The invention provides a locking structure for a variable-stiffness mechanical arm. The locking structure comprises a triggering module, a rotating module, a locking module and a shell. The rotating module comprises a reversing structure and a rotating jacking structure, a deep groove and a shallow groove are formed in the reversing structure, and the rotating jacking structure can move forwards and backwards along the shell and can rotate; the locking module comprises a rotating structure and an insertion tooth structure, the rotating structure is rotationally connected with the shell, and the insertion tooth structure can move forwards and backwards along the shell but cannot rotate relative to the shell. The minimally invasive surgical robot has the beneficial effects that the appearance is small, the joint rigidity is higher after locking, the response time is shorter, the defects that a traditional minimally invasive surgical robot is long in response time and small in joint rigidity improvement when use
