s2, after the device moves to a certain position, the electromagnet (204 e) is electrified to attract the rectangular rod (204 b), when the rectangular rod (204 b) rotates along with the first rotating shaft (202) to be matched with the second rectangular groove (204 d), the rectangular rod (204 b) is inserted into the second rectangular groove (204 d), the threaded rod (203 b) rotates along with the first rotating shaft (202) to drive the threaded sleeve (203 e) to move up and down, and when the threaded sleeve (203 e) moves upwards, the push rod (203 f) can be driven to rotate, so that the rotating plate (203 d) rotates outwards and gradually opens, the contact area of the device and soil is increased, and the stability of the device is improved;

s3, the connecting rod (104) is taken down, one end of the connecting wire (308 e) is inserted into the connecting hole (305), and then the second bolt (306) is rotated to fix the connecting wire (308 e);

s4, pulling the power connection rod (104), starting a second servo motor (308 b) at the same time, enabling a second rotating shaft (308 c) to rotate, driving a first-stage gear (310 a) to rotate, enabling a second-stage gear (310 b) to rotate, driving a third-stage gear (310 c) to rotate, enabling a reciprocating lead screw (309 b) to rotate, enabling a moving sleeve (309 c) to move up and down, and releasing a connecting wire (308 e);

s5, a user rotates the first bolt (303), then rotates the arc-shaped buckle plate (302) to open the arc-shaped buckle plate, and then the arc-shaped buckle plate (302) is hung and buckled on the cable or the electrical equipment.
