Open pliers type gear mechanism, pliers-type gear opening and closing mechanism and the winding machine

摘要

A forcipate gear open-close mechanism comprises a circular ring-shaped base (1) spliced by two parts, an annular gear (2) spliced by two parts, and an open-close device for driving the circular ring-shaped base (1) and the annular gear (2) to open or close. An annular guide rail (11) formed by splicing is arranged on the circular ring-shaped base (1); the annular gear (2) is mounted on the annular guide rail (11); and a power transmission device (4) drives the annular gear (2) to rotate along the annular guide rail (11). The annular gear (2) and the circular ring-shaped base (1) are each spliced by two parts; therefore, the gear mechanism can be clamped on an iron core conveniently, and a coil can be wound on a three-dimensional iron core conveniently. Moreover, the gear mechanism can not only be clamped on an iron core, but also be clamped on a columnar iron core.
