[0077] The mounting platform 7 is changed from a horizontal use state to a vertical storage state, driving the unlocking rod 941 to move so that the elastic hook 92 no longer abuts against the end surface of the locking block 93 toward the bottom wall of the groove 74, and then driving the operating plate 91 to descend, and then driving the mounting platform 7 to rise, and driving the mounting platform 7 to rotate to the vertical storage state, and finally driving the mounting platform 7 to move toward the protective plate 6, so that the operating block 911 is inserted into the slot 75, so as to realize the storage of the mounting platform 7.
