The invention provides a convenient-to-install device for overhauling and protecting an electrical
automation device. The convenient-to-install device comprises a rack, supporting rods, supporting legs, a
control switch, a supporting frame, a hanging ring, fixing nuts, adjusting screw rods, an adjusting
handle, an installing frame, installing holes, a movable rotating adjusting overhauling rod structure, a protecting
rope structure preventing the
device form falling during overhauling and a bendable moving adjusting overhauling illuminating lamp structure. According to the convenient-to-install device, by arranging the supporting frame, the fixing nuts, the adjusting screw rods, the adjusting
handle, the installing frame and the installing holes, the electrical
automation device can be rapidly installed and fixed, and the overhauling operation can be conveniently carried out; according to the size or model of the electrical
automation device, the adjusting
handle is rotated, and the adjusting screw rods are adjusted to act in the fixing nuts, so that the adjusting screw rods drive the installing frame to move through bearings, and the distance between the supporting frame and the installing frame can be changed; and through the installing holes, the electrical automation device can be fixed and installed thorough bolts so that overhauling can be conveniently carried out, and the operation is convenient.
