Each leg set includes two U-shaped standing legs coupled with each other to form the respective leg set having a “X” structure. The interlocking arrangement includes a locking sleeve having a locking socket provided at one of the leg sets between a supporting portion and a ground portion, and a detachable locker which is provided at another the leg set between the supporting portion and the ground portion and is detachably inserted into the locking socket of the locker to detachably couple the two leg sets with each other such that the interlocking arrangement forms a center axis of the leg frame that the two leg sets are allowed to adjust a set-up angle therebetween so as to substantially support the tabletop.
