Sleeve device with protection mechanism for underground power construction

The utility model discloses a casing pipe device with a protection mechanism for underground power construction, and relates to the technical field of power construction, a first casing pipe is hinged to one side of a fixing plate, a second casing pipe is hinged to one side, away from the first casing pipe, of the fixing plate, a worker can place a cable on the fixing plate firstly, then the first casing pipe and the second casing pipe are rotated, and then the cable can be fixed. When the first sleeve and the second sleeve are attached, the distance between the first sleeve and the second sleeve is adjusted in a self-adaptive mode through the buffer springs, the clamping plates can abut against the surface of the cable for limiting, the cable is prevented from shaking, and the service life of the cable is prolonged. And meanwhile, the buffering and damping effects of the cable can be improved, and when the cable needs to be disassembled, only the clamping plate needs to be pressed down to separate the first
