ABSTRACT:
A spring clamp includes a first and a second handle; a substantially L-shaped release link having an inner section transversely mounted in the first handle and an outer section located outside the first handle, and being pivotally turnably about a supporting point mounted in the first handle between the inner and the outer section of the release link; and a shaft having a front end fixedly connected to a movable jaw extended from a distal end of the second handle and a rear end obliquely extended through a hole on the inner section of the release link. To release the two handles of the spring clamp from an immovable position when clamping two workpieces together, a user needs only to downward push the outward projected outer section of the release link using one finger.
