摘要

The bolt has a control mechanism with a door-knob hole (13) acting on connecting rods under the action of a handle. The mechanism has a turret for activating a dead bolt. A transmission unit (34) connects the dead bolt with the rods to reflect back a control of the dead bolt on the rods. A driving unit connects the hole with the dead bolt to push back the dead bolt for locking the rods.
