WIPO Patent Application WO/2016/165490
Kind Code:
A1
Abstract:
An adjustable wrench comprising a wrench body and a worm gear (24). The wrench body comprises a handle (1) and a working part (2). The working part comprises a fixed part (22), a movable part (21), and a slide groove (20). The lower extremity of the movable part is arranged in the slide groove. A gear part (23) is provided at the edge of the lower extremity of the movable part. The working part also comprises a through hole (29). The worm gear is arranged within the through hole and meshes the gear part. When the worm gear rotates, the worm gear acts on the gear part and thereby driving the movable part to move either towards or away from the fixed part. A screw thread (26) of the worm gear is provided with at least two spiral lines. The adjustable wrench allows rapid adjustment of the space between the movable part and the fixed part and increases the torque that the worm gear can withstand.
