Furthermore, two sides of the main board are set to be arc-shaped.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the movable bolt is connected to the long empty groove of the main board, so that a worker can conveniently adjust a proper distance in the drawing process, can freely slide in the using process, and can fix a contact pin or a painting brush at a certain length position through the fixing action of the bolt and a nut to obtain the radius of an arc to be measured;

2. the contact pin is fixedly connected to the left side of the main board, so that the circle center of the compasses is fixed in the use process, and the main board is rotated around the circle center point to draw a required radius;

3. the left contact pin is higher than the right contact pin in height, so that the left contact pin can be better fixed on a material for drawing a great circle;

4. the handle is arranged on the other side of the main board for fixing the left contact pin, and the handle is held by hand to fix the circle center and the whole structure of the sliding compasses in drawing, so that the drawing accuracy is improved;

5. the utility model discloses structural design is simple, makes things convenient for the workman to draw and removes, and the centre of a circle location is firm.
