Description

Cable cutter

The utility model relates to a kind of cable cutter, and utilize the tooth bar propulsive mechanism to promote rotating blade and shear cable, this cable cutter rapid operation, shearing area is neat.

Cable cutter commonly used, the main blade that a band arc inner edge is arranged, on it by the hinged rotating blade of hinge with fan-shaped external tooth and arc inner edge, the main blade bottom is provided with the pedestal mainboard, main shaft and pedestal cover plate are housed on it, control handle and the pedestal cover plate is connected, on main shaft, install and have propelling cam and the propelling tooth bar that advances handle, this cable cutter utilizes the tooth bar propulsive mechanism to promote rotating blade and shears cable.But this cable cutter does not have retraction mechanism, if conversion clipped position in operation, very inconvenience because main blade and rotating blade are hinged by a hinge at its top, easily produces the gap between two blades, cause that the part cable jumps the queue in blade, cause shearing area irregular.

The purpose of this utility model is to provide a kind of cable cutter, this cable cutter, can be in operation withdrawing at any time, flexible transformation clipped position, and shearing area is neat.

The purpose of this utility model is achieved in that a kind of cable cutter, the main blade that a band arc inner edge is arranged, on it by the hinged rotating blade of hinge with fan-shaped external tooth and arc inner edge, the main blade bottom is provided with the pedestal mainboard, main shaft and pedestal cover plate are housed on it, control handle and the pedestal cover plate is connected, the retaining ratchet that cooperates with fan-shaped external tooth is installed on the pedestal mainboard, on main shaft, install and have the propelling cam that advances handle and advance tooth bar, advance a withdrawing pin is installed on the tooth bar, a flanging is arranged at pedestal cover plate top, and this flanging and pedestal mainboard constitute the gathering sill of rotating blade jointly.The utility model advances handle to promote the rotating blade rotation and then shear cable through tooth bar by rotating, after stirring the withdrawing pin clockwise and opening the retaining ratchet, withdrawing or rapid feed rapidly, because rotating blade is the center with the hinge, its outer rim is rotated in gathering sill, blade is stressed reasonable in the process of shearing cable, can not cause the buckling deformation of blade.

The utility model compared with the prior art have can be in operation withdrawing at any time, rapid feed, flexible transformation clipped position, and the neat advantage of shearing area.

The utility model is described in further detail below in conjunction with drawings and Examples.
