[0048] Furthermore, in order to facilitate the slotting, the lower accommodating groove portion 41 is in a triangular block shape.

[0049] Furthermore, since the weight of the substrate 1 is relatively large, in order not to affect the printing format, mounting holes 6 are provided on the four walls of the substrate 1, and the mounting holes 6 are used to install hanging parts. Furthermore, the hanging parts are hanging screws.

[0050] Furthermore, the installation tool is an adjustable wrench.
