slide slot, the slide block is fixed in the slide slot, and the bottom of the slide block is connected with the fixed jacket. The compasses can be provided with scales on the bracket, when the compasses is used, a user can set the size of the radius of an arc to be drawn according to needs; as the compasses is fixed by the suction cup, the defects that the drawing paper is damaged as the compasses is fixed by a fixed pin in the prior art as well as hard drawing paper is difficult to fix are effectively overcome; the length of the radius of the round to be drawn can be set flexibly by moving the slide block in the slide slot; compared with the prior art, the compasses can realize drawing through a single bracket, thus reducing the volume of the compasses remarkably, and the compasses has the advantages of reasonable structure, portability, accuracy and reliability, convenient use, and the like.
Description
Technical field
The utility model relates to the study article field, specifically a kind of compasses.
Background technology
As everyone knows, compasses are one of apparatus commonly used in the study and work, now institute's compasses of selling often are configured to by two propping up of being hinged on the market, one of them support end is provided with locking pin, another support end is provided with fixed cover, use the fixedly center of circle of locking pin during use, and pencil or ball pen be installed in the fixed cover of another support end, holding the compasses upper end is rotated, the circular arc that draws, however because existing compasses adopt the fixedly center of circle of locking pin, in the process of use, need that locking pin is thrust drawing or homework book can be realized fixing, when needs in blackboard or other materials enterprising enforcement time spent, the fixed effect of locking pin is very poor, and in addition, existing compasses are when drawing different circular of radius size, itself and ruler need be used, make troubles to the user.
Summary of the invention
The utility model is at the shortcoming and defect that exists in the prior art, propose a kind of rational in infrastructure, easy to use, volume is little, the compasses of good fixing effect.
The utility model reaches by following measure:
A kind of compasses are provided with support, sucker, slide block, fixed cover, it is characterized in that sucker is fixed on a side of support, and support is provided with chute, and slide block is fixed in the chute, and slider bottom is connected with fixed cover.
The utility model can be provided with scale on support, the user can set drawn arc radius size as required in use.
The utility model is fixed by adopting sucker, effectively overcome in the prior art and to use locking pin fixedly to cause drawing paper damaged and can't realize the shortcoming of fixing hard drawing body, by the slide block in the mobile chute, set the circular radius length of painting flexibly, the utility model compared with prior art, can realize drawing by single support, reduce the volume of compasses significantly, have rational in infrastructure, be easy to carry, accurately and reliably, advantage such as easy to use.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of the utility model medium-height trestle.
Reference numeral: support 1, sucker 2, slide block 3, fixed cover 4, chute 5, scale 6.
The specific embodiment:
A kind of compasses are provided with support 1, sucker 2, slide block 3, fixed cover 4, it is characterized in that sucker 2 is fixed on a side of support 1, and support 1 is provided with chute 5, and slide block 3 is fixed in the chute 5, and slide block 3 bottoms are connected with fixed cover 4.
The utility model can vertically be provided with scale 6 at support 1 upper edge chute 5, and the user can set drawn arc radius size as required in use.
The utility model is by adopting sucker 2 to be fixed, effectively overcome in the prior art and to use locking pin fixedly to cause drawing paper damaged and can't realize the shortcoming of fixing to hard drawing body, by the slide block 3 in the mobile chute 5, set flexibly the circular radius length of painting, the utility model compared with prior art, can realize drawing by single support, reduce significantly the volume of compasses, have rational in infrastructure, be easy to carry, accurately and reliably, the advantage such as easy to use.
