Description
technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a lifting device with stable lifting. Background technique [0002] During the actual use of the lifting column, the force used for the rotation is affected by the size of the handle and the weight of the supporting weight. The rotation is uneven and the operation of the lifting column is not stable. In the process of use, it is necessary to rely on perception to judge whether the lifting structure has reached the upper and lower limits, and the paper guide screw appears to be idling and over-rotating. It is easy to cause irreversible damage to the structure. For example, Chinese patent CN110861735A, published on March 6, 2020, is a lifting column that reduces corrosion and is convenient to adjust, including a body. The interior of the body is provided with an inner groove 1 and a moving groove, and the inner pipe is provided with an inner groove 2. , the inside of th...
