Unhooking synchronizer for double-hanging hook

The utility model discloses an unhooking synchronizing device for a double-hanging hook. Sliding blocks of the two crank sliding block mechanisms are connected through a synchronizing mechanism. Left-right movement of the synchronous connecting rod enables the first synchronous shaft and the second synchronous shaft hinged to the two ends to rotate in opposite directions; therefore, the connectingrods hinged to the other ends of the same sides of the first synchronizing shaft and the second synchronizing shaft synchronously and reversely move; driving devices positioned on the cranks of the two slider-crank mechanisms drive the cranks to rotate; when the movement speed of one crank is greater than that of the other crank; when the movement speed of one sliding block is greater than the speed of the other sliding block; the two sliding blocks are linked through the synchronizing device, so that the two crank sliding blocks move synchronously, the rotating speed of the driving device isthe same, the rotating mo
