The connecting frame 1 can be composed of two opposite connecting vertical rods and a mounting plate 2 installed at the bottom of the connecting vertical rods. The two mounting plates 2 respectively form mounting working surfaces located at the front and rear sides of the leveling frame. The rear mounting plate 2 is equipped with a supporting long tube 4. The other end of the supporting long tube 4 extends to the front side of the connecting frame 1.
