A first locking slot 4121 is defined in a side wall of the second end 412. The first stop part 4111 is used for stopping the first end 411 inside the first abdominal wheel main body 2. The first locking stop plate 42 is clamped to the first locking slot 4121. The first locking stop plate 42 is used for locking the second end 412 inside the second abdominal wheel main body 3, so that the second abdominal wheel main body 3 and the first abdominal wheel main body 2 are combined to form a whole. Specifically, the first locking device 4 further includes a first elastic restoration device 43 and a second elastic restoration device 44. The first elastic restoration device 43 is sleeved on the first locking pin 41. A first end of the first elastic restoration device 43 abuts against the first stop part 4111, and a second end of the first elastic restoration device 43 abuts against an inner wall of the first abdominal wheel main body 2. A first end of the second elastic restoration device 44 abuts against the first locking stop plate 42, and a second end of the second elastic restoration device 44 abuts against an inner wall of the second abdominal wheel main body 3. The first elastic restoration device 43 is used for pushing and locking the first locking slot 4121 to the first locking stop plate 42. The second elastic restoration device 44 is used for pushing and locking the first locking stop plate 42 to the first locking slot 4121. Furthermore, first locking openings 421 are defined in the first locking stop plate 42. The first elastic restoration device 43 is used for pushing and pressing the first locking slot 4121 against an outer surface of the first locking stop plate 42.

Furthermore, both the first elastic restoration device 43 and the second elastic restoration device 44 are springs. Through the above structure, the second end 412 of the first locking pin 41 sequentially passes through the first insertion opening 21 and the second insertion opening 31. The first stop part 4111 is used for stopping the first end 411 inside the first abdominal wheel main body 2. The first locking stop plate 42 is clamped to the first locking slot 4121. The first elastic restoration device 43 is used for pushing and pressing the first locking slot 4121 against the outer surface of the first locking stop plate 42. The second elastic restoration device 44 is used for pushing the first locking stop plate 42, so that the inner wall of the first locking opening 421 is pressed against the first locking slot 4121, preventing the second end 412 from being disengaged from the first insertion opening 21 and the second insertion opening 31, and locking the second end 412 of the first locking pin 41 to the second abdominal wheel main body 3, thereby combining the second abdominal wheel main body 3 with the first abdominal wheel main body 2 to form a whole. Moreover, when it is necessary to separate the first abdominal wheel main body and the second abdominal wheel main body 3 from each other, an external force greater than the elastic restoration force provided by the second elastic restoration device 44 and the first elastic restoration device 43 can be applied to the first locking stop plate 42, which can move the first locking stop plate 42 towards a direction away from the first locking slot 4121 to disengage from the first locking slot 4121, so that the second end 412 of the first locking pin 41 can be disengaged from the second insertion opening 31 to release the locking between the first abdominal wheel main body 2 and the second abdominal wheel main body 3, and the first abdominal wheel main body 2 and the second abdominal wheel main body 3 can be separated for use. For example, in some scenarios, the user can use one of the first abdominal wheel main body 2 and the second abdominal wheel main body 3 for abdominal training, and the other of the first abdominal wheel main body 2 and the second abdominal wheel main body 3 can be used for other people's abdominal training, so that the user can perform abdominal training with others at the same time, which is particularly suitable for fitness coaches to guide students in abdominal training.

