Description

The present invention takes up the field of stationery and is specifically a multifunctional writing desk.

When studying or working, people use a writing desk, and sometimes due to work, they install dividers around the writing desk to protect their privacy, but attaching dividers is a space on the desk surface. It seems that the space on the desk surface is crowded, which sometimes affects study and work, so it is really necessary to design a multifunctional writing desk that can store the partition plate and can be raised and lowered. This device can raise the divider, provide a relatively closed study and work environment, protect personal privacy, and the divider can be stored under the desk surface, taking up other space. It is not possible to raise and lower the desk surface and store the partition plate at the same time in order to improve usability and ensure safety because the desk surface can be raised and lowered according to individual demand.
