According to the multifunctional desk provided by the invention, articles at the upper end of the desk can be prevented from dropping via the baffle plate; the placing box is used for placing books; the sliding block can slide in the sliding groove; the articles areplaced into the desk body and a rotary block is rotated, so that the upper end of a clamping block is clamped on the desk body and the desk body is sealed so as to prevent the articles in the desk body from dropping out; and a rotating shaft can be driven to rotate via a rotary disc, and the rotary disc can slide leftwards and rightwards on the rotating shaft.

Description

technical field [0001] The invention relates to a teaching device, in particular to a multifunctional desk for teaching which is easy to adjust the height. Background technique [0002] At present, the height distribution range of students of the same age is large, which is reflected in the classroom, and the requirements for the height of the desks are also very different; but most of the desks used now are produced uniformly, with the same height and cannot be adjusted. Students' schoolwork burden is getting heavier, students' books, materials, etc. are increasing, and students' schoolbags are getting heavier; reflected in the school, the space provided by desks is far from meeting the needs of students.

[0002] At present, the height distribution range of students of the same age is large, which is reflected in the classroom, and the requirements for the height of the desks are also very different; but most of the desks used now are produced uniformly, with the same height and cannot be adjusted. Students' schoolwork burden is getting heavier, students' books, materials, etc. are increasing, and students' schoolbags are getting heavier; reflected in the school, the space provided by desks is far from meeting the needs of students. In order to be able to place books, For learning materials such as test papers, students have to pile things on the table or put them on the ground. The former will affect the cleanliness of the classroom and students' sight of the blackboard, while the latter will make things dirty and it is not convenient to clean the classroom. The placement box is generally open, and the things put in are easy to fall, so there is an urgent need for a device to solve the above problems
