Folding Table with Adjustable Heights

A foldable table leg frame with adjustable heights, comprising:

• a first table leg (1) and a second table leg (2) arranged opposite each other;
• a first adjustment bar (3) hingedly connected to a bottom end of the first table leg (1), the first adjustment bar (3) being configured to flip up and down relative to the first table leg (1) to achieve height adjustment;
• a second adjustment bar (4) hingedly connected to a bottom end of the second table leg (2), the second adjustment bar (4) being configured to flip up and down relative to the second table leg (2) to achieve height adjustment;
• a first support bar (5) having a first end hinged to the first adjustment bar (3);
• a second support bar (6) having a first end hinged to the second adjustment bar (4), the second end of the first support bar (5) and the second end of the second support bar (6) being hinged to each other such that the first support bar (5) and the second support bar (6) are rotatable relative to each other,
• wherein, when the first adjustment bar (3) and the second adjustment bar (4) are flipped downward to a vertical state, the first support bar (5) and the second support bar (6) rotate into a straight-line state and jointly support between the first adjustment bar (3) and the second adjustment bar (4) to form a stable structure, and a locking mechanism (7) disposed between the first support bar (5) and the second support bar (6) to retain the first support bar (5) and the second support bar (6) in the straight-line state.
