The invention discloses a telescopic locking device for a safety belt, a safety belt system and a vehicle, the locking device comprises a lock head, a traction piece and a winding mechanism, the winding mechanism comprises a rotating shaft and a spiral guide piece arranged on the outer side of the rotating shaft, one end of the traction piece is connected with the lock head, and the other end of the traction piece is connected with the spiral guide piece. The other end of the traction piece is fixedly connected with the rotating shaft, and the rotating shaft is used for rotating to drive the traction piece to move along the spiral guide piece. The locking device can stretch out and draw back automatically, the lock head of the locking device is arranged on the front portion of the cushion, and the lock head is more flexible. The second locking matching piece is connected with the locking device, and the safety belt can be changed into a four-point type from a common three-point type, so that the safety restraint effect of preventing the hip from moving forwards in the dynamic collision and lying posture position is achieved.
