the connecting module 3 drives the third rotating shaft 42 to rotate, the third rotating shaft 42 drives one group of fixed wheels 41 to rotate, one group of fixed wheels 41 respectively drives the rest fixed wheels 41, the first moving wheel 44 and the second moving wheel 45 to rotate through the rotating belt 43, and the first moving wheel 44 drives the pressing mechanism 6 to rotate;
the first moving wheel 44 drives the rotating member 61 to rotate, the rotating member 61 is in threaded connection with the adjusting base 62, the rotating member 61 drives the adjusting base 62 to move up and down, the adjusting base 62 drives the connecting base 63 to move up and down, and the connecting base 63 drives the pressing base 64 to move up and down through the telescopic member 65, so that the knee joint of the trainer is pressed down;
when the pressing rate of the pressing mechanism 6 needs to be adjusted, the power part 221 drives the gear 222 to rotate, the power part 221 is fixedly arranged on the moving seat 21, the gear 222 realizes the movement of the moving seat 21 by being meshed with the rack 223, the moving seat 21 drives the telescopic assembly 23 to move, the telescopic assembly 23 drives the connecting piece 24 to move on the first rotating shaft 26, the telescopic assembly 23 also drives the connecting piece 24 to turn over on the first rotating shaft 26 by being telescopic, the connecting piece 24 simultaneously drives the speed regulating gear set 27 to move and turn over on the first rotating shaft 26, the speed regulating gear set 27 realizes the meshing with the gears 222 with different diameters on the speed regulating gear set 28 by being movable and turned over, two groups of gears 222 with different diameters on the speed regulating gear set 27 are separately meshed with three groups of gears 222 with different diameters on the speed regulating gear set 28, the rotation ratios of the gears 222 with different diameters after being meshed are different, thereby realizing the adjustment of the rotating speed of the second rotating shaft 29;
when the rotating speed of the second rotating shaft 29 is adjusted, the rotating speed of the connecting module 3 is adjusted accordingly, the connecting module 3 adjusts the pressing speed of the pressing mechanism 6 in a manner of adjusting the rotating speed of the rotating mechanism 4, so that different trainers can train conveniently, and the requirement of the trainers with different physical qualities on small crotch soft opening training is met;
the working principle of the small crotch soft opening lifter for dance training is described above.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
