A power supply for providing electric energy is arranged in the storage cabinet.

As a further solution of the utility model: brake devices are provided on the universal wheels.

As a further solution of the utility model: a shock-absorbing pad is provided between the installation platform and the base.

As a further solution of the utility model: the large gear, the small gear and the large pulley can all be detachably mounted on the front end of the vertical plate.

Compared with the prior art, the beneficial effect of the utility model is: start the drive motor when in use, the drive motor drives the small pulley to rotate, the small pulley drives the large pulley to rotate through the belt transmission mode, and then drives the circular plate coaxially arranged with the large pulley Rotate, because the circular plate, the connecting rod and the slider constitute a crank slider mechanism, so the slider periodically moves left and right in the chute, driving the rack at the upper end to move left and right, and then drives the large gear meshed with it to rotate, and the large gear The gear drives the pinion to rotate through external meshing; a storage box is provided for storing the disassembled pinion, large gear and large pulley; a universal wheel is provided to make the device move easily; a power supply is provided to provide electric energy.

To sum up, the new model is simple in structure, practical and convenient. It can not only display various mechanical transmission mechanisms, but also drive the movement of each mechanism through the driving motor, making the explanation more vivid and concrete, and helping students learn and memorize; driven by a single driving motor, Reduce teaching costs.
