Claim:
1. An electric lock for doors comprising: a housing having an opening on a side wall thereof for a latch to enter; a first catch arranged in a first portion of said housing, the first catch having a first inner arm and a first outer arm, the first outer arm arranged near said opening; a second catch arranged in a second portion of said housing correspondingly to said first catch, the second catch having a second inner arm and a second outer arm, an end of said second inner arm partially overlapping an end of said first inner arm to form an overlap, a hedge for locking the latch formed by said first and second outer arms; a driving device disposed inside said housing and near the first catch, the driving device having a driving stick to protrude and withdraw; and a blocking element displaceable between an opening position and a closing position by said driving stick; whereby the blocking element, when in the closing position, prevents rotation of the first catch toward an open position thereof, the first catch thereby preventing rotation of the second catch toward an open position thereof due to the arrangement of said overlap, the opening thereby placed in a locked status without the blocking element contacting the second catch; and whereby the blocking element, when in the opening position, allows rotation of the first catch toward the open position thereof, the first catch thereby allowing rotation of the second catch toward the open position thereof, the opening thereby placed in an unlocked status.
