Clip assembly for clamping a test-piece with two end portions which form an angle therebetween

摘要

A clip assembly includes a main block with a tapered internal wall confining a receiving space to receive slidably and engageably a pair of clamps therein. The clamps define a gap therebetween. The clamps further define an elongated engaging groove at its upper portion and extends transversely to the gap which receives engageably two connectors with two connecting rods extending out from the engaging groove to connect a circular disc disposed above the clamps. The disc has a centrally located threaded through-hole. A cover member has a through-hole aligned with the threaded through-hole of the disc and mounted securely on the rigid block to cover the receiving space. A regulating screw has a threaded portion engaged threadedly in the threaded through-hole of the circular disc and a head portion engaged rotatably by the periphery of the through-hole of the cover member so as to prevent the head portion from moving axially when the regulating screw is rotated about its axis.
