Abstract
The utility model relates to a novel compass, which comprises a cross rod with scale marks and is characterized in that one end of the cross rod is hinged on a longitudinal short rod of which the end part is provided with a positioning component, while the other end thereof is in sliding connection with a drawing component. The novel compass has the advantages of simple structure, simple and convenient use process, accurate positioning, good drawing effect and no damage to drawing paper.
Description
Technical field
The utility model relates to compasses, particularly a kind of novel bow compass.
Background technology
Common all compasses generally include a handle and all two legs that links to each other with handle now.One leg all end is a needle point, in addition one leg all the end be drawing pen nib.During use two legs is separated into required radius, needle point is fixed in the center of circle, pinches handle rubbing rotation and makes drawing pen nib draw camber line along radius.
Common compasses have been used for many years, and still there are shortcoming in its structure and use.When increasing for example between two legs when drawing big figure, two legs and drawing plane all gradient increase, so handle is wayward to needle point or all suitable dynamics of drawing pen nib.And in drawing process, needle point damages paper easily, perhaps fixing needle point on blackboard, locate inaccurate, thereby bring very big inconvenience and draw effect bad again to drawing process.Therefore, how addressing the above problem is research object of the present utility model.
Summary of the invention
It is a kind of easy to use that the purpose of this utility model is to provide, and effective novel bow compass is drawn in accurate positioning.
Of the present utility model being characterised in that: a kind of novel bow compass, comprise cross bar with graduation mark, it is characterized in that: described cross bar one end is hinged on the end to have on vertical quarter butt of keeper, and the other end slidely connects the drawing assembly.
Advantage of the present utility model: the utility model is simple in structure, and use is simple, convenient, and accurate positioning is drawn effectively, and does not damage drawing paper.
Description of drawings
Fig. 1 adopts the structural representation of sucker for the utility model keeper.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 adopts the structural representation of needle for the utility model keeper.
Fig. 4 adopts the structural representation of thimble for the utility model keeper.
Fig. 5 adopts the structural representation of magnetic patch for the utility model keeper.
The specific embodiment
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of novel bow compass comprises the cross bar 1 with graduation mark 2, and described cross bar 1 one ends are hinged on the end to have on vertical quarter butt 4 of keeper 3, and the other end slidely connects drawing assembly 5.
Above-mentioned drawing assembly 5 comprises hitch 5-1 and the handle 5-2 that is slidingly connected with cross bar 1, and described handle 5-2 bottom is connected with inner hollow and in order to install the pen cap 5-3 of nib, described pen cap 5-3 is connected with hitch 5-1 through bolt 5-4.
Above-mentioned vertical quarter butt 4 pins cross bars 1 by nut 6, prevents that cross bar 1 from running out of vertical quarter butt 4.
The keeper 3 of above-mentioned vertical quarter butt is a sucker, thimble, and needle or magnetic patch are selected suitable keeper for use according to concrete occasion, thereby realize complete drawing.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
