Abstract
The utility model relates to a pair of compasses with three telescopic feet. The pair of compasses is composed of a rotary shaft, clips, support legs, screws, a toothed nail, compasses points and a pencil lead. The lower end of the rotary shaft is provided with the screws. The clips are divided into a large clip and a small clip. Holes are formed at the upper end and the lower end of each support leg. Teeth are arranged inside at upper ends of the screws on the left and the right. Teeth are arranged at two sides of an upper end of a screw in the middle. The clips are designed at the lower end and internally provided with the compasses points. A compasses point at the right side is divided into upper and lower segments with the interior of an upper segment being hollow and a hole disposed at a lower segment. The upper end of the lower segment is provided with a hole, two sides of which are provided with teeth. A toothed nail with a ring of teeth at the side surface is arranged in the hole. A clip is designed at the lower end and internally provided with a pencil lead or a pencil. The pair of compasses with the three telescopic feet has following beneficial effects: the pair of compasses can also serve as a pair of dividers in addition to a self role so that the pair of compasses and the pair of dividers are prevented from being used in an alternating mode during a drawing process with less trouble and a time-saving characteristic; by detaching relative support legs, the independent pair of compasses and the pair of dividers are formed; and the pair of compasses with the three function is flexible and varied in structures.
Description
Technical field
The utility model relates to a kind of compasses, especially a kind of tripod Telescopic compasses.
Background technology
Compasses are that it is lever, is also wheel shaft for the instrument of picture circle and circular arc.Compasses divide common compasses, bow-spring compasses, drop bow and trammel etc., parts such as rotating shaft, supporting leg, compasses point, pencil-leads, consist of.The method that compasses are drawn circle is the distance first measuring with a yardstick out between compasses bipod, as radius, then the one end with pin is fixed on to a place, as the center of circle, finally the one end with pencil-lead is rotated a circle.
Compasses conventionally and divider be used in conjunction with, divider intercepts line segment, it is very convenient to measure size and decile line segment or circular arc line.It has two supporting legs, and upper end is hinged, and lower end is all stitch, can arbitrarily separate and close up, to adjust the distance between needle point.Divider can be divided into two kinds of common divider and spring dividers, while using divider to measure bisector, should make two needle points accurately drop on lines, must not stagger.While regulating lead for retractable pencil length during existing drawing for compasses, need parbuckle screw, cumbersome, when student attends class manual drawing at ordinary times, need to be used alternatingly divider and measure length, compasses picture circular arc, constantly changes compasses and divider is pretty troublesome, also loses time very much.
Utility model content
In order to overcome the deficiency of above-mentioned existing product, the purpose of this utility model is to provide a kind of tripod Telescopic compasses, its adopts compasses is designed to scalable two types of three supporting legs and three supporting legs, supporting leg is fixed together by large Small clamp and screw, large clip is provided with rotating shaft, has been screwed compasses point on the left side and intermediate support leg, and the right supporting leg divides two sections, between upper-lower section, by finger, fix, on hypomere, be screwed pencil-lead or pencil.
In order to realize the technical scheme that the purpose of this utility model adopts, be: a kind of tripod Telescopic compasses, is characterized in that: it consists of rotating shaft, clip, supporting leg, screw, finger, compasses point, pencil-lead; Described rotating shaft is cylindrical, and side is provided with anti-skidding striped, and lower end is provided with screw thread; Described clip is divided into large clip and Small clamp, and large clip is provided with screwed hole in the middle of upper surface, and inside is provided with Small clamp, and both sides, Small clamp side are provided with three holes, and three holes, on a horizontal line, are provided with screw in hole; The described supporting leg side of being strip, upper and lower side is all provided with hole, in lower stomidium, be provided with screw, have three, inner side, two upper ends, left and right is provided with tooth, and both sides, a middle upper end are all provided with tooth, and the left side and two of centres are equal in length, lower end is designed to clip, in clip, be provided with compasses point, that minute two sections in the right, epimere boring, lower end is provided with hole, hypomere upper end is provided with strip hole, and the both sides in hole are provided with tooth, and in hole, is provided with side with the finger of a circle tooth, lower end is designed to clip, is provided with pencil-lead or pencil in clip.
The beneficial effects of the utility model are: can either work as compasses and use, can work as again divider and use, be used alternatingly compasses and divider while avoiding drawing, bother and lose time; Can become independently compasses and divider by the corresponding supporting leg of dismantling, flexible structure is changeable.
