Quick earth auger for cable construction

The invention discloses a quick earth auger for cable construction. The quick earth auger comprises chassis connecting rods arranged symmetrically front and back, and a device box body is fixedly installed on the chassis connecting rods; the device box body is internally provided with a first gear cavity, and a gear shaft is internally provided with a drilling shaft through a spline; the bottom ofthe drilling shaft is provided with a drill bit for drilling; and a drilling motor is started, and a gear is driven by the drilling motor to rotate, and the gear shaft is rotated for driving the drilling shaft and the drill bit to rotate for drilling a hole in soil. According to the quick earth auger, a cable pit required for cables can be dug quickly, and a drilling piece can be regulated into an oblique state; a small pit formed properly is expanded, and repeated drilling operations are not required; the drilling shaft is portable, and soil upon completion of drilling can be dug up in one time, and is not piled tog
