Abstract
A manual banner roll-up mechanism has a first tube, a second tube, a foldable material, a securing base, a washer, a linking member, a rope, a securing cylinder, a first plug and two mounting supports. The first tube is rolled up with a foldable material. Another end of the foldable material is connected to a second tube. One end of the first tube is jacketed by a securing base, and the washer, the triggering member and the rope are locked onto the securing cylinder by a bolt. Another end of the first tube is jacketed by the first plug that has a base, a positioning member, a spring, and a cover. A first positioning member of the securing base and a second positioning member of the first plug enable the first tube to be hung between the two mounting supports.
