PURPOSE: A regular-interval multi-spacer is provided to improve working efficiency by forming residual holes at regular intervals without additional measurement after a reference hole is formed. CONSTITUTION: A regular-interval multi-spacer is composed of a plurality of support blocks(100) having a through hole(110), a bush(200) inserted into the through hole, a first support rod(300) installed at the support block, and a second support rod(400) installed at the support block. The first support rod is fit into the outer circumference of the bush, and has first hinge coupling units(310). The second support rod is fit into the outer circumference of the bush, and has second hinge coupling units(410).
