[0003] The utility model with publication number CN219174738U discloses a cam structure of circular knitting machine. The needle thread enters the forming cavity from the needle entry end of the right end of the cam. Firstly, the needle thread passes through the trapezoidal retention groove to form a wider spacing, so that the woven fabric has better air permeability. Then, the needle thread is woven into shape through the inverted V-shaped guide groove and is discharged from the left side of the cam. The trapezoidal retention groove and the inverted V-shaped guide groove make the woven thread less likely to break and the woven fabric has better air permeability.

[0004] However, the cam structure of the circular knitting machine disclosed above has the following problems in actual use: although the cam body is positioned and installed through the cam seat to realize the knitting, the cam body needs to be independently adjusted when the knitting pattern is changed. Each group of cam seats needs to be fastened and loosened through the bolts to realize the disassembly and assembly of the cam body. In addition, the adjacent cam bodies cannot effectively enter the needle continuously, which is easy to cause the breakage of the knitting needle, shortens the service life of the knitting needle, and causes the cam to be easily worn.

[0005] Therefore, a cam structure for a circular knitting machine is proposed to solve the above problems. UTILITY MODEL CONTENTS
