Preferably, the inner wall both sides of the Circular Plate have been fixedly connected with spring, and the one end of spring far from Circular Plate It is fixedly connected with arc panel.
Preferably, the surface pivots of the set square are connected with swivel plate, and the bottom of swivel plate is fixedly connected with suction Disk.
Preferably, the top of the threaded rod is fixedly connected with handle, and the side of Circular Plate is fixedly connected with pointer.
Preferably, the surface of the semi-circle ruler is fixedly connected with semi-circular plate, and the surface of semi-circular plate is lived by movable axis It is dynamic to be connected with shell.
Preferably, the side of the shell is connected with pulling plate, and the side of pulling plate is fixedly connected with handle.
Advantageous effect
The utility model provides a kind of primary school's multifunctional plotter.Has following advantageous effect:
(1), primary school's multifunctional plotter, by being fixedly connected with semi-circle ruler in the upper surface of set square, set square Surface is fixedly connected with the Circular Plate that can fix chalk, and the use function of multiple plotters is gathered on a plotter, Not only can work as set square, but also compasses can be regarded and used, can also easily carry out it is circular draw, use is very convenient.
(2), primary school's multifunctional plotter, by being connected with swivel plate in the surface pivots of set square, swivel plate Surface is fixedly connected with sucker, and when carrying out picture circle, the center of circle can be determined using sucker, and sucker can improve stability, Chalk can be stuck in Circular Plate when drawing circle, it is only necessary to which rotation can draw circle, alleviate the burden of teacher.
(3), primary school's multifunctional plotter, by being connected with pulling plate in the surface activity of semi-circle ruler, pulling plate can be The surface measurement angle of semi-circle ruler need not utilize bevel protractor to go to measure the angle for needing picture, directly utilize semi-circle ruler It is drawn, simplifies the mode at picture angle, use is more convenient.
