Lifting type periscope maintenance equipment in well

The utility model provides in-well lifting type periscope maintenance equipment, which relates to the technical field of periscope maintenance equipment, and comprises a base plate, an outer chuck is arranged above the base plate, sliding grooves are formed in the top of the outer chuck in a circumferential array mode, rotating holes are formed in the side face of the outer chuck in a circumferential array mode, and an inner chuck is rotatably connected to the inner wall of the outer chuck. The problem that pipeline accidents occur frequently is solved by installing a stepped clamp, in order to find pipeline hidden dangers in time, related units are provided with underground lifting periscopes, purchasing conditions of the units are different, the periscopes are large in model difference, part of the periscopes adopt mechanical refraction periscopes, and the other part of the periscopes adopt electronic periscopes. The pipe diameter of a mechanical refraction periscope is far larger than that of an electronic
