(10) As shown in FIGS. 1 and 6.

(11) The invention comprises a device frame 100 as a basis which is provided with two front and rear legs, and a seat 200 and armrests 300 located on the left and right sides are installed on a top of the device frame 100.

(12) Action structures are installed symmetrically on both sides of the device frame 100.

(13) The action structure comprises a first pivot 8 rotatably pivoted on the device frame 100.

(14) One end of the torsion spring 6 sleeved on the first pivot 8 is fixed to the device frame 100 by a limiting pin, and the other end of the torsion spring 6 is a hook-shaped torsion spring connecting hook 61.

(15) Rotating arms 5 are installed on the first pivot 8, and the rotating arm 5 comprises an upper rotating arm 51 and a lower rotating arm 52.

(16) A vertical through screw hole is provided on the horizontal upper rotating arm 51, and a screw portion 21 of a knob 2 is screwed in the through screw hole. A fixing pin 71 is provided on the upper rotating arm 51. The upper rotating arm 51 is also provided with a rear pulley 72 and a front pulley 73 in front of the fixing pin 71. The leg pad 3 is rotatably pivoted at a front end of the upper rotating arm 51 by a second pivot 32, and the leg pad 3 is provided with a leg contact surface 31.

(17) A transverse hollow tube 54 is provided at a front end of the inclined lower rotating arm 52, and an outer positioning hole 55 and an inner positioning hole 56 are respectively provided on side walls of the hollow tube 54 on both sides of the lower rotating arm 52.

(18) The device is provided with a pedal tube 4 which comprises a positioning tube 41 with a small diameter and a pedal tube body 42 with a large diameter; a positioning bead 43 is installed on the positioning tube 41, and a spring is provided inside the positioning tube 41 to push the positioning bead 43 out; the diameter of a side wall of the positioning tube 41 is smaller than the diameter of a positioning bead hole of the positioning bead 43, and a top of the positioning bead 43 is higher than an inner diameter of the hollow tube 54 when it is bounced up, but it will not fall out of the positioning bead hole.

(19) The device is provided with a retractable elastic resistance rope 1, which is a retractable elastic rubber rope with fixing rings 11 at both ends.

(20) As shown in FIGS. 1-3.

(21) When the abduction function is used: turn the knob 2 upward to disengage the torsion spring connecting hook 61 at an end of the torsion spring 6.

(22) Insert the positioning tube 41 of the pedal tube 4 into the hollow tube 54 from an inside. During the insertion process, an inner wall of the hollow tube 54 of the positioning bead 43 is pressed into the positioning bead hole and the spring is compressed. When the positioning bead 43 reaches the position of the outer positioning hole 55, the spring bounces up and pushes the positioning bead 43 into the outer positioning hole 55 and then gets stuck, so that the pedal tube 4 is positioned. At the same time, the step between the positioning tube 41 with a small diameter and the pedal tube body 42 with a large diameter can be pressed against an inner side of the hollow tube 54 to prevent the pedal tube 4 from moving outward.

(23) In other embodiments, a fixed pedal tube structure may be used, or a latch may be used instead of a positioning bead to connect the fixed pedal tube and the hollow tube.

(24) Rotate the leg pad 3 so that the leg contact surface 31 of the leg pad 3 faces inward.

(25) In other embodiments, the leg pad may be provided with leg contact surfaces on both sides so that the leg pad can be used directly without rotating it.

(26) Rotate the upper rotating arms 51 on both sides inward to a suitable position. The fixing ring 11 at one end of the retractable elastic resistance rope 1 is sleeved on the fixing pin 71 on the upper rotating arm 51 on one side, and then pulled obliquely to hold an inner side of the rear pulley 72 on the upper rotating arm 51 on the opposite side, and then bypass an outer side of the front pulley 73 on the upper rotating arm 51 on the opposite side, and then pulled horizontally to bypass an outer side of the front pulley 73 on the upper rotating arm 51 on this side, and hold an inner side of the rear pulley 72 on the upper rotating arm 51 on this side, and then pulled obliquely; the fixing ring 11 at the other end of the resistance rope 1 is sleeved on the fixing pin 71 on the upper rotating arm 51 on the opposite side.

(27) In this way, the two ends of the retractable elastic resistance rope 1 are fixed on the upper rotating arms 51 on both sides, and by pass the two front pulleys 73 serving as steering wheels and the two rear pulleys 72 serving as tensioning wheels in the middle.

(28) In other embodiments, the tensioning wheel may not be used and only the steering wheel may be used.

(29) In other embodiments, for the resistance rope: the two ends of the resistance rope can be directly fixed on the upper rotating arms on both sides; The resistance rope body can be an inelastic rope, with elastic elements such as springs connected to both ends of the resistance rope body; alternatively, elastic elements such as springs are provided in a middle of the resistance rope body. In this way, the combination of the resistance rope body and the elastic elements forms a retractable and elastic resistance rope.

(30) When in use: the user sits on the seat 200, holds the armrests 300 on the left and right sides, rests his legs on the leg contact surfaces 31 on the left and right sides, steps his feet on the pedal tube bodies 42 on the left and right sides, and moves his legs outward with force. At this time, the upper rotating arms 51 on both sides rotate outward, and the retractable elastic resistance rope 1 is stretched. The generated resistance needs to be overcome by the legs, thereby achieving the effect of hip abduction.

(31) As shown in FIGS. 4-6: When the adduction function is used: remove the retractable elastic resistance rope 1; rotate the upper rotating arms 51 on both sides outward to a suitable position; turn the knob 2 downward to insert it into the torsion spring connecting hook 61 at an end of the torsion spring 6.

(32) In other embodiments, instead of using a knob form that matches a threaded screw hole to match the torsion spring, a latch may be used to insert into the torsion spring connecting hook.

(33) In other embodiments, instead of using a torsion spring, other resistance structures may be used, such as a motor, or a spring with one end connected to the device frame. One end of the resistance structure is connected to the device frame, and the connecting hook at the other end can be engaged with or disengaged from the pin.

(34) Insert the positioning tube 41 of the pedal tube 4 into the hollow tube 54 from an outside until the positioning bead 43 reaches the position of the inner positioning hole 56. The spring bounces up and pushes the positioning bead 43 into the inner positioning hole 56 and gets stuck, so that the pedal tube 4 is positioned.

(35) Rotate the leg pad 3 so that the leg contact surface 31 of the leg pad 3 faces outward.

(36) When in use:

(37) The user sits on the seat 200, holds the armrests 300 on the left and right sides, rests his legs on the leg contact surfaces 31 on the left and right sides, steps his feet on the pedal tube bodies 42 on the left and right sides, and moves his legs inward with force. At this time, the upper rotating arms 51 on both sides rotate inward, the torsion spring 6 deforms, and the resistance generated needs to be overcome by the legs, thereby achieving the effect of hip adduction.
