A work piece clamping device is composed of a clamping block, a locking cover, a plate button, a support rod, a press rod, a tightening nut engaged with the press rod, and a fastening member. The clamping block is provided with a vertical wall for locating a work piece in place on a workbench top. The clamping block can be moved up and down along the support rod by the fastening member which is located under the workbench top and is movably fitted over the support rod. The clamping block is exerted on by the pressure of the plate button so as to hold securely the work piece on the workbench top.
