Abstract: A tool comprises an underbody wall structure having two side walls and a material feeding surface held by the two side walls; and a latch mechanism coupled to the underbody wall structure. The latch mechanism comprises two rotation brackets attached onto the two side walls, defining two through bores thereon, respectively; two rotatable plates rotatably attached and mechanically engaged to the two rotation brackets via two bolts, respectively, so that the two rotatable plates are operably rotatable around the bolts relative to the two rotation brackets; and a latch member having two free ends engaged respectively to the two rotatable plates via the through bores of the two rotation brackets and the two side walls.

Abstract: A tool comprises an underbody wall structure having an internal wall and two side walls attached to two ends of the internal wall; and a dual-latch mechanism coupled to the underbody wall structure. The dual-latch mechanism comprises a first latch configured to moveably couple to the underbody wall structure via a first brace affixed to the internal wall; a second latch configured to moveably couple to the underbody wall structure on a side opposite of the first latch, via a second brace affixed to the internal wall; and an integral connection translationally moveable with respect to the underbody wall structure and integrally connecting the first latch to the second latch, wherein moving the first latch in a first direction causes the second latch to move in the first direction. The first latch, the second latch and the integral connection are a monolithic part.
