In the invention, firstly, a base 1 is placed on a sickbed, then thighs of a pregnant woman are respectively placed in a first arc-shaped supporting plate 5 and a second arc-shaped supporting plate 6, shanks of the pregnant woman are placed in a third arc-shaped supporting plate 7 and a fourth arc-shaped supporting plate 8, then a rotating wheel 12 is screwed, the rotating wheel 12 drives a second gear 10 to rotate through a large rotating shaft 11, the second gear 10 drives a first gear 9 to rotate through a double-sided rack 13, the first gear 9 drives a first swinging plate 3 to swing, the first swinging plate 3 drives a second swinging plate 4 to swing while moving upwards, so that the thighs and the shanks of the pregnant woman can exercise to prevent edema of the lower limbs of the pregnant woman, the pregnant woman can step on a large wedge block 19, a large spring 21 provides elastic force assistance for the large wedge block 19, and the first supporting rod 14 and the second supporting rod 15 can support the double-sided rack 13, the first and second shutters 16 and 17 can block the double-sided rack 13 and prevent the double-sided rack 13 from falling off the first and second gears 9 and 10.
At this time, the first rubber cushion 31 and the second rubber cushion 32 are positioned below the thigh of the pregnant woman, and the third rubber cushion 33 and the fourth rubber cushion 34 are positioned below the calf of the pregnant woman, so that the comfort of the pregnant woman can be improved.
At the moment, the large wedge-shaped block 19 can move leftwards, meanwhile, the large ratchet block 41 can be clamped into the ratchet groove 181, the large wedge-shaped block 19 can be fixed, the large wedge-shaped block 19 is prevented from moving rightwards, the situation that the large wedge-shaped block 19 extrudes the feet of a pregnant woman is avoided, when the large wedge-shaped block 19 needs to move rightwards, the large ratchet block 41 can be pulled downwards, the small slot 411 is pulled to the position of the large pin rod 43, then the large pin rod 43 is inserted into the small slot 411, the large ratchet block 41 can be fixed, at the moment, the large ratchet block 41 moves out of the ratchet groove 181, and interference on the movement of the large wedge-shaped block 19 cannot be caused.
At this time, the first latch 55 and the second latch 56 latch the double-sided rack 13, so that the first swing plate 3 can be fixed, when the first swing plate 3 needs to swing, the first pin rod 52 can be pulled out from the first pin hole 141, then the movable plate 51 is pulled forward, the first latch 55 and the second latch 56 are removed from the double-sided rack 13, when the second pin rod 53 moves forward to the position of the second pin hole 151, the second pin rod 53 can be inserted downward into the second pin hole 151, so that the movable plate 51, the first latch 55 and the second latch 56 are fixed, then the first swing plate 3 can be swung upward, when the first swing plate 3 needs to be tilted upward, the second pin rod 53 can be pulled out from the second pin hole 151, and the movable plate 51 is pushed backward, so that the first latch 55 and the second latch 56 are returned backward to the original positions, and the double-sided rack 13 is clamped through the first clamping teeth 55 and the second clamping teeth 56, so that the double-sided rack is safe and reliable.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
