Definitions

  • This invention refers to a movable head, which in combination with a fixed head and a guide, makes up a vise or handscrew able to clamp one object to another.
  • a vise of this type is shown, for example, in the Spanish utility model with application number U9900362, or in the utility model with application number U200202066.
  • the figures described show how the body of the head (1) incorporates a transverse orifice (2) in correspondence with one of its ends.
  • This orifice serves to allow said body or movable head (1) to move along a guide not shown in the drawings, whose cross section coincides in shape and dimensions with that of the orifice (2).
  • the head (1) is locked onto this guide because of the head's tendency to tilt laterally when its pressure element (3) is acted on, locking that may be favored by the existence of a brake (4) on the head (1), next to the orifice (2).
  • the brake (4) is equipped with a toothed front that acts on the edge of the guide. In any case, the pressure element (3) can move parallel to said guide when a manual lever (5) is acted on, all in a conventional manner.
  • a second orifice parallel to the first one formed by two coaxial sections.
  • One section (6) the one closest to the pressure element (3), has a smooth surface, and the other (7) has an inner thread on which a shaft moves.
  • the shaft has two sections: a section (8) opposing the pressure element (3), which screws onto the aforementioned section (7) of the orifice on the body (1), and a second section (9), whose diameter is considerably smaller and whose thread direction is the opposite of the one on section (8), which in turn screws into a bushing (10).
  • This bushing has a threaded inner surface in correspondence with section (9), and its outer surface slides on the unthreaded section (6) of the aforementioned orifice, while its free end receives the aforementioned pressure element (3) by means of a rivet or any other means.
  • Said bushing (10) can only move axially in its housing as it is related to the body (1) of the movable head with the collaboration of a pin or similar device (11).
