Abstract

The invention provides a padlock. The padlock comprises a locking portion and is characterized in that the locking portion comprises a cylindrical rotary column and a transmission rod fixedly connected with the rotary column, the rotary column is adjacent to the middles/middle of a long blind hole and/or a short blind hole, a motor is adjacent to the middle of the long blind hole or the short blind hole, the motor and the rotary column are located on two sides of the long blind hole and the short blind hole respectively, unlocking recesses are formed in the positions, corresponding to a long lock rod and/or short lock rod, of the rotary column, matching recesses are formed in one sides, facing the rotary column, of the long lock rod and/or the short lock rod, a shifting portion is fixed at the output end of the motor and used for shifting the transmission rod to allow the rotary column to rotate, and a torsional spring for keeping protruding portions, opposite to the unlocking recesses, of the rotary column being accommodated in the matching recesses is arranged between the rotary column and a lock body. When the protruding portions are accommodated in the matching recesses, the locking portion locks a lock beam; when the unlocking recesses face the matching recesses, the locking portion unlocks the lock beam, and the transmission rod is tangential to the rotation trajectory of the edge of the shifting portion when the unlocking recesses face the matching recesses.
