[0038] Working principle: First, when installing the yarn spindle roll 3, first nest the yarn spindle roll 3 on the rotating shaft part 2. Then, press the circular button 505 to drive the driving connecting rod 501 to displace along the sliding groove a401 inside the shaft body 4, so that the driving connecting rod 501 rotates to drive the driving transmission rod 502 arranged around the driving connecting rod 501 to rotate, thereby making the transmission rod 502 drive the driving arm 503 to move, and making the driving arm 503 move outward along the shaft body 4. The outer side of the driving arm 503 is arc-shaped, and there are several saw teeth neatly arranged on the arc-shaped surface. The friction between the driving arm 503 and the inner wall of the yarn spindle roll 3 can be increased through the saw teeth, so that the yarn spindle roll 3 can be fixed by the driving arm 503. Installing the yarn spindle roll 3 on the rotating shaft part 2 has a simple and fast installation process, improving the efficiency of warping and unwinding the warp yarn.

[0039] Secondly, when the warp yarn on the yarn spindle roll 3 is used up, press the two clamping blocks 601 inward to overcome the elastic force of the spring 602 and slide inside the shaft body 4, so that the clamping block 601 is unlocked from the clamping teeth 504. Then, pull the unlocked driving connecting rod 501 outward, so that the driving connecting rod 501 displaces along the sliding groove a401 inside the shaft body 4, and the driving connecting rod 501 rotates to drive the driving transmission rod 502 arranged around the driving connecting rod 501 to rotate, thereby making the transmission rod 502 drive the driving arm 503 to move, and making the driving arm 503 move inward along the shaft body 4, so that the four driving arms 503 contract inward, and the used-up yarn spindle roll 3 can be removed.
