A forcipate gear open-close mechanism comprises a circular base (1) spliced by two parts, an annular gear (2) spliced by two parts, and an open-close device for driving the circular base (1) and the annular gear (2) to open or close. An annular guide rail (11) formed by splicing is arranged on the circular 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. |
