Abstract
The hand tool comprises two members, for example male and female blade members in the case of a garden pruner, each formed with a tang portion which extends within a handle. For locking the members in a closed position a catch pin unit is fitted to one of the handles; the unit comprises a catch button secured slidably to a mounting plate by engagement with a spring plate on the opposite side of the mounting plate. The spring plate has resilient fingers which hold the spring plate releasably in selected positions. A catch pin which engages in the catch button is movable thereby along a slot in the associated member into and out of a recess in the other member to lock or release the members. The members are releasably secured to the handles by a pivot bolt which passes through registering apertures in each member and associated handle. A recess in a said tang portion forms a seating for a stop cushion which extends to the surface of the handle through an opening in the handle above the recess.
