[0021] 1. For this easily disassembled and assembled electric roller, when disassembly and maintenance are required, after removing the wiring terminal box and the support, pull the movable rod outwards of the connecting cylinder until the protruding insertion block on the support rod disengages from the slot, and then rotate the support rod outside the limit disk. The limit disk is disengaged from the fixation of the support rod, and the limit disk can be rotated clockwise until the limit disk disengages from the clamping groove on the limit post, so that the limit disk can be separated from the end cover. Since the end cover is no longer limited by the limit disk, the end cover can be pulled out to be separated from the cylinder body, facilitating the extraction of the parts inside the cylinder body for maintenance.

[0022] 2. When the easily disassembled and assembled electric roller needs to be installed, place the parts inside the cylinder body. The two end covers respectively penetrate the front shaft and the rear shaft. After the limit disc penetrates the limit post, rotate the limit disc for clamping. Then insert the support rod into the slot. Since a spring is installed between the movable rod and the connecting cylinder, the spring resets and drives the movable rod to move towards the inside of the connecting cylinder, which can fix the limit disc and plays a role in facilitating installation.
