The invention relates to bulb installing and detaching devices, particularly to a high bulb installing and detaching device. The high bulb installing and detaching device is formed by a probing rod and an elastic installing and detaching device which is fixed at the top of the probing rod; the elastic installing and detaching device comprises a base; four S-shaped grip fingers which are uniformly distributed and formed by guide cone sections, grip sections and restraint sections are arranged at the upper end of the base in a hinged mode, wherein the guide cone sections are arranged on the upper portions, the grip sections are arranged in the middle portions, and the restraint sections are arranged on the lower portions; the upper portions of the four grip fingers are bundled through a bundle spring; rubber linings are fixed on the grip sections of the grip fingers; the center of the upper end surface of the base is provided with a screw hole; an adjusting support which is in a curved surface shape and is arranged on the upper surface of the base is screwed into the screw hole through a screw arranged on the bottom surface of the adjusting support; the upper surface of the adjusting support is provided with rubber linings; the lower end of the base is fixed at the top end of the probing rod. According to the high bulb installing and detaching device, a high stool and a ladder are not required, installation and detachment are convenient, time and labor are saved, the use is safe, and the problems that users cannot install and detach high bulbs by standing on the ground through the existing devices and the time and the labor are wasted when the high bulbs are installed and detached through the high stool and the ladder are solved.
