This utility model discloses an angle-adjustable steering knuckle, relating to the field of umbrella accessory technology. It includes a stop clip for connecting the umbrella pole, a base for connecting the ground pole, a toothed head, and a drive component. The stop clip is rotatably connected to the upper part of the base. A vertically formed through-cavity is provided inside the base, and the toothed head is slidably disposed within the cavity to prevent rotation. The drive component is movably sleeved on the outside of the base and is connected to the toothed head via a transmission connection. It has the ability to drive the toothed head to reciprocate and lock in a lifting and lowering motion, so that the toothed head can be limited to contact or separate from the stop clip. In the locked state, the toothed head is limited to contact the stop clip to restrict the rotation of the stop clip relative to the base. In the rotating state, the toothed head is separated from the stop clip, allowing the stop clip to rotate freely. The drive component structure of this utility model features high locking stability, providing a more reliable locking force for the umbrella steering knuckle.
