With the popularization and development of computer technology, more and more people work or learn through computers. The computer brings convenience to work and life of people and brings negative effects to people, people frequently suffer from occupational diseases such as cervical spondylosis, lumbar spondylosis and the like due to the fact that people use the computer for a long time and sit in front of the computer, and more people put forward the concept of healthy working and learning.

Research shows that if people adopt sitting posture and standing posture to work alternately, modern occupational diseases such as cervical spondylosis and lumbar spondylosis can be well prevented, and therefore lifting office tables appear on the market to meet the needs of people for working alternately in sitting posture and standing posture.

On the basis, a lifting table is available in the market, the lifting table can be used after being placed above an existing office table or other supports, related office products such as computers and the like are placed on the lifting table, and when a user works in a sitting posture and a standing posture alternately, the height of the lifting table is adjusted to adapt to the change of the posture of the user.

In the current market, power elements used by the lifting table are basically air springs or accessories such as tension springs, and the size of lifting power of the lifting table is fixed and unadjustable, and only can meet the fixed load range in design. For example, in a lifting table using a gas spring as a power element, the lifting table can automatically rise at a constant speed by toggling a switch within a designed load range; but when the load exceeds the design range, the lifting is weak, and extra lifting is needed, so that the user experience is poor. When the load of the lifting table is insufficient, the lifting table can automatically and quickly lift by toggling a switch, so that objects on the table top can easily fall off, and the lifting table is unsafe to use; when the table is too heavy, the user needs to lift the table additionally, and the user experience is poor.
