And, the rear surface between the second receivers 140 is cut in an oblique shape to form an inclined shape, and rotates to come into contact with the second insertion port 130 and restrict the rotational range.

Alternatively, when the core chain module 100 rotates in a horizontal state, the second insertion hole 130 is inserted into the second receiving hole 140. At this time, an interference member 170 positioned on the same line as the second receiving hole 140 is formed at the rear of the second insertion hole 130 so that the second receiving hole 140 is connected to the second insertion hole 130. It is also possible to constrain the rotational range according to the interference with the interference member 170 while rotating while including.

The rotation accommodating grooves 150 are dug to correspond to each other in the front and rear of the center of the core chain module 100, and the core chain module 100 is positioned in close contact with the front and rear, and is symmetrical when placed facing each other. It is made of a shape to accommodate the curve of the elastic band (20).

The coupling intermittent sphere 43 is coupled across the first insertion groove 41 and the second insertion groove 42 to control the disengagement of the protruding insertion aperture 33 .

At this time, the first insertion groove 41 and the second insertion groove 42 are made of a round shape and cut outward to form a cut surface 44, and both ends according to the cut are made to have elasticity so that the coupling is interrupted. The sphere 43 is forcibly fitted into the first insertion groove 41 and the second insertion groove 42 to control the dropping of the protruding insertion hole 33.

At this time, if the coupling intermittent sphere 43 is described in more detail, it includes an intermittent body 431 and a shock absorbing hole 432.

The intermittent body 431 is made of a cylindrical elastic material.

The shock absorbing hole 432 represents a hole cut through a portion of the cross section of the intermittent body 431 in the front-back direction.

At this time, the surface of the intermittent body 431 protrudes outward from the core chain module 100 so that the intermittent body 431 comes into contact with the ground.

As the intermittent body 431 is formed in a cylindrical shape, it is possible to make a line contact rather than a surface contact when contacting the ground, thereby reducing the contact cross section. As a result, dust compared to surface contact can be reduced, and the shock absorbing hole 432 presses and crushes the shock absorbing hole 432 when the control body 431 contacts the ground, thereby absorbing shock. . In addition, since the intermittent body 431 is made of an elastic material, it is possible to reduce noise more than metal or plastic when in contact with the ground.

The above embodiment is merely an example, and other embodiments variously modified therefrom are possible to those skilled in the art.
