Referring to fig. 4, the avoiding notch is located on a surface of the lower end of the long locking arm, which faces away from the short locking arm.
The method for grooving the lock beam of the padlock disclosed in the Chinese patent publication No. CN101858172A comprises the following steps:
the first step is as follows: adjusting the hopper according to the model of the lock beam to be grooved;
the second step is that: selecting a cutter according to the specification and the model of the grooving;
the third step: putting the lock beam to be grooved into the adjusted hopper;
the fourth step: starting a motor, wherein the motor drives a ratchet wheel and a turbine to rotate through a driving shaft;
the fifth step: under a normal working state, the ratchet wheel rotates to enable the pawl to be intermittently shifted around the reset shaft, and the pawl shifts the lock beam to be cut in the hopper to the discharge hole;
and a sixth step: the worm is driven by the rotation of the turbine to rotate along the direction vertical to the driving shaft, so that the cam is driven to rotate, the reciprocating motion of the cam drives the swinging rod to swing back and forth around the swinging shaft, the tension spring always keeps the swinging section to be pulled to one side where the spring pull rod is located, the swinging rod swings back and forth and drives the ejector rod mechanism to slide along the slide way through the matching of the waist-shaped sliding chute and the sliding rod, the lock beam to be subjected to groove cutting in the hopper is ejected to the locking device through the ejector rod, and one end of the lock beam to be subjected to groove cutting is;
