Abstract
Provided is a compass, comprising a holder, a leg A and a leg B, wherein the compass leg A is provided with a sliding groove, and the leg B is provided with a fixed point. A movable connecting rod is provided, with one end connected to the fixed point and the other end connected to the sliding groove. The end connected to the fixed point is capable of rotating with the rod as the radius, and the end connected to the sliding groove has a movable screw and can slide or be fixed in the sliding groove. The compass employs the principle of trilateral stability and enables the connecting rod and the two compass legs to form a triangle, so that the radius can be accurately controlled during the drawing.
Description
Technical field: the utility model relates to a kind of compasses, belongs to stationery.
Background technology: there are compasses the market very much now, but these compasses in when mapping, radius is difficult to fix.
Technical scheme: for addressing the above problem, of the present utility modelly provide a kind of compasses that can radii fixus.
A kind of compasses, comprise handle, pin A and pin B, have sliding tray on the compass foot A, one fixing point is arranged on the pin B, a movable rod is arranged, an end is connected on the fixing point, the other end is connected on the sliding tray, an end that is connected in fixing point can be that radius rotates with the bar, and an end that is connected on the sliding tray has movable screw, can slide in sliding tray or fixes; Pin B inboard also has a groove that matches with connecting rod, and connecting rod was received in the groove just when bipod was drawn in.
This compasses are used the principle of triangle stability, make connecting rod and compasses bipod constitute triangle, thereby, accurate Control Radius when mapping.
Description of drawings:
Fig. 1: overall appearance figure;
Fig. 2: pin A stereogram;
Fig. 3: pin B stereogram;
Among the figure, 1 is handle, and 2 is pin A, and 3 is the connecting rod sliding tray, and 4 is movable rod, and 5 is pin B, and 6 is fixing point, and 7 is that movable screw groove, 8 is groove C.
The specific embodiment: a kind of compasses, there is handle 1 to be connected with pin A 2, pin B 3, pin A is equipped with pilot pin, pin B is equipped with pencil, having the inboard on the compass foot A has connecting rod sliding tray 3, the outside that movable screw groove 7 is arranged, one fixing point 6 is arranged on the pin B, one movable rod 4, length is greater than the distance of fixing point 6 to handle 1, one end of one movable rod 4 is connected on the fixing point 6, can be that radius rotates with the bar, the other end be connected in the connecting rod sliding tray 3, can control its slip or fixing by the movable screw of movable screw groove 7; Pin B inboard also has a groove C who matches with connecting rod, and connecting rod was received in the groove C just when bipod was drawn in.
