Metal wire bending testing machine

The invention relates to a metal wire bending testing machine, which comprises a base, one side of the top side of the base is fixedly connected with the lower end of a stand column, a swing mechanismis fixedly installed at the upper end of the stand column, and the right end of an output shaft of the swing mechanism is fixedly connected with the middle of the left side of a swing plate; two shifting rods in front-back symmetry are mounted at the lower end of the right side of the swing plate, and a coaxial first bevel gear is fixedly mounted on the right side of the periphery of an output shaft of the swing mechanism. The metal wire bending testing machine is simple in structure and ingenious in conception, a metal wire fixing device can rotate along with swinging of the metal wire, andtherefore the axis of the metal wire close to the metal wire fixing device and the axis of a wiring hole of the metal wire fixing device are kept collinear, and bending of the metal wire close to themetal wire fixing device is reduced; the problem that the position, close to the metal wire fixing device, of the metal wire is broken more easily, and accuracy of a metal wire bending test is affected is solved, market requirements can be met, and popularization is facilitated.
