Embodiment
[0014] Such as figure 1 As shown, the main body includes a dual force arm 6, a pure steel notch 1 and a handle 5. The two sets of force arms of the double force arm are connected in a rhombus shape, and one group of force arms of the double force arm are arranged crosswise with the pure steel notch. The other set of force arms of the arm is crossed with the handle. The connection points between the double force arms and the intersection points between the double force arms and the notch and the handle are all connected by bearings 2, and a spring 3 is arranged between the connection points of the double force arms. ; The handle is set with a grooved insulating sheath 4, and the handle is provided with a hanging ring 7.

The invention relates to a pair of strong mechanical wire scissors. A main body of the pair of strong mechanical wire scissors comprises double force arms, a scissor mouth and a handle. One set of the double force arms intersects with the scissor mouth; the other set of the double force arms intersect with the handle; and bearing connection is adopted for the connecting points between the double force arms, the intersecting points between the double force arms and the scissor mouth, and the intersecting points between the force arms and the handle. A spring is arranged between the connecting points of the double force arms. According to the pair of strong mechanical wire scissors, the aims of saving labor, improving the mechanical efficiency and prolonging the service life of the strong mechanical wire scissors are achieved.
Description
technical field [0001] The invention relates to a wire shear, in particular to a powerful mechanical wire shear, which is mainly used in electric power construction, inspection and trimming for cutting large wires or steel wires. Background technique [0002] Wire breaker is a tool that is widely used in electric power construction, checking and trimming broken wires. At present, the wire cutters and wire cutters used in electric power production sites can only cut thin metal wires with a small force, or they can cut thick wires but are heavy and inconvenient to use and carry. When it comes to large-diameter wires, especially for high-altitude operations, only the ground personnel cooperate to pass the broken wire cutter to the high-altitude operators through ropes, which will undoubtedly bring troubles to the operators and increase the number of operators, and at the same time bring more high-altitude workers. Hazard rate of falling object injury. It is time-consuming, la...
