Description

Technical field [0001] The invention relates to a tube expander which prevents deformation of clamped pipes. Background technique [0002] Pipe expanders are used in many aspects, such as pipe splicing and pipe welding, but the existing pipe expanders mostly clamp the pipes with fixed and coordinated fixtures and then work. There are two disadvantages in this method. One is fixed. There are height limitations in the clamping of pipes with clamps, and it is difficult to clamp the pipes at different heights. Second, when the fixed clamps are clamping the pipes, it is easy to cause damage to the pipes due to the small contact area of ​​the pipes. [0003] Therefore, the existing technology needs to be further improved. Summary of the invention [0004] In order to overcome the shortcomings of the background technology, a tube expander which prevents the deformation of the clamped pipe is provided. [0005] Resolve the background technology deficiency from the following technical soluti...
