  • Patent number: 10448754
    Abstract: A clamp includes two clamping units spaced apart from each other, each of which includes a supporting mount, a tightening block and a tightening bolt. The supporting mount has an inclined guide face which faces an object to be clamped, and two through holes through which two fasteners respectively extend to engage an installation plane. The tightening block has a sliding face abutting against the inclined guide face, and is fastened on the supporting mount by the tightening bolt. A threaded portion of the tightening bolt passes through a passage hole of the tightening block to engage an engagement hole of the supporting mount, so that the tightening block is compelled by the tightening bolt to move along the inclined guide face.
