When the driving assembly 13 drives the inner ring 14 to rotate, the connecting sections 1511 of the blades 151 rotate on the base 11, and slide on the inner ring 14, so that the size of the variable central hole 150 surrounded by the arc-shaped sections 1512 of the plurality of blades 151 is adaptively changed. Specifically, when the driving assembly 13 drives the inner ring 14 to rotate counterclockwise, the variable center hole 150 gradually becomes larger and can be adjusted to the maximum state, as shown in fig. 8; as the drive assembly 13 drives the inner race 14 clockwise, the variable center bore 150 is tapered and may be adjusted to a minimum configuration, as shown in fig. 9.

Specifically, as shown in fig. 5, a plurality of strip-shaped sliding grooves 141 for sliding a connecting section 1511 are formed on the inner ring 14, and a sliding column 1513 embedded in the strip-shaped sliding grooves 141 is disposed at a lower end of the connecting section 1511, as shown in fig. 7.
