New description: [New technical field] This is a new type of two-wheeled central control caster, which can be controlled by the user as two-stage control for free steering, linear rolling or stopping. [Prior Art] The conventional two-wheeled medium-controlled casters can only control the brakes. Only a few of the transport beds used in medical institutions have a direct-oriented directional structure. The directional structure is additionally operated, and the brakes and directional structures are set. On the casters: With the foot stepping control, separate operation, report inconvenient. [New content] Eight XT X-type T-controlled casters can be controlled by the user's two-stage control for free steering, linear rolling or squatting, so as to achieve the convenience of operation.
