Return torsion spring mounting pressing sheet and manufacturing method thereof

The invention relates to a return torsion spring mounting pressing sheet and a manufacturing method thereof. The return torsion spring mounting pressing sheet is provided with a main plate and an auxiliary plate; the main plate is arranged above the auxiliary plate in parallel; return torsion spring mounting holes are formed in the main plate and the auxiliary plate correspondingly; the left side, the right side and the front side of the main plate can be bent downwards to form a left block piece, a right block piece and a front block piece correspondingly; and the rear side of the main plate is connected with the auxiliary plate into a whole. The manufacturing method is characterized in that a metal plate piece in a predetermined shape is obtained by utilizing a cutting mode; a large end part of the metal plate piece is the corresponding main plate; a small end part of the metal plate piece is the corresponding auxiliary plate; and the return torsion spring mounting holes are formed in the large end part and the small end part of the metal plate piece correspondingly.