[0038] In this embodiment, the main body part 1 is equipped with a first mounting housing 5, a universal wheel 51, and a second locking device 52. The universal wheel 51 is equipped with a first mounting member 511 and a wheel part 512. The wheel part 512 is rotatably connected to the first mounting member 511. The first mounting member 511 is rotatably connected to the first mounting housing 5. The second locking device 52 is movable between a second locking position and a second unlocking position. When the second locking device 52 moves to the second locking position, the second locking device 52 locks the first mounting member 511 to the first mounting housing 5, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5. When the second locking device 52 moves to the second unlocking position, the locking between the first mounting member 511 and the first mounting housing 5 is released, so that the first mounting member 511 is rotatable relative to the first mounting housing 5. Through the above structure, the main body part 1 is equipped with the first mounting housing 5, the universal wheel 51, and the second locking device 52. The universal wheel 51 is equipped with the first mounting member 511 and the wheel part 512. The wheel part 512 is rotatably connected to the first mounting member 511. The first mounting member 511 is rotatably connected to the first mounting housing 5. The second locking device 52 is movable between the second locking position and the second unlocking position. When the second locking device 52 moves to the second locking position, the second locking device 52 locks the first mounting member 511 to the first mounting housing 5, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5. When the second locking device 52 moves to the second unlocking position, the locking between the first mounting member 511 and the first mounting housing 5 is released, so that the first mounting member 511 is rotatable relative to the first mounting housing 5. Therefore, the user can lock the first mounting member 511 to the first mounting housing 5 through the second locking device 52, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5, the first mounting member 511 is fixed, and the wheel part 512 can only move in a directional manner, thereby allowing the user to concentrate on training the muscle group that needs to be trained. When a plurality of muscle groups need to be trained, the second locking device 52 can be moved to the second unlocking position, and the locking between the first mounting member 511 and the first mounting housing 5 can be released, so that the first mounting member 511 is rotatable relative to the first mounting housing 5, and the wheel part 512 is movable in multiple directions, making it convenient for the user to train different muscle groups of the body by adjusting a direction of movement of the wheel part 512.

[0039] In this embodiment, the second locking device 52 includes a first position limiting elastic buckle 521. A first mounting hole 5111 is defined in the first mounting member 511. When the second locking device 52 moves to the second locking position, the first position limiting elastic buckle 521 is positioned inside the first mounting hole 5111, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5. When the second locking device 52 moves to the second unlocking position, the first position limiting elastic buckle 521 disengages from the first mounting hole 5111, so that the first mounting member 511 is rotatable relative to the first mounting housing 5. The second locking device 52 also includes a second position limiting elastic buckle 522. When the second locking device 52 moves to the second locking position, the first position limiting elastic buckle 521 or the second position limiting elastic buckle 522 is positioned in the first mounting hole 5111, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5. When the second locking device 52 moves to the second unlocking position, the first position limiting elastic buckle 521 or the second position limiting elastic buckle 522 disengages from the first mounting hole 5111, so that the first mounting member 511 is rotatable relative to the first mounting housing 5. Specifically, the first position limiting elastic buckle 521 is positioned on a left side of the first mounting member 511, and the second position limiting elastic buckle 522 is positioned on a front side of the first mounting member 511. When the first position limiting elastic buckle 521 is connected to the first mounting hole 5111, the first mounting member 511 is not rotatable relative to the first mounting housing 5, and the first mounting member 511 and the wheel part 512 are longitudinally locked. When the second position limiting elastic buckle 522 is connected to the first mounting hole 5111, the first mounting member 511 is not rotatable relative to the first mounting housing 5, and the first mounting member 511 and the wheel part 512 are transversely locked. Furthermore, the second locking device 52 also includes a locking ejector rod 523 and a connecting rod component 524. A second mounting hole 53 is defined in the first mounting housing 5. The locking ejector rod 523 penetrates into the second mounting hole 53.

