Holding device for top-opening substrate container

A holding device for a top-opening substrate container, the top-opening substrate container comprising a container body and a container door structure, the container door structure configured to be combined with the container body so as to define a receiving space for accommodating a plurality of substrates;

• the holding device comprising:
• a substrate actuator, disposed at an outer side part of the substrates;
• and
• a holding assembly, disposed in the receiving space, the holding assembly for pushing the substrate actuator to operate, the holding assembly comprising:
• a holding body, disposed at an inner side part of the container body;
• and
• a pushing actuator, disposed at the holding body, the pushing actuator comprising:
• a first guiding sloped surface, for pressing against a second guiding sloped surface of an inner surface of the container door structure, the first guiding sloped surface causing corresponding pushing and displacement between the first guiding sloped surface and the second guiding sloped surface according to a supporting force of the container door structure;
• and
• a pushing section connected to the first guiding sloped surface, the pushing section corresponding to a position of the substrate actuator and correspondingly pushing the substrate actuator to operate according to a level of the pushing and displacement of the first guiding sloped surface, such that the substrate actuator displaces the substrate until the plurality of substrates are stacked and positioned with one another.
