[0006] The utility model has the beneficial effects that: the seat assembly can be adjusted and fixed at a suitable angle to ensure that the user's chest and abdomen can be fully supported and fitted to meet the back stretching at different angles; the height of the adjustable handlebar assembly can be quickly adjusted and stably locked, so that the user can adjust to a comfortable use height according to his own height.

[0007] In order to ensure the stability of the seat assembly movement;

[0008] As a further improvement of the above technical solution: the number of guide rails is two, and the number of sliding seats slidingly installed on each guide rail is two.

[0009] The beneficial effects of the improvement are: the setting of the two groups of sliding seats and guide rails can effectively improve the stability of the seat assembly movement when the user sits on the cushion.

[0010] In order to ensure the stability of the connection between the positioning slot and the positioning pin;

[0011] As a further improvement of the above technical solution: the positioning slot is inclined from top to bottom to the direction away from the hinge.

[0012] The beneficial effects of the improvement are: the inclined positioning slot can provide stable support for the backrest when the included angle between the backrest and the cushion is not greater than 90 degrees.

[0013] In order to conveniently adjust the angle of the backrest;

[0014] As a further improvement of the above technical solution: the number of positioning slots is multiple, and they are equally spaced on the positioning plate.

[0015] The beneficial effects of the improvement are: by placing the positioning pin into the corresponding positioning slot, stable support can be provided for the backrest at different angles.

[0016] In order to conveniently adjust the height of the handlebar;

[0017] As a further improvement of the above technical solution: the number of positioning holes is multiple, and they are equally spaced around the axis of the pin shaft on the rotating arm.

[0018] The beneficial effects of the improvement are: by rotating the rotating arm to adjust the angle of the handlebar, and inserting the steel ball latch into the through hole on the rotating arm and the corresponding positioning hole, the use height of the handlebar can be conveniently adjusted and locked.

[0019] In order to improve the comfort of the handlebar;

[0020] As a further improvement of the above technical solution: rubber anti-slip sleeves are sleeved on both ends of the handlebar.

[0021] The beneficial effects of the improvement are: the use of rubber anti-slip sleeves can increase the friction received by the user's hands, and also improve the comfort of the user's hands.

[0022] In order to improve the safety of the device;

[0023] As a further improvement of the above technical solution, the surface of the pedal is provided with an anti-skid convex structure.

[0024] The beneficial effect of the improvement is that the anti-skid convex design can avoid injuries caused by foot slipping during stretching.

[0025] The parts not involved in the device are the same as or can be realized by the prior art. BRIEF DESCRIPTION OF DRAWINGS
