Abstract

본 발명은 복스 렌치에 관한 것으로, 렌치 암(100)의 계 및 반시계 방향의 회전을 모두 나사의 잠김 및 풀림 작업을 할 수 있게 한 양 방향 회전 전달용 복스 렌치에 관한 것이다. 종래의 복스 렌치는 나사의 잠김 및 풀림 작업시 암(100)의 회전 방향이 나사의 잠김 및 풀림 방향과 동일 방향으로 작용할 때에는 암(100)의 회전력은 유효일을 하지만, 암(100)의 회전방향과 나사의 잠김 및 풀림 방향이 역 방향일 때에는 암(100)과 축(20)은 공회전을 하므로 무효일을 하게 되고, 작업자의 노동력의 낭비와 작업 시간의 지체로 작업 능률을 저하시켯다. 따라서 본 발명은 렌치의 몸체(10) 내부 하측벽에 내접 기어(30)를 형성하여 상기 내접기어(30)와 물림을 형성하는 중간 기어(40) 및 종동기어(50)를 구성하여 상기 종동 기어(50)를 항상 암(100)의 회전과 역 방향으로 동작하게 구성한 것과, 축 머리부와 축 몸통부(24)의 상·하에 래치기어를 형성하고 상기 래치기어와 대응되는 폴을 구성한 것으로 렌치 암(100)의 회전과 나사의 잠김 및 풀림방향이 역 방향일 때에도 암(100)의 회전력을 축(20)에 전달하여 나사의 잠김 및 풀림 작업을 수행할 수 있게 한 것으로, 불 필요한 힘의 낭비를 줄이고 나사의 잠김 또는 풀림 작업의 능률을 향상되게 하는 것임.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box wrench, and more particularly, to a box wrench for bidirectional rotation transmission that enables both locking and releasing of a screw in a system and counterclockwise rotation of the wrench arm 100. Conventional vox wrench has a rotational force of the arm 100 is effective when the rotational direction of the arm 100 acts in the same direction as the locking and unlocking direction of the screw during the locking and unlocking operation of the screw, but the rotational direction of the arm 100 When the screw locking and disengaging direction is reverse, the arm 100 and the shaft 20 are idling and thus become invalid, and the work efficiency is reduced due to waste of labor and delay of working time. Therefore, the present invention forms an internal gear 30 in the lower wall of the body 10 of the wrench to form the intermediate gear 40 and the driven gear 50 to form a bite with the internal gear 30 to the driven gear The 50 is always configured to operate in the reverse direction of the rotation of the arm 100, and a latch gear is formed above and below the shaft head and the shaft body 24, and a pole corresponding to the latch gear is formed. Even when the rotation of the arm 100 and the locking and releasing direction of the screw are reverse, the rotational force of the arm 100 is transmitted to the shaft 20 so that the locking and releasing of the screw can be performed. To reduce waste and improve the efficiency of screw locking or loosening.
