A handle is configured to be rotated 180 degrees. The handle is divided into a first portion, a second portion, a third portion, and a fourth portion in clockwise order. The first portion and the third portion are rotated 90 degrees in the clockwise direction, and the second portion and the fourth portion are rotated 90 degrees in the counter-clockwise direction. Therefore, the first portion and the fourth portion, and the second portion and the third portion are formed to be attached to each other. When the length of the handle is 50 cm, the handle is configured to enable the half of the handle to be rotated. |
