Abstract
The invention provides gripping pliers with a tongue back elastic traction device. The gripping pliers comprise a right arm, a left arm and a rotating shaft. When the gripping pliers are in a closed state, a connecting convex step of a tongue back connecting structure can be accommodated in a cavity formed by a right working groove and a left working groove. A right rotation limiting convex step and a left locking limiting convex step are inlaid in a transverse connection groove of the tongue back connecting mechanism; the right rotation limiting convex step and a left rotation limiting convex step can be inlaid in a longitudinal connection groove of the tongue back connecting mechanism; and a connecting nut of the connecting convex step of the tongue back connecting mechanism of the tongue back elastic traction device can be conveniently screwed on a connecting screw of a supporting body of the tongue back connecting mechanism. The gripping pliers can be stopped from being opened when in faulty operation by a self-locking mechanism of the gripping pliers, and the connecting convex step is prevented from being separated from the gripping pliers accidentally.
