1. A coil module, comprising a second coil mechanism, wherein the second coil mechanism comprises:
a third coil assembly;
a second base, corresponding to the third coil assembly, wherein the second base has a positioning assembly configured to correspond to a first coil mechanism;
a fourth coil assembly; and
a fifth coil assembly, wherein the third coil assembly, the fourth coil assembly, and the fifth coil assembly are electrically independent of each other;
the second coil mechanism further comprises a main axis, parallel to a third main body of the third coil assembly;
the third main body has a three-dimensional structure, extending along the main axis and having a tapered structure;
the fourth coil assembly is extended along the main axis, and the winding axis of the fourth coil assembly is parallel to the main axis;
the fourth coil assembly has a fourth main body, and the fourth main body has a three-dimensional structure extending along the main axis;
the fourth main body has a tapered structure tapering toward the third main body, and the third main body has the tapered structure tapering away from the fourth coil assembly;
the third coil assembly is extended along the main axis, the winding axis of a fifth main body of the fifth coil assembly is parallel to the main axis;
the fifth main body has a three-dimensional structure extending along the main axis;
as seen from the main axis, a gap is formed between the third main body and the fifth main body;
as seen from a direction perpendicular to the main axis, the third main body does not overlap the fifth main body;
wherein the second coil mechanism further comprises a sixth coil assembly, configured to perform a first function, the third coil assembly is configured to perform a second function, the first function is different from the second function, and a sixth main body of the sixth coil assembly has a plate structure;
as seen from the direction perpendicular to the main axis, the third main body does not overlap the sixth main body;
as seen from the direction perpendicular to the main axis, the third main body, the fourth main body, the fifth main body, and the sixth main body do not overlap.
