The invention relates to an electric high-speed 
impact type anti-theft 
label which comprises a housing, an anti-theft bolt and a 
locking mechanism, wherein the housing consists of an upper cover and a base, the 
locking mechanism comprises a locking ball, a locking ball fixing seat, a locking ball cap and an elastic piece, the housing is internally provided with a rotating impacting mechanism and a sliding surface downwards pushing the locking ball fixing seat when the 
locking mechanism rotates, the rotating impacting mechanism comprises a rotating body, a magnetic block and an 
impact block, the magnetic block is arranged at the bottom of the rotating body, and the 
impact block is arranged on the rotating body and is positioned at the position of impacting the locking mechanism in the state of high-speed rotation. The invention has the 
advantage that the impact block in the rotating impacting mechanism produces a movable track different from a static or 
slow rotation state, thereby impacting the locking mechanism in the anti-theft 
label for unlocking. The anti-theft 
label is unlocked by needing a special tool, which effectively avoids the possibility of dismounting the anti-theft label artificially; meanwhile, the anti-theft label can automatically restore the locking state while leaving an unlocker, and has convenient use.
