The utility model relates to a cantilever structure which comprises a lifting device, a pivoted shaft and a connecting component. An elastic body is arranged between an inner sleeve barrel and a telescoping rod, an outer rotating barrel is combined with the inner sleeve barrel, an opening on the top part and the top margin of the inner sleeve barrel have clamp rings, the outer rotating barrel is arranged outside the inner sleeve barrel and can rotate to exert radial pressure to the clamp rings, the stricture or the release is generated to a telescopic rod and the telescopic rod is arranged at the top part of the outer rotating barrel and can be lifted. The center of a shaft connection seat is provided with a shaft trough, clamp forcing rings are abutted with the inner sides of extended piece wings on both sides of a clamp frame, the shaft connection seat is in the sleeve connection between clamp forcing rings, a supporting shaft which is extended out of the top part of the telescopic rod penetrates through the two piece wings and the shaft connection seat between the telescopic rods, and the shaft connection seat is combined with the supporting shaft through a connection piece to clamp and force the shaft connection seat together and the clamp frame can rotate. The connection component is combined with the clamp frame and is connected with supporters which are supported through the connection component, the height is adjusted by the lifting device and the pivoted shaft is taken as the transformed direction. |
