However, as the functions of steering wheel integration are increased, including instrument panel control, cruise control, voice call, etc., the reliability requirements for the steering springs are also increasing.

At present, the upper end of the clock spring is made into a boss form to be matched with a pipe column shaft of a steering pipe column, and the steering wheel is connected with the pipe column shaft in a spline form, so that the pipe column shaft can be driven to rotate when the steering wheel is rotated, and the pipe column shaft drives the upper end of the clock spring to rotate, so that the upper end of the clock spring and the steering wheel keep synchronous rotation. However, due to the fact that the traditional clock spring and the pipe column shaft synchronously rotate, the technical problem that the steering wheel is not centered easily occurs after the four-wheel positioning is adjusted or the transmission shaft is maintained is caused, and the clock spring does not have a steering return stop block, so that the steering lamp switch is reset and is poor in neutrality.
