[0015] 1. By setting up a disassembly mechanism, when the RV expansion box is quickly disassembled and installed, the tooth block on one side of the mounting plate cooperates with the gear to adjust the position of the side expansion box. When the screw is turned, the other card plate moves upward to release the restriction on the mounting plate. The extruded spring telescopic rod drives the mounting plate on one of the card plates to move upward and staggered with the gear, so that the mounting plate can be disassembled and the limit of the opposite side expansion box can be released. The RV expansion box can be quickly disassembled and repaired. The mounting plate is T-shaped, and the two card plates are L-shaped, which can limit the mounting plate. The side expansion box can be quickly disassembled by cooperating with the slider and the slide groove. The limit plate can be clamped in the car body through the limit ring on its surface to limit the sliding, and the side expansion box can be quickly disassembled and repaired, thereby improving the use effect of the device.

[0016] 2. By setting up a support assembly, when the side expansion box is disassembled, the support rod at the bottom of the side expansion box can support the side expansion box to prevent the side expansion box from shaking and tilting during disassembly, thereby improving the disassembly efficiency of the device. The first slot can prevent the support rod from being installed, and a fixed rod is provided between the two support rods to provide limited support thereto. The second slot can limit the installation of the fixed rod, thereby improving the disassembly efficiency of the device when the RV expansion box is disassembled and repaired.
