Abstract
A clamping and/or spreading tool comprises a drive for displacement of a push or pull rod to which a movable jaw is fixed with respect to a support carrying a stationary jaw in longitudinal direction of the push and pull rod, said drive comprising a torsion spring and being adapted to enter torque transmitting engagement with the push or pull rod for displacement of the same.
Claims14
A clamping and/or spreading tool comprising a drive for displacement of a push or pull rod to which a movable jaw is fixed with respect to a support carrying a stationary jaw in a longitudinal direction of the push and pull rod, said drive comprising a torsion spring connected to the push or pull rod for displacement of the push or pull rod to move said movable jaw toward said stationary jaw, wherein the torsion spring comprises an unwound band section that is at least partly positioned in a seat or a groove of said push or pull rod between the support and the movable jaw and a wound band section positioned in said support and further including a handle on said support and a drive arm movable relative to said handle for moving the movable jaw toward said first jaw, said handle and said drive arm being operable by one hand.
A clamping and/or spreading tool comprising:
- a support supporting a first jaw;
- a rod supported in said support for relative movement relative to said support;
- a movable jaw supported on said rod;
- a spiral band spring for moving said rod to move said movable jaw toward said first jaw, said spring having a first end and a second end, said first end being wound and supported completely within said support and said second end being connected external of said support to said rod for moving said rod and further including a handle on said support and a drive arm movable relative to said handle for moving the movable jaw toward said first jaw, said handle and said drive arm being operable by one hand.
A clamping and/or spreading tool comprising:
- a support having a handle and supporting a first jaw;
- a rod having a length supported by said support for relative movement relative to said support;
- a movable jaw supported on said rod;
- a handle on said support and a drive arm movable relative to said handle for moving the movable jaw toward said first jaw, said handle and said drive arm being operable by one hand;
- a spiral band spring for moving said rod to move said movable jaw toward said first jaw, said spring having a end wound portion and a an unwound portion arranged such that said spring extends along the length of the rod between the support and the movable jaw, said wound portion being supported in said support and said unwound portion being connected to said rod external of said support for moving said rod.
