Visitor mode is to encapsulate some operations applied to a certain data structure. Once these operations need to be modified, the data structure that accepts this operation can be saved unchanged. Visitor mode is suitable for systems with relatively stable data structures. It reduces the coupling degree between data structures and operations acting on data structures, making the set of operations relatively free to change. The specific structure diagram is as follows:

The weightlifting belt prevents spinal hyperextension by forming a hard posterior wall surrounding the lower torso and connecting the ribs and hip bones. This not only limits the backward movement of the spine, but also prevents the scoliosis and rotation of the spine. You can think of the belt as an external bone, which connects the ribs and hips by surrounding them, thus increasing stability.

Due to the large range of movements, the normal binding method (front binding) of the conventional weightlifting belt (narrow front and wide back) is also to achieve this goal.
