Strength reinforcing structure of a lock outer handle

摘要

A strength reinforcing structure of a lock outer handle includes a disk seat defining a first hole rotatably receiving a handle and a drive shaft tube. The handle has a drive plate rotated by a lock core to drive a lock snapping plate to move longitudinally. The drive shaft tube has one end secured in the handle, and the other end provided with locking grooves for securing locking blocks of a driven ring which is combined with a drive tube which is combined with a restoring member which defines fitting slots combined on the drive shaft tube. The drive tube passes through a positioning plate which defines a second hole provided with locking edges engaged or disengaged with end edges of the lock snapping plate.
