Spinning thread positioning device with anti-falling structure

The invention relates to the technical field of spinning, in particular to a spinning thread positioning device with an anti-falling structure, which comprises a rack, a mounting seat and a positioning assembly, the positioning assembly comprises a base, a top frame, a pressing mechanism and an adjusting mechanism, the base is arranged on the mounting seat and is in sliding connection with the mounting seat, a tensioning wheel is arranged on the base, and the adjusting mechanism is arranged on the top frame. The top frame is arranged over the bottom plate and connected with the bases, the downward pressing mechanism is used for pressing the spinning threads located between the two tensioning wheels, and the adjusting mechanism is arranged between the two adjacent bases and used for adjusting the distance between the two adjacent bases. According to the technical scheme, the distance between every two adjacent bases is more accurately adjusted through the adjusting mechanism, multiple spinning threads are prev
