It is provided with the little gear being engaged with；The gear wheel, little gear, small belt pulley and big belt pulley are removably mounted to riser
Front end；The erecting bed upper end right side is provided with voice playing device；The erecting bed lower end is by the jack with pedal
It is connected with base, the base lower end is provided with multiple universal wheels.
As further program of the utility model：Brake gear is provided with the universal wheel.
As the utility model further scheme：Beam is provided between the riser and erecting bed.
Compared with prior art, the beneficial effects of the utility model are：When using, shaking small belt pulley by rocking handle makes it
Rotate, small belt pulley drives big belt pulley to rotate by belt transmissioning mode, and then drives the circle being coaxially disposed with big belt pulley
Plate is rotated, and because plectane and connecting rod and sliding block constitute slider-crank mechanism, therefore sliding block is moved left and right in chute periodically, band
The tooth bar for moving its upper end is moved left and right, and then drives the bull gear drive being engaged with, and gear wheel is further through the side of external toothing
Formula drives pinion rotation；Jack and pedal are set, and the height of the efficient and convenient regulation present apparatus meets different height students'
Operational comfort；Universal wheel, conveniently moving are set；Voice playing device is set, by speech sound eeplaining mechanism principle and attention thing
, deepen the understanding of student, it is ensured that safe operation.
In sum, this new structural design is rationally, easy to use, and being operated by students ' actual situation makes each mechanism kinematic,
More lively tool is as helping Students ' Learning memory；It is highly easy to adjust, meet the operational comfort of different height students；Pass through
Speech sound eeplaining mechanism principle and points for attention, further deepen the understanding of student, it is ensured that safe operation.
