Only simple clamps are used and the operation is performed manually, resulting in low work efficiency, high failure rate, and high safety risks, which seriously affect work efficiency and safe production. If a pipe bending machine is used, the pipe bending machine is generally large in size and inconvenient to move. In the production of single-track switch products, it is often necessary to bend the wire tubes at multiple positions at any time. The existing pipe bending machines are not convenient enough. Therefore, the utility model proposes a portable pipe bending tool to solve the problems existing in the prior art. Summary of the Invention
