However, also in the implementation of this embodiment, the applicant has found that it has the following drawbacks:

1. during the interval adjustment, because the user sits on the seat cushion 24 and supports the armrest 13 with both hands, the contact area between the telescopic rod 23 and the cross frame 4 is large, after the front and the back are stressed, the friction resistance between the cross frame 4 and the telescopic rod 23 is large, the load of the motor 21 is increased, and the motor 21 needs to bear the friction resistance brought by all the weight of the user.

2. Secondly, a front and back torsion is applied to the armrest 13 and the seat cushion 24, which causes a slight torsion between the front and back telescopic rods 23 and the lead screw 22, i.e. the output shaft of the motor 21 is pressed down, which easily causes the screw thread deformation of the lead screw, and the load change fluctuates.

3. Because utilize the cylinder to stretch out and draw back in this scheme, the cylinder can't have accurate stroke when adjusting, need join in marriage devices such as compressor simultaneously and increased the cost.

Therefore, how to provide an electric adjusting mechanism with stable structure and difficult damage, and the height and distance of the armrest and the seat cushion can be accurately and electrically adjusted is a problem to be solved.

Meanwhile, as a parturient needs a certain movement space especially when entering the first active stage of labor after childbirth, a plurality of sports bicycles for pregnant and lying-in women (see publication No. CN206444079U, 2017-08-29, a fetus position adjusting sports bicycle) are introduced into the domestic obstetrical ward of hospital for the use of the parturient, so as to provide the parturient with effective pelvis and lower limb movement, promote natural childbirth rate, relieve childbirth pain, increase the comfort of the parturient, reduce the lateral vaginal resection rate, relieve the perineal laceration degree, reduce the vaginal dystocia childbirth and caesarean yield and ensure the good health of the mother and baby.
