Inward opening handwheel manufacturers tell you that the main function of the lock cylinder is to transmit torque from the head, thereby driving other parts of the lock to unlock and lock. Padlocks, drawer locks, door locks and bicycle locks have different lock cylinder head structures and different ways of transmitting torque, but the functions are the same.

Inward opening handwheel manufacturers tell you that the lock cylinder adopts a number of anti-theft technologies, a variety of special-shaped anti-pulling pins, to prevent technical opening, and with the unique design of the pin and blade structure, it has high safety performance against technical opening. The manufacturer of the Inward opening handwheel tells you that the lock cylinder is equipped with precise numbered marbles and special-shaped marbles. When the technical opening is performed, the numbered marbles and the special-shaped marbles must be pulled at the same time, and they will be automatically locked, so that the technical opening will fail.
Inward opening handwheel manufacturers tell you that the lock cylinder adopts multiple combinations of various special-shaped marbles, and can program up to billions of key numbers, so as to achieve zero mutual opening in the area (one in 16 million). The lock cylinder is equipped with a lateral internal pressure side post bayonet device, which greatly improves the ability to prevent violent twisting.
