[0030] II. In practical use, the operator can place the large hydraulic cylinder body between the left and right rotary drive structures 3 on the support frame 1 through the external auxiliary mechanism. At this time, the drive motor 42 in the left and right drive structure adjustment part 4 can be controlled to work simultaneously. The drive motor 42 inputs the rotational torque to the reducer 43.

At this time, the support rollers 57 provide auxiliary support for the long cylinder body. The above describes the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
