The umbrella holder consists of a holder with rod and screw thread + a ring.
The ring is about the end of the handle and the rod in the ring, which also contains screw thread. By turning the umbrella holder in the ring, the ring clamps around the tube of the handle. This way you can fix the handle. Just tighten, it does not hurt. If the umbrella is in it can slowly drop down because the clamp is not tightened properly enough. Especially for the ladies, use 2 hands to turn.
Pull the silver button with elastic down, then raise the button, pull the elastic around the thin rod of the umbrella and over the silver button again. This ensures that the umbrella does not blow out of the holder.
