Claim 15:
16. A method for using a tensioning mechanism,
the tensioning mechanism comprising:
a housing, wherein the housing comprises an accommodation cavity, and the housing is configured to be sleeved with a to-be-tensioned material;
a tensioning assembly, wherein the tensioning assembly is mounted in the accommodation cavity;
a driving assembly, wherein the driving assembly is mounted on the housing, the driving assembly is configured to drive the tensioning assembly to move against the housing, so that at least a part of the tensioning assembly protrudes from or retracts into the housing, and the driving assembly comprises a handle mounted on an outer side of the housing and configured to manually drive the tensioning assembly to move against the housing;
a bearing, wherein the bearing is mounted on the housing through a mounting base, and the bearing at least partly protrudes out of the housing; and
a pressing piece;

the method comprising:
driving the handle to rotate against the housing, so that the pressing piece at least partly retracts into an interior of the accommodation cavity;
sleeving the housing with the material, the material being a roll-shaped material; and
driving the handle to rotate against the housing, so that at least a part of the pressing piece protrudes out of the housing and abuts on the material, to limit motion of the material against the tensioning mechanism.
