Abstract: A vise includes a base having a fixed clamp member and a rack member is connected to the base. A movable clamp member is movably connected to the base and a rod extends through a horizontal portion of the movable clamp member. A connection member is mounted to the rod and has two lugs between which a pushing member is pivotally connected. A position member is pivotally connected to the connection member and a second end of the position member is engaged with of the rack member. A head is connected to the rod and located between the two lugs. The head has an inclined surface and an underside of the pushing member is rested on the inclined surface. A pushing surface is defined in an end of the pushing member and is matched with a vertical portion of the movable clamp member. The pushing member prevents the top portion of the movable clamp member from being deformed.

Abstract: Herein provided is a vise of the type, in which a movable clamping jaw is made slidable on a base having a stationary clamping jaw at its one end toward and away from the stationary jaw and is connected to the base by means of a connecting member. The base is formed at its widthwise center with a longitudinal groove, which extends in the longitudinal direction through the upper and lower sides thereof, and in its lower side with a number of transverse grooves which extend at the both sides of the longitudinal groove. The movable clamping jaw is formed with a recess which is wider than the longitudinal groove of the base and which has its bottom extending in parallel with the upper side of the base and formed with a through hole. The connecting member is received in the recess such that it can move in the longitudinal direction of the longitudinal groove.

Abstract: This invention relates to a vice, particularly a parallel vice, having a displaceable jaw and at least one fixed jaw, clamping of said displaceable jaw against the fixed jaw being effected by means of a spindle inclined relatively to the displacing direction of the displaceable jaw, and anchoring means of said spindle being rapidly disengageable, shiftable and reengageable with the bed of the vice.
