description The utility model discloses a single-cylinder plug-pin type telescopic arm and a hydraulic plug-pin interlocking device for the same. The interlocking device comprises an arm pin clamping groove moving under the action of an arm pin telescopic cylinder, cylinder pins moving under the action of a plunger pushed by hydraulic oil, and hydraulic cylinder pin locks located at the tail ends of the left cylinder pin and the right cylinder pin on the lower side, wherein moving routes of the cylinder pin locks are intersected with moving routes of the cylinder pins in a same plane, and cylinder pin lock telescopic cylinders and arm pin telescopic cylinders are communicated via pipelines, so as to realize the synchronous movement of pistons; when the arm pin clamping groove moves to an unlocking position, the upper cylinder pin is locked by the arm pin clamping groove, and the lower cylinder pin is locked by the hydraulic cylinder pin locks; when the cylinder pins move to the unlocking position, the upper cylinder pin
