Abstract: An inclined-hole drilling jig primarily comprises a frame, at least one guide seat assembled thereon, and a workpiece positioner; wherein, the guide seats each have plural inclined guide channels to accommodate and orient a drill. The present invention is characterized by at least one first inclined guide channel and one second inclined guide channel of the guide seats with diverse inclinations, whereby, the guide seats can provide options for at least two diverse drilling inclinations to cater to users' various needs.

Abstract: An improved clamp structure includes a workbench, and the workbench has a quick release unit that can be turned linearly and a baffle board. A front clamping board and a rear clamping board are disposed between the quick release unit and the baffle board. An axial rod connects the front clamping board and quick release unit, and two guiding rods penetrate through the front and rear clamping boards to assist the sliding of the front and rear clamping boards. A link rod module is installed separately on the left and right walls of the front and rear clamping boards for controlling the quick release unit, such that when the axial rod drives the front clamping board to move, the front clamping board can be linked to the rear clamping board by the two link rod modules, so as to define corresponding quick opening and closing movements between the front and rear clamping boards.
