[0032] In this embodiment: when fixing the aluminum alloy profile, the fixing seat 702 is extended into the inner cavity of the aluminum alloy profile, and then the rotating sleeve 710 is rotated. The rotating sleeve 710 rotates to drive the gear ring 709 to rotate, and the gear ring 709 rotates to drive the spur gear 708 to rotate.
