Abstract

The invention relates to a desk, in particular to a height and angle adjustable student desk. The technical problem is how to design a height and angle adjustable student desk which does not need to waste a large amount of wood, is durable, and facilitates height and angle adjustment of people. The height and angle adjustable student desk comprises two bottom plates, wherein a first vertical plateis arranged at one side of each bottom plate; a transverse plate mounted between the two first vertical plates; a height adjusting device mounted on the first vertical plates and used for adjusting the height; an angle adjusting device installed on the height adjusting device and used for adjusting the angle. According to the desk, the height adjusting device is pulled to a proper position according to self requirements, then the height adjusting device is twisted to operate for fixing, and then the angle adjusting device is twisted to operate to a proper angle according to requirements, so that people can conveniently adjust the height and the angle of the desk.

Description

technical field [0001] The invention relates to a desk, in particular to a desk for students whose height and angle can be adjusted. Background technique [0002] Desks used by students, from the earliest octagonal desks in schools, are used in schools, and the desks used in schools should be unified as desks.
