A body hanger in a coating line according to claim 8, wherein: the linkage mechanism comprises: the swing rod is arranged below the main hanging beam, the middle of the swing rod is hinged with the main hanging beam, the four push-pull rods are respectively arranged on the front side and the rear side of the swing rod, the two ends of the swing rod are respectively hinged with one end of one transmission rod, the two push-pull rods on the front side and the inner ends of the two push-pull rods on the rear side are respectively hinged through a third hinging shaft, the other ends of the two transmission rods are respectively movably connected with the two third hinging shafts, the upper ends of the two third hinging shafts are slidably arranged on the main hanging beam, the third hinging shafts can slide along the main hanging beam, but cannot be separated from the main hanging beam, the outer ends of the two push-pull rods on the front side and the two push-pull rods on the rear side are respectively hinged with the left side and the right side of the folding frame on which the main hanging beam is arranged, so that the two push-pull rods connected with the folding frame can prevent the folding frame from rotating around the first hinging shaft on the folding frame as a whole, but do not prevent the folding frame from being folded or unfolded, and when any folding frame is folded along the folding frame or the folding frame is unfolded, the folding frame can be simultaneously driven to be unfolded along the second hinging shaft through the second hinging shaft and the second hinging shaft.

10. A body hanger in a coating line according to claim 9, wherein: the two push-pull rods at the front side and the two push-pull rods at the rear side are respectively coaxially connected with the two short connecting rods which are close to each other at the side where the push-pull rods are positioned to form a rod piece.

11. A body hanger in a coating line according to claim 9, wherein: the mounting structure between the third hinge shaft and the main hanging beam is as follows: the top of the third hinge shaft is provided with a chuck, the side wall of the main hanging beam is provided with a clamping groove arranged along the main hanging beam, and the chuck can be clamped in the clamping groove in a sliding manner along the clamping groove, so that the third hinge shaft can slide along the main hanging beam but cannot be separated from the main hanging beam.

12. A body hanger in a coating line according to claim 2 or 3 or 4 or 5 or 6 or 7, characterized in that: the horizontal pole is L shape section bar, and L shape section bar includes a horizontal limit and a perpendicular limit, is provided with a plurality of through-hole respectively on horizontal limit and perpendicular limit, and the through-hole on the perpendicular limit can be regarded as pendant portion.

13. A body hanger in a coating line according to claim 7, wherein: the middle cross rod is also provided with a scale, one end of the scale is hinged with the middle cross rod, so that the scale can rotate around a hinge point, and the scale can be used for measuring the distance between two adjacent cross rods.

14. A body hanger in a coating line according to claim 1 or 2 or 3 or 4 or 5 or 6 or 7, characterized in that: the two stay cord structures are arranged, and the two stay cord structures are respectively arranged on the left side and the right side of the main hanging beam.
