[0024] One end of the rotating bolt 5 is threadedly connected to the second connecting block 8 in a through-shape, one end of the second connecting block 8 is fixedly connected to the second frame body 9, one side of the second frame body 9 is fixedly connected to the outer frame 10, the outer frame 10 is arranged in two semicircles, a sliding rod 15 is slidably connected between the outer frames 10, one side of the outer frame 10 is symmetrically fixedly connected to a connecting buckle 11, the bottom of the connecting buckle 11 is fixedly connected to a sliding plate 12, one end of the sliding plate 12 is slidably connected to a sliding sleeve 13 in a through-shape, and one end of the sliding sleeve 13 is slidably connected to an inner shell 14;
[0025] The inner wall of the outer frame 10 is fixedly connected with a spiral strip 17, the number of sliding sleeves 13 is two, the number of sliding plates 12 corresponds to the number of sliding sleeves 13, the sliding sleeves 13 are arranged in an L shape, one end of the rotating bolt 5 is threadedly connected with a fixing nut 6, the number of fixing nuts 6 is two, the number of rotating bolts 5 corresponds to the number of fixing nuts 6, and the top of the rotating bolt 5 is fixedly connected with a rotating cover 7.
[0026] In the first embodiment, the coreless rod to be inspected is put on the inner shell 14, and then the first frame 3 and the second frame 9 are tightened, and the outer diameter of the coreless rod is detected by using the moving distance of the rotating bolt 5. In this way, coreless rods of various sizes can be inspected, and the coreless rod can also be fixed during the inspection, which can ensure that the coreless rod will not be displaced during the inspection, thereby ensuring the accuracy of the inspection data and improving the inspection efficiency.
[0027] The outer wall of the inner shell 14 is fixedly connected with grinding rings 18 in sequence, and the number of grinding rings 18 is eight to ten. A connecting disk 19 is slidably connected to one side of the inner shell 14 in a penetrating manner, and a motor 16 is fixedly connected to the center position of one side of the connecting disk 19.

When the grinding ring 18 rotates, it can drive the friction strip 20 to rotate. When the grinding ring 18 rotates, the centrifugal force is used to concentrate the coolant 23 on one side of the friction strip 20, and at the same time, it can also drive the support rod 21 to move.
