The invention discloses a combined line inspection crutch, which comprises a main body pipe and a cylindrical base, wherein a cavity used for accommodating repair tools is arranged in the main body pipe; a handheld part is arranged at the upper part of the main body pipe; the cylindrical base is internally connected onto the bottom of the main body pipe through screw threads; an upper clamp hook and a lower clamp hook are arranged on the cylindrical base; the upper clamp hook is connected onto the cylindrical base in a sleeving way; the lower clamp hook is detachably connected onto the side wall of the cylindrical base; the hook head of the upper clamp hook is used for being clamped and connected with a clamp ring used for controlling an animal clamp to open and close; when the main body pipe downwards moves relative to the cylindrical base, the upper clamp hook approaches to the lower clamp hook, two semi-circular clamp rings of the animal clamp are in a loose state. When the combined line inspection crutch is used, and when the animal clamp does not need to be opened, the upper clamp hook and the lower clamp hook can be stored into the cavity in the main body pipe. At the moment, the combined line inspection crutch can be used as a crutch so that a user can conveniently walk in rugged environment. In addition, the maintenance tools can be accommodated into the cavity in the main body pipe, so that the trouble of respectively carrying the maintaining tools is avoided; in addition, the use function of the line inspection crutch is improved.
