Furthermore, the worker only needs to put down the supporting leg to connect the universal wheel with the ground, thereby reducing the difficulty of operation for the worker.

[0012] Furthermore, a connecting rod is installed between two supporting rods close to each other.

[0013] By adopting the above technical solution, when the staff pulls the connecting rod, the two support rods on the same side move downward synchronously, thereby reducing the operating difficulty of the staff and improving the efficiency of the staff.

[0014] Furthermore, a return spring is fixed to the upper surface of the sliding block, and the other end of the return spring is fixed to the inner top wall of the sliding groove.

[0015] By adopting the above technical solution, when the support rod is not subjected to external force, the slider and the support rod remain stable under the action of the return spring, so that the support rod remains suspended, thereby reducing the probability of the support rod interfering with the movement of the universal wheel.

[0016] Furthermore, a placement plate is provided on the bottom surface of the support plate to reduce the difficulty for workers to lift the cutting device.
