A long shackle padlock includes a cylindrical housing, a lock housing fitted in the cylindrical housing, a locking means protected in the lock housing, and a shackle. The locking means can move a first bead and a second bead with a coil spring interposed between, for locking and unlocking, with the second bead fitting in a bead hole of the foot of the shackle in locking, and with the first bead pushed and moved inward by the locking means to let the second bead move inward to disengage from the bead hole of the foot of the shackle in unlocking. The locking means and the lock housing can be applied to other kinds of locks such as common padlocks, U-shaped locks, wire locks, etc.
