The purpose of this utility model realizes by following technical proposal: a kind of Multifunctional mathematics teaching ruler, it is characterized in that: comprise the identical housing of outer contour shape one and housing two, pulley is connected with by rotating shaft is rotatable between described housing one and housing two, and described pulley is with described shaft axis Rotational Symmetry, described housing one is provided with displacement transducer, pressure transducer and display screen, described displacement transducer is connected with pressure transducer, displacement transducer described in driving during described pressure transducer pressurized and display screen work, and described display screen can show the distance of institute's displacement sensors motion, described housing two is provided with blade of carving knife.
During use, displacement transducer to be alignd one end of line segment to be measured, squeeze pressure sensor drives displacement transducer and display screen work, displacement transducer slides along line segment and measures by slip pulley, the distance that can be shown displacement transducer motion by display screen is the length of line segment, and therefore this teaching ruler can measure irregular line segment; And housing two is provided with blade of carving knife, also can use blade, therefore this teaching ruler serves many purposes; When not in use, also both can be made to close up along rotating shaft rotary shell one or housing two, be convenient to storage.
Drive the distance that displacement transducer and display screen work and display screen can show displacement transducer motion to be in addition during pressure transducer pressurized and adopt existing circuit structure.
In above-mentioned a kind of Multifunctional mathematics teaching ruler, described housing one is provided with chute one and shifting block one, described housing two is provided with chute two and shifting block two, described displacement transducer and blade can be placed in described housing one and housing two respectively completely, described shifting block one is connected with displacement transducer, and shifting block one can slide along chute one length direction and drive displacement transducer to stretch out housing one, described shifting block two is connected with blade, and shifting block two can slide along chute two length direction and be with cutting blade to stretch out housing two.
When not using, by housing one and housing two safeguard bit displacement sensor and blade.
In above-mentioned a kind of Multifunctional mathematics teaching ruler, described housing one and housing two are respectively equipped with Anti-skid sheet one and Anti-skid sheet two, and described Anti-skid sheet one is along shaft axis Rotational Symmetry, described Anti-skid sheet two is along shaft axis Rotational Symmetry.
Therefore thumb and forefinger divide don't push by Anti-skid sheet one and Anti-skid sheet two, with the pulley that slides.
Compared with prior art, the utility model tool has the following advantages:
During use, displacement transducer to be alignd one end of line segment to be measured, squeeze pressure sensor drives displacement transducer and display screen work, displacement transducer slides along line segment and measures by slip pulley, the distance that can be shown displacement transducer motion by display screen is the length of line segment, and therefore this teaching ruler can measure irregular line segment; And housing two is provided with blade of carving knife, also can use blade, therefore this teaching ruler serves many purposes; When not in use, also both can be made to close up along rotating shaft rotary shell one or housing two, be convenient to storage.
