The pin shaft baffle 16 and the rotary pin shaft 14 are connected into one body by the limit screw 17. After use, by disassembling the rotary pin shaft 14, it is convenient for the staff to separate the fixed horizontal plate 3 from the horizontal rib plate 10;

[0032] Embodiment three;

[0033] Please refer to Figures 2 to 6 , in order to more conveniently adjust the position of the lifting oil cylinder 5, one end of the fixed horizontal plate 3 is fixedly connected with a fixed vertical plate 4 for limit.

Then, according to actual needs, the staff member starts the lifting oil cylinder 5, causing it to push the telescopic rod 6 downward. The telescopic rod 6 drives the load-bearing plate 7 to descend, thereby lifting the gantry shear body 1. After a sufficient distance is generated between the lower end of the gantry shear body 1 and the ground, an external mobile device is sent to the lower end of the gantry shear body 1 to support and move it. After the movement is completed, the lifting oil cylinder 5 is started to make the telescopic rod 6 rise, driving the load-bearing plate 7 to rise, thereby causing the gantry shear body 1 to descend and reset. Then, the lifting oil cylinder 5 is pushed to make it rotate to reach the folded state.
