This invention belongs to the field of laser measurement technology and discloses a tool for detecting the internal diameter, roundness, and straightness of a cylinder. It includes an equidistant detection arm assembly, with an axis correction arm assembly surrounding the equidistant detection arm assembly and supporting it on the cylinder's internal axis. Three sets of detection disk assemblies are located at one end of the equidistant detection arm assembly. The correction disks of this invention drive multiple support arms to perform synchronous outward extension movements via the auxiliary arm. Multiple traveling wheels at the top of the support arms abut against the inner wall of the cylinder, forming an axis correction structure. In this way, when the equidistant detection arm assembly is in use, its axis coincides with the cylinder's axis, facilitating the acquisition of detection data during subsequent detection of the cylinder's internal diameter, roundness, and straightness. The detection disk assembly of this invention is equipped with a self-rotation protection module, which enables the laser rangefinder to spin into the brush arm for self-rotation cleaning and protection.
