Abstract
A double-safety trailer lock with an adjustable length comprises a lock bar and a lock body matched with the lock bar, wherein one end of the lock bar far from the lock body is a large-diameter end, an external thread is provided on the large-diameter end, an adjusting sleeve is arranged outside the large-diameter end, and an internal thread is provided on the inner wall of the adjusting sleeve, so that the adjusting sleeve can move axially along the large-diameter end by matching the internal thread with the external thread; through the axial movement of the adjusting sleeve relative to the lock bar, the effective length of the lock bar can be adjusted, and the effective length of the lock bar is basically the same as the required length between the actual family car and the trailer, so that the movement of the lock bar in the use process is minimized, and the connection of the trailer lock is more stable.
