Novel teaching desk bench

The utility model provides a simply-structured novel teaching desk bench with convenient use and aims to solve a problem that a desk and a bench cannot be instantly moved and re-arrayed. The novel teaching desk bench comprises two sets of double-desk and double-bench. The bottommost part of the desk bench is provided with a fixed pulley; guide rails are paved on the ground; desk legs are connected with external chains; bench legs are connected with internal chains; point moving directions of two chains between chain wheels are opposite, so the desk and the bench can be fastened on the two points and the desk and the bench can move toward different directions; and the movement is simultaneous, opposite and at equal distance. Therefore, the desk and the bench can be interchanged via two chain transmission mechanisms; desk and bench instant movements can be achieved, so time can be saved and fewer noises are made; and a class mode is transferred from teacher teaching to student discussion.
