The two leather collar working face monomers can work independently without being influenced, so that the stability can be improved, and the phenomena of position deviation and overlapping of the leather collars are avoided.

(III) advantageous effects

The utility model has the advantages that:

the utility model forms an inner concave part in the middle of the working surface of the leather collar, when the leather collar rotates along with the roller, the vortex formed in the inner concave part is helpful for the movement of the leather collar, so that the leather collar moves more freely and stably, and the problems of accumulated flowers, dead jaw and the like caused by matching with the groove do not exist, and finally the yarn quality is improved; the working efficiency is improved, and the service life is prolonged. In addition, a plurality of limiting pins are arranged at the top of the working surface of the leather ring, for example, two leather ring sliding grooves are formed on three limiting pins, so that two drafting channels are formed, the two leather rings stably run in the respective drafting channels respectively, and the phenomena of deviation of the leather rings and overlapping of the leather rings are avoided.
