[0041] During implementation, a rectangular groove 12 is provided at the top of the tailstock main frame 1 at the feeding end, and a driven sprocket or a driving sprocket is installed in the rectangular groove 12 through an adjusting shaft 22. Bar-shaped adjusting holes 13 are provided at the two side walls of the tailstock main frame 1 at the feeding end, and the adjusting shaft 22 is slidably installed in the adjusting holes 13. Adjusting rods 221 are radially fixedly connected to both sides of the adjusting shaft 22, and a hand wheel 222 is connected to one end of the adjusting rod 221 away from the adjusting shaft 22. A rear cover 7 for shielding the rectangular groove 12 and the sprocket 23 is installed at the feeding end of the tailstock main frame 1. Through the combination of the adjusting rod 221 and the hand wheel 222, the operator can easily control the position of the adjusting shaft 22, thereby facilitating the adjustment of the position of the sprocket 23, and then installing or removing the chain.
