The main spring board (2), the supplementary spring board (4) and the supporting spring board (5) are arched in one orientation. The upper end of the supplementary spring board (4) is hinged on the bottom of the shoe rack (1), the lower end is hinged with the upper end of the supporting spring board (5), the lower end of which is hinged on the bottom palm (3). The activity bracket is attached to the location hole of the shoe rack (1) by adjustment screws (8) and adjustment nuts.
