The invention discloses a signal control electric hook lock which comprises a lock frame, a minitype gear motor, an inductive switch, a clamping mechanism for closing a door, a cover plate for covering the lock frame and a lock sleeve for limiting the position of the clamping mechanism during locking. The signal control electric hook lock is characterized in that the lock frame is internally provided with a screw rod and a shaft; the clamping mechanism is fixed by virtue of the shaft and can rotate around the shaft; the screw rod is provided with a driving mechanism matched with the clamping mechanism; the screw rod is connected with a rotating shaft of the minitype gear motor; the minitype gear motor is connected with the inductive switch; the cover plate is internally provided with two limiting devices; the cover plate is arranged on the lock frame; the limiting devices are used for inducing the movement position of the driving mechanism. According to the signal control electric hook lock, a traditional lock structure which is unlocked by a key is abandoned, the signal control electric hook lock can be unlocked directly by virtue of fingerprints, sounds or communication signals, is good in anti-theft performance and has a structure which can be emergently unlocked without a key.
