The working process of the utility model is as follows:
the angle adjusters are symmetrically arranged on two sides of the seat, and driving shafts 5 of the angle adjusters on the two sides are connected through a synchronizing rod. When locking is to be performed, the synchronous rod drives the driving shaft 5 to rotate clockwise, the cam positioning block 5-3 drives the cam 3-1 to rotate clockwise, the contact point of the first cam gradually-changing surface 3-161 and the first gear block gradually-changing surface 3-221 and the contact point of the second cam gradually-changing surface 3-162 and the second gear block gradually-changing surface 3-222 are expanded outwards, the gear block 3-2 moves outwards along the gear block sliding groove 1-8 in the radial direction until the outer gear part 3-21 is meshed with the inner gear ring of the inner periphery of the movable disc 2, and the structure is shown in fig. 10.

When the locking is completed, the synchronous rod can generate certain angle error due to uneven stress in the rotating process. At this time, the gap 6 between the cam positioning block 5-3 and the gear positioning slot 3-12 is located on the right side of the cam positioning block 5-3, when unlocking is needed (anticlockwise rotation), the synchronous rod drives the driving wheel 5 to anticlockwise rotate, the driving wheel 5 overcomes the elastic force of the driving shaft pre-tightening coil spring to anticlockwise rotate until the gap 6 between the cam positioning block 5-3 and the gear positioning slot 3-12 is located on the left side of the cam positioning block 5-3, and as shown in fig. 11, the driving wheel 5 starts to drive the cam 3-1 to anticlockwise rotate to start unlocking. In the process, the angle error of the synchronizing rod is released (the elastic force of the pre-tightening coil spring of the driving shaft is far smaller than the force of the synchronizing rod causing the angle error in the locking process), and the unlocking synchronization of the two sides is ensured.
