There is a jack at the left end of the main rod mentioned. The left end of the main rod mentioned fits with a head. The head mentioned has an insertion rod fitting with the jack mentioned. Motion sleeve is arranged on the main rod mentioned. The motion sleeve mentioned has an inner bore. The inner bore mentioned runs through the motion sleeve mentioned. The main rod mentioned fits in the inner bore mentioned. Over three end parts are set up circlewise on the outer ring of the motion sleeve mentioned. Jack No.1 is set up at the end of the end part mentioned away from the motion sleeve mentioned. Stress application rod is arranged in the jack No.1 mentioned. This device uses a main rod as driving medium, completes the positioning of nut through head, drives the rotation of main head through the rotation of motion sleeve and finally completes the backout of nut. Main rod requires a small stress application space. Therefore, the scope of application of this device increases. Meanwhile, main rod can be inserted into a deep position, which is easy to remove nuts with a deep mounting position. Attached figure of de scriptions 4.) Fig.1 |
