Abstract

The invention discloses a shearing range adjustable ratchet type cable shears, and the cable shears comprise a fixed handle, a movable handle, a fixed knife rest, a movable knife rest, a bottom plate, a cover plate, a rack and a pawl; the fixed handle is fixedly connected to the surface of the bottom plate, the movable handle is rotatably connected with the bottom plate, and the unidirectional rotating rack is arranged at the rotating position of the movable handle; a cover plate is fixedly connected to the surface of the bottom plate, a fixed knife rest is fixedly connected to the end of the bottom plate, a movable knife rest is rotatably connected to the end of the fixed knife rest, a rotating pin is arranged at the joint of the fixed knife rest and the movable knife rest, and a detachably-connected blade is arranged in the movable knife rest. According to the invention, the surface of the movable knife rest is provided with the detachably connected blade, so that a blade with a shearing knife edge with a proper size can be conveniently replaced according to different diameters of cables, and compared with an integrated movable knife rest, the cable shearing range of the cable shears is greatly expanded, and the use universality is improved.

Description

technical field [0001] The invention relates to the technical field of cable cutting tools, in particular to a ratchet type cable cutter with an adjustable cutting range. Background technique [0002] The cable cutter is a kind of pliers specially used for cutting cables, with two staggered blades that can be opened and closed. Cable scissors are large scissors, which are designed using the "leverage principle" and "the pressure is inversely proportional to the area". In order to enhance the strength and convenience of the cable cutter, the cable cutter has developed from the traditional manual cable cutter to the ratchet cable cutter, and then there are hydraulic cable cutters, electric hydraulic cable cutters, and all-electric cable cutters. [0003] Cable cutter is a common tool specially used for cutting cables in power line construction. The erection of transmission cables is mostly carried out in the field with poor construction conditions and lacks power such as powe...
