Abstract
A hand operated gripping tool has a first handle (301), a first jaw (201) connected with the first handle, a second handle (302) pivotably connected with the first handle to permit relative pivoting movement of the second handle with respect to the first handle and a second jaw (202) connected with the second handle. One of the first jaw and second jaw is a removable jaw and the removable jaw is push-fit attachable to the respective handle.
Claims21
A hand operated gripping tool comprising:
- a first handle;
- a first jaw connected with said first handle;
- a second handle pivotably connected with said first handle to permit relative pivoting movement of said first and second handles;
- and
- a second jaw connected with said second handle,
- wherein one of said first jaw and second jaw is a removable jaw and said removable jaw is push-fit attachable to the respective said handle.

A hand operated gripping tool comprising:
- a first handle;
- a first jaw connected with said first handle;
- a second handle pivotably connected with said first handle to permit relative pivoting movement of said first and second handles;
- a second jaw connected with said second handle;
- a strut having first end pivotally attached to said second handle;
- a locking switch pivotally attached to said first handle;
- and
- a biasing member acting on said locking switch,
- wherein said locking switch has at least one tooth engageable with teeth provided on said strut, said biasing member biases said locking switch towards said strut so that said at least one tooth engages said strut and slides over said teeth on said strut when, in use, said first and second handles move towards one another.
