5. An insulating stay for live working with a vertical rod according to claim 4, wherein the bottom of the clamping post (113) is in a quarter sphere shape.
6. The application method of the insulating stay bar for the live-line vertical withdrawal rod operation is characterized by being applied to the insulating stay bar for the live-line vertical withdrawal rod operation, and comprises the following steps of:
s1: before live-line vertical rod withdrawing operation is carried out, firstly, three insulating support rods (1) are assembled, one end of a movable support rod (102) is inserted into a clamping sleeve (4), one end of the movable support rod (102) extrudes a clamping column (113) to enable the clamping column (113) to be extruded into a positioning annular groove (10), the clamping column (113) extrudes a spring (112) to enable the spring (112) to have elasticity, meanwhile, the movable support rod (102) drives an inserting rod (9) to slide in an inserting groove (8), and the inserting rod (9) drives two sliding blocks (91) to slide in a strip-shaped sliding groove (82) to enable the sliding blocks (91) to move into a limiting annular groove (81);
s2: at the moment, the movable supporting rod (102) is rotated, the movable supporting rod (102) drives the sliding block (91) to rotate in the slot (8) through the inserting rod (9), so that the sliding block (91) is staggered with the strip-shaped sliding groove (82), the sliding block cannot move to two sides in the limiting annular groove (81) and can only rotate, meanwhile, the movable supporting rod (102) rotates to drive the position of the rectangular inserting hole (11) to change, when the rectangular inserting hole (11) is matched with the clamping column (113), the clamping column (113) is downwards inserted into the rectangular inserting hole (11) through the elasticity of the spring (112), and one side plane of the bottom of the clamping column (113) abuts against one side inner wall of the rectangular inserting hole (11), so that the movable supporting rod (102) can be fixed in the clamping sleeve (4) and cannot rotate;
s3: the three insulating supporting rods (1) are operated according to the steps S1 and S2, the three insulating supporting rods (1) are distributed in a triangular shape, then phase-change wires are placed between a fixed fastener (71) and a movable fastener (72) in a rotary fastener mechanism (7), bolts (74) are connected in two threaded holes (73) in a threaded mode, the movable fastener (72) and the fixed fastener (71) move towards the directions close to each other, the wires are fixed, and the wires can be unfolded and fixed, so that the safe distance is achieved.
