[0028] The end of threaded rod 13 is provided with polygonal notch 16.

[0029] In the technical scheme, the collapse of the expansion and contraction winding drum refers to the deformation of the structure of the expansion and contraction winding drum under the action of external pressure or environmental factors, which causes the normal shape to be destroyed and the concave or flat state to appear. During transportation or storage, if the winding drum is subjected to the pressure or extrusion of other objects, the outer wall of the winding drum may be compressed and collapsed. In order to solve such problems, the specific operation is as follows: the opening assembly is installed between the first mounting block 2 and the second mounting block 3, then the first mounting block 2 and the second mounting block 3 are installed in the winding drum body 1 by using the fixing assembly, then the external tool is inserted into the polygonal notch 16, and then rotated to drive the threaded rod 13 to rotate. The limiting effect of the slide rod 15 on the extrusion block 14 enables the extrusion block 14 to move inside the winding drum body 1. The curved surface of the extrusion block 14 can open the deformed or concave part. The opening of the deformed or concave part by the opening assembly can effectively restore the original shape of the expansion and contraction winding drum, ensure its normal use, reduce the dysfunction caused by deformation, and the operation is simple and easy to operate.
