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.

Clamping and or spreading tool

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.

Incremental gear for bar clamp

The assembly method of the invention uses a cartridge that is separate from the housing of the device being manufactured. The cartridge is configured such that the location of the various components is defined and the components are easily accessed. The cartridge and its components may be assembled off of the main assembly line. Once the cartridge is assembled, the cartridge and assembled components can be placed in the housing. The assembly of the device can then be completed.

Assembly method and apparatus

A clamping and/or spreading tool comprising a push or pull rod to which a mobile jaw is fixed, a fixed jaw, a gear mechanism which can be used to move the mobile jaw towards or away from the fixed jaw by moving the push or pull rod in a clamping or spreading direction, and to apply clamping and/or bracing forces between the jaws, and a lock used to block movement of the push or pull rod in an opening direction opposing the clamping or spreading direction, in order to maintain clamping and/or spreading forces produced between the jaws. A mechanism for dissipating the stored clamping and/or spreading forces enables an absorption movement of the push or pull rod in the opening direction along a pre-determined absorption course, and especially detachably blocks an absorption movement of the push or pull rod over the predetermined absorption course, in the opening direction.

Release explosion damper

A clamping and/or spreading tool including a push or pull rod, comprises at least one lock blocking displacement of the push or pull contrary to the clamping and/or spreading direction by it being canted by at least one biasing mechanism, such as a spring, relative to the push or pull rod, and a releasing mechanism which when actuated cancels the blocking effect of the lock such that the biasing mechanism and the releasing mechanism functionally engage the lock at least at opposite sides of the push or pull rod.
