A lock that can be locked from two sides thereof includes a first fixing base combined with a seat plate at one side of the door plate for receiving a securing plate and a restoring spring seat. The restoring spring seat defines a drive hole combined with a drive tube. A first drive shaft tube has one end combined with the restoring spring seat. The first drive shaft tube defines a slot such that a locking plate protrudes from and retract into the slot. A first handle is combined with the other end of the first drive shaft tube. The first handle has a lock whose lock core defines a double sector faced slot into which one end of the first lock control plate is inserted. The other side of the door plate is combined with a second fixing base and a seat plate. The second fixing base defines a shaft hole for passage of a second drive shaft tube. The second drive shaft tube receives a locking cylinder, an elastic member, a cone-shaped plate, and a connecting cylinder, and is combined with a restoring spring seat. The locking cylinder has locking plates that can be locked in the locking grooves or detached from the locking grooves by pressing of the elastic member. The locking cylinder has a bottom defining arc-shaped slots. The cone-shaped plate has cone-shaped wings protruded from the arc-shaped slots or rested on the bottom of the locking cylinder during rotation of the cone-shaped plate.
