[0020] The boom leveling structure of the utility model comprises a leveling structure 1 and a base structure 2. The side of the leveling structure 1 is connected to the oil cylinder 3 through the shaft 1 5 passing through the baffle 4. The leveling structure 1 comprises a vehicle-mounted crane mounting plate 6, a leveling structure box 7, a shaft 2 8, a cushion block 9 and an ear plate 10. The vehicle-mounted crane mounting plate 6 is located above the leveling structure box 7. The shaft 2 8 passes through the leveling structure box 7. A cushion block 9 is provided at the bottom of the leveling structure box 7. An ear plate 10 is provided at the side of the leveling structure box 7. Among them, the end of the oil cylinder 3 is located between the two ear plates 10, and the shaft 1 5 passes through the baffle 4 and the ear plate 10.
