[0030] The main unit 100 includes a detector 101, and a connecting plate 102 is provided on one side of the detector 101;

[0031] The support unit 200 includes a support rod 201, one end of which is fixedly connected to the connecting plate 102, and the other end of the support rod 201 is fixedly connected to a rotating shaft, and the surface of the rotating shaft is rotatably connected to a rotating seat 202 through a bearing, and the rotating seat 202 is fixedly connected to two groups of fixed plates 204 on the side away from the support rod 201, and the interior of the fixed plate 204 is rotatably connected to a threaded tube 205 through a bearing, both ends of the threaded tube 205 are provided with thread grooves, and the thread grooves are rotatably connected to threaded rods 206, and the ends of the two groups of threaded rods 206 that are away from each other are fixedly connected to a pressure rod 207.
