Bolt with anti-rotation function

The utility model relates to a bolt with an anti-rotation function. Screw and head, external threads are arranged on the periphery of the screw rod; the head part is fixedly arranged at one axial endof the screw rod; a locking rail and a driving rail are arranged in the screw rod; the track direction of the locking track is the radial direction of the screw rod, and the track direction of the driving track is coaxial with the screw rod; the locking rail penetrates through the screw outwards in the radial direction of the screw and communicates with the driving rail inwards, a locking block isarranged in the locking rail in a sliding mode, a driving push rod for pushing the locking block outwards in the radial direction of the screw is arranged in the driving rail in a sliding mode, and adriving end is arranged at the position, penetrating through the head, of the driving push rod. By the adoption of the scheme, the bolt with the anti-rotation function pushes the locking block to protrude outwards by driving t
