The Fermat door knife is a key component in the elevator door system, performing the following functions:

Synchronizes the opening and closing of the elevator doors: After the elevator stops at a landing, the door knife mounted on the car door interacts with the roller of the landing door lock. Upon receiving the door-opening signal from the control cabinet, the door knife clamps or pushes the roller, locking the car door and landing door together. When closing the door, the door knife drives the landing door to close simultaneously, achieving synchronized movement of the car and landing doors.

Ensures the safe closing of the elevator doors: The door knife works in conjunction with the door lock. During the door closing process, the elevator can only operate normally after the door knife has accurately reset and locked the landing door lock. This prevents accidents caused by the elevator door not fully closing and causing movement.

Adapts to different elevator door systems: The Fermat door knife has a rational design and a wide range of applications. It can be used with different elevator models and landing door sills, demonstrating its versatility and compatibility.
