Abstract
The utility model relates to a drawing compass, in particular to an accurate labor-saving drawing compass, which is characterized in that the utility model comprises a fixing rod, a handle, a bracket,a clamping piece, a sliding piece and a fixing cone, wherein the fixing rod is arranged in the middle of the bracket; the handle is arranged at one end of the fixing rod opposite to the bracket; thefixing cone is arranged at one end of the fixing rod opposite to the handle; the sliding piece is arranged at any one of both ends of the bracket divided by the fixing rod; the clamping piece is arranged on one side of the sliding piece parallel with the fixing rod; and the fixing cone is arranged on the fixing rod corresponding to the other end of the handle. The handle is wide and large, therebythe handle can be firmly held. When a circle is drawn, the utility model shakes to draw the circle accurately, the radius of the circle can be adjusted by scales, any pen can be clamped by the clamping piece, and old pencil leads do not need.
Description
Technical field
The utility model relates to a kind of picture compasses, relates in particular to a kind of accurate labour-saving picture compasses.
Background technology
At present general practical compasses use very inconvenient, draw circle and will aim at the good radius of ruler amount earlier, are difficult to adjust, and require great effort very much drawing bowlder, and the turning handle of existing original compasses more carefully is not easy to take and holds, and draw the bowlder hand and exert oneself that inhomogeneous will to justify picture easily inclined to one side.
Summary of the invention
The technical problem that solves:
The utility model provides a kind of laborsaving compasses.Solve above-mentioned described existing compasses and drawn the bowlder effort, drawn problems such as inclined to one side easily.
The utility model provides following technical scheme technical solution problem:
The utility model provides a kind of laborsaving compasses, comprise and decide bar, handle, support, intermediate plate, slide plate, fixed awl, describedly decide bar at the middle part that support is set, handle is arranged on an end of deciding bar of relative support, and fixed awl is arranged on the end of deciding bar with respect to handle, and slide plate is arranged on by on any end of two sections deciding the support that bar tells, intermediate plate is arranged on slide plate and is parallel to a side of deciding bar, and fixed awl is arranged on deciding on the bar with respect to the handle other end.
Laborsaving compasses described in the utility model, also comprise the described supporting pad of supporting pad be arranged on relative slide plate another section of support the top and downward vertically in support.
Laborsaving compasses described in the utility model comprise that also the described slide plate of fixed knob is provided with fixed knob.
Laborsaving compasses described in the utility model, described support are provided with on a section of slide plate scale are set.
Laborsaving compasses described in the utility model, described support is collapsible.
Beneficial effect
The utility model handle is roomy, takes the power of possessing to draw bowlder rolling animation circle accurately, and scale can be regulated radius of a circle, and intermediate plate can press from both sides any pen, need not to use old-fashioned pencil-lead.
