Embodiment

[0012] refer to figure 1 Shown, a kind of hunchback correction and chest muscle exerciser, 1 backboard, 2 bases, 3 movable shafts on both sides of the base, 4 left and right rocking arms, 5 extension springs, 6 waist belts. The backboard 1 corresponds to the body area of ​​the person. The rocker arm 4 takes the movable shaft 3 as the fulcrum to form a lever principle. The tension spring 5 tightens the tails of the two rocker arms 4, forming an opposite load force with the movement of the hand-held part of the rocker arm. The strength can be adjusted according to the number or thickness of the tension springs. It should be pointed out that those skilled in the art can make some improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.

Abstract

The invention discloses a device for correcting humpback and excising pectoral muscles. The device comprises a back board 1, a base 2, moving shafts 3 arranged on the two sides of the base, a left rocker arm 4, a right rocker arm 4, a tension spring 5 and a waist band 6. The back board 1 corresponds to the area of the back of the human body. The rocker arms 4 form a lever principle with the moving shafts 3 as the fulcrum. The tension spring 5 tensions the tails of the two rocker arms 4, and then loading force opposite to the motion of the handheld parts is formed and can be adjusted according to the number or the thickness of the tension spring. The device is simple in structure, low in cost, and convenient to use. The human body structure can be combined, the pectoral muscles are excised by the utilization of the lever principle, and the pectoral muscles are strengthened. The acting force generated when the pectoral muscles are excised can be combined with the counter acting force of the back board, the acting force and the counter acting force of the back board jointly act on the lumbar spinal cord and the spine, and bad somatotypes of the humpback and the rachitic back can be effectively corrected.
