Split core-changing rotating device

The utility model discloses a split core-changing rotating device. The lead frame solves the problem that an existing lead frame is time-consuming and labor-consuming in replacement of an envelope bobbin since the envelope bobbin can only be replaced after being detached when the envelope bobbin is used up. The device comprises a mounting plate, a locking mechanism and a plurality of rotating mechanisms are arranged on the mounting plate, each rotating mechanism comprises a rotating disc and a lead frame, and the lead frames are arranged on the rotating discs and driven by the rotating discs to move. The lead frame is provided with a first position used for leading wires during working and a second position where the rotating disc drives the lead frame to rotate and give way so as to replace a wire wrapping bobbin; and the locking mechanism is provided with a first state in which the rotating disc is interlocked and used for limiting the lead frame and a second state in which the rotating disc is locked and f
