Abstract:
An adjustable spanner comprising:(a) a handle having first and second end portions and an intermediate portion extending longitudinally therebetween, said handle having formed therein first and second assembling holes;(b) a first holding portion fixedly coupled to said first end portion of said handle, said first holding portion defining a first contact surface;(c) a second holding portion adjustably coupled to said first end portion of said handle, said second holding portion defining a second contact surface selectively displaced from said first contact surface;(d) a third holding portion coupled to said first end portion of said handle in displaceable manner between a clamping position and a releasing position, said third holding portion defining a third contact surface, said third contact surface being disposed in said clamping position adjacent at least one of said first and second contact surfaces to collectively defining with said first and second contact surfaces a substantially U-shaped engagement region, said third contact surface being disposed in said releasing position substantially offset from said first and second contact surfaces;(e) a push rod coupled to said third holding portion for actuating said displacement thereof between said clamping and releasing positions, said push rod having a first section disposed in displaceable manner within said second assembling hole of said handle and a second section extending longitudinally therefrom, said push rod including an actuation button protruding from said second section; and,(f) a first resilient element coupled to said first section of said push rod, said first resilient element biasing said push rod relative to said handle to thereby bias said third holding portion to said clamping position.
