Casters are a collective term, including movable casters and fixed casters. Movable casters are so-called universal wheels. The 360-degree steering bracket or shell is equipped with wheels and can travel in any direction at will; the fixed caster fixed bracket is equipped with casters, which can only move in a straight line. These two kinds of casters are generally used in combination. For example, the structure of a trolley has two fixed wheels at the front, and two movable universal wheels at the back near the push armrest.
