[0042] The measuring device of the above structure is provided with a connecting component 3 on the measuring piece 1. The connecting component 3 specifically includes a connecting piece 31. The connecting piece 31 is a connecting plate in this embodiment. The connecting piece 31 is specifically rotatably connected to the measuring piece 1, and the connecting piece 31 has a connecting surface 311. When the abutting surface 11 of the measuring piece 1 abuts the bottom surface of the pipe segment 4, the connecting piece 31 can rotate relative to the measuring piece 1 under the action of external force, so that the connecting surface 311 of the connecting piece 31 can abut the side of the pipe segment 4, and when the connecting surface 311 abuts the side of the pipe segment 4, the connecting surface 311, the alignment surface 13 and the side of the pipe segment are coplanar.

After the measurement is completed, the support piece 32 can rotate relative to the measuring piece 1 under the action of external force and correspond to the yield portion on the connecting piece 31, so that when the connecting piece 31 is separated from the side of the pipe segment 4 under the action of gravity, each support piece 32 can enter the yield portion, thereby helping to improve the overall appearance of the measuring device.
