The locking plate comprises a main plate body, the two ends of the main plate body are both internallyprovided with a pair of multi-angle screw holes, locking plate connecting holes are formed in the left and right ends of the main plate body, sterilizing medicinal cotton is fixedly arranged at the lower end of the main plate body, and detachable locking plate fixators are arranged at the left and right ends of the outer wall of the sterilizing medicinal cotton respectively. Each detachable locking plate fixator comprises a small fixing instrument, a rotating disc, a small detacher, fixing belts, magnet adsorbers and small rotating shafts. The rotating discs are rotatably connected with the lower ends of the corresponding small fixing instruments, the small detachers are disposed at the lower end of the corresponding rotating discs, and the small rotating shafts are fixedly connected withthe lower ends of the corresponding small detachers. According to the locking plate for fixing the metatarsophalangeal joints for joint revision, fixing operation can be conducted on the locking plate, so that the locking plate is more stably, and the recovery of the toes is facilitated. At the same time, through arrangement of the sterilizing medicinal cotton, disinfection and sterilization canbe automatically carried out on a fixing portion, and infection is prevented.
