The first annular rib 2a and the second annular rib 2b may define a sliding rail 21 with an inner wall of the mounting cavity 11, and a mounting outer notch 22 is provided at a position of the sliding rail 21 near the first annular rib 2a, and the sliding rail 21 is adjacent to the first The inner annular gap 23 and the stop cavity 24 are provided at the position of the second annular rib 2b. Thereby, the structure and the processing process of the support member 2 can be simplified, thereby saving the production cycle and reducing the production cost.

In some embodiments of the present invention, as shown in FIGS. 2, 12, and 22, the first mounting portion is formed as a limiting notch 32, and the second mounting portion is formed as a mounting boss 42, thereby simplifying the first The structure of the mounting portion and the second mounting portion. The supporting member 2 is provided with a mounting through hole 26 adapted to pass through the mounting protrusion 42. When the limiting member 3 is at the first position a, the mounting through hole 26 penetrates the limiting notch 32. Therefore, when the functional component 4 is mounted, the mounting protrusion 42 is easily engaged with the limiting notch 32 through the mounting through hole 26, and when the functional component 4 is detached, the mounting protrusion 42 is easily protruded from the limiting notch 32.

As shown in FIGS. 9 , 10 , 19 , 20 , 29 , 30 , and 35 , the stoppers 3 are plural and are spaced apart in the circumferential direction of the open opening 12 . Thereby, the reliability of fixing the base 1 and the functional component 4 can be improved, and the functional component 4 can be prevented from falling off during use of the yo-yo. A connecting rib 34 is disposed between the two limiting members 3 adjacent to each other as shown in FIG. 9, FIG. 10, FIG. 19, FIG. 20, FIG. 29 and FIG. 30, whereby when the outer end of one of the limiting members 3 is toggled The limiting member 3 can drive the connecting rib 34 to rotate, and the connecting rib 34 can drive the remaining limiting member 3 to rotate. That is to say, when one of the limiting members 3 is moved, all the limiting members 3 can be moved at the same time, and the limited position 3 is not required to be moved one by one, thereby facilitating the installation and disassembly of the functional fitting 4.

In some embodiments of the present invention, the limiting members 3 are three or four, whereby not only the structure can be simplified, but also the reliability of the installation of the functional fittings 4 can be improved. The plurality of stoppers 3 are evenly distributed along the circumferential direction of the open opening 12, whereby the structure can be further simplified, and the force applied to the functional fitting 4 can be made more uniform, thereby making the functional fitting 4 more securely mounted.

For example, in the examples shown in FIGS. 9 , 10 , 19 , 20 , 29 , and 30 , the limiting members 3 are three and the three limiting members 3 extend the circumferential direction of the opening 12 uniformly. The spacing member is provided with a connecting rib 34 between each adjacent two limiting members 3 to connect the three limiting members 3 into one body. Therefore, when one of the limiting members 3 is pushed, the limiting member 3 can drive the connecting ribs 34 to rotate, and the connecting ribs 34 can drive the remaining limiting members 3 to rotate. That is to say, when one of the limiting members 3 is moved, all the limiting members 3 can be moved at the same time, and the limited position 3 is not required to be moved one by one, thereby facilitating the installation and disassembly of the functional fitting 4. Of course, the limiting member 3 and the connecting rib 34 can be integrally formed. It should be noted that, as shown in FIG. 4, FIG. 14, and FIG. 24, the inner bottom wall of the mounting cavity 11 is provided with an annular groove 15 through which the connecting ribs 34 can move.
