[0021] Example: See Figures 1 to 2This embodiment provides a fishing umbrella support rod direction adjustable robotic arm structure, which includes a main body 1, a first rod 2 and a second rod 3 located at both ends of the main body 1 and movably connected to the main body 1; wherein, the main body 1 includes two opposite and staggered rotary locking joints 4, the front ends of the first rod 2 and the second rod 3 are movably connected to the rotary locking joints 4 through a rotating shaft 5, the front parts of the first rod 2 and the second rod 3 are respectively provided with a first movable block 6 and a second movable block 7 that cooperate with the rotary locking joints 4, the first movable block 6 and the second movable block 7 that cooperate with the rotary locking joints 4 are respectively provided with a first arc-shaped groove 8 and a second arc-shaped groove 9, the first arc-shaped groove 8 and the second arc-shaped groove 9 are provided with protruding teeth 10, and the surface of the rotary locking joints 4 is provided with rotating locking teeth 11 that cooperate with the protruding teeth 10.
[0022] The first rod body 2 and the second rod body 3 are respectively provided with a first anti-slip ring 12 and a second anti-slip ring 13, and the first anti-slip ring 12 and the second anti-slip ring 13 are respectively threadedly connected to the first rod body 2 and the second rod body 3.
[0023] The first movable block 6 is located at the front end of the first anti-slip ring 12, and the second movable block 7 is located at the front end of the second anti-slip ring 13. The first movable block 6 and the second movable block 7 are respectively rotatable relative to the first anti-slip ring 12 and the second anti-slip ring 13.
[0024] The first movable block 6 and the second movable block 7 are each provided with a connector at their mating ends with the first anti-slip ring 12 and the second anti-slip ring 13, and the first anti-slip ring 12 and the second anti-slip ring 13 are fitted onto the connector.
[0025] The first rod 2 and the second rod 3 are respectively provided with a first column 14 and a second column 15 at their front ends. A first shaft hole 16 is provided at the front end of the first column 14 and the second column 15, and a second shaft hole 17 is provided on the rotary snap connector 4.
[0026] The first movable block 6 and the second movable block 7 are respectively provided with a first spring 18 and a second spring 19 at their rear ends.

[0031] The working principle of this utility model is as follows:
[0032] By rotating the first and second anti-slip rings, they move up and down relative to the first and second rods. When the first anti-slip ring moves away from the first movable block, the first movable block is only restricted by the first spring. When the first rod is rotated along the opening of the column's rotating cavity, the protruding teeth and rotating locking teeth misalign and push the first movable block, thus achieving rotation. After being pushed by the first spring, the first movable block quickly returns to its original position. After adjustment, rotating the first anti-slip ring towards the first movable block fixes it, achieving rapid multi-angle gear adjustment. The second anti-slip ring and second movable block are linked in the same way as the first anti-slip ring and first movable block.
[0033] However, the above description is only a preferred embodiment of the present utility model and is not intended to limit the patent scope of the present utility model. Therefore, all other embodiments described in the present utility model and the equivalent changes made thereto are included within the protection scope of the present utility model.
