[0033] To summarize, during installation, the insert rod 470 is inserted into the slot 410 so that the inclined surface of the insert rod 470 squeezes the inclined surface of the block 440, so that the blocks 440 move away from each other and squeeze the connecting spring 460. When the block 440 is aligned with the slot 480, the block 440 is embedded in the slot 480 through the reset of the connecting spring 460 to complete the fixation. During disassembly, only the connecting plate 450 needs to be pulled to remove the block 440 from the slot 480, thereby avoiding the use of bolts for disassembly and assembly, making disassembly and assembly quick and rapid, saving time and effort, facilitating subsequent maintenance, and improving the practicality of the device.
