Abstract
The utility model relates to a kind of compasses, particularly a kind of multi-core type compasses.These multi-core type compasses, comprise handle, handle is connected with the first support arm and the second support arm, it is characterized in that: described the first support arm end is connected with syringe needle, the second support arm end is arranged with cylinder, cylinder both sides are connected with respectively support bar, and support bar afterbody is connected with pen core by the second clamping screw respectively.The beneficial effects of the utility model are: removed the worry of changing pen core from, can draw various annulus; Simple in structure, easy to use, be convenient to regulate, facilitated vast arduous designer, for they have alleviated mapping burden.
Description
(1) technical field
The utility model relates to a kind of compasses, particularly a kind of multi-core type compasses.
(2) background technology
At present, although many mappings are all to complete on computers, in some important engineering designs, still need paper drawing and manual drawing, simultaneously for the manual indispensable subject especially of drawing of beginner.We are when each mapping, compasses pencil-lead is with changing pen core after a period of time, this brings very burden to mapping, not only waste the mapping time but also change lead for retractable pencil and easily pollute drawing, also can have influence on student's mapping state, cause irritated grade for unhealthy emotion, thereby while causing drawing, error rate significantly rises and reduces mapping efficiency, if as will be greatly affected total marks of the examination in examination.Although there are in the market a kind of automatic propelling formula compasses, although facilitated, change core, can only replace the lead for retractable pencil of same type, cannot replace various model lead for retractable pencils.
(3) summary of the invention
The utility model is in order to make up the deficiencies in the prior art, and a kind of simple in structure, easy to use, multi-core type compasses of improving mapping efficiency are provided.
The utility model is achieved by the following technical solution:
A kind of multi-core type compasses, comprise handle, handle is connected with the first support arm and the second support arm, it is characterized in that: described the first support arm end is connected with syringe needle, the second support arm end is arranged with cylinder, cylinder both sides are connected with respectively support bar, and support bar afterbody is connected with pen core by the second clamping screw respectively.
Described cylinder is connected by the first screw thread with the second support arm outside, and cylinder center is equipped with the 3rd clamping screw, and the 3rd clamping screw is threaded by second with the second support arm inside.
Described syringe needle is connected with the first support arm by the first clamping screw, and the first support arm bottom offers groove.
Described the first support arm is connected with handle with the second gear by the first gear respectively with the second support arm, and the first gear is meshed with the second gear.
The beneficial effects of the utility model are: removed the worry of changing pen core from, can draw various annulus; Simple in structure, easy to use, be convenient to regulate, facilitated vast arduous designer, for they have alleviated mapping burden.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 handle, 2 first support arms, 3 second support arms, 4 syringe needles, 5 cylinders, 6 support bars, 7 second clamping screws, 8 pen cores, 9 first screw threads, 10 the 3rd clamping screws, 11 second screw threads, 12 first clamping screws, 13 grooves, 14 first gears, 15 second gears.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises handle 1, handle 1 is connected with the first support arm 2 and the second support arm 3, the first support arm 2 ends and is connected with syringe needle 4, the second support arm 3 ends and is arranged with cylinder 5, cylinder 5 both sides are connected with respectively support bar 6, and support bar 6 afterbodys are connected with pen core 8 by the second clamping screw 7 respectively.Cylinder 5 is connected by the first screw thread 9 with the second support arm 3 outsides, and cylinder 5 centers are equipped with the 3rd clamping screw 10, the three clamping screws 10 and are connected by the second screw thread 11 with the second support arm 3 inside.Syringe needle 4 is connected with the first support arm 2 by the first clamping screw 12, and the first support arm 2 bottoms offer groove 13.The first support arm 2 is connected with handle 1 with the second gear 15 by the first gear 14 respectively with the second support arm 3, and the first gear 14 is meshed with the second gear 15.
Adopt a kind of multi-core type compasses of the present utility model, in use can remove the worry of changing pen core from, two pen cores 8 can be used for picture annulus simultaneously.Unclamp the second clamping screw 7, rotation pen core 8, then tightens the second clamping screw 7 and can change the angle between pen core 8 and support bar 6.When pen core 8 is used up a part of when too short, can turn cylinder 5 downwards so that pen core 8 keeps concordant with syringe needle 4 by the first screw thread 9, with the 3rd clamping screw 10, by the second screw thread 11, be connected with the second support arm 3 inside, can further reinforce the tautness of cylinder 5 and the second support arm 3.Cylinder 5 is held handle 1, rotation the first support arm 2 or the second support arm 3, and under the effect of the first gear 14 or the second gear 15, the second support arm 3 or the first support arm 2 just can rotate by automatic winding handle 1, easy to operate.After being finished, can unscrew the first clamping screw 12, syringe needle 4 is screwed in groove 13, can prevent syringe needle 4 passivation and stab people and avoid dangerous.
