Preferably, a plurality of grooves are formed in the bottom of the first base, a second hydraulic cylinder is arranged in each groove, the telescopic end of each second hydraulic cylinder is vertically arranged downwards, the telescopic end of each second hydraulic cylinder is connected with a roller, and each second hydraulic cylinder is electrically connected with the controller.

Preferably, at least ten grooves are formed in the first base and are uniformly distributed at the bottom of the first base.

Preferably, four buffer mechanisms are provided, and are spaced apart from the first hydraulic cylinder.

The utility model has the beneficial effects that: the position of the base is adjusted through the first hydraulic cylinder and the horizontal sensor, so that the base is kept in a horizontal state, and the base is prevented from shaking by matching with the buffer mechanisms arranged at intervals, so that the stability of the base is improved; set up a plurality of recesses in the bottom of first base to set up the gyro wheel that can stretch out and draw back in the recess, can control the base through control second pneumatic cylinder extension and slide, can control the base fixed when control second pneumatic cylinder 71 shortens, it is more convenient.

The features and advantages of the present invention will be described in detail by embodiments in conjunction with the accompanying drawings.
