Three-point fixing double-hinge nail plate
The invention discloses a three-point fixing double-hinge nail plate which comprises a nail plate and a box, wherein the nail plate has a foldable rhombus structure; the box is used for storing the nail plate; the nail plate is formed by connecting a plurality of rhombus units; an intersection point of two adjacent edges of one rhombus unit is arranged on an end part of the nail plate; the intersection point is fixed with the box through a bolt; two fixing points are respectively arranged on the box on the two sides of the intersection point; bendable hinges are respectively mounted at the two fixing points; the hinges are connected with the corresponding rhombus unit. Compared with the prior art, the three-point fixing double-hinge nail plate has the advantages that the connection of the box and the nail plate is arranged as three-point fixing, the nail plate is effectively prevented from off-tracking during a forward extending process, a box opening is prevented from inclining, and similarly, when the nail plate is folded, the nail plate can quickly and smoothly enter into the box.
