Abstract: A multi-functional pliers has a body with a first fixed arm with a gripping portion. A second arm is connected with a first end to the body and has a gripping portion remote from the first end. The body has a pivot pin and the first end of the second arm is pivotably connected to the pivot pin. A blade is moveably mounted in the body. A toggle mechanism for transforming a rotary movement of the second arm into a translatory movement of the blade is provided. A returning part is connected to the body and a die member is connected thereto. The blade has a tool connected to one end thereof facing the die member. The first and second arms in a rest position of the pliers are positioned adjacent to one another such that the first and second arms can be gripped with one hand by a user, wherein by squeezing the fingers of the hand the second arm is moved toward the first arm. The toggle mechanism includes a control rod. The blade has an articulation pin to which the control rod is pivotably connected.

Abstract: Cutting pliers for plastic material sections, rubber-like joints and similar, including two levers (6, 7) articulated to each other on an axis (8) and kept spread apart by a spring (9), characterized in that one of the levers (6) supports an anvil (11) while the other lever (7) is provided with a blade-carrier (16) on which a blade is fixed in a removable manner.

Abstract: The necking pliers comprises a first arm having a U-shaped cross section and forming a nose in which is made a notch, with the notch defining blade-forming edges. The first arm is articulated to a second arm via a first pin placed near one end of the nose. The second arm defines a set of ramps for actuating at least one blade articulated on a second pin of the first arm, with the second pin being placed beyond the notch.

Abstract: The plug grip comprises a first and a second arms pivotally mounted together, with the first arm leading to a bearing shoe member and the second arm causing a raise of a screw of an expansion plug. The second arm comprises two successive bearing points, a first bearing point providing a great lever arm ratio for causing a start of bending of the expansion plug and a second bearing point providing a smaller lever arms ratio for increasing a distortion stroke of the expansion plug.

Abstract: Pliers for positioning clips which form connecting rings between a wire netting and support wires. The pliers comprise two arms pivotally connected together, with the front ends of these two arms causing displacement of two small rods articulated on a same pin which is rigid with a mobile part guided between two plates which form a body for the pliers and carry at a rear portion the pivot axis of the arms. The plates are spaced apart at the front end by a fixed part of substantially the same thickness as that of the mobile part, and each plate comprises an upper portion with an opening which, in cooperation with a clip supply magazine mounted perpendicularly to the plates, enables introduction of a clip behind the mobile part and deformation of the clip between the mobile part and the fixed part so as to surround the support wire and a wire forming the netting. Displacement of the pin which drives the mobile part is limited by openings provided in the plates which form the pliers body.
