[0027] The two extrusion rods 3 are pressed to make the two limit protrusions 4 move relative to each other, so that the two limit protrusions 4 slide on the surface of the positioning shaft 10 and squeeze the return spring 11, so that the two limit protrusions 4 shrink into the interior of the first sliding block 2, and then pull the first sliding block 2 to disengage the first sliding block 2 from the interior of the limit groove 6. When the first sliding block 2 needs to be installed into the interior of the limit groove 6, the first sliding block 2 is inserted into the interior of the limit groove 6, and then the two extrusion rods 3 are no longer pressed, so that the two limit protrusions 4 are reset by the elastic force of the return spring 11, and then the two limit protrusions 4 enter the interior of the limit groove 6, completing the installation of the first sliding block 2, making it easy to connect the first sliding block 2 to the keel 1, and thus facilitating the later installation, preventing the need to install the first sliding block 2 into the interior of the keel 1 from one side of the keel 1 in the later stage, thereby improving the convenience of device installation.

[0029] When the two limiting protrusions 4 move back to back, the two fixing protrusions 9 will be inserted into the fixing holes 5 on both sides, thereby fixing the first sliding block 2. Since a plurality of fixing holes 5 are provided inside the limiting groove 6, it is convenient to adjust the position of the first sliding block 2, thereby facilitating the installation and connection of the horizontal and vertical keels.

[0030] A fixing ring 16 is slidably sleeved on the surface of the rotating shaft 13, and a convex tooth 17 is fixedly installed inside the fixing ring 16. A groove 18 is opened at the lower end of the rotating shaft 13, and the convex tooth 17 is slidably connected inside the groove 18. Two guide rods 14 are fixedly installed inside the first sliding block 2, and the two guide rods 14 are both slidably connected to the inside of the fixing ring 16. Springs 15 are movably sleeved on the two guide rods 14, and the upper ends of the two springs 15 are fixedly connected to the bottom of the fixing ring 16. The lower ends of the two springs 15 are respectively fixedly connected to the two guide rods 14. A fixed extrusion block 19 is fixedly installed on the surface of the fixing ring 16, and the shape of the upper end of the fixed extrusion block 19 is inclined.

[0032] Working principle:

[0033] The two extrusion rods 3 are pressed to make the two limit protrusions 4 move relative to each other, so that the two limit protrusions 4 slide on the surface of the positioning shaft 10 and squeeze the return spring 11, so that the two limit protrusions 4 shrink into the interior of the first sliding block 2, and then pull the first sliding block 2 to make the first sliding block 2 disengage from the interior of the limit groove 6. When the first sliding block 2 needs to be installed in the interior of the limit groove 6, the first sliding block 2 is inserted into the interior of the limit groove 6, and then the two extrusion rods 3 are no longer pressed, so that the two limit protrusions 4 are reset by the elastic force of the return spring 11, and then the two limit protrusions 4 enter the interior of the limit groove 6 to complete the installation of the first sliding block 2. When the two limit protrusions 4 move back to back, the two fixing protrusions 9 will be inserted into the interior of the fixing holes 5 on both sides, thereby fixing the first sliding block 2. Since a plurality of fixing holes 5 are provided inside the limit groove 6, it is convenient to adjust the position of the first sliding block 2.

[0034] When the limiting protrusion 4 moves, the squeezing plate 12 will move, and the roller 7 will squeeze the inclined surface of the fixed squeezing block 19, so that the fixed squeezing block 19 will slide downward on the surface of the rotating shaft 13 and the two guide rods 14 and squeeze the two springs 15, so that the convex teeth 17 will be disengaged from the grooves 18, and the second sliding block 8 will be rotated to drive the rotating shaft 13 to rotate. After adjusting the angle between the second sliding block 8 and the first sliding block 2, the squeezing rod 3 is no longer pressed to reset the limiting protrusion 4, and the fixing ring 16 is reset by the elastic force of the two springs 15, so that the convex teeth 17 are stuck in different grooves 18, so as to fix the rotation angle of the rotating shaft 13.
