The lower side of the U-shaped frame 1 is provided with an H-shaped bottom plate 5, and the output ends of the two second cylinders 4 are fixedly connected with the two sides of the upper surface of the H-shaped bottom plate 5. The device can move flexibly by the universal wheels 3. The second cylinder 4 and the H-shaped bottom plate 5 can cooperate to assist in supporting and positioning the device after it is moved to a specified position.
