[0060] Referring to Figures 7 to 9 The upper connecting piece 110 at the bottom of the shoe body 100 is used to cooperate with the lower connecting piece 500 at the top of the third upper pedal 410.

[0061] The child user can wear the shoe body 100 to connect with the second exercise assembly 300, or can wear the shoe body 100 to separate from the second exercise assembly 300.

[0062] When the shoe body 100 needs to be connected to the third exercise assembly 400, the connecting hole 120 at the bottom of the shoe body 100 is aligned with the lower connecting piece 500, and the shoe body 100 is rotated clockwise to make the three upper connecting portions 111 of the upper connecting piece 110 respectively align with the three lower avoiding grooves 512 of the lower connecting piece 500, and the three lower connecting portions 511 of the upper connecting piece 110 respectively align with the three upper avoiding grooves 112, as viewed from top to bottom; then the shoe body 100 is moved downward to the top surface of the third upper pedal 410 to make the three upper connecting portions 111 respectively inserted into the three lower avoiding grooves 512 and the three lower connecting portions 511 respectively inserted into the three upper avoiding grooves 112, so that the three lower connecting portions 511 are staggered with the three upper connecting portions 111 in the up-down direction, and the three lower connecting portions 511 are respectively moved to the notches of the three upper insertion grooves 113 and the three upper connecting portions 111 are respectively moved to the notches of the three lower insertion grooves 513; finally, the mounting cover 460, the third lower pedal 420 and the third upper pedal 410 are fixedly installed, and the shoe body 100 is counterclockwise rotated to make the three upper connecting portions 111 respectively inserted into the three lower insertion grooves 513 and the three lower connecting portions 511 respectively inserted into the three upper insertion grooves 113, until the three upper blocking portions 114 respectively abut against the three lower connecting portions 511 and the three lower blocking portions 514 respectively abut against the three upper connecting portions 111.

[0063] When the foot of the child user is worn with the shoe body 100 connected to the third exercise assembly 400, the child can twist the foot to drive the third upper pedal 410 to rotate, so that the third upper pedal 410 is rotated relative to the third lower pedal 420, thereby exercising the twisting action of the child's foot.

[0064] When the shoe body 100 needs to be separated from the third exercise assembly 400, the mounting cover 460, the third lower pedal 420 and the third upper pedal 410 are fixedly installed, and the shoe body 100 is clockwise rotated to make the three upper connecting portions 111 respectively slide out of the three lower insertion grooves 513 and the three lower connecting portions 511 respectively slide out of the three upper insertion grooves 113; then the shoe body 100 is moved upward to make the three upper connecting portions 111 respectively disengaged upward from the three lower avoiding grooves 512 and the three lower connecting portions 511 respectively disengaged from the three upper avoiding grooves 112, so that the shoe body 100 is separated from the third upper pedal 410.

[0065] In summary, the child can wear the shoe body 100 to be matched with the first exercise assembly 200, the second exercise assembly 300 or the third exercise assembly 400 at will, to realize various forms of leg exercise, avoid the foot of the child from sliding out of the exercise equipment, and the shoe body 100 can be conveniently switched between the multiple exercise equipment, thereby improving the enthusiasm of the child in using the leg exercise equipment.

[0066] The daily shoe body is combined with the exercise equipment, the shoe body and the exercise equipment are toyized, the lower limbs can be exercised, the children's hand operation ability is improved, and the interestingness of the exercise equipment is improved.

[0067] The above describes the embodiments of the application in detail in combination with the drawings, but the application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application.
