Knitted cage and weaving method

The invention discloses a knitting cage and a knitting method.The knitting method comprises the following steps that S1, an upper mold disc with a first fixing piece and a lower mold disc with a second fixing piece are selected, and then a keel frame is fixedly connected between the upper mold disc and the lower mold disc; s2, after a weaving strip is selected to be bent in a half-and-half mode, the two ends of the weaving strip firstly penetrate into two adjacent first insertion holes in a first fixing piece downwards; s3, the two ends of the woven strip downwards penetrate into two second inserting holes in a second fixing piece, and then the two ends of the woven strip are bent upwards to penetrate into two third inserting holes; s4, the woven strip is tensioned so that the woven strip can tightly abut against the hoop ring of the keel frame, and then redundant parts of the two ends of the woven strip are cut off; and S5, the steps S2, S3 and S4 are repeated in sequence until knitting of all the knitting s
