Telescopic scaffold

The invention provides a telescopic scaffold, and relates to the field of scaffolds. The telescopic scaffold comprises a connecting frame and a fixing mechanism, wherein inner threaded grooves are formed in the inner sides of the connecting frame, outer sleeve mechanisms are in threaded connection with the inner sides of the connecting frame, and inner sleeve mechanisms are connected to the innersides of the outer sleeve mechanisms in a clamped mode. According to the telescopic scaffold, four outer sleeves are in threaded connection with the interior of the connecting frame, gear shaping plates retreat from limiting grooves to the interiors of through grooves by rotating extending rods, supporting sleeves can be located below the outer sleeves by pressing the supporting sleeves downwards,after the extending rods are pulled outwards by a specified length, the extending rods are rotated reversely to enable the gear shaping plates to be inserted into the limiting grooves in the outer sides again, then clamping i
