When the slider 5 is released, the push rod 9 causes the block 10 to engage with the slot outside the limiting disc 11 under the elastic force of the reset spring 17, thereby realizing the limiting locking function of the upper rotating ear 16 relative to the lower rotating ear 15, thereby realizing the rapid fixing function of the high-altitude live insulating spray rod after the angle is adjusted.

[0028] A pin groove is provided inside the limiting disc 11, and the pin groove is engaged with the pin key outside the rotating shaft 12. The rotating shaft 12 passes through the lower rotating ear 15 and is rotatably connected with the lower rotating ear 15. The rotating shaft 12 passes through the upper rotating ear 16 and is fixedly connected with the upper rotating ear 16. The limiting disc 11 is arranged between the two groups of lower rotating ears 15. The limiting disc 11 is arranged between the two groups of upper rotating ears 16. The upper rotating ear 16 is fixedly connected to the insulating spray rod body 2. The push rod 9 passes through the lower rotating frame 14. A reset spring 17 is provided outside the push rod 9. One end of the reset spring 17 is fixedly connected to the upper end of the push rod 9. The reset spring 17 The other end is provided with a mounting cover 13, the mounting cover 13 is bolted to the bottom of the lower rotating frame 14, the mounting cover 13 is slidably connected to the push rod 9, the bottom of the lower rotating frame 14 is fixedly connected with a connecting frame 18, the connecting frame 18 is fixedly connected with a fixed support rod 19, the outside of the steel rope 6 is provided with a shell 7, the inside of the grip 3 is provided with an operating handle 20, by setting the fixed support rod 19, since an adjusting nut is provided in the middle of the fixed support rod 19, the telescopic length of the fixed support rod 19 can be quickly adjusted by adjusting the nut, thereby realizing the rapid adjustment of the height of the high-altitude live insulating spray boom.

[0029] Working principle: First, adjust the nut in the middle of the fixed support rod 19, and then quickly adjust the height of the fixed support rod 19, so as to adjust the height of the insulating spray rod body 2. Then, by pressing the slider 5, the slider 5 will squeeze the steel rope 6, and the steel rope 6 will slide inside the shell 7, so as to realize the function of contracting the other end of the steel rope 6. Since one end of the steel rope 6 is fixedly connected to the lower pull ear 8, the lower pull ear 8 drives the block 10 through the push rod 9 to overcome the elastic force of the reset spring 17 and move away from the card slot outside the limiting disc 11.

The ear 16 has the function of freely rotating relative to the lower rotating ear 15. Since the upper rotating ear 16 is fixedly connected to the insulating spray rod body 2, at this time, only the insulating spray rod body 2 needs to be held to realize the rapid adjustment of the inclination angle of the insulating spray rod body 2. The fixed support of the fixed support rod 19 effectively reduces the operational burden of workers maintaining the same spraying posture for a long time, and the angle of the insulating spray rod body 2 is quickly adjusted, thereby effectively ensuring the spraying quality. After releasing the slider 5, the push rod 9 will push the block 10 to engage with the card slot outside the limit disc 11 under the elastic force of the reset spring 17, thereby realizing the locking function of the upper rotating ear 16 relative to the lower rotating ear 15, thereby realizing the fixing function of the insulating spray rod body 2.