The connecting rod component 524 is connected to the first position limiting elastic buckle 521 and the second position limiting elastic buckle 522. The connecting rod component 524 abuts against the locking ejector rod 523. When the locking ejector rod 523 rotates to the second unlocking position, the locking ejector rod 523 lifts the connecting rod component 524, the first position limiting elastic buckle 521, and the second position limiting elastic buckle 522, so that the first position limiting elastic buckle 521 and the second position limiting elastic buckle 522 are disengaged from the first mounting hole 5111, making the first mounting member 511 rotatable relative to the first mounting housing 5. When the locking ejector rod 523 rotates to the second locking position, the locking ejector rod 523 releases the lifting of the connecting rod component 524 and the first position limiting elastic buckle 521, and the locking ejector rod maintains the lifting of the second position limiting elastic buckle, so that the first position limiting elastic buckle 521 falls back into the first mounting hole 5111, making the first mounting member 511 not rotatable relative to the first mounting housing 5. Alternatively, when the locking ejector rod 523 rotates to the second locking position, the locking ejector rod 523 releases the lifting of the connecting rod component 524 and the second position limiting elastic buckle, and the locking ejector rod maintains the lifting of the first position limiting elastic buckle, so that the second position limiting elastic buckle falls back into the first mounting hole 5111, making the first mounting member 511 not rotatable relative to the first mounting housing 5. Furthermore, the locking ejector rod 523 is provided with a first avoidance groove 5231 and a lifting surface 5232. The first avoidance groove 5231 is configured for surrounding one part of an outer peripheral wall of the locking ejector rod 523, and the lifting surface 5232 is configured for surrounding another part of the outer peripheral wall of the locking ejector rod 523. When the locking ejector rod 523 rotates to the second unlocking position, the lifting surface 5232 of the locking ejector rod 523 abuts against the connecting rod component 524, and the lifting surface 5232 of the locking ejector rod 523 lifts the connecting rod component 524, the first position limiting elastic buckle 521, and the second position limiting elastic buckle 522, so that the first position limiting elastic buckle 521 and the second position limiting elastic buckle 522 are disengaged from the first mounting hole 5111, making the first mounting member 511 rotatable relative to the first mounting housing 5. When the locking ejector rod 523 rotates to the second locking position, the lifting surface 5232 separates from a part of the connecting rod component 524, the part of the connecting rod component 524 is capable of falling back into the first avoidance groove 5231, the locking ejector rod releases the lifting of the first position limiting elastic buckle, and the locking ejector rod maintains the lifting of the second position limiting elastic buckle, so that the first position limiting elastic buckle 521 is capable of being restored and falling back into the first mounting hole 5111, making the first mounting member 511 not rotatable relative to the first mounting housing 5. Alternatively, when the locking ejector rod 523 rotates to the second locking position, the lifting surface 5232 separates from a part of the connecting rod component 524, the part of the connecting rod component 524 is capable of falling back into the first avoidance groove 5231, the locking ejector rod releases the lifting of the second position limiting elastic buckle, and the locking ejector rod maintains the lifting of the first position limiting elastic buckle, so that the second position limiting elastic buckle 521 is capable of being restored and falling back into the first mounting hole 5111, making the first mounting member 511 not rotatable relative to the first mounting housing 5. The second locking device 52 also includes a first knob 525. The first knob 525 is connected to the locking ejector rod 523, so that rotation of the first knob 525 is capable of driving the locking ejector rod 523 to rotate. Furthermore, the connecting rod component 524 includes a first connecting rod 5241 and a second connecting rod 5242. The first avoidance groove 5231 includes a first groove unit 52311 and a second groove unit 52312. The first groove unit 52311 and the second groove unit 52312 are respectively positioned on two sides of the lifting surface. The first connecting rod 5241 is connected to the first position limiting elastic buckle 521, and the first connecting rod 5241 is pressed against the locking ejector rod 523. The second connecting rod 5242 is connected to the second position limiting elastic buckle 522, and the second connecting rod 5242 is pressed against the locking ejector rod 523. When the locking ejector rod 523 rotates to the second unlocking position, the lifting surface 5232 of the locking ejector rod 523 abuts against the first connecting rod 5241 and the second connecting rod 5242, the lifting surface 5232 of the locking ejector rod 523 lifts the first connecting rod 