In some embodiments of the present disclosure, as illustrated in Fig. 1, Fig. 2 and Fig. 8, the yo-yo with the functional accessory 4 convenient to detach includes a limiting member 3, and the limiting member 3 is movable between a first position a and a second position b. When 3 is at the first position a, the first mounting portion and the second mounting portion are fitted with each other. Thus, the installation and detachment of the functional accessory 4 can be realized by rotating the functional accessory 4 to enable a movement of the functional accessory 4 between the first position a and the second position b.
In some embodiments of the present disclosure, as illustrated in Fig. 1, Fig. 2 and Fig. 8, a sliding rail 21 is defined in the base assembly, the first position a and the second position b are located in the sliding rail 21, and the sliding rail 21 is provided with an inner mounting notch 23 and an outer mounting notch 22 opposite to the inner mounting notch 23. A part of the limiting member 3 is located in the outer mounting notch 22. An outer end of the limiting member 3 has a poking portion 31 and the poking portion 31 extends out of the outer mounting notch 22. Thus, the poking of the limiting member 3 is facilitated, the movement of the limiting member 3 between the first position a and the second position b can be realized by poking the poking portion 31. An inner end of the limiting member 3 is configured as the first mounting portion. When the limiting member 3 is in the first position a, the first mounting portion is located in the inner mounting notch 23. When the outer end of the limiting member 3 is poked, the first mounting portion can drive the second mounting portion to move. When the limiting member 3 is poked to move from the first position a to the second position b, the second mounting portion can be deviated from the inner mounting notch 23.
During the installation of the functional accessory 4, the outer end of the limiting member 3 is poked to be located at the first position a, so that the second mounting portion of the functional accessory 4 is fitted with the first mounting portion, and then the outer end of the limiting member 3 is poked to move to the second position b, and during the movement of the limiting member 3 to the second position b, the first mounting portion drives the second mounting portion to be deviated from the inner mounting notch 23, in which case a displacement of the second mounting portion is limited and hence a displacement of the functional accessory 4 is limited, so that the installation of the functional accessory 4 is finished.

When the supporting member 2 is tightly attached to an inner wall surface of the mounting cavity 11 and the inner wall surface of the mounting cavity 11 is provided with the first step surfaces 13, the surface of the supporting member 2 facing the inner wall surface of the mounting cavity 11 is provided with a step surface fitted with the first step surfaces 13, so that cooperation degree of the inner wall surface of the mounting cavity 11 and the supporting member 2 can be improved and reliability of the overall structure can be enhanced. In addition, the limiting member 3 is arranged between two adjacent first step surfaces 13, and a moving track of the limiting member 3 is further limited by means of two adjacent first step surfaces 13, the operation reliability of the limiting member 3 can be improved, so that the operation reliability of the overall mechanism can be improved, hence the installation and detachment of the functional accessory 4 can be facilitated.
As illustrated in Fig. 4, Fig. 5, Fig. 34 and Fig. 35, the inner wall of the mounting cavity 11 is provided with a plurality of second step surfaces 14, the plurality of second step surfaces 14 is arranged spaced apart along the circumferential direction of the opening 12, the second step surfaces 14 are spaced apart from the first step surfaces 13, and the limiting member 3 is slidably arranged between two adjacent second step surfaces 14. Thus, cooperation goodness of the inner wall of the mounting cavity 11 and the supporting member 2 can be further improved and the moving track of the limiting member 3 is further limited, so that the operation reliability of the overall structure can be improved, and the installation and detachment of the functional accessory 4 can be facilitated.
For example, in the examples illustrated in Fig. 34 and Fig. 35, the inner wall of the mounting cavity 11 is provided with three first step surfaces 13 and three second step surfaces 14. The three first step surfaces 13 and three second step surfaces 14 are all arranged spaced apart along the circumferential direction of the opening 12, the first step surfaces 13 are arranged adjacent to the opening 12 with respect to the second step surfaces 14, and the limiting member 3 can be slidably arranged between two adjacent first step surfaces 13 and two adjacent second step surfaces 14. Thus, not only the cooperation degree of the inner wall surface of the mounting cavity 11 and the supporting member 2 can be improved so as to prevent the supporting member 2 from being separated from the mounting cavity 11, but also the moving track of the limiting member 3 can be limited, so that the operation reliability of the overall structure is improved and hence the installation and detachment of the functional accessory 4 is facilitated.
Certainly, the present disclosure is not limited to this, for example, in the examples illustrated in Fig. 4 and Fig. 5, the inner wall of the mounting cavity 11 is provided with the first step surface 13 and the second step surface 14. The first step surface 13 and the second step surface 14 both extend along the circumferential direction of the opening 12, and the first step surface 13 is arranged adjacent to the opening 12 with respect to the second step surface 14. The surface of the limiting member 3 opposite to the inner wall surface of the mounting cavity 11 is separately fitted with the first step surface 13 and the second step surface 14, the limiting member 3 is slidably arranged on the first step surface 13 and the second step surface 14, and the moving track of the limiting member 3 can be defined by the sliding rail 21.

