When the detection square shaft 4422 collides with the cam square table, the fixing spring 4427 contracts. The friction motor 4433 rotates slowly until the scalloped disk positioning tabs of the car seat adjuster snap into the positioning slots 44321. The friction motor 4433 continues to rotate until the direction of the detection square shaft 4422 is consistent with that of the square hole, and the detection square shaft 4422 is inserted into the square hole. At this time, the output shaft of the square shaft cylinder 4425 is extended, and the detection square shaft 4422 is inserted into the square hole. At this time, the torque motor 4423 is started, the detection square shaft 4422 applies unlocking force to the automobile seat angle adjuster, and the torque sensor 4424 detects the torque of the torsion spring of the automobile seat angle adjuster.
