The invention discloses a T1T2 four-wire splitting and stranding mechanism, and belongs to a splitting mechanism. The T1T2 four-wire splitting and stranding mechanism comprises a fixing base, an uppersplitting finger clamp, a splitting finger seat back clamp, a splitting finger seat front clamp, a front clamping finger seat finger clamp, a back clamping finger seat finger clamp, a left strandingcrochet hook and a right stranding crochet hook, wherein the upper splitting finger clamp, the splitting finger seat back clamp, the splitting finger seat front clamp, the front clamping finger seat finger clamp and the back clamping finger seat finger clamp all clamp wires through finger opening and closing, the left stranding crochet hook and the right stranding crochet hook rotate under the driving of a motor, and the right stranding crochet hook moves left and right to realize wire stranding at different positions of the wires. The T1T2 four-wire splitting and stranding mechanism clamp different wires in a coil through the upper splitting finger clamp, the splitting finger seat back clamp, the splitting finger seat front clamp, the front clamping finger seat finger clamp and the back clamping finger seat finger clamp, splits the coil by being cooperated with the left stranding crochet hook and the right stranding crochet hook, and is good in splitting effect, high in intelligent degree and significantly improved in splitting efficiency.
