A telescoping leg assembly with a pivot apparatus having a first and second telescoping leg, each with an extension section and a sleeve component, the sleeve component divided longitudinally into a first space and second space. The leg extension sections are dimensioned to retract into and telescope from the first space in the first leg sleeve component. The telescoping legs are pivotally attached to one another by a pivot apparatus on the sleeve portions, wherein the pivot apparatus extends into the second spaces of the sleeve components.

The present invention discloses a folding table that can be quickly increased in height, including a first table leg and a second table leg arranged oppositely. The bottom end of the first table leg is provided with a first adjustment bar that can flip to achieve height adjustment, and the bottom end of the second table leg is provided with a second adjustment bar that can flip to achieve height adjustment. By simply flipping the first adjustment bar and the second adjustment bar outward simultaneously to a vertical state, the foldable leg frame can quickly increase in height. Additionally, by providing a locking mechanism, the stability of the folding table is further enhanced.

An elevation working platform includes a lower support and an upper support. At least one group of X-type elevation mechanisms is provided between the lower support and the upper support. The elevation working platform further includes an elastic element. A first end of the elastic element is connected between two end points of a first support rod or a second support rod. A second end of the elastic element is connected to the lower support or a second hinging seat capable of sliding relative to the lower support. Using the X-type elevation mechanisms, the front and back positions of the upper support do not change in an elevating process of the upper support, the structure is simple and practical, and the cost is relatively low.
