Glossy detector for high-temperature-boiling-resistant coating for vacuum cup

The utility model relates to the technical field of glossiness detectors, in particular to a glossiness detector of a high-temperature boiling resistant coating for a vacuum cup, the glossiness detector comprises a workbench and a glossiness detector body, the upper end of the workbench is fixedly connected with a first bearing seat, the interior of the first bearing seat is fixedly connected with a sliding rod, and the interior of a second bearing seat is rotatably connected with a rotating rod; connecting rods are fixedly connected to the circumferential surface of the rotating rod, the connecting rods are symmetrically distributed at the left and right ends of the fixing frame, and a protective cover is fixedly connected to the ends, close to each other, of the two connecting rods and used for covering the bottom end of the gloss detector body; under the action of the lifting mechanism, the gloss detector body can be driven to stably move up and down along the sliding strip, so that the high-temperature-re
