Abstract: A lock handle and rotating shaft combination mechanism includes a handle having a tubular socket extending axially. The socket includes a connection portion and a protrusion. A tubular rotating shaft includes a securing member formed radially to the rotating shaft. The securing member is located corresponding to the connection portion. A guiding slot is defined axially in the distal end of the rotating shaft. When the protrusion is engaged with the guiding slot, the rotating shaft expands radially outward, and the securing member is engaged with the connection portion to connect the handle to the rotating shaft. No tool is required during the assembling processes to reduce time for assembling the combination mechanism.

Abstract: An electric lock includes a housing, a manual control member rotatably affixed to the housing, and a clutch mechanism. The clutch mechanism includes a clutch base rotatably affixed to the housing; a retractable plug arranged on the clutch base, wherein the retractable plug is radially movable relative to the clutch base; a driving member abutting against a first end of the retractable plug; and a motor configured to drive the driving member to move relative to the clutch base toward the shaft of the manual control member.

Abstract: 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.

Abstract: A lock structure includes a case, a first latch, a second latch, a transmission member, a transmission module, a swaying plate and a driving plate, wherein the transmission module is rotated to drive the swaying plate and the transmission member to perform swing action for making the swaying plate driving the first latch being hidden into the case. In addition, the driving plate moves upwardly by swing action of the transmission member, and the driving plate drives the second latch in operation for making the second latch being hidden into the case.

Abstract: An input authentication method includes a processing unit generating a lead code according to a predetermined character string, wherein the predetermined character string includes a plurality of randomly arranged characters, the lead code is composed of N characters selected from the predetermined character string, and N is a positive integer; displaying the lead code on an input interface; the input interface receiving a first input; and when the first input corresponds to the N characters of the lead code, the processing unit performing a predetermined operation.

Abstract: A method for inspecting a lock set is to utilize a reception unit for receiving the signals from a lock set mounted at a door to inspect whether the door is closed and whether the lock set is locked or being broken.

Abstract: A handle apparatus comprises a case, a first positioning base, a second positioning base, a handle and a return mechanism. The return mechanism is engaged with the handle. The first positioning base and the second positioning base are disposed at the case. A positioning plate of the return mechanism optionally engages with the first positioning base or the second positioning base for making the handle apparatus optionally disposed at a left-hand swing door or a right-hand swing door.

Abstract: A rotation assembly includes a sleeve, a catch and an elastic member, the sleeve comprises a central longitudinal axis, a ring wall, a first through hole and a constraining slot having a planar surface. The central longitudinal axis is surrounded by the ring wall, and the first through hole and the constraining slot are formed at the ring wall. The elastic member comprises a free end and a limiting end, the free end is engaged with the catch, and the limiting end is limited by the constraining slot to prevent the elastic member from separating from the sleeve while the rotation assembly is impact by an external force.
