The invention discloses an automatic spin lock device which comprises a lock head and a lock body. The lock head is connected with the lock body through a threaded connection structure, and one end ofthe lock head penetrates through the lock body and then is connected with a power mechanism. The lock head of the size can extend into an inner cavity of a corner fitting and can be clamped and fixedin an inner cavity of the corner fitting after being driven by the power mechanism to rotate by a preset angle. The threaded connection structure comprises a nut arranged on the lock body and a thread arranged on the outer surface of the lock head. The lock head penetrates through the lock body and then is connected with the nut in a threaded mode. The end, penetrating through the nut, of the lock head is connected with the power mechanism. The automatic spin lock device is ingenious in structural design, capable of being automatically locked with and separated from the corner fitting and wide in application range.
