Further, the rotating part comprises a disc and a strip, the second end of the screw rod penetrates through the base and extends to the outside to be fixed with one end of the disc, and the strip is vertically fixed at a position, close to the edge, of the disc.

Furthermore, the rotating part is a motor, and the second end of the screw rod is positioned in the inner cavity of the base and connected with the motor.

Furthermore, a pulley with a foot brake is arranged on the base.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) through rotating the remote lever or using the motor, thereby make the lead screw rotate and make two sets of rod cover move to make the connecting rod slide or glide on with the slider, thereby make first branch can the up-and-down motion, make the spheroid that second branch bottom set up can rise or descend suitable height, the training of being convenient for.
