The invention discloses a folding type training table which comprises a tabletop board and supporting legs. The tabletop board is connected to the upper ends of the supporting legs through a turning adjusting device. The turning adjusting device comprises a rotary connecting structure and an insertion locking structure. The rotary connecting structure comprises a shaft head fixed to the top ends of the supporting legs and a rotating shaft connected to the tabletop board. The shaft head is matched with the rotating shaft. The insertion locking structure is installed on one side of the rotary connecting structure and comprises a movable base, an insertion movable body, a gear and a handle. The gear and a wrench are coaxially connected to the movable base. A rack is formed on the insertion movable body. An insertion hole is formed in the outer edge of the shaft head. A clamping bolt is connected to the end of the insertion movable body. The training table of the structure is simple in overall structure, does not occupy space after being folded, and is light in structure and convenient to transport; due to the simple structure of the table, the supporting legs can be staggered, and the space can be saved to the maximum extent.
