Abstract
An adjustable spanner having a releasable engagement securing mechanism is provided. The spanner comprises a spanner handle, a first holding portion, a second holding portion, a third holding portion, an adjustment member, a push rod, and at least one resilient element. Each of the first, second, and third holding portions defines respective contact surfaces. The first holding portion is fixedly coupled to one end of the spanner handle, while the second holding portion is displaceably coupled to the spanner handle. The third holding portion is displaceably coupled at the given end of the spanner handle. An adjustable U-shaped region is collectively formed by the three contact surfaces. A push rod disposed in displaceable manner within the spanner handle is coupled to the third holding portion for actuating the displacement thereof between a clamping position and a releasing position. The push rod is provided with an actuation button by which it may be displaced relative to the spanner handle.
