The utility model discloses an electrical threading apparatus for building electrical, and relates to the technical field of building
engineering, the electrical threading apparatus comprises a box body, an adjusting
assembly is installed in the box body, the adjusting
assembly comprises an inner support
assembly and a rotating telescopic assembly, the inner support assembly comprises a first motor installed in the box body, the output end of the first motor is connected with an installation column, and the installation column is connected with the rotating telescopic assembly. The end, close to the first motor, of the mounting column is fixedly connected with a rotary disc, the mounting column is sleeved with a sliding sleeve column, the outer wall of the sliding sleeve column is rotationally connected with twelve connecting rods, and the ends, away from the sliding sleeve column, of every two connecting rods are rotationally connected with a supporting plate. According to the utility model, the
diameter of the sleeve is changed by utilizing the adjusting component, so that the device is suitable for pulling ropes made of different materials, the bending stress of the sleeve due to overlarge
diameter is reduced, and the problems of breakage of the pulling ropes or loosening and knotting due to small
diameter of the sleeve are avoided.
