Abstract
The utility model relates to a novel compass, including a supporting rod, a rotation rod and a cross rod; wherein, the supporting rod is parallel to the rotation rod, both ends of the cross rod are connected with the supporting rod and the rotation rod; the cross rod has an extension structure, both ends of the cross rod are sleeved with each other; the top of the supporting rod is provided with a sucker while the bottom of the supporting rod is provided with a pointer; the top of the rotation rod is tubular; chalks are inserted into the tube; the screw thread at the mouth of the tube is screwed with a rotation sleeve; the bottom of the rotation rod is connected to a pencil; the pointer is provided with a protective sleeve. When the compass is used for drawing pictures on paper, the pointer is set in the paper, the pencil arranged in the rotation rod touches the paper, the length of the cross rod is adjusted until being equal to the radius of a semicircle to be drawn, finally the rotation rod is turned and the pencil is used for drawing pictures. When the compass is used for drawing pictures on a blackboard, the blackboard is adsorbed with the sucker, a chalk arranged in the rotation rod touches the blackboard, and other operations are as above. The novel compass has reasonable structure, extensive application, unique design, simple technics, flexible operation, etc.
Description
Technical field
The utility model relates to a kind of drawing instrument, especially a kind of new-type compasses.
Background technology
As everyone knows, compasses are one of most important instruments in drawing, learn, working.But present compasses function ratio is more single, can only draw on a kind of plane, can't satisfy people's demand.In addition, present compasses are dangerous in use, accidentally just can stab by supported bar pointer, cause serious consequence.For this reason, it is extremely important that we provide a kind of new-type compasses.
Summary of the invention
The purpose of this utility model provides a kind of new-type compasses, is used to solve the problem of common compasses function singleness.
For achieving the above object, the new-type compasses of the utility model comprise support bar, swingle and cross bar, support bar and swingle keeping parallelism, and the cross bar two ends are connected with both stage casings are vertical; The bar shaped of the cross bar side of being is divided into two sections, and two sections mutually nested, forms stretching structure; Supporting bar top is provided with sucker, and pointer is installed in the bottom; The swingle top is a tubulose, offers two openings from the mouth of pipe along swingle axis direction symmetry, and chalk inserts in the mouth of pipe; At mouth of pipe place screw thread socket rotary sleeve; The swingle bottom connects pencil; Protective sleeve is installed at the pointer place, and protective sleeve is threaded with support bar; Two sections nested type cross bar surfaces are provided with the length scale.
After adopting said structure, when drawing, the pointer of support bar bottom is assigned fixing on paper on paper, what this moment, swingle contacted with paper is pencil, regulates cross bar length, makes it equal to wait to paint the radius of circular pattern, rotate swingle at last, utilize pencil to draw circular pattern; When drawing on the plate face, sucker is adsorbed on the plate face, what this moment, swingle contacted with the plate face is chalk, still regulates cross bar length, rotates swingle and just can draw circular pattern.When depositing, the user assigns into the pointer place to protective sleeve, avoids stabbing people's skin.
The utility model has the advantages that: rational in infrastructure, be widely used, moulding uniqueness, technology are simple, flexible operation, all can use on paper and plate face, and can guarantee user's safety, avoid the accident of stabbing.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the new-type compasses of the utility model.
The specific embodiment
As shown in Figure 1, the new-type compasses of the utility model comprise support bar 1, swingle 2 and cross bar 3, support bar 1 and swingle 2 keeping parallelisms, and cross bar 3 two ends are connected with both stage casings are vertical; Cross bar 3 sides of being bar shaped is divided into two sections, and two sections mutually nested, forms stretching structure; Support bar 1 top is provided with sucker 4, and pointer 5 is installed in the bottom; Swingle 2 tops are tubulose, and 2 axis direction symmetries are offered two openings 6 from the mouth of pipe along swingle, and chalk inserts in the mouth of pipe; At mouth of pipe place screw thread socket rotary sleeve 7; Swingle 2 bottoms connect pencil 8; Protective sleeve 9 is installed at pointer 5 places, and protective sleeve 9 is threaded with support bar 1; Two sections nested type cross bar 3 surfaces are provided with length scale 10.
