Ground anchor lock

A ground anchor for securing portable objects to the ground, the anchor comprising:

• a main elongated shaft having upper and lower ends, a grooved locking post extending upwardly on and fixed to the upper end, an auger fixed to the lower end, an engagement area between the grooved locking post and the auger and configured for releasably engaging an external device for screwing the main shaft into the ground;
• a sleeve slidably mounted over the main shaft between the grooved locking post and the auger, configured to rotate freely around the main shaft and obstruct access to the main shaft to prevent persons from gripping, rotating, and removing the main shaft;
• an attachment member attachable to the main shaft above the sleeve, comprising at least two holes, a first hole being suitably sized to allow the grooved locking post to pass through but not the sleeve, and at least a second hole configured to releasably secure one or more of an external lock, chain, tether, rope or cable attachable to one or more portable objects to anchor the objects when the main shaft is screwed into the ground;
• and
• a lock device configured to cover and releasably lock onto the grooved locking post so the attachment member and sleeve cannot be removed and the main shaft is covered by the sleeve.
