One end of the locking rod 3 passes through and is installed in the slot 14 and is elastically movably connected to the slot 14 in a returnable manner, and the other end is selectively limited by a stepped surface with the button 2 to limit the axial movement of the locking rod 3. The tooth head 4 and the locking rod 3 are arranged opposite to each other, the tooth head 4 is rotatably connected to the mounting sleeve 1, and the tooth head 4 and the locking rod 3 cooperate to form a plug-in anti-rotation structure, so that the two can be selectively engaged.

[0036] One end of the pin shaft 5 is provided with an external thread, and the third pin shaft hole 53 is provided with an internal thread, and one end of the pin shaft 5 is threadedly connected to the third pin shaft hole 53.

[0037] The button 2 is sized to match the installation groove 11 and is embedded in the installation groove 11. The button 2 includes a pressing portion 21 and a stepped portion 22. The stepped portions 22 are symmetrically arranged on both sides of the lower side of the pressing portion 21, and there is a gap between the stepped portions 22 on both sides to accommodate the locking rod 3 to pass through. In this embodiment, the locking rod 3 passes through the stepped portions 22 of the button 2 and is inserted into the slot 14.

[0038] The lower end of the stepped portion 22 includes two steps extending forward. The steps include a first step 23 and a second step 24. The first step 23 is fixedly arranged at the lower end of the stepped portion 22, and the second step 24 is located below the first step 23 to form a stepped surface. When in the rotating state, the locking rod 3 abuts against the sides of the stepped portions 22 on both sides. When in the locking state, the locking rod 3 is located on the stepped surface between the first step 23 and the second step 24 and maintains a gap with the stepped portion 22. It should be noted that the abutting and limiting position of the locking rod 3 and the second step 24 is an inclined surface that fits each other to facilitate the reset of the button 2.

[0039] The installation sleeve 1 further includes a reset seat 12. The reset seat 12 is fixedly arranged on the side wall of the installation groove 11 and is located below the pressing portion 21. A counterbore 13 is provided on the upper side surface of the reset seat 12, and a reset spring (not shown in the figure) is arranged in the counterbore 13. One end of the reset spring abuts against the lower side surface of the pressing portion 21, and the other end is connected to the inner wall of the counterbore 13 to support the button 2. The side surface of the stepped portion 22 abuts against the side surface of the reset seat 12.

[0040] The slot 14 is sized to match the locking rod 3. A long spring (not shown in the figure) is installed in the slot 14. One end of the long spring is connected to the locking rod 3, and the other end is connected to the bottom surface of the slot 14 to drive the axial movement of the locking rod 3. The locking rod 3 includes a locking portion and an adjusting rod 32. A tooth groove 31 is provided on one side surface of the locking portion, and the other side surface is connected to the adjusting rod 32. The adjusting rod 32 is inserted into the slot 14, and the locking portion is located outside the slot 14.

[0041] A gear 41 is provided on the tooth head 4, and the gear 41 can be meshed and matched with the tooth groove 31. In the locking state, part of the gear 41 is meshed with the tooth groove 31.

[0042] Working principle:

[0043] The installation sleeve 1 is connected to the ground rod below, and the tooth head 4 is connected to the umbrella rod above. When the angle of the fishing umbrella needs to be adjusted, press the button 2, and the second stepped surface in contact with the locking portion moves until the locking rod 3 and the button 2 lose the limit. The locking rod 3 can axially move in the slot 14. At this time, rotate the tooth head 4 to the angle to be adjusted. During the rotation, the locking rod 3 can make an adaptive movement under the action of the long spring so that the tooth groove 31 and the gear 41 remain engaged. After the adjustment is completed, release the button 2; under the action of the return spring, the button 2 moves outward to reset, and at the same time, the locking rod 3 and the second step 24 resume the stepped limit again, and the steering knuckle is in the locked state.

[0044] Specific Embodiment 2: Please refer to Figures 9 - 10 A push-type steering knuckle for a fishing umbrella, which is the same as Specific Embodiment 1 and will not be described herein again. The difference lies in that: a multi-level stepped surface limit is provided between the locking rod 3 and the button 2.
