[0002] A circular knitting machine, scientifically named a circular weft knitting machine (or called a circular weft knitting machine). Due to the large number of loop-forming systems (referred to as the number of yarn feeding paths or loop-forming paths in enterprises, abbreviated as paths) of circular knitting machines, high speed, high output, fast pattern change, good fabric quality, few processes, and strong product adaptability, they have developed rapidly.
[0003] Existing circular knitting machines are generally directly fixed on the ground. During the high-speed operation of circular knitting machines, certain vibrations will be generated. The vibrations of the machine table will indirectly affect the quality of the products manufactured by the circular knitting machine. If jitter occurs and displacement occurs, it is inevitable that drops will occur on the bearing plate, resulting in phenomena such as bumps, which increases the use cost of the shock-absorbing base of the circular knitting machine.

[0012] Furthermore, a "T"-shaped structure groove is formed on the inner wall of the connecting member, and the connecting plate can slide left and right along the inside of the connecting member.
[0013] Furthermore, the buffer mechanism includes a buffer plate, a return spring, a buffer rod, a support plate, and a damping spring shock absorber. The buffer plate is slidably clamped on the outer surface of the slide rod body. The return spring is sleeved on the outer surface of the slide rod body, and one end of the return spring is connected to the buffer plate.

When the large circular machine body 1 is pressed down, the support plate 14 is pushed to move downward, and then, the buffer plate 11 is pushed to slide along the outer surface of the sliding rod body 10 through the buffer rod 13. The provided return spring 12 can reset the buffer plate 11, so that the device has a good buffer and shock absorption effect and can avoid large shaking amplitude from affecting subsequent processing;
