In order to realize that the pedal plate 4 moves downwards to drive the chair back 1 to reciprocate left and right, the left end of the supporting rod 9 is positioned at the left side of the through groove 8 and is provided with a vertical rod 16, the left end surface of the vertical rod 16 is provided with a first rack 17, the front side and the rear side of the chair surface are provided with supporting plates 18 positioned at the left side of the vertical rod 16, a rotating shaft 19 horizontally arranged in the front-rear direction is arranged between the two supporting plates 18, the rotating shaft 19 is connected with the supporting plates 18 through a bearing, the rotating shaft 19 is provided with a gear 20 meshed with the first rack 17, the rotating shafts 19 at the front side and the rear side of the gear 20 are respectively provided with an incomplete gear 21, and the front side and the rear side of the chair back 1 are; the pedal plate 4 moves downwards, the gear 20 is driven to rotate clockwise through the meshing of the first rack 17 and the gear 20, the gear 20 rotates clockwise to drive the incomplete gear 21 to rotate clockwise, the incomplete gear 21 rotates to be meshed with the second rack 22 to drive the chair back 1 to move rightwards, the second pressure spring 15 is compressed, and after the meshing of the teeth of the incomplete gear 21 and the second rack 22 is finished, the chair back 1 moves leftwards to reset under the pressure of the second pressure spring 15.

In order to realize that the pedal plate 4 moves downwards and the chair back 1 moves back and forth for a plurality of times left and right in one period, the base circle diameter of the gear 20 is smaller than that of the incomplete gear 21, and a plurality of toothed parts are uniformly distributed on the incomplete gear 21; when the pedal plate 4 moves downwards, the toothed part of the incomplete gear 21 is matched with the second rack 22, the chair back 1 moves rightwards, the toothed part of the incomplete gear 21 is separated from the second rack 22, the chair back 1 moves leftwards and resets, and the reciprocating motion is carried out in such a way, so that the chair back 1 moves leftwards and rightwards repeatedly.

In order to realize that the pedal plate 4 does not move upwards, the chair back 1 does not move, a ring-shaped block 23 is fixed on the rotating shaft 19 corresponding to each incomplete gear 21, a radial positioning hole 24 is formed in the ring-shaped block 23, a radial positioning pin 25 is installed in the positioning hole 24 in a clearance mode, the positioning pin 25 can move in the positioning hole 24, a tension spring 26 is sleeved on the positioning pin 25, one end of the tension spring 26 is fixed on the ring-shaped block 23, the other end of the tension spring 26 is fixed on the positioning pin 25, the outer end of the positioning pin 25 is located at the outer end of the ring-shaped block 23 and is an inclined plane with a lower left part and a higher right part, and a plurality of wedge-shaped blocks 27 matched with the positioning pin 25 are evenly distributed on the circumference; when the pedal plate 4 moves downwards and the rotating shaft 19 rotates clockwise, the incomplete gear 21 can be driven to rotate through the matching of the positioning pin 25 and the wedge block 27; when the pedal plate 4 moves upwards and the rotating shaft 19 rotates anticlockwise, the wedge block 27 pushes the positioning pin 25 to move inwards, the tension spring 26 is pulled to deform, after the inclined surface of the positioning pin 25 is separated from the wedge block 27, the positioning pin 25 moves outwards to reset under the action of the tension spring 26, and therefore the incomplete gear 21 cannot rotate.

Before the device is used, the pedal plate 4 is positioned at the uppermost end of the displacement, the first compression spring 12 is positioned at the original length, the chair back 1 is positioned at the leftmost side of the displacement, and the second compression spring 15 is positioned at the original length;

when the device is used, an old man sits on a chair surface on the right side of a chair back 1, the back faces to the chair back 1, two feet are placed on a pedal plate 4, then a leg applies force to step down the pedal plate 4, the pedal plate 4 moves downwards to enable a first pressure spring 12 to be pressed and deformed, when the pedal plate 4 moves downwards, a gear 20 is driven to rotate clockwise through the meshing of a first rack 17 and the gear 20, the gear 20 rotates clockwise to drive an incomplete gear 21 to rotate clockwise, the incomplete gear 21 rotates and is meshed with a second rack 22 to drive the chair back 1 to move rightwards, the back of the old man is slapped, a second pressure spring 15 is compressed, after the teeth of the incomplete gear 21 are meshed with the second rack 22, the chair back 1 moves leftwards and resets under the pressure of the second pressure spring 15, the chair back 1 is separated from the back of the old man, and the toothed parts of the incomplete gear 21 are circumferentially and uniformly distributed, so that in the process that the pedal plate 4, therefore, in the process of moving downwards, the chair back 1 moves left and right in a reciprocating way, and continuously slaps the back of the old and leaves; when the pedal moves downwards to the lowest end of the displacement, the pedal can be loosened, the pedal drives two feet to move upwards under the action of the pressure of the first pressure spring 12, when the pedal 4 moves upwards and the rotating shaft 19 rotates anticlockwise, the wedge block 27 pushes the positioning pin 25 to move inwards, the tension spring 26 is pulled to deform, after the inclined surface of the positioning pin 25 is separated from the wedge block 27, the positioning pin 25 moves outwards and resets under the action of the tension spring 26, and therefore the incomplete gear 21 cannot rotate; so, reciprocal presser foot footboard of stepping on can be so that old man's shank strength obtains taking exercise to when shank strength obtains taking exercise, back of the chair 1 constantly slaps old man's back, makes old man's back obtain relaxing.

In addition, when the chair back 1 is at the leftmost end of its displacement, the elderly can lean against the rollers 2 on the chair back 1 and then move their backs up and down, so that the rollers 2 roll, thereby enabling the elderly to get better exercise of their backs and waists.

The utility model discloses a cylinder 2, ball 3, the mating reaction of running-board can be so that cylinder 2 constantly patts old man's back for old man's back obtains abundant exercise.

The utility model discloses a set up cylinder 2, the old man can hug closely cylinder 2 at the back, reciprocates the back for back and waist are tempered.

The utility model discloses an incomplete gear 21, second rack 22, the mating reaction of the back of the chair 1 etc. can wait to fully take exercise at the waist, can make the strength of shank obtain taking exercise simultaneously to when the old man takes exercise, can have a rest at any time, be favorable to old man's health more.
