This embodiment has two training modes:
the first training mode is as follows: when the small flying swallow training exercise device is used, the square-shaped handle 75 is pulled firstly, the square-shaped handle 75 is clamped in the third notch 760 of the upright post 76, so that the locking rod 71 is separated from the arc-shaped baffle 74, a person lies on the seat plate 4, the head of the person is placed at the notch 11 of the front plate 1 and supported by the rubber cushion, the knee part of the person is placed in the second notch and supported by the soft pocket cloth 31, then the head and the legs of the person warp upwards simultaneously, and when the person warps upwards, the torsion spring 40 drives the ends, far away from the seat plate 4, of the front plate 1 and the tail plate 3 to warp upwards so as to drive the heads and the legs of the person to warp upwards;
the moment of the V-shaped rod 401 of the torsion spring 40 is adjusted through different positions of the adjusting rod 50 in the adjusting device, so that the torsion of the torsion spring 40 is adjusted, the more the adjusting rod 50 moves towards two ends and is close to the front plate 1 and the tail plate 3, the larger the elasticity of the torsion spring 40 is, the lower the difficulty of training operation is, and a user can adjust the adjusting rod 50 according to the self condition, so that the self body quality is adapted;
a second training mode; when the folding chair is used, the square handle 75 is separated from the third notch 760, the second compression spring 73 tightly supports the locking rod 71, the free end of the locking rod 71 is supported against the inner side face of the arc-shaped baffle plate 74, a person lies on the seat plate 4, the head of the person is placed at the notch 11 of the front plate 1 and supported by the rubber cushion, the knee part of the person is placed in the second notch and supported by the soft pocket cloth 31, then the head and the legs of the person warp upwards simultaneously, and when the person warps, the torsion spring 40 drives the front plate 1 and the tail plate 3 to warp upwards at one end far away from the seat plate 4, so that the head and the legs of the person are driven to warp upwards; when the ends of the front board 1 and the tail board 3, which are far away from the seat board 4, tilt upwards to a certain angle, the locking rod 71 is pressed into the clamping hole 741 under the action of the second compression spring 73, so that the angles between the front board 1, the tail board 3 and the seat board 4 are fixed, and at the moment, the user can continue to tilt the head and the legs upwards to achieve the purpose of training;
after the training is finished, the square handle 75 is pulled to enable the locking rod 71 to be separated from the clamping hole 741, at the moment, the front plate 1 and the tail plate 3 can be pressed down by means of the self weight of the user, and therefore the user can conveniently get off the training device;
adopt the second kind training direction, the fixed angle between front bezel 1, tailboard 3 and the seat 4 is less than little flying swallow training exercise's standard training angle, and the user drives earlier by torsional spring 40 as to locking angle, relies on self to carry out the exercise of angle at the back again, to a certain extent, has also reduced the degree of difficulty of training.
The multifunctional training device for lumbar muscle strain rehabilitation provided by the invention is described in detail above. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core ideas. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
