Quick release structure to allow additional rotational access, supporting structure, and housing

A housing comprising:

• housing walls defining an opening;
• a cover rotatably arranged on the housing walls, the cover configured to cover the opening;
• a telescopic rod for rotating the cover to expose the opening;
• and
• a quick release structure:
• a support base fixed to the cover;
• a connector slidably and detachably arranged on the support base, the connector defining a holding hole, wherein the connector is rotatably connected to an end of the telescopic rod, another end of the telescopic rod is rotatably connected to one of the housing walls;
• and
• a lock comprising:
• a locking body positioned on the support base;
• and
• a clamping shaft slidably positioned on the locking body, wherein
• a sliding direction of the clamping shaft intersects with a sliding direction of the connector along the support base, and the clamping shaft is inserted into or is withdrawn from the holding hole to connect or separate the support base and the connector, respectively, when the support base and the connector are separated, the cover is rotatable further to a side of the housing walls such that the opening is completely exposed.
