Tension-adjustable thread twisting device

The utility model provides a tension-adjustable thread twisting device, which comprises a mounting plate, a plurality of groups of adjusting assemblies for adjusting threading tension are equidistantly mounted on the surface of the mounting plate, each adjusting assembly comprises a turntable, the circle center of each turntable is rotatably connected with the mounting plate through a bearing, and four groups of thread frames are symmetrically arranged on the circle center of the outer side surface of each turntable. Compared with the prior art, the diameters of the yarn frames in the four adjusting assemblies can be adjusted at the same time through the driving assembly, then the tension of yarns is adjusted, the yarns of the same type can be connected with a traction rope according to the types of the yarns, synchronous rotation is conducted, and different types of yarns can be independently adjusted manually; the overall tension adjusting efficiency is improved, after adjustment is completed, the rotating
