The invention provides a magnetic resonance cervical coil which comprises a rotating bottom cover, a sliding rod, a body, a first rotating rod, a second rotating rod, a third rotating rod and a cylindrical surface circuit. External threads are arranged on the outer side of the top of the rotating bottom cover, a groove is formed in the bottom of the body, internal threads matched with the externalthreads are arranged on the inner wall of the groove, through holes for containing the sliding rod is formed along the center of the groove, a first rotating rod is hinged to the top of the body, thefirst rotating rod is further hinged to the second rotating rod, a coil on the lower surface of the cylindrical surface circuit penetrates through the through hole formed in the second rotating rod,a preset position between the two ends of the second rotating rod is hinged to a first position of the top of the sliding rod, one end of the third rotating rod is hinged to a second position of the top of the sliding rod, the second position is higher than the first position, and a radio frequency coil on the upper surface of the cylindrical circuit penetrates through the through hole formed in the other end of the third rotating rod, so that the imaging quality can be improved.
