CRADLE HEAD, HANDLE CRADLE HEAD, LOCKING STRUCTURE, AND CONTROL METHOD

摘要

A cradle head, a handle cradle head, a locking structure, and a control method. The cradle head comprises a rotational member (21), a bearing member (22) rotationally connected to the rotational member (21), and a locking structure (6). The locking structure (6) is provided on one of the rotational member (21) and the bearing member (22), and used for being clamped with the other one of the rotational member (21) and the bearing member (22), so as to lock a relative rotation position between the rotational member (21) and the bearing member (22). A translation axis structure (2) of the cradle head can be locked conveniently and quickly.
