  • Patent number: 10406656
    Abstract: A clamp, including a first clamp body and a second clamp body. The first clamp body includes a first clamp jaw and a first handle, movably connected to each other. The first clamp jaw is rotatably connected to the second clamp body at a first connecting position, and the first handle is rotatably connected to the second clamp body at a second connecting position. When the relative position of the first clamp jaw and the first handle is changed, a force occurs between the first clamp jaw and the first handle. A moment formed by the force with the first connecting position as a fulcrum is greater than a moment formed by the force with the second connecting position as a fulcrum.

When the cigar cutter (1) is squeezed, for example by the pressure of a single hand on the squeeze bar (6) and the side of the housing (2) opposite the squeeze bar (6), a mechanism translates the squeezing force into an irising movement of the blades (5). The mechanism includes rings (11), squeeze bar pins (15), and blade pins (21). The inside diameters of the rings (11) are less than that of the opening (3). Part of the end of the squeeze bar (6) protrudes into the housing (2) and is forked so as to sandwich the rings (11). Squeeze bar pins (15) extend from the rings (11) and pass through slots (17) in the forked end of the squeeze bar (6).
