Abstract:

Gardening shears may have a folding handle and handle extension connected by a pivot, with a projecting pin on one of the handle or extension which is received into two pin receiving channels on the other of the handle extension or handle. The handle extension nests into the handle when not in open position. The pin is located at a distance from the pivot. When the pivot is rotated, the pin enters the first channel, which is parallel to the direction of rotation of the pivot. The pivot may then slide in an elongated pivot channel, causing the pin to depart the first receiving channel and lock into the second receiving channel. The distance between the pivot and the pin and channels provides a greater lever arm to absorb torque, and the combination of two pin receiving channels allows the device to more securely lock into place.