The annular gasket 5 and the limiting member 3 are snap-fitted with each other, the annular gasket 5 is provided with a snapping groove 51, and the limiting member 3 is snap-fitted in the snapping groove 51. Thus, when the outer end of one of the limiting member 3 is poked, the limiting member 3 can drive the annular gasket 5 to rotate in the annular groove 15, and the annular gasket 5 can drive other limiting members 3 to rotate. That is, when the outer end of one of the limiting members 3, all of the limiting members 3 can move simultaneously, it doesn't need to poke the outer end of all of the limiting members 3, so that the installation and detachment of the functional accessory 4 is facilitated.
For example, in the examples illustrated in Fig. 34, Fig. 35 and Fig. 38, the annular groove 15 is formed in the mounting cavity 11, the annular gasket 5 is embedded in the annular groove 15, and the annular gasket 5 is slidable in the annular groove 15. The annular gasket 5 is provided with the snapping groove 51 matched with an outer contour of the limiting member 3 along the circumferential direction of the opening 12, and the limiting member 3 is snap-fitted in the snapping groove 51. When the outer end of one of the limiting members 3 is poked, the limiting member 3 can drive the annular gasket 5 in cooperation with the limiting member 3 to rotate, and the annular gasket 5 can drive other limiting members 3 in cooperation with the annular gasket 5 to move, so that the movement of all of the limiting member 3 can be realized by poking one of the limiting members 3 and it doesn't need to poke all of the limiting members 3, hence the installation and detachment of the functional accessory 4 is facilitated.

In some embodiments of the present disclosure, as illustrated in Fig. 2, Fig. 12 and Fig. 22, the first mounting portion is formed to be the limiting notch 32 and the second mounting portion is formed to be a mounting protrusion 42. Thus, the structures of the first mounting portion and the second mounting portion can be simplified. The supporting member 2 is provided with a mounting through hole 26 suitable for the mounting protrusion 42 to pass through. When the limiting member 3 is located at the first position a, the mounting through hole 26 is communicated with the limiting notch 32. Thus, during the installation of the functional accessory 4, it is convenient for the mounting protrusion 42 to pass through the mounting through hole 26 to be fitted with the limiting notch 32, and during the detachment of the functional accessory 4, it is convenient for the mounting protrusion 42 to extend out of the limiting notch 32.
As illustrated in Fig. 9, Fig. 10, Fig. 19, Fig. 20, Fig. 29, Fig. 30 and Fig. 35, a plurality of the limiting members 3 is provided and arranged spaced apart along the circumferential direction of the opening 12. Thus, the reliability of fixation between the base 1 and the functional accessory 4 can be improved, which can prevent the functional accessory 4 from falling off when the yo-yo is used. As illustrated in Fig. 9, Fig. 10, Fig. 19, Fig. 20, Fig. 29 and Fig. 30, a connecting rib 34 is provided between two adjacent limiting members 3, thus, when the outer end of one of the limiting members 3 is poked, the limiting member 3 can drive the connecting rib 34 to rotate and the connecting rib 34 can drive the other limiting members 3 to rotate. That is, when one of the limiting members 3 is poked, all of the limiting members 3 can move simultaneously, it doesn't need to poke all of the limiting members 3 one by one, so that the installation and detachment of the functional accessory 4 is facilitated.
In some embodiments of the present disclosure, three or four limiting members 3 are provided. Thus, not only the structure is simplified, but also the reliability of the installation of the functional accessory 4 can be improved. The plurality of limiting members 3 is distributed evenly along the circumferential direction of the opening 12, so as to simplify the structure further and enable the functional accessory 4 to be subjected to force more uniformly, so that the functional accessory 4 is enabled to be installed more securely.
For example, in the examples illustrated in Fig. 9, Fig. 10, Fig. 19, Fig. 20, Fig. 29 and Fig. 30, three limiting members 3 are provided and spaced apart evenly along the circumferential direction of the opening 12, the connecting rib 34 is disposed between every two adjacent limiting members 3 so as to connect the three limiting members 3 into one piece.

As illustrated in Fig. 12, the stopping cavity 24 is formed in the sliding rail 21 and communicated with the inner mounting notch 23. When the limiting member 3 is poked to move from the first position a to the second position b, the second mounting portion moves into the stopping cavity 24. A surface of the second mounting portion facing the outer side of the mounting cavity 11 is abutted against a surface of the stopping cavity 24 facing the inner side of the mounting cavity 11 so as to limit the displacement of the second mounting portion in the direction of the outer side of the mounting cavity 11, and hence prevent the functional accessory 4 from being separated from the base 1.
