Referring to FIG. 1, the grommet expander 100 includes a circular body portion 110, a plurality of rotation members 120, and a support 130.

Body 110 has an outer bearing 112 and the inner bearing 114 is coupled to the inside of the outer bearing 112 to perform a sliding movement. A plurality of first fastening holes 115 are formed at one side of the outer bearing 112. An arc-shaped guide groove 116 is formed below the outer bearing 112. That is, the guide groove 116 extends and extends by a predetermined length along the outer circumferential surface of the outer bearing 112. In addition, the handle 117 is coupled to the upper outer circumferential surface of the outer bearing 112.

A plurality of first hinge holes 118 are formed at one side of the inner bearing 114. A second fastening hole 119 penetrates in a vertical direction at a lower side of the inner bearing 114, and the second fastening hole 119 is a guide groove of the outer bearing 112 that pivots around the inner bearing 114. It always communicates with 116 in the vertical direction.

The rotating member 120 includes a first rotating part 121, a second rotating part 122, and a third rotating part 123 arranged at intervals of 120 degrees. The first rotating part 121, the second rotating part 122, and the third rotating part 123 are formed of a rod-shaped bracket 124.

A long groove 125 is formed at an upper side of each bracket 124, and a second hinge hole 127 is formed at a lower side of the long groove 125. The second hinge hole 127 corresponds to the first hinge hole 118 formed in the inner bearing 114. At the bottom of each bracket 124, the fitting protrusion 126 is integrally formed to protrude in a direction perpendicular to the bracket 124. The fitting protrusion 126 is inserted into the insertion hole H formed at the center of the grommet G.

Each of the rotating parts 121, 122, 123 and the outer bearing 112 includes a plurality of fastening bolts passing through the long groove 125 formed in the bracket 124 and the first fastening hole 115 formed in the outer bearing 112 ( 150). At this time, the long groove 125 is fastened to the outer bearing 112 serves as a guide of the fastening bolt 150 to be rotated along the outer bearing (112). Each of the rotating members 121, 122, and 123 and the inner bearing 114 pass through the second hinge hole 127 formed in the bracket 124 and the first hinge hole 118 formed in the inner bearing 114.