5241, the second connecting rod 5242, the first position limiting elastic buckle 521, and the second position limiting elastic buckle 522, so that the first position limiting elastic buckle 521 and the second position limiting elastic buckle 522 are disengaged from the first mounting hole 5111, making the first mounting member 511 rotatable relative to the first mounting housing 5. When the locking ejector rod 523 rotates to the second locking position, the lifting surface 5232 separates from the first connecting rod 5241, the lifting surface maintains the lifting of the second connecting rod, and the first connecting rod 5241 is capable of falling back into the first groove unit 52311, so that the first position limiting elastic buckle is capable of being elastically restored and falling back into the first mounting hole 5111, making the first mounting member 511 not rotatable relative to the first mounting housing 5. Alternatively, when the locking ejector rod 523 rotates to the second locking position, the lifting surface 5232 separates from the second connecting rod, the lifting surface maintains the lifting of the first connecting rod, and the second connecting rod is capable of falling back into the second groove unit, so that the second position limiting elastic buckle is capable of being elastically restored and falling back into the first mounting hole 5111, making the first mounting member 511 not rotatable relative to the first mounting housing 5. The first position limiting elastic buckle 521 and the second position limiting elastic buckle 522 each include a position limiting column 5221 and a first spring 5222. The main body part 1 is equipped with a first position limiting plate 5223 and a second position limiting plate 5224. The first position limiting plate 5223 and the second position limiting plate 5224 are each provided with a position limiting hole 52241. The position limiting column 5221 is positioned inside the position limiting hole 52241, and the position limiting column 5221 is slidable inside the position limiting hole 52241. The first spring 5222 is sleeved on the position limiting column 5221. One end of the first spring 5222 abuts against an inner wall of the first position limiting plate 5223, and an opposite end of the first spring 5222 abuts against the second position limiting plate 5224. A positioning convex block 52211 is configured for extending from a side wall of the position limiting column 5221, and the positioning convex block 52211 penetrates through the first spring 5222, so that the first spring 5222 is capable of pushing the position limiting column 5221 to move into the first mounting hole 5111. Through the above structure, when it is necessary to lock the first mounting member 511 to the first mounting housing 5, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5 to make the wheel part 512 move in a directional manner, only the first knob 525 needs to be rotated. The rotation of the first knob 525 drives the locking ejector rod 523 to rotate until the lifting surface 5232 abuts against the first connecting rod 5241, allowing the first connecting rod 5241 to fall back into the first groove unit 52311. The lifting surface keeps the second connecting rod lifted, allowing the first spring 5222 to be elastically restored and push the position limiting column 5221 to fall back into the first mounting hole 5111, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5, thereby fixing the direction of movement of the wheel part 512. Alternatively, when it is necessary to lock the first mounting member 511 to the first mounting housing 5, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5 to make the wheel part 512 move in a directional manner, only the first knob 525 needs to be rotated. The rotation of the first knob 525 drives the locking ejector rod 523 to rotate until the lifting surface 5232 separates from the second connecting rod 5242, allowing the second connecting rod to fall back into the second groove unit. The lifting surface maintains the lifting of the first connecting rod, allowing the first spring 5222 to be elastically restored and push the position limiting column 5221 to fall back into the first mounting hole 5111, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5, thereby fixing the direction of movement of the wheel part 512. When it is necessary to release the locking between the first mounting member 511 and the first mounting housing 5, so that the first mounting member 511 is not rotatable relative to the first mounting housing 5 to make the wheel part 512 move in a universal manner, only the first knob 525 is needed to be rotated. The rotation of the first knob 525 drives the locking ejector rod 523 to rotate until the lifting surface 5232 abuts against the first connecting rod 5241 and the second connecting rod 5242, so that the lifting surface 5232 of the locking ejector rod 523 lifts the first connecting rod 5241, the second connecting rod 5242, and the position limiting column 5221, and the first spring 5222 is compressed to make the position limiting column 5221 detach from the first mounting hole 5111, so that the first mounting member 511 is rotatable and adjustable relative to the first mounting housing 5, thereby adjusting a rotation direction of the wheel part 512.
