The junction of the first side wall 11 and the second side wall 12 is a positioning edge 14. The positioning template 1 is stacked on the reference surface of the mounting base, so that the first side wall 11 is aligned with the side wall surface of the mounting base, and the positioning edge 14 is aligned and overlapped with the positioning point on the reference surface, so that the installation position of the electrostatic discharger base can be determined through the first positioning hole 10, and a corresponding pneumatic tool is used to make a hole on the mounting base through the first positioning hole 10, so that a hole corresponding to the hole position on the electrostatic discharger base can be obtained.

[0046] Optionally, refer to Figure 3 The fixing frame 2 includes a first plate 21, a second plate 22 and a third plate 23 which are bent and connected in sequence to form a U shape. Figure 1 and Figure 2 The first plate 21 is stacked on the side of the positioning template 1 away from the reference plane, and the third plate 23 is located on the side of the mounting base away from the positioning template 1, that is, the positioning template 1 and the mounting base are sandwiched between the first plate 21 and the third plate 23. The third plate 23 is provided with a fixing hole 231, and a fixing member 232 is inserted into the fixing hole 231.

The above arrangement can effectively prevent the reference surface of the component mounting base from being scratched when the positioning template 1 moves on the reference surface, thereby ensuring the quality of the component.

[0055] Exemplarily, in this embodiment, both the first flexible layer and the second flexible layer are made of rubber material.
