Abstract
The invention relates to a clamping and/or spreading tool having a stationary jaw and a support to which the stationary jaw is fixedly connected. A push or pull rod is slideably supported on the support and a movable jaw is fixedly arranged on the push or pull rod, wherein the clamping and/or spreading tool is designed to displace the push or pull rod relative to the fixed jaw in an advance direction. The clamping and/or spreading tool further comprises at least one trigger with at least two lever configurations, wherein a mechanism for switching from a first lever configuration to a second lever configuration is provided. At least two active levers are engageable with the push or pull rod via at least one driver to displace the push or pull rod in an advance direction.
