Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Embodiment 1
As shown in Figure 1 to Figure 3, the present embodiment multifunctional ruler includes main scale 1, secondary chi 2 and rotating shaft 3, in the inside of main scale 1
Sky, the dead slot 11 of main scale 1 can accommodate secondary chi 2, and main scale 1 and secondary chi 2 are located to be connected by rotating shaft 3 therebetween；Rotating shaft 3 and secondary chi 2
It is fixedly connected and is rotated with the rotation of secondary chi 2, one end of rotating shaft 3 passes the surface of main scale 1 and is fixedly connected in the termination
There is pointer 4；The surface of main scale 1 is provided with the angle scale 12 of circle, and angle line, angle scale 12 and rotating shaft are imprinted with angle scale 12
3 is concentric.
The middle part of the main scale 1 is provided with a screwed hole, and lock-screw 5, rotational lock screw 5 are provided with screwed hole
Rotating shaft 3 can be pressed and then the relative position of main scale 1 and secondary chi 2 is locked.
The obverse and reverse of the main scale 1 and secondary chi 2 is provided with graduation mark, and the front of main scale 1 and secondary chi 2 is imprinted with general
The reverse side of the graduation mark of logical ruler, main scale 1 and secondary chi 2 is imprinted with two graduation marks of reference axis of rectangular coordinate system respectively.
The present embodiment multifunctional ruler can be made using plastics, metal or wood materials, and predominantly middle and primary schools' teaching makes
With its major function includes：(1) used as ruler, secondary chi 2 is accommodated in the dead slot 11 of main scale 1；(2) as angle
Degree chi is used, and secondary chi 2 is screwed out from the dead slot 11 of main scale 1, and rotating shaft 3 and pointer 4 rotate with the rotation of secondary chi 2, refer to
Pin 4 points out the angle between secondary chi 2 and main scale 1 on angle scale 12, when pointer 4 points to predetermined angle, screws locking screw
Nail 5；(3) used as protractor, secondary chi 2 screwed out from the dead slot 11 of main scale 1 so that main scale 1 and secondary chi 1 respectively with it is to be measured
Two sides at the angle of amount overlap, and the pointed angle on angle scale 12 of pointer 4 is the size at angle to be measured；(4) simulate
Plane right-angle coordinate, secondary chi 2 is screwed out from the dead slot 11 of main scale 1, is mutually perpendicular to main scale 1 and secondary chi 2, by the He of main scale 1
Towards upper, plane space is divided into four quadrants to the reverse side of secondary chi 2 by main scale 1 and secondary chi 2.
Although being illustrated to implementation method of the present utility model in specification, these implementation methods are intended only as carrying
Show, should not limit protection domain of the present utility model.Carried out in the range of the utility model objective various omissions, put not departing from
