<FIG> and <FIG> are views schematically illustrating an operation process of the movement preventing unit according to the first embodiment.

As illustrated in <FIG> and <FIG>, the movement preventing unit <NUM> may be disposed inside the support bar <NUM>. Specifically, the movement preventing unit <NUM> may be accommodated in an accommodation space <NUM> provided inside the support bar <NUM>. The accommodation space <NUM> of the movement preventing unit <NUM> may be provided adjacent to the opening <NUM>.

The support bar <NUM> is coupled to the base <NUM> in a state in which the movement preventing unit <NUM> is accommodated inside the support bar <NUM>. Specifically, the support bar <NUM> is inserted into the coupling portion <NUM> of the base <NUM> in a state in which the movement preventing unit <NUM> is accommodated inside the support bar <NUM>. The support bar <NUM> inserted into the coupling portion <NUM> of the base <NUM> may be coupled to the base <NUM> by the fixing member <NUM>. When the support bar <NUM> is coupled to the base <NUM>, the movement preventing unit <NUM> may be operated using a tool <NUM> to reduce the gap between the support bar <NUM> and the base <NUM>. The tool <NUM> may be inserted into the insertion hole <NUM> formed on the bottom surface of the base <NUM> to press the movement preventing unit <NUM> upward in the height direction H of the stand <NUM>. As an example, the tool <NUM> may include a hexagon wrench, and the tool <NUM> may be fastened to a fastening groove <NUM> formed on the coupling pin <NUM>. When the tool <NUM> is rotated in a state in which the tool <NUM> is fastened to the fastening groove <NUM> of the coupling pin <NUM>, the coupling pin <NUM> moves upward in the height direction H of the stand <NUM>. At this time, the upward movement of the second guide block <NUM> in the height direction H of the stand <NUM> is restricted by interference with a locking jaw <NUM> formed on an inner surface of the support bar <NUM>, and the first guide block <NUM> is pushed upward in the height direction H of the stand <NUM> by the coupling pin <NUM>.

The moving block <NUM> protruding through the opening <NUM> is in contact with the inner surface of the coupling portion <NUM> of the base <NUM>. The degree of protrusion of the moving block <NUM> may be determined by a size of the coupling hole 210a of the moving block <NUM>.

As such, the gap between the support bar <NUM> and the base <NUM> may be reduced by the moving block <NUM> being in close contact with the inner surface of the coupling portion <NUM>.

The coupling portion <NUM> of the base <NUM> may include a first end portion 113a facing upward in the height direction H of the stand <NUM> and a second end portion 113b facing downward in the height direction H of the stand <NUM>.

When the support bar <NUM> is coupled to the base <NUM>, the movement preventing unit 200a may be operated using the tool <NUM> to reduce the gap between the support bar <NUM> and the base <NUM>. When the tool <NUM> is rotated in a state in which the tool <NUM> is fastened to the fastening groove <NUM> of the coupling pin <NUM>, the coupling pin <NUM> moves upward in the height direction H of the stand <NUM>. At this time, the upward movement of the moving block <NUM> in the height direction H of the stand <NUM> is restricted by interference with the locking jaw <NUM> formed on the inner surface of the support bar <NUM>, and the moving block <NUM> protrudes through the opening <NUM> by moving along the inclined surface <NUM> of the guide block <NUM>.
