Surface is provided with gear grooved close to the side of ruler, and gear grooved is interior to be fixed with block plate by fixed column, and block plate diameter, which is greater than, to be fixed
Column diameter, and fixed column is fixedly connected with the center of block plate, gear is rotated by the turntable slot that the internal section being arranged is T shape
It covers on block plate, gear is freely rotated on block plate, gear is meshed with the gear teeth of arc-shaped slide rail, and the surface of gear is set
It is equipped with eight diagram-shaped pattern, cambered way drawing square above the opening of ruler is provided with angle indicator, gear teeth top
Drawing square surface be provided with the knob slot being recessed inwardly, the drawing square of knob groove center is embedded with inner screw sheath
Cylinder, inner thread sleeve inward turning are screwed with the fixing bolt that bottom sides are close to arc-shaped slide rail.
The utility model serves not only as set square, and can also be used to the angle of the certain degree of picture, preferably suitable
Mathematics drawing needs are answered, in the drawing processes for carrying out certain angle, rotation ruler can be rotated by gear teeth band moving gear, from
And with the eight diagram-shaped pattern rotation on moving gear, enhance the attraction to student, improves the mathematics drawing interest of student, facilitate
Improve the efficiency of student's learning mathematics；It is fixed with pen tool sleeve on right-angle side below drawing square, can be used for having in pen and insert
To clipping in pen tool sleeve, convenient for directly being had using pen when mathematics drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the folded state of the utility model；
Fig. 2 is the structural schematic diagram of the opening state of the utility model；
Fig. 3 is the cross section structure schematic diagram of the utility model gear, fixing bolt position.
Specific embodiment
As shown in Figure 1-3, a kind of mathematics plotter, including drawing square 1 and ruler 2, the shaft of 2 one end bottom of ruler
3 are inserted between the clamping plate 4 at 1 right angle position of drawing square, and the other end of ruler 2 is bevel edge, and ruler 2 is in the closure state
Drawing square 1 and ruler 2 form a bigger drawing square, and the surface of drawing square 1 is provided with the arc being recessed inwardly
Shape slideway 5, and the center of circle of cambered way 5, on the axle center of shaft 3, arc-shaped slide rail 6 is fixed on the side of ruler 2, and arc is sliding
Rail 6 is inserted in cambered way 5, is arranged angled on arc-shaped slide rail 6, and the gear teeth 7 are uniformly placed on the medial surface of arc-shaped slide rail 6,
1 surface of drawing square is provided with gear grooved 8 close to the side of ruler 2, passes through fixed column 9 in gear grooved 8 and is fixed with block plate 10,
10 diameter of block plate is greater than 9 diameter of fixed column, and fixed column 9 is fixedly connected with the center of block plate 10, and gear 11 is set by inside
The section set is the turntable slot turning set of T shape on block plate 10, is rotated on block plate 10 for the ease of gear 11, the two of block plate 10
The settable ball with 11 internal side wall joint of gear in face, gear 11 are meshed with the gear teeth 7 of arc-shaped slide rail 6, gear 11
Surface is provided with eight diagram-shaped pattern 12, and angled finger is arranged in the drawing square 1 above the opening of ruler 2 of cambered way 5
1 surface of drawing square of needle 13,7 top of the gear teeth is provided with the knob slot being recessed inwardly, the drawing square 1 of knob groove center
