Abstract
The utility model relates to a pair of compasses, which comprises a compass base. A handle is arranged on the compass base; a fixed compass leg is fixedly connected to the middle of the compass base; the lower end of the fixed compass leg is connected with a locating pin; the left side and the right side of the compass base are respectively movably connected with a left movable compass leg and a right movable compass leg; the lower ends of the left movable compass leg and the right movable compass leg are respectively provided with a mounting hole in which a bolt bar penetrates; one end of the bolt bar is fixedly connected with a fixed drawing foot while the other end is connected with a locknut; the fixed drawing feet are respectively locked to the left movable compass leg and the right movable compass leg; the fixed drawing foot is connected with a movable drawing foot through the locknut; and the lower ends of the fixed drawing foot and the movable drawing foot are respectively connected with a lead core. The compasses are capable of conveniently drawing out four concentric circles directly at most, which are convenient.
Description
Technical field
The utility model relates to a kind of compasses, relates in particular to a kind of a plurality of concentrically ringed compasses that can conveniently draw.
Background technology
A fixedly picture pin is equipped with in the bottom of the moving rule leg of general compasses, once can only draw a circle, and the concentric circles that can not directly draw.
Summary of the invention
The purpose of this utility model provides a kind of a plurality of concentrically ringed compasses that can directly draw easily.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of compasses comprise: Circinus, handle is housed above the Circinus, and it is characterized in that: the center fixed of Circinus is connected with the set pattern leg, and the lower end of set pattern leg is connected with pilot pin; The left side of Circinus and right side are connected with a left side moving rule leg and right moving rule leg respectively; The lower end of a left side moving rule leg and right moving rule leg has been designed installing hole respectively, be installed with shank of bolt in the installing hole, one end of shank of bolt is fixedly connected with fixedly picture pin, and the other end of shank of bolt is connected with locking nut, and fixedly the picture pin is locked in respectively on a left side moving rule leg and the right moving rule leg; Fixedly be connected with the movable pin of drawing by locking nut on the picture pin; Fixedly picture pin and movable lower end of drawing pin are connected with lead for retractable pencil respectively.
The utility model a plurality of concentric circles that can directly draw easily, 4 concentric circles that can draw the most for a long time, the utility model is easy to use.
Description of drawings
Figure is a structural representation of the present utility model.
In the accompanying drawing: 1, handle; 2, Circinus; 3, right moving rule leg; 4, fixing picture pin; 5, the movable pin of drawing; 6, locking nut; 7, lead for retractable pencil; 8, pilot pin; 9, set pattern leg; 10, shank of bolt; 11, locking nut; 12, the moving rule in left side leg.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
A kind of compasses of the utility model comprise as shown in the figure: Circinus 2, handle 1 is housed above the Circinus 2, and the center fixed of Circinus 2 is connected with set pattern leg 9, and the lower end of set pattern leg 9 is connected with pilot pin 8.The left side of Circinus 2 and right side are connected with a left side moving rule leg 12 and right moving rule leg 3 respectively.
The lower end of a left side moving rule leg 12 and right moving rule leg 3 has been designed installing hole respectively, is installed with shank of bolt 10 in the installing hole, and an end of shank of bolt 10 is fixedly connected with fixedly picture pin 4, and the other end of shank of bolt is connected with locking nut 11.Fixedly picture pin 4 is locked in respectively on a left side moving rule leg 12 and the right moving rule leg 3; Fixedly be connected with the movable pin 5 of drawing by locking nut 6 on the picture pin 4.Fixedly picture pin 4 and movable lower end of drawing pin 5 are connected with lead for retractable pencil 7 respectively.
When the utility model uses, be the center of circle, fixedly picture pin 4 on a left side moving rule leg 12 and the right moving rule leg 3 and the movable pin 5 of drawing be adjusted to required separately radius and carry out the picture circle that 4 concentric circles can directly draw at most with the pilot pin 8 of Circinus 2 bottoms.
The utility model can also Circinus 2 bottoms pilot pin 8 be the center of circle, with certain fixedly picture pin or the movable pin of drawing lift, use the picture pin that does not the lift required concentric circles that draws.In addition, only stay one to draw pin and other are drawn pin lift, can singly draw a circle.
