Abstract: A manual clamp tool contains a body, a slidable seat, a movable handle, and two clamping arms. The body includes an elongated casing, a fixer, and a drive platform. The elongated casing accommodates multiple retainers which are connected to form a clamper, and the drive platform has a limitation means and a notch. The slidable seat is limited by the limitation means to move linearly within a predetermined range. The movable handle includes a rotatable connection portion and a grip portion. A respective one clamping arm includes an actuation portion and an engaging portion. The actuation portion is connected with the slidable seat so that the movable handle actuates the slidable seat to drive the two clamping arms to push and clamp the multiple retainers on the drive platform forward, and the multiple retainers engage on a rope of a Venetian blind.

Abstract: A fastener driving tool includes a housing unit with a fastener striking opening, a striking member with an engaging slot, a locking member with a front engaging end detachably engaged to the engaging slot, and a handle unit pivoted on the housing unit. When the handle unit is pressed down to shift the driving tool from an initial to an energy-storing state, the locking member is driven to move the striking member away from the striking opening. When the handle unit is pressed down continuously to shift the driving tool from the energy-storing to a striking state, the front engaging end is driven to disengage from the engaging slot, and the striking member is driven to move down to the striking opening for performing a striking stroke.

Abstract: A fastener driving tool includes a magazine unit, a handle, a striking plate, an energy restoring member and a wire bending spring disposed to a housing unit. The housing unit includes an inner housing assembly made from a plastic material, and an outer housing assembly made from a metal material and covering the inner housing assembly. The wire bending spring is biased for storing a striking energy for the striking plate, and includes an extending section and a backwinding section. The extending section has first and second ends. The backwinding section is connected with the second end, and extends and bends toward the first end to terminate at a terminal end portion. The ratio of a height to a width ranges from 1:1 to 1:1.6.

Abstract: A spring energized fastening tool with compact, rigid, low friction working elements is disclosed. A torsion power spring includes forward extending arms with the arms pressing each other proximate a front distal end of the spring. A cantilevered lever links to a handle and engages the spring adjacent to the striker. A bottom loading staple track unlatches and opens through a simple pulling-out action. Structures are provided to enable fitment with a formed sheet metal handle and housing. The fastening tool is particularly simple to assemble, powerful, and of low operating effort.
