Abstract
A spring clamp has an elastically operable locating mechanism provided between two handles of the spring clamp, so that the two handles may instantaneously enter into a firmly braked position when the spring clamp clamps work pieces thereto, and immediately released from the braked position when a push button of the locating mechanism is pushed. The spring clamp with the elastically operable locating mechanism is more convenient for use without the risk of unexpectedly loosening from work pieces clamped thereto.
