[0081] When the latch cooperates with the arc-shaped plate, a plurality of insertion holes are arranged on the arc-shaped plate, the arc-shaped plate is arranged on the base frame assembly 1 or the support 21, one end of the latch is arranged on the support 21 or the base frame assembly 1 relative to the arc-shaped plate, and the other end of the latch is used to extend into any insertion hole on the arc-shaped plate and abut therewith, so as to lock the relative rotation between the support 21 and the base frame assembly 1; when the latch is separated from the insertion hole on the arc-shaped plate, the relative rotation between the support 21 and the base frame assembly is released.

[0082] Reference is made to the accompanying drawings Figure 2 In some embodiments, the first adjusting mechanism comprises a telescopic sleeve 23, a sliding piece 24 and a locking piece 25.

One end of the sliding piece 24 is slidably arranged in the telescopic sleeve 23, and the other end of the sliding piece 24 is rotatably arranged on the support 21 or the base frame 11 relative to the telescopic sleeve 23.

[0084] The rotatable connection between the telescopic sleeve 23 or the sliding piece 24 and the support 21 is located between the two ends of the support 21. Based on the relative rotation of the second rotating shaft 7, during the rotation of the support 21 relative to the base frame 11, the sliding piece 24 slides out of or into the telescopic sleeve 23 to cooperate with the rotation of the support 21 relative to the base frame 11, so as to change the included angle between the support 21 and the base frame 11.

[0085] The locking piece 25 includes but is not limited to a latch, a screw or a bolt. The locking piece 25 is arranged through the telescopic sleeve 23.

The locking piece 25 is used to be inserted into or pulled out of the limiting holes to lock or release the relative sliding between the sliding piece 24 and the telescopic sleeve 23.

[0086] When the locking piece 25 is inserted into the limiting hole, the relative sliding between the sliding piece 24 and the telescopic sleeve 23 is limited, and the support 21 cannot continue to rotate relative to the base frame 11. The athlete can perform leg kicking training based on the current rotation angle of the support 21 relative to the base frame 11.

[0087] When the locking piece 25 is pulled out of the limiting hole, the relative sliding between the sliding piece 24 and the telescopic sleeve 23 is restored, and the support 21 can rotate relative to the base frame 11. The athlete can adjust the rotation angle of the support 21 relative to the base frame 11, and then insert the locking piece 25 into the limiting hole, so that the extension direction of the support 21 is changed to another orientation, thereby meeting the requirement of the athlete to change the leg kicking direction for leg kicking training.

[0088] Reference is made to the accompanying drawings Figure 1 With the accompanying drawings Figure 2In some embodiments, the slide assembly 3 comprises a sliding seat 31 and a stepping member 32, the sliding seat 31 is slidably arranged on the slide rail assembly 2 and rotates with the slide rail assembly 2 based on the rotation shaft relative to the base frame assembly 1, the counterweight rod 4 is arranged on the sliding seat 31, and the stepping member 32 is arranged on the sliding seat 31. When the sliding seat 31 is pushed to slide to the closest position to the base frame assembly 1 through the stepping member 32, the axis of the counterweight rod 4 coincides with the axis of the rotation shaft.

[0089] Specifically, the sliding seat 31 is slidably arranged on the slide rail member 22, the sliding seat 31 further comprises a mounting seat and two pulleys, the two pulleys are rotatably arranged on the mounting seat, the mounting seat is slidably connected with the two slide rail members 22 through the two pulleys, and the counterweight rod 4 is fixedly arranged on both sides of the mounting seat. The counterweight rod 4 is used for loading counterweight, so as to increase the weight of the sliding seat 31 and add the resistance to the sliding of the sliding seat 31 relative to the slide rail member 22.

[0090] When the mounting seat drives the counterweight rod 4 to slide to the end of the slide rail member 22 closest to the base frame 11 to abut, that is, the position of the sliding seat 31 closest to the base frame assembly 1, the mounting seat stops sliding and abuts against the end of the slide rail member 22, and the axis of the counterweight rod 4 at this position coincides with the axis of the first rotation shaft 6 of the rotating end of the slide rail member 22. At this time, the athlete adjusts the rotation angle of the slide rail assembly 2 relative to the base frame 11 without additional force to prevent the sliding of the mounting seat relative to the slide rail member 22, and based on the principle of torque = force * force arm, the distance between the counterweight on the counterweight rod 4 and the axis of the first rotation shaft 6 is zero, that is, the force arm is zero. No matter how heavy the counterweight on the counterweight rod 4 is, the counteracting torque generated by the counterweight on the counterweight rod 4 when the slide rail assembly 2 rotates relative to the base frame 11 is zero. Therefore, it is not necessary to remove the counterweight before adjustment or bear the counteracting torque generated by the counterweight during adjustment, which is convenient for the athlete to save labor and adjust the slide rail assembly 2 to adjust the kicking direction.

[0091] The stepping member 32 is a cross bar extending along the width direction of the base frame 11, the stepping member 32 is arranged on the mounting seat, and the stepping member 32 is used to expand the stepping position of the athlete on the sliding seat 31.
