The invention relates to a pair of pressure arm type bolt clippers comprising a bolt clipper body. A first clamp arm of the bolt clipper body is fixedly connected with an operation rod through a fixing buckle I. The rear part of the operation rod is equipped with an installation seat. A pressure arm rod is hinged to the installation seat. The pressure arm rod is connected with two connection rods III, and the other ends of the two connection rods III are connected and form a connection point. A second clamp arm of the bolt clipper body is fixedly connected with one end of a connection rod I through a fixing buckle II. The other end of the connection rod I is hinged to one end of a connection rod II. The other end of the connection rod II is connected to the connection point. Compared with the prior art in which a conductor is cut off with the aid of an insulated bucket arm vehicle, a conductor can be cut off through ground-potential operation, the pressure arm rod can increase the force under operation of the main operation rod to reduce the shear resistance, and a conductor can be easily cut off at the first attempt.
