- a telescopic adjustment member 400, wherein a first end of the telescopic adjustment member 400 is hinged to the first supporting assembly 110; a second end of the telescopic adjustment member 400 is hinged to the second supporting assembly 120; the telescopic adjustment member 400 extends and retracts between a retraction length and an extension length to drive relative rotation between the first supporting assembly 110 and the second supporting assembly 120; and
- a damping member 500, wherein a first end of the damping member 500 is hinged to the first supporting assembly 110; a second end of the damping member 500 is hinged to the second supporting assembly 120; and the damping member 500 provides a damping force to hinder the relative rotation between the first supporting assembly 110 and the second supporting assembly 120.

By the arrangement of the above structure, during use, a length of the telescopic adjustment member 400 is adjusted. The first supporting assembly 110 and the second supporting assembly 120 can change an angle between the first supporting assembly 110 and the second supporting assembly 120. The second end of the first supporting assembly 110 slides relative to the base 300, and the second end of the second supporting assembly 120 slides relative to the first desk board 200, to change the overall height of the height-adjustable desk. Meanwhile, the damping member 500 increases a damping force to change the length of the telescopic adjustment member 400 slowly and uniformly. This prevents a situation of falling and damage of office items such as a computer due to quick changes in the height of the supporting frame 100. Moreover, a user adjusts the height more smoothly. It is more convenient to use the height-adjustable desk.
In this embodiment, the telescopic adjustment member 400 is a pneumatic spring; the pneumatic spring is provided with a cylinder 410 and a piston rod 420; the piston rod 420 is connected to a piston; and air in the cylinder 410 drives the piston to slide, so as to drive the piston rod 420 to slide relative to the cylinder 410. By the arrangement of the above structure, during use, compressed air in the pneumatic spring cylinder 410 drives the piston, and then drives the piston rod 420, thereby changing the length of the telescopic adjustment member 400. Meanwhile, the pneumatic spring further plays a supporting role, which can effectively support the first supporting assembly 110 and the second supporting assembly 120 to fix the height of the height-adjustable desk.
In this embodiment, the height-adjustable desk with the damping device further includes a switch device 600. The switch device 600 is connected to the pneumatic spring and adjusts an air pressure in the cylinder 410. By the arrangement of the above structure, during use, the switch device 600 is turned on to adjust the air pressure in the cylinder 410 to communicate with an external atmosphere. A desktop is raised. The first supporting assembly 110 and the second supporting assembly 120 rotate relative to each other, thereby driving the height-adjustable desk to rise or fall. When the height-adjustable desk rises to an appropriate position, the switch device 600 is released.
