• a rotary shaft is bridged between the two mounting bases, the rotary base is fixedly connected to the rotary shaft, one end of the wire pole is fixedly connected to the rotary base, the other end of the wire pole is provided with the lamp assembly, and the wire pole and the rotary base have a horizontal state and a vertical state;
• a positioning device for limiting the wire pole in the vertical state is provided on the top portion of the carriage, and the positioning device comprises a first positioning unit and a second positioning unit;
• the rotary base has a first positioning surface and a second positioning surface;
• the first positioning unit comprises a first limiting platform, which is located at one side of the rotary shaft and has a side abutting against the first positioning surface of the rotary base when the rotary base is in the vertical state;
• the second positioning unit is located at the other side of the rotary shaft, and the second positioning unit comprises a mounting slot arranged in the top portion of the carriage, wherein a rotation limiting plate that is rotatable in a vertical plane is mounted in the mounting slot, a torsion spring is connected to a rotary connecting part of the rotation limiting plate inside the mounting slot, and the rotation limiting plate always abuts against the second positioning surface of the rotary base under an action of the torsion spring;
• two positioning plates that are telescopically movable are respectively provided on two opposite side walls of the mounting slot, and the two positioning plates are movable towards or against each other synchronously, and the two positioning plates extend out and support a lower end surface of the rotation limiting plate when the rotation limiting plate rotates to a vertical state;
• the utility vehicle for power emergency repair further comprising a driving assembly for driving the rotary shaft to rotate, wherein an end of one of the positioning plates is provided with a first contact, an end of the other one of the positioning plates is provided with a second contact, and the first contact and the second contact is contactable to generate a trigger signal and control the driving assembly to release braking on the rotary shaft.
