The above-mentioned components and their composition methods based on this creation, and then introduce their usage methods as follows:

When the user intends to securely clamp both legs in the leg clamping mechanism 100, he first presses the control button 272 of the manipulation device 20 by hand, so that the control button 272 is compressed and deformed by pressing the elastic member 26, and At the same time, the control button 272 drives the actuating rod 25 to move downwards, and the locking part 23 driven to rotate and connect is rotated along the connection point between the coupling part 21 as the center of the circle, so that the locking part 231 of the locking part 23 is aligned with the locking part 23. The locking part 222 of the plate 22 is separated, and at this time, when the control button 272 is pressed, the control lever 24 can be rotated in the opposite direction to the adjustment lever 11 (turning to the left in FIG. 4 ), And then drive the joint 21 to rotate in the same direction by the control rod 24, so that the first clamp pad group 31 that is sheathed on the joint part 21 is driven away from the second clamp pad group 32, so that the first clamp pad group 31 and the second clamp pad group 31 are separated from each other. The gap between the clamp pad group 32 is increased to the space where the user's legs can be placed. In particular, the above-mentioned action mode is only needed when the gap between the first clamping pad set 31 and the second clamping pad set 32 is not enough to insert the legs, such as between the first and second clamping pad sets 31 and 32. When the gap is enough for both legs to be inserted, the following actions can be performed directly without the above-mentioned actions.

Then, when the gap between the first and second clip pad groups 31, 32 is enough for both legs to be inserted, the user can step on each pedal 16 with both legs respectively, and then place the rear sides of the legs against each other respectively. On each of the first protective pads 313 of the first clip pad group 31, the control button 272 can be pressed by hand at this time, so that the locking part 231 of the locking part 23 and the locking part 222 of the locking plate 22 form a separated state. , and then hold the control lever 24 to rotate in the direction of the adjustment lever 11, so that the joint 21 can follow the control lever 24 and drive the second clamp pad group 32 to rotate in the direction of the adjustment rod 11 until each of the second clamp pad groups 32 The second pad 323 is closely attached to the front side of the legs, and then the control button 272 is released, the control button 272 will be pushed by the elastic force of the elastic member 26 and return to the state when no force is applied, and simultaneously pull the action The driving rod 25, the locking member 23 is pulled by the driving rod 25 and rotates, because the locking part 231 and the locking part 222 of the locking plate 22 are engaged with each other, so that the first clamping pad group 31 and the second clamping pad group 32 The positional relationship between them can be determined, and the user's legs can be clamped, so that the user can safely perform the fitness exercise of the handstand machine.

In addition, it is specifically stated here that since the locking part of the locking part and the locking part of the locking plate in this creation are in a state of engagement, it is a one-way adjustable and the other one-way non-adjustable fit; That is to say, when the control rod is intended to drive the joint part (or the second clamp pad group) to rotate toward the adjustment rod, it is not necessary to press the control button first to separate the catch part from the catch plate, but the control rod can be directly rotated to drive the adjustment rod. The locking part of the locking part moves to the next tooth groove of the locking part to engage; but when the control rod is intended to drive the joint part (or the second clamp pad group) to the reverse rotation of the adjustment rod, it cannot be directly controlled by the The control rod drives the coupling part to rotate, but the control button needs to be pressed first to separate the locking part from the locking plate, and then the coupling part can be rotated so that the locking part meshes with the last tooth groove of the locking part. Like this, when wanting to increase the gap between the first and second clip pad groups, it is necessary to press the control button and grip the control lever at the same time to complete. 1. When the gap between the two clamp pad groups is removed, it can be completed by only holding and moving the control lever, which greatly increases the convenience of the user in use.
