发明名称 Wrench structure having a strengthened handle
摘要 A wrench structure includes a wrench body having a handle portion. The handle portion is formed with a reinforcement portion having a first side formed with a first holding portion and a second side formed with a second holding portion. The first holding portion has a plane vertical to that of the second holding portion. Thus, the user's hand and the holding portion of the wrench body have a larger contact area, so that the holding portion of the wrench body can apply a larger force and torque to drive and rotate the workpiece, such as the nut or the like.
