The push rod 7 has a limiting effect when sliding on the inner wall of the fixed plate 6.

During use, the first curved rod 22 drives the brake plate 24 to expand outward. When it is in contact with the drive ring 2, the effect of braking the large circular knitting machine is achieved by increasing the friction force.

[0030] Working principle: when the structure is needed, the transmission shaft body 3 is placed above the driving ring 2, and the driving ring 2 slides into the inner wall of the transmission shaft body 3. At this time, the driving shell 8 is driven by pressing the push rod 7 to compress the first spring 9.

During use, the limiting effect of the push rod 7 when sliding on the inner wall of the fixing plate 6 can further increase the stability of the driving shell 8. When the inclined push rod 12 slides on the inner wall of the push rod 7, the card plate 1 is driven by the inclined push rod 12. 3 slides out from the groove opened by the card shell 5, and when the driving shell 8 is pushed out to the outside by the first spring 9 during use by compressing the second spring 11, the card rod 10 is driven by the driving shell 8 to slide out from the inner wall of the fixing groove 4, so that the transmission shaft body 3 can be quickly disassembled during use, and the transmission shaft body 3 can be quickly fixed on the driving ring 2 during use. During use, the driving ring 2 can avoid the effect of damage to the transmission shaft body 3 due to friction when braking, and prolong the stability of the transmission shaft body 3 during use. The pressure cylinder 18 drives the connecting seat 20 to push or pull back. During use, the connecting seat 20 drives the first rotating shaft 21 and the first curved rod 22 to push out or pull back to drive the first curved rod 22 and the brake plate 24.
