Computer software teaching demonstration table fixing device for informatization

Abstract

The invention provides a computer software teaching demonstration table fixing device for informatization. The computer software teaching demonstration table fixing device comprises a base; a two-waythreaded rod is rotationally connected into the front end of the lifting platform, the left end and the right end of the two-way threaded rod are in threaded connection with a left vertical plate anda right vertical plate, and the left vertical plate and the right vertical plate are rotationally connected with a left side plate and a right side plate correspondingly. A hand crank is rotatably connected to the middle of the rear side wall of the lifting platform, and the hand crank is in engaged connection with the transmission rod; a demonstration board is inserted between the left side boardand the right side board. A ratchet wheel bolt is slidably connected to the middle of the left side wall of the left vertical plate; the ratchet plug pin is pulled upwards to enable the top of the ratchet plug pin to compress the reset spring, and when the rotating cap at the top of the ratchet plug pin is higher than the ejector rod at the top of the protective shell, the rotating cap is rotatedto be in lap joint with the top of the ejector rod, so that the demonstration board can be rotated at will, and reset adjustment of the demonstration board is facilitated; and the demonstration boardcan be rapidly fixed to a needed overturning angle.
