Digital hygrothermograph

The utility model relates to the technical field of digital hygrothermometers, in particular to a digital hygrothermometer, which comprises a digital hygrothermometer and a round block, two sides of the digital hygrothermometer are respectively and fixedly connected with the round block, the top end of the digital hygrothermometer is fixedly connected with a support block, the right side of the digital hygrothermometer is rotatably connected with a support rod, and the support rod is fixedly connected with the round block. The inner wall of the supporting rod is slidably connected with a sliding rod, and the top of the sliding rod is fixedly connected with a screw. A user pulls a pressing block rightwards, the pressing block does not abut against a plurality of spherical blocks, then a rotating baffle is pulled, the baffle rotates along a round block through a rotating rod, the displayer is exposed for use, when the displayer is not used, the user pulls the pressing block, meanwhile, the rotating baffle is re
