The rear clamping leg assembly 232 is pivotally assembled to the rear of the bottom side of the assembly tube 215, and includes a rear rod 236 pivotally assembled to the extension member assembly 212, and a rear abutment 237 assembled to the top side of the rear rod 236. The rear rod 236 is pivotally assembled to the rear side of the pedal 219, and an included angle θ 1 is formed between the axis of the rear rod and the extending direction of the rack portion 226. The tooth 233 is fixedly assembled to the bottom side of the rear rod 236, forms a predetermined angle θ 2 with the rear rod 236, and has a tooth portion 238 facing the rack portion 226 of the moving member 222. The slot 217 of the assembly tube 215 allows the tine 233 to extend into the assembly channel 216 and engage the rack portion 226.

The control unit 24 is operable to rotate relative to the auxiliary handstand unit 21 and includes a control member 241 and two linking members 242. The handling assembly 241 is pivotally assembled to the front side of the assembly tube 215 by a pivot head 243. One end of each linking member 242 is pivotally connected to the control member 241, and the other end is pivotally connected to the left and right sides of the rear rod 236 and located between the tooth plate 233 and the rear abutting members 237, so that when the control member 241 is operated to rotate, the linking members 242 can drive the rear clamping leg set 232 to rotate.

It should be noted that the number of the linking members 242 is not limited to two, and may be one according to actual requirements, and the linking member is pivotally connected between one of the left and right sides of the rear rod 236 and the control assembly 241.

Referring to fig. 5 to 7, the auxiliary inversion mechanism 2 can be switched between a rotation-stop state (see fig. 6) and a rotatable state (see fig. 7) with respect to the main support 1. In the rotation stop state, the tooth portion 238 of the tooth 233 of the rear clip leg set 232 does not engage with the rack portion 226 of the moving member 222 of the locking unit 22, and the second locking member 223 of the locking unit 22 and the first locking member 14 are hooked with each other, so that the auxiliary inverted mechanism 2 cannot rotate relative to the main support 1. In the rotatable state, the tooth portion 238 of the tooth 233 engages with the rack portion 226 of the moving member 222, and the second locking member 223 is disengaged from the first locking member 14, so that the auxiliary handstand mechanism 2 can rotate relative to the main support 1.

Before use, the handstand machine is in the rotation stopping state. In use, the feet of the user 9 are first moved from the auxiliary tread pad 15 onto the footboard 219 and the back rests against the back-up plate 214. At this time, the front side of the ankle of the user 9 abuts against the front pressing member 235 of the front clip leg group 231.

Then, the operation and rotation of the control assembly 241 is performed in the direction of a first arrow a1 toward the foot, so that the linkage 242 is pulled up by the control assembly 241, and the rear rod 236 of the rear clamping leg set 232 drives the rear abutting pieces 237 to rotate in the direction of a second arrow a2 toward the assembling tube 215, so that the included angle θ 1 between the axis of the rear rod 236 and the extending direction of the rack portion 226 is reduced until the tooth portion 238 of the tooth plate 233 engages with the rack portion 226 of the moving member 222, and then the moving member 222 is pressed down, and the rear abutting pieces 237 also abut against the rear side of the ankle 9 of the user. At this time, the second locking member 223 is linked with the moving member 222 and pressed downward in the direction opposite to the back-up member set 211, so as to disengage from the first locking member 14, and the handstand machine is converted to the rotatable state.

Referring to fig. 7 to 9, when the handstand machine is in the rotatable state, since the second locking member 223 is disengaged from the first locking member 14 and the rear leg clamping set 232 and the front leg clamping set 231 clamp the ankle of the user 9 together, the user 9 can use the auxiliary handstand mechanism 2 to assist the body of the user 9 to handstand along the direction of a third arrow a3 by holding the auxiliary handle portion 13.

In the present embodiment, the control assembly 241 is designed to be engaged with a gear plate disposed on the pivot head 243, so as to control the control assembly 241 not to rotate arbitrarily when not being operated. Since the manner of controlling the operation element 241 to stay at the predetermined rotation angle is numerous and is not the focus of the present invention, further description is not repeated herein.

When the inverted exercise is finished, the user 9 also assists the body to return to the upright posture under the head, upper and lower feet by holding the auxiliary grip portion 13 from the rear to the front. Then, the control component 241 is rotated in a direction opposite to the first arrow a1 away from the assembling tube 215, so that the linking component 242 drives the rear abutting component 237 to rotate away from the assembling tube 215, the tooth 233 is disengaged from the moving component 222, and the moving component 222 is moved upward in a direction adjacent to the backing component 211 by the resilient force of the resilient component 224, so that the second locking component 223 is also moved in the same direction to be hooked with the first locking component 14, and the rotation-stopping state shown in fig. 6 is recovered.

In summary, in the handstand machine of the present invention, by the design that the second locking member 223 of the locking unit 22 can be detachably engaged with the first locking member 14 of the main support 1 and the design that the teeth 233 of the rear clamping leg set 232 can be engaged with and press down the rack portion 226 of the moving member 222, when the clamping leg unit 23 does not clamp the foot of the user 9, the auxiliary handstand mechanism 2 cannot rotate relative to the main support 1 and is in the rotation-stopped state; when the foot clamping unit 23 clamps the feet of the user 9, the handstand machine is in the rotatable state, and the auxiliary handstand mechanism 2 rotates, so that the risk that the user 9 performs handstand in a dangerous state is avoided, and the safety of using the handstand machine is effectively improved. In addition, the locking unit 22 does not need to be operated by the user, but is performed simultaneously with the clamping of the feet, so that the handstand machine is very simple, convenient and intuitive to use, and the purpose of the invention can be achieved.

However, the above description is only an example of the present invention, and the scope of the present invention should not be limited by this, and all the simple equivalent changes and modifications made according to the claims and the contents of the patent specification should be included in the scope of the present invention.
