Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.
One embodiment of the compass, as shown in fig. 1 and 2, includes: a compass body 10 and a sleeve 20.
The compass body 10 includes a first compass foot 12 and a second compass foot 14, one end of the first compass foot 12 is rotatably connected to one end of the second compass foot 14 via a rotating shaft (not shown), and the compass body 10 is closed or opened by the relative rotation of the first compass foot 12 and the second compass foot 14.
The other end of the first compass foot 12 is provided with a positioning pin 122, and the other end of the second compass foot 14 is provided with a pen head 142.
The sleeve 20 is internally provided with a containing cavity, the other end of the first compass foot 12 and the other end of the second compass foot 14 can be contained in the containing cavity when the compass main body 10 is closed, the outer surface of the sleeve 20 is provided with a linear area 22, and the linear area 22 is provided with scales.
The sleeve 20 of the compasses is provided with a linear area 22, the linear area 22 is provided with scales, so that the compasses has the function of a ruler, and when the compasses main body needs to draw a ruler with a specified size, the ruler can be directly measured on the linear area 22 of the sleeve 20.
The compasses are provided with the sleeve 20, are not matched with a ruler for use, and are convenient to use. In addition, the sleeve 20 also has the function of protecting the positioning pin 122 and the pen head 142, so that damage to the positioning pin 122 and the pen head 142 can be avoided, and the positioning pin 122 and the pen head 142 can be prevented from pricking a user or others.
With reference to the figures, in the present embodiment, the axis of rotation is perpendicular to the plane of rotation formed by the rotation of the first compass foot 12 relative to the second compass foot 14.
In this embodiment, a surface of the first compass leg 12 adjacent to the second compass leg 14 is a first plane, a surface of the second compass leg 14 adjacent to the first compass leg 12 is a second plane, and the first plane and the second plane are overlapped or laminated together when the compass body 10 is closed.
In the present embodiment, when the compass body 10 is closed, the first compass foot 12 and the second compass foot 14 form a rectangular prism shape, and the sleeve 20 is a matched rectangular prism shape.
In an embodiment thereof, the first and second compass legs 12, 14 may also be formed in a cylindrical or elliptical cylinder shape, with the sleeve 20 being a matching cylindrical or elliptical cylinder shape.
With reference to the drawings, in the present embodiment, the portion of the rotating shaft protruding out of the compass body 10 forms a projection 162, and the sidewall of the sleeve 20 is provided with a groove 24 matching with the projection 162.
