Preferably, the rectangle body of rod that described keeper is bottom is pyramidal structure or the cylindrical body of rod.
Preferably, described angle measuring scale and rotary ruler are carved with length scale line and angle index line respectively, and the zero graduation line of described angle index line is concordant with main scale top.
Preferably, be provided with elastic ring in described chalk sleeve, described elastic ring is rubber ring or elastoplast circle.
Preferably, described slide block is carved with the lubber-line of the length scale line be used to indicate on main scale.
Preferably, described connector is run through the connecting rod of chalkboard eraser right-hand member or projection integrated with chalkboard eraser.
Compared with prior art, the beneficial effects of the utility model are: this Multifunctional mathematics teaching ruler, coordinated the angle that teacher can be facilitated to draw and measure different angles with angle measuring scale by rotary ruler, this Multifunctional mathematics teaching ruler coordinates the circle can drawing different-diameter with sliding shoe by keeper, this Multifunctional mathematics teaching ruler is provided with chalkboard eraser structure, the quantity that teacher carries teaching aid can be reduced, this Multifunctional mathematics teaching ruler, sucker is provided with, the phenomenon that during for preventing teacher from drawing on blackboard, teaching ruler slides at the main scale back side.
Accompanying drawing explanation
