Abstract
A spring clamp includes a first body which comprises a gripping portion and a clamping portion, a second body which comprises a gripping portion and a clamping portion, a first pivot element which pivotally connects the first body and the second body, and a locking mechanism which comprises at least a pair of friction pair components. The first friction pair component is arranged on the first body, and includes a first friction pair element; and the second friction pair component is arranged on the second body, and includes a second friction pair element. The first and second friction pair elements rub against each other to effect the locking function. The rubbing of the friction pair elements occurs mainly in the plane perpendicular to the first pivot element axis.
