To prevent water leakage, the gap is filled and the secondary housing 202 is initially fixed to prevent the connection between the main housing 201 and the secondary housing 202 from shaking during the subsequent fixing process. Then, the internal hexagonal screw 207 inside the internal threaded tube 206 is rotated until the bottom end of the internal hexagonal screw 207 presses against the top surface of the pull rod 204 to support the secondary housing 202. This prevents the bottom end of the secondary housing 202 from being suspended and causing a decrease in strength, improves the safety of the installation, facilitates installation and transportation, allows for easy adjustment of size according to the installation position, and makes installation and adjustment simple and quick. The operation is convenient and effectively improves the efficiency of installation.

[0034] After the initial installation is completed, the snap-fit ​​plate 302 is embedded in the mounting hole 301, and the isolation plate 305 is snapped between the two snap-fit ​​plates 302 in the same vertical plane. Then, screws are installed in the fixing hole 304 to fix the bonding plate 303 to the outside of the main box 201 and the auxiliary box 202 to separate the internal space. The hanging plate 307 is pulled along the guide rail 306 to adjust the height of the hanging plate 307. The electrical equipment is installed on the hanging plate 307. If it is not necessary to separate the space, the snap-fit ​​plate 302 can be installed in the mounting hole 301. This makes it convenient to install electrical equipment as needed and further improves the convenience of use.
