[0036] See also Figure 1 , 2, 3, 4 and 5, the fastening assembly 200 includes a hydraulic rod 210, a movable plate 220, a clamping piece 240, a clamping plate 250 and a connecting rod 260, the hydraulic rod 210 is installed on the top of the movable frame 150, the movable plate 220 is slidably arranged in the movable frame 150 and is connected to the hydraulic rod 210, the clamping piece 240 is arranged on the top of the movable plate 220, the connecting rod 260 is arranged on the top of the clamping plate 250, the connecting rod 260 slides through the movable plate 220 and is clamped on the clamping piece 240.
