As shown in fig. 4, the touch support plate 1 of the present embodiment is formed by integrally molding two strip-shaped side plates 101 and two strip-shaped end plates 102, and is a square frame. Namely, a square hole is arranged in the touch support plate 1, and after the touch support is assembled, the square hole provides a deformation space for the elastic sheet 2.

The elastic sheet 2 is formed by integrally molding a connecting plate 201 and two Y-shaped plates 202 which are respectively arranged at two ends of the connecting plate; the open ends of the two Y-shaped plates 202 are respectively fixedly connected with the two strip-shaped end plates 102, that is, one connecting point 2a is formed between the open end of each Y-shaped plate 202 and one strip-shaped end plate 102; the contact 3 is arranged on the connecting plate 201, and the contact 3 is located at the center of the elastic sheet 2, as shown in fig. 2 and 3.

Specifically, as shown in fig. 2, the Y-shaped plate 202 is formed by integrally molding an opening end 202a and a connecting piece 202b, two side elastic pieces 203 respectively located at two sides of the connecting piece 202b are disposed at the rear end of the opening end 202a, and the side elastic pieces 203 are integrally molded with the opening end 202 a.

As shown in fig. 3, in the present embodiment, the mounting plate 4 is in a square frame shape, and the free ends of the four side elastic pieces 203 are respectively and fixedly connected with four corners of the mounting plate 4, and form four connection pivots 2b at the four corners respectively.

As shown in fig. 1 and fig. 3, the touch panel further includes a square reinforcing member 5, the reinforcing member 5 is fixedly disposed on the surface of the connecting plate 201 close to the touch panel, and the contact 3 is located in the reinforcing member 5. The reinforcement member 5 is used to keep the periphery of the contact 3 in a good balance state when the contact 3 moves in a direction approaching the touch panel.

In the present embodiment, the arch is actually a region of the elastic sheet 2 covered by the reinforcing member 5.

The structure also comprises two first reinforcing pieces 6, wherein the first reinforcing pieces 6 are Y-shaped; which are respectively fixed on the surfaces of the two Y-shaped plates 202 close to the touch panel.
