s1, the appliance is used by firstly pressing a reset R button of a wireless remote controller (14), sequentially operating a first motor (302), a second motor (303), a third motor (411), a first electronic push rod (408) and a second electronic push rod (6) to restore the original positions, so that a chair back support rod (12) is reset to the angle vertical to a support (2), and meanwhile, two leg pressing mechanisms (4) are parallelly closed to the front of the support (2), so that the appliance is convenient for an operator to use, is convenient for resetting by one key quickly in the process of over-stretching, relieves the pain of stretching and plays an effective protection role at the same time;

s2, when a user sits on the support (2), two groups of limit plates (409) respectively limit the positions of thighs, two third motors (411) positioned on the left side and the right side can be respectively started to rotate to one side by pressing C-1 and D-1, so that the two lead screws (403) are driven to rotate, two press plates (405) are enabled to displace towards the direction close to the third motors (411) under the limit of the two sliding grooves (402), and the two press plates (405) can displace towards the direction far away from the third motors (411) by respectively pressing C-2 and D-2, so that the user can adapt to users with different heights;

s3, when the angle of a pressing plate (405) needs to be adjusted to improve the rib pressing force, F-1 can be pressed to control two first electronic push rods (408) to be shortened in length at the same time, the first rack (410) drives an output gear (407) and a folding rod (406) to rotate towards the opposite side, the angle of the pressing plate (405) and a pushing frame (404) is reduced to achieve the rib pulling effect, the length of the two F-2 first electronic push rods (408) is extended at the same time, the angle of the pressing plate (405) and the pushing frame (404) can be increased and reset, and different rib pulling strengths can be effectively improved.

S4, pressing the E-1, controlling the extension length of the second electronic push rod (6), enabling the second electronic push rod to push the second rack (7) to slide towards the direction close to the transmission rod (8), enabling the transmission rod (8) meshed with the second electronic push rod to drive the rotating rod (9) to rotate towards one side close to the leg pressing mechanism (4) through the matching of the first transmission wheel (10) and the second transmission wheel (11), enabling the included angle between the chair back support rod (12) and the top surface of the support (2) to be small, enabling the length of the second electronic push rod (6) to be shortened through pressing the E-2, enabling the included angle between the chair back support rod (12) and the top surface of the support (2) to be large, enabling the two sleeves (13) to be clamped into the embedded sleeve grooves on one side of the support (2) at the largest angle, enabling the device to assist the exercise of stretching the lower waist and enhancing the whole body stretching and exercise;

s5, pressing A-1 or B-1 can respectively drive a first motor (302) located in two power mechanisms (3) to operate, and drive a transmission shaft (305) to rotate along the central axis through one group of first belt pulley (304) and a second belt pulley (306), so that a bevel gear (308) meshed with the transmission shaft drives a leg pressing mechanism (4) connected with the bevel gear to transversely rotate along the central axis of the bevel gear (308) through a support frame (310), thereby achieving a stretching effect, and pressing A-2 or B-2 can enable the first motor (302) to reversely rotate, thereby completing the resetting of a leg pressing plate (401);

s6, pressing A-3 or B-3 can respectively drive a second motor (303) located in the two power mechanisms (3) to operate, and drive a movable frame (307) to rotate along the central axis of the transmission shaft (305) through another group of first belt pulleys (304) and second belt pulleys (306), so that a leg pressing mechanism (4) connected with the support frame (310) is driven to longitudinally rotate along the central axis of the transmission shaft (305) through a bevel gear (308) and the support frame (310), the leg pressing plate (401) rotates up and down to further improve the stretching effect, and the second motor (303) can reversely rotate through pressing A-4 or B-4, so that the leg pressing plate (401) is reset.
