[0027] Reference Figures 1 to 4 When the rear connector 3 is in use, the rear positioning part 12 is inserted into the rear positioning groove 31, and the rear spring 36 is in an open state, pushing the rear connector 3 upward. Since the height of the rear main gear mounting groove 33 is greater than the height of the rear main gear 8, the rear connector 3 can be pulled down. When the rear connector 3 is pulled down, the rear spring 36 is compressed, and the rear positioning part 12 disengages from the rear positioning groove 31. At this time, the rear connector 3 can rotate. After the rear connector 3 rotates 90°, it is released, and under the elastic force of the rear spring 36, the rear connector 3 automatically resets, and the rear positioning part 12 re-inserts into the rear positioning groove 31. When the rear connector 3 rotates, the two rear driven gears 91 can rotate synchronously and mesh with the rear main gear 8. At the same time, the meshing of the two rear driven gears 91 with the rear main gear 8 can ensure that the two rear shoe wheel connectors 9 are well fixed relative to the rear connector 3, ensuring that the orientation of the rear shoe wheel 5 will not tilt.

When the front positioning part 11 is inserted into the front positioning groove 21, the two front limiting parts 15 are located in front limiting grooves 28 on different sides. When the front connector 2 is rotated 90° and the front positioning part 11 is inserted into the front positioning groove 21, the two front limiting parts 15 are located in another front limiting groove 28 on different sides. The fact that the two front limiting parts 15 are located in front limiting grooves 28 on different sides can further prevent the front connector 2 from rotating. When the rear positioning part 12 is inserted into the rear positioning groove 31, the two rear limiting parts 16 are located in the rear limiting grooves 38 on different sides. When the rear connector 3 rotates 90° and the rear positioning part 12 is inserted into the rear positioning groove 31, the two rear limiting parts 16 are located in the other rear limiting grooves 38 on different sides. The fact that the two rear limiting parts 16 are located in the rear limiting grooves 38 on different sides can further prevent the rear connector 3 from rotating.

[0029] Reference Figure 1 and Figure 4 The bottom of the sole 1 is divided into a front mounting area 17 and a rear mounting area 18. The front connector 2 and the rear connector 3 are located in the front mounting area 17 and the rear mounting area 18, respectively.

[0030] The design principle of this utility model is as follows: (Refer to...) Figure 1 When the front connecting member 2 and the rear connecting member 3 are aligned, the roller skates can be used as inline skates. (Refer to...) Figure 5 When the rear connector 3 is pulled down and rotated 90°, the rear connector 3 and the front connector 2 become perpendicular, at which point the roller skate can be used as a double-row roller skate. (Refer to...) Figure 6 When both the rear connector 3 and the front connector 2 are pulled down and rotated 90°, the rear connector 3 and the front connector 2 become parallel, and the inline skates can then be used as another type of double-row inline skates. The above three different wheel arrangements are suitable for users at different stages. For example, the two types of double-row inline skates are more suitable for beginners, while inline skates are more suitable for advanced training and experienced skaters.

[0031] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
