Description

Adjustable powerful excising forceps

The utility model is a kind of hand-operated tools that metal wire rod cuts off that is used for.

The excising forceps that generally use in the industry are that cutter head and blade are an integral body according to the duplex arm excising forceps of second lever transmission principle design, adopt the more expensive Hardmetal materials of price, and knife-edge part is hinged with pressing plate, and are terminal hinged with the connection arm.This structural loads ability is less, uses effort, and the hard slightly or diameter of material can not cut off when big slightly, and blade is easy to wear to crumble and instrument integral body is scrapped reduce service life.

The purpose of this utility model is to provide a kind of job area big, rapid operation, the adjustable powerful excising forceps that the life-span is long.

The utility model adopts the adjustable powerful excising forceps of three grades of lever transmission principle structural designs, comprises cutter head, connection arm, pressing plate, pipe handle, it is characterized in that cutter head initial point bolted splice, inlays removable blade above, and hinged with the connection arm by connecting rod; Hinged platen can be by two-way bolt adjustable range on the connecting rod; The connection arm is hinged by centre bolt after being connected with the pipe arm.During operation, hold the pipe handle and divide right and left, left and right sides link arm rotates, each pin joint interlock, and blade opens, and is fashionable in the pipe handle, and less action force passes to the bigger shearing force of blade generation and cuts off metal material.

The utility model structural design reason, substantially can be more than the laborsaving twice under the situation that does not have to increase at volume, size, parts, blade can reconditioning be changed the service life that has prolonged instrument, the adjusting of cutting edge gap conveniently, safe and reliable, positioning stablity is widely used in the cut-out operation of various metal wire rods, building iron and cable.
