The present invention relates to a screw clamp. The screw clamp includes: a clamp body having a vertical board type body part, a lower support part extended to a lower part of the body part vertically and integrally, and a staple-shaped aperture which is extended to an upper part of the body part vertically and integrally and comprises an upper support part in parallel with the lower support part, and into which a fixed object is inserted; a lower fastening hole formed to penetrate the lower support part up and down; an upper assembly hole which penetrates the upper support part while having multiple protrusions; a screw bolt which is fastened to the lower fastening hole through a screw for an upper part thereof to appear or be absent from the aperture; a shackle shaft and a jaw cam which are arranged to be held on the protrusion while being assembled at the upper assembly hole from bottom to top; and a shackle fastened to the shackle shaft exposed to an upper part of the upper assembly hole. A flat lower jaw is fixed to an upper plane of the screw bolt by a bearing while being able to rotate. A flat upper jaw is fixed to a lower plane of the jaw cap by a bearing while being able to rotate. The shackle shaft and the jaw cap are separated so that the shackle shaft can rotate. |
