Desktop adjustment structure improvement (1)

This creation department is about a kind of "desktop adjustment structure improvement (1)", especially a kind of main table that can be pivoted and can avoid the table with the gap between people and the desktop structure.

Press, the common desks and desks have a fixed design on the desktop, so it is not suitable for users with different body shape or writing and reading habits, especially in the development of school-age children, their body type will change constantly. If the desktop angle cannot be adjusted, it will affect its practical value.

In order to solve such problems, although the manufacturer has developed a design with adjustable angle of the desktop, the main desktop has a gap with the sub-desktop before and after the main desktop, and the gap is easy to cause a pinch on the user's finger when the main desktop is lowered. It is relatively unsafe.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional desktop adjustment structure is actually the goal of the relevant industry to develop and research. The creator has the idea of thinking and creation, and has many years of experience. The design, the multi-party discussion and trial sample test, and many corrections and improvements, is the launch of this creation.

It is easy to pinch the user's finger when the main table is lowered, which is the technical problem to be solved.
