Abstract
A pipe expanding device includes: a clamping assembly including a pipe expanding end, an opposite connecting end, and a receiving space in communication with the pipe expanding end and the connecting end; a pipe expanding assembly movably disposed in the receiving space; a connecting member disposed at the connecting end; and an elastic member disposed in the receiving space and located between the pipe expanding assembly and the connecting member to push the pipe expanding assembly back toward the connecting end after the pipe expanding assembly is moved toward the pipe expanding end. The elastic member is hidden in the clamping assembly and capable of automatically pushing the pipe expanding assembly back to its original position. Therefore, the motion of the pipe expanding assembly won't be affected by the displacement of the pipe expanding tool, and the pipe expanding assembling therefore won't get bent or fall off.
