Description

technical field [0001] The invention relates to a school desk, in particular to a four-leg synchronous lifting desk used by students. Background technique [0002] Desks are necessary equipment for schools. At present, most desks do not have a lifting function. A small number of desks with lifting function use bolt cutting device to realize lifting. The liftable desk with the bolt cutting device is fixed with screws and nuts on the front legs of the desk, allowing the school to do the adjustment work. But most schools don't pay much attention to this problem, and often only adjust it once when buying it, and rarely touch it later. The correct approach should be to adjust the height of the desks every semester according to the growth and development of different students. And the convenience and succinctness that the desk can be lifted is a big problem that the desk is facing at present. From the first grade to the sixth grade of elementary school, the body of the studen...
