The invention relates to a mechanical device for manually clamping objects (10), which allows a user to clamp objects which, owing to their characteristics, uses or processes, would be dangerous to the user's hand, as well as simply to clamp different objects. The device consists of five main parts: an upper jaw (15), a lower jaw (25), an upper handle (45), a lower handle (30), and a simple lever two-point shaft (65). In order to clamp an object with the device, the user inserts his/her thumb into the thumb hole (35) in the lower handle (30) and the rest of the fingers into the upper handle (45) in the space between the handgrip (50) and the finger-adjustment rod assembly (60). By expanding the fingers of the hand the upper (15) and lower (25) jaws open and by contracting the fingers the jaws close. Objects are clamped in an extension of the forearm, on the side opposite the palm of the hand. This device (10) can be used ambidextrously by making a simple change to the assembly of the lower handle (30). |
