Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a multilayer circuit board structure, includes a plurality of parallel arrangement's circuit board 1, and is adjacent pass through 2 electric connection of data line between the circuit board 1, and data line 2 is the flexible line, the both ends of circuit board 1 all are equipped with mounting bracket 3, mounting bracket 3 includes a plurality of parallel arrangement's horizontal pole 4 and is located the pole setting 5 at horizontal pole 4 both ends, the tip and the pole setting 5 of horizontal pole 4 are articulated, 6 fixedly connected with U-shaped plate 7 of screw are passed through to one side of horizontal pole 4, and the setting of 1 tip of circuit board is inboard at U-shaped

plate
