ABSTRACT:
A base with clamp includes a clamping barrel, a fixing bolt, a sleeve seat and clamping plate. The clamping barrel has an open bottom and a top plate with a top hole and the top hole is surrounded by a clamping recess and has at least two recess holes. The fixing bolt has a clamping rod and a fastening plate, which juts out a fastening post. The clamping rod has a diameter less than the inner diameter of the top hole with rod threads. The fastening plate has a size corresponding to the clamping recess and has screw holes corresponding to the recess hole for the screws capable of passing through the screw holes and engaging with the recess hole. The sleeve seat has a base disk and extends upward an annular step and a cylindrical ring from the base disk for fitting with the clamping barrel so as to span the annular step and the cylindrical ring at the top thereof has a central hole for being passed through by the clamping rod. The clamping plate is flat and has a threaded hole for engaging with the rod threads. Hence, the clamping plate can ascend and descend along the clamping rod by way of the base disk and the clamping plate having a size greater than a hole of a held object and being placed on and under the hole respectively and the clamping barrel being turned so that the held object can be pressingly held or released.
