Description

Technical Field

[0001] The utility model relates to the technical field of PU spring tube fixing, and specifically relates to a PU spring tube fixing mechanism. Background Technique

[0002] The PU spring tube has good ductility and flexibility. Therefore, when the PU tube leaves the factory, a hot air film sleeve is sleeved on its outside to improve the portability and storage convenience of the PU spring tube. Since the hot air film sleeve is a disposable item, when the hot air film sleeve is opened, the PU spring tube will become loose without the fixation of the hot air film sleeve. When the worker finishes using the PU spring tube and stores it, the PU spring tube is likely to be entangled with other objects, which leads to inconvenient storage and placement of the PU spring tube. In view of the above situation, technological innovation is carried out on the basis of the existing PU spring tube fixing mechanism. Content of the Utility Model
