Abstract

The invention discloses a teaching board fixing device for college student training, which comprises a connecting block, a swing rod, a movable seat, a fixed plate, a clamping rod, a groove, a lifting mechanism and a limiting mechanism, and is characterized in that the lifting mechanism is arranged at the upper end of the fixed plate, and a top plate is pulled, so that an included angle between a first movable rod and a second movable rod is reduced; a first sliding block and a second sliding block are made to slide, meanwhile, a reset spring is pulled to deform, so that a top plate is lifted, then a teaching board can be placed at the upper end of a fixing plate, pulling of the top plate is released, and the top plate is driven to the lower end to fix the teaching board through elastic potential energy of deformation recovery of the reset spring; the advantage that the teaching board can be rapidly installed and fixed is achieved.

Description

technical field [0001] Specifically, the invention relates to a teaching board fixing device for college students' training, and relates to the related field of teaching boards. Background technique [0002] The teaching board is the utensil used for writing demonstrations in the education industry. Usually, the teaching board is a board placed in a classroom or a conference room. The content is written with chalk or water-based pen, which plays the role of explaining and demonstrating, and is widely used. [0003] During the training of college students, it is often necessary to fix the teaching board. At this time, a fixing device is needed. The current fixing device is generally simple in structure and needs to use a specific device to fix the teaching board, resulting in time-consuming and laborious fixing. Contents of the invention [0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a teaching board fixing device for ...
