Summary:Wrench capable of avoiding detachment of a screw-thread member. The wrench is used to fit onto a polygonal screw-thread member, including: a handle section; a head section disposed at one end of the handle section and formed with a polygonal fitting hole; at least one channel formed on the inner circumference of the fitting hole along the axis of the fitting hole; and at least one slide member up and down movably disposed in the channel and partially protruding into the fitting hole, the sliding travel of the slide member having an upper and a lower dead ends. The wrench can be fitted onto the screw-thread member from both ends of the fitting hole and the slide member can be pushed by the screw-thread member and moved to any of the dead ends and stopped thereby. The screw-thread member is stopped by the slide member from slipping out of the wrench.
