Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a high-precision foot assisting compasses comprises a bearing 1, a pen clip 2, a pen point clip 3, a pen point 4, a long screw 5, a plurality of long pins 6, three springs 7, three short pins 8, three hinges 9, three wheels 10, three screws 11, three screw caps 12, a cap 13, three upper foot frames 14, an upper main shaft 15, three lower feet 16, a lower main shaft 17, three pins 18, a compasses cover 19, a scale bar 20 and three spring pads 21.

The bearing 1 is directly sleeved on the lower main shaft 17, the lower main shaft 17 is connected with one end of the upper main shaft 15, and the other end of the upper main shaft 15 is in rotary threaded connection with the cap 13 through a compass cover 19; one end of each of the three upper foot rests 14 is connected with the compasses cover 19 through a short pin 8 to realize the fixation of the main body; the other end of each upper foot rest 14 is connected with one end of a lower foot 16 through a long pin 6, one end of each hinge 9 is connected with the lower foot 16 through the long pin 6, and the other end of each hinge 9 is connected with the bearing 1 through a screw 11, so that the stable rotation of the compasses is realized; the other end of each lower leg 16 is fixed with the pen clip 2 through a long screw 5 and a nut 12, so that the drawing effect is realized.
