ABSTRACT:
A padlock having a latch with a large field angle comprises a housing combined by a pair of opposed casings, a latch disposed within the pair of opposed casings, a pushing block for driving the latch to rotate, and a number selecting device for controlling the pushing block to be shifted. When the number selecting device is selected to a correct number sequence, the pushing block is permitted to be pushed into the casings to drive the latch to pivotally retract within the housing. Thereby, the latch can be opened in a large field angle to facilitate the use of the padlock.
