Abstract

The invention provides a multifunctional information management teaching device, which comprises a bottom plate, moving wheels, telescopic pipes, a telescopic rod, a U-shaped frame, a connecting rod,a protection plate, a placement plate, a rotatable fixing seat structure, a projection writing board structure, an auxiliary supporting frame structure, a movable cleaning frame structure, a shell, astorage battery and a driving switch. The moving wheels are installed on the periphery of the lower surface of the bottom plate through bolts. The telescopic pipes are welded to the left side and theright side of the upper surface of the bottom plate correspondingly. The telescopic rods are welded to the left side and the right side of the lower end of a U-shaped frame correspondingly, the telescopic rods are inserted into the telescopic pipes, and meanwhile the connecting positions of the telescopic rods and the telescopic pipes are fixed through bolts. The device has the beneficial effectsthat through the arrangement of a rotatable fixing seat structure, a clamping plate is contracted under the action of external force during rotation, so that the clamping plate can be clamped throughthe clamping teeth for fixed use when the clamping teeth rotate or do not rotate, and then the clamping plate can be conveniently rotated and fixed at a specified angle for use.
