The invention discloses a portable concrete drilling machine that includes a mounting plate, a sliding rail, a direction-adjusting sliding device, a detachable motor, a water injection pump, a water valve, and a drilling cylinder. After a hole is drilled, an advance rack is reset. Then, a support helper ejects an extension arm. According to a required drilling direction, a winch at a connection poisition is deflected to turn the extension arm to the corresponding direction. After the direction is determined, rotary hinges are ejected to fix ladder piece between every two rotary hinges so as tosupport the extension arm, thereby ensuring the stability during a drilling process, allowing the drilling machine to drill the surroundings without moving the mounting plate, achieving good flexibility and saving time. When the portable concrete drilling machine not in use is required to be transported, a left fitting pile can be separated from a right fitting pile by removing a staple head, sothat left and right bracke
