Abstract

The invention relates to a teaching desk, in particular to a teaching desk with a variable desktop area. The technical problem of the invention is how to design the teaching desk with the variable desktop area, so that the book placing area can be changed, more books can be placed, and convenience is achieved. The teaching desk comprises a frame body, wherein supporting plates are symmetrically and fixedly connected to one side outside the frame body; and a table plate which is fixedly connected to the side, away from the supporting plate, of the exterior of the frame body. The rotary knob ispulled to move forwards to be separated from the frame body, then the rotary knob is twisted to rotate reversely, the reel rolls up the pull wire, the pull wire rolls up to drive the u-shaped guide plate to move outwards, the u-shaped guide plate drives the n-shaped push plate to move outwards, the u-shaped push plate drives the swing plate to swing upwards by 90 degrees, the rotary knob is loosened to reset, and a book can be placed on the swing plate; therefore, more books can be placed.

Description

technical field [0001] The invention relates to a teaching desk, in particular to a teaching desk with a variable desktop area.
