HANDLE MECHANISM

摘要

A handle mechanism used for driving a lock module in operation includes a handle, a linking member and a transmission rod, wherein the linking member is selectively engaged with the handle and the transmission rod. The handle is unable to drive the lock module in operation by the transmission rod driving and prevents the lock module from damage once an excessive force is applied to the handle when the linking member is not engaged with the handle and the transmission rod. Oppositely, the handle is able to drive the lock module in operation by the transmission rod driving when the linking member is engaged with the handle and the transmission rod.

1. A handle mechanism includes:
a case; a handle comprising a holding portion and a shafting portion, wherein the shafting portion is pivotally connected to the case; a transmission rod used for driving a lock module in operation; and a linking member selectively engaged with the shafting portion of the handle and the transmission rod, wherein the handle is able to drive the transmission rod in rotation by the linking member that is engaged with the shafting portion and the transmission rod and makes the transmission rod driving the lock module in operation when the handle is made available to drive the lock module in operation, and the handle is unable to drive the transmission rod in rotation by the linking member that is departed from the transmission rod and makes the transmission rod unable to drive the lock module in operation when the handle is made unavailable to drive the lock module in operation.
