When in use, rotate the adjusting handle 607. The adjusting handle 607 can drive the connecting rod 604 to rotate. There are two gears 605, both of which are fixedly connected to the connecting rod 604 coaxially. When the connecting rod 604 rotates, it can drive the gears 605 to rotate. Since the teeth of the gears 605 are meshed with the surface of the tooth block 603, the forward or reverse rotation of the gears 605 can drive the adjusting plate 602 to drive the leg support plate 5 to displace. The adjusting plate 602 slides along the mounting plate 601. When the leg support plate 5 extends a certain distance, the inclined surface of the first inclined block 10 first contacts the inclined surface of the second inclined block 12, and a preliminary positioning of the leg support plate 5 is performed, so that the leg support plate 5 cannot rotate, facilitating the experiencer to lie flat on the sofa to rest. When the leg support plate 5 needs to be rotated and supported, continue to rotate the adjusting handle 607. Since the inclined surfaces of the first inclined block 10 and the second inclined block 12 are in contact, the first inclined block 10 can squeeze the second inclined block 12 to contract. The leg support plate 5 is rotatably connected to the adjusting plate 602 through the connecting shaft 501. When the leg support plate 5 rotates, it drives the connecting shaft 501 to rotate. Through the cooperation of the arc block 502 and the elastic piece 16, the limiting effect of the rotation of the leg support plate 5 is increased. Therefore, the multi-gear sofa leg support mechanism has a simple and compact structure, can effectively realize the convenient storage and adjustment of the leg support plate 5, and increases the practicability of the sofa.
