In order to enable the sliding rod 4 to move back and forth, a left-right-direction fixed shell 6 is arranged at the rear end of the chair frame 1, a left-right-direction rotating shaft 7 is connected in the fixed shell 6 in a rotating mode, a left end and a right end of the rotating shaft 7 respectively extend out of the fixed shell 6 and are coaxially provided with cams 8, the lower end of the sliding rod 4 extends out of the sliding groove 3 and is provided with left-right-direction push rods 9, and the opposite ends of the two push rods 9 are respectively hinged with the protruding ends of the cams 8 on the corresponding sides through connecting rods.

In order to make the rotating shaft 7 rotate, a left-right axial motor 11 is arranged in the fixed shell 6, a driving gear 12 is coaxially arranged at the output end of the motor 11, and a driven gear 13 capable of being meshed with the driving gear 12 is coaxially arranged on the rotating shaft 7.

In order to make the two grips 5 move back and forth alternatively, the two cams 8 are raised in opposite directions.

In order to enable the patient to better grasp the handles 5, the two handles 5 are both in an I shape, and fixing belts 14 are respectively arranged on the opposite surfaces of the handles 5.

In order to facilitate and push the device, the left side and the right side of the rear end of the chair frame 1 are respectively provided with armrests 15 which are positioned at the upper end and are in the front-back axial direction, and the lower end of the chair frame 1 is provided with a plurality of universal wheels 16.

When the utility model is used, a patient sits on the chair frame 1, the two hands respectively hold the handles 5 on the same side, the free ends of the fixing belts 14 are respectively pulled, and the two hands of the patient are respectively fixed on the handles 5 on the same side;

starting a motor 11, rotating the motor 11 clockwise, driving a driving gear 12 to rotate clockwise by the motor 11, driving the driving gear 12 to rotate anticlockwise by meshing a driven gear 13, driving a rotating shaft 7 by the driven gear 13 to rotate anticlockwise synchronously, driving two cams 8 to rotate anticlockwise, driving the convex end of the cam 8 on the right side to rotate backwards at the moment, driving a push rod 9 on the corresponding side of the cam 8 on the right side to move backwards by the cam 8 on the right side through a connecting rod 10 hinged with the cam 8, driving a handle 5 on the corresponding side of the push rod 9 to move backwards by a sliding rod 4, driving a hand on the corresponding side of a patient to move backwards by the handle 5, and enabling the arm on the corresponding side of the patient;
