And, there is another advantage that the separation shaft supporting both arms support can be precisely and firmly adjusted by sliding and axial rotation.

The present invention having the configuration as described above will be described in detail with reference to the following drawings. 3 is an exploded perspective view of the golf swing assisting tool according to the present invention, Figure 4 is a plan view of Figure 1, Figure 5 is a perspective view showing the outer periphery expansion process of the separation shaft.

The present invention has a solid structure that maintains the triangle of the user's arms and shoulders, but is made with the focus on making it easy to wear both arms according to the user's body shape and taste, largely separated shaft (100) and , A pair of both arm supports 200 coupled to both ends of the spaced shaft 100 and a binding band 300 for connecting and disengaging the ends of the both arms support 200, wherein the spaced shaft 100 is Being located in front of the user's chest, the two arms support 200 is in the lower and lower side of the arm, the binding band 300 is wrapped around the outer side of the arm to bind the two arms support 200 to the arm.

The separation shaft 100 is composed of a fixed shaft 100 and a moving shaft 120, the fixed shaft 110 and the moving shaft 120 is a portion of the moving shaft 120, such as the structure of the cylinder and the piston, respectively Is linearly moved along the axis of the fixed shaft 110 in the state inserted into the fixed shaft 110.

The fixed shaft 110 is formed in a cylindrical shape with an open end, and the movable shaft 120 is formed with an outer circumference smaller than the inner circumference of the fixed shaft 110 to be fitted to the fixed shaft 110. The fixed shaft 110 and the movable shaft 120 form one axis of a specific length by being inserted and fixed inside the 110.

One of the main points of the present invention is a structure for fixing the moving shaft 120 on the inner wall of the fixing shaft 110.

An end portion of the movable shaft 120 inserted into the fixed shaft 110 is provided with an eccentric shaft portion 121 and an outer circumferential expansion tool 122 fitted to the eccentric shaft portion 121. 122, an eccentric hole 122a corresponding to the eccentric shaft portion 121 is formed, and when the outer circumferential extension 122 is inserted into the eccentric shaft portion 121 and rotates, the outer circumferential extension 122 is moved to the shaft. Protrusions are formed on the outer circumferential surface of the 120.

Referring to FIG. 5, the outer circumferential extension hole 122 has an outer circumferential surface having the same size as the moving shaft 120 in the initial state fitted to the eccentric shaft portion 121, but the outer circumferential extension hole 122 is When rotating about the eccentric shaft portion 121, a portion of the eccentric shaft portion 121 protrudes outward from the outer circumferential surface of the moving shaft 120.

Rotation of the outer circumferential extension 122 is caused by friction between the inner circumferential surface of the fixed shaft 110 and the outer circumferential surface of the outer circumferential extension 122 when the fixed shaft 110 and the movable shaft 120 are rotated relative to each other. As the outer circumferential extension 122 is formed longer, a larger contact area is formed with the inner circumferential surface of the fixed shaft 110, thereby improving reliability of such an operation.

Here, in order to improve the assemblability to form the initial state of the eccentric shaft portion 121 and the outer circumferential expansion opening 122, the eccentric shaft portion 121 protrudes to form a locking piece 121b on the outer circumference, In the outer circumferential extension 122 that is fitted to the eccentric shaft portion 121, a rotational displacement forming groove 122b having a width that can accommodate the locking piece 121b is formed so that the locking piece 121b forms the rotational displacement. Only the rotational displacement formed by the groove 122b can be moved relative to the outer circumferential extension 122.

In the embodiment shown in FIG. 5, the engaging piece 121b of the eccentric shaft portion is formed at the point farthest from the eccentric shaft to the outer circumferential surface of the movable shaft 120, and the rotational displacement forming groove 122b of the outer circumferential extension tool is shown. ) Is in contact with the engaging piece 121b at one end in an initial state, and the engaging piece 122 forms a rotational displacement that can protrude beyond the necessary width outside the moving shaft 120, the locking piece The rotational displacement is limited by the other end 121b so that the outer circumferential extension 122 rotates and moves only within the rotational displacement formed at both ends of the rotational displacement forming groove 122b.

The outer circumferential extension 122 has an open portion that can be expanded by pressure on one side thereof so that the outer circumferential extension 122 can be easily fitted to the eccentric shaft portion 121, and the outer circumferential extension 122 It is preferable to form the bent groove on the opposite side of the opening to reduce the outer circumferential thickness so that the opening is more easily expanded.

In the spaced shaft 100 having the structure as described above, when the movable shaft 120 is rotated in a state of being fitted to the fixed shaft 110, the outer circumferential extension 122 protrudes out of the outer circumferential surface of the movable shaft 120 to move the shaft. Since the fixed shaft 110 is clamped on the inner circumferential surface with the 120, the length of the spaced shaft 100 can be firmly adjusted by a simple operation of rotating the movable shaft 120 or the fixed shaft 100. In addition, fine length adjustment is easy.

The other one of the main points of the present invention is a coupling structure of the spaced shaft 100 and both arms 200, the two arms 200 has a semi-circular shape similar to the conventional but both ends of the spaced shaft 100 It is configured to be axially coupled by the fixed rotation shaft 400 to the two arms support 200 to be rotated about the fixed rotation shaft 400 without being fixedly coupled to the spaced shaft 100.

With reference to a perspective view showing a state in which both arms support of Figure 6 is rotated along the user's arm twist, when explaining the validity of the rotation structure of both arms support 200, if both arms and the arm at regular intervals of the swing fixed The triangular line of the shoulder can be maintained but the arm is twisted at different angles according to the position from the body. With the coupling structure as described above, the vertical rotation of the fixed rotation shaft 400 is formed during the angle deformation of the arm. The load corresponding to the angle can be canceled to reduce the shear force applied to the skin of the arm.

Another one of the main points of the present invention is a semi-circular binding band 300 for binding and releasing the open ends of the two arms support 200, one end of the binding band 300 of the two arms support 200 It is fixed to one end, and the other end is coupled to the Velcro 310 is configured to be detachable on the other end of the two arms support 200.

The two arms support the user through the operation of contacting the end of the binding band 300 to the Velcro 310 attached to the both arms support 200 in a state in which both arms support 200 is inserted into the inner lower side of the arm. Since it is easy to attach and detach to both arms because it binds the spaced end of the (200), it is easy to adjust to the user's arm size within the length range formed by the Velcro 310, and does not come off from the user when wearing conveniently Can be used.

The present invention by the configuration as described above, while being easy to attach to both arms, there is an effect that can be conveniently used without being separated from the user even without pressing using both arms when worn.

In addition, both arms support is rotated to the torsion of both arms according to the user's posture has another effect that does not impair the skin and muscles of the user even when repeated use.

And, there is another effect that the separation shaft for supporting both arms support can be adjusted precisely and firmly by sliding and axial rotation.
