The output end of the driving motor meshes with the annular gear 311 or the driven gear 33 through the gear to drive the swivel 31 to rotate on the cross beam 101 and the longitudinal beam 102, thereby driving multiple driven gears 33 to rotate synchronously, so as to realize the synchronous rotation of the screw 32 in the cross beam 101 and the longitudinal beam 102, thereby pushing the first sliding frame 23 and / or the second sliding frame 24 on the cross beam 101 and the longitudinal beam 102 to move the first hinged beam 21 and / or the second hinged beam 22 within the angle position between the cross beam 101 and the longitudinal beam 102, so that the longitudinal beam 102 rotates around the middle part of the cross beam 101 to adjust the angle between the cross beam 101 and the longitudinal beam 102, thereby realizing the adjustment of the area of ​​the lifting surface of the hanger 1.
