When the fourth inner cavity 813 moves, it drives the limiting rod 815 to slide inside the limiting groove 814. The groove surface of the limiting groove 814 is a gradient surface, which is convenient for the limiting rod 815 to slide inside the limiting groove 814.

[0047] The fan 53 is provided to blow air into the back barrel 51, so that the wind enters the inside of the air hole from the bellows 4, and the wind squeezes the bottom plate 55. At the same time, the telescopic cylinder 54 is contracted, and in the process of the telescopic cylinder 54 moving upward and contracting, the bottom plate 55 drives the telescopic block 510 to move, and the telescopic block 510 slides over the surface of the first clamping block 59. When the telescopic block 510 slides over the surface of the first clamping block 59, the telescopic block 510 contracts. After the telescopic block 510 slides over the first clamping block 59, the first clamping block 59 below the telescopic block 510 supports the telescopic block 510, and the telescopic block 510 cannot move downward. The upper surface of the telescopic block 510 is an inclined surface , the lower surface of the first clamping block 59 is an inclined surface; when the telescopic cylinder 54 moves to the maximum position, the top cover 513 is opened, and insulating paint is added to the inside of the telescopic cylinder 54; before adding the insulating paint, the adjusting rod 56 is moved, and the adjusting rod 56 drives the slide plate 58 to move, and the movement of the slide plate 58 drives the first clamping block 59 to move. After the first clamping block 59 moves, the first clamping plate and the telescopic block 510 are separated. At this time, the bottom plate 55 drives the telescopic cylinder 54 to reset downward; the telescopic cylinder 54 is lifted upward by the cooperation between the first clamping block 59 and the telescopic block 510, which is convenient for cooperating with the nozzle 1 to spray the insulating paint, and the spraying process is stable and the effect is excellent.

[0048] When the present invention is in use, when standing on the ground and no adjustment is needed for the length of the nozzle 1, when the telescopic rod 2 is extended, when the telescopic rod 2 is retracted inside the stabilizing rod 3, the telescopic rod 2 will drive the card slot 61 to move above the locking block 71, the card slot 61 will squeeze the locking block 71, the locking block 71 will enter the inside of the card slot 61, and when the wind enters the second connecting hole 72, the locking block 71 will be lifted up, and the locking block 71 will be lifted up so that the second connecting hole 72 is connected to the air inlet 16; when the locking block 71 moves downward, the moving block will abut against the top of the squeezing rod 79, the squeezing rod 79 rotates at the end of the second slide bar 78, and the squeezing rod 79 moves downward, and during the movement of the squeezing rod 79, the second slide bar 78 is driven to move inside the first slide slot 77. The locking mechanism 7 is provided to facilitate the connection of the retracted telescopic rod 2 and the stabilizing rod 3, and when spraying the paint, the telescopic rod 2 and the stabilizing rod 3 will not move, and the telescopic rod 2 and the stabilizing rod 3 that are easy to adjust can still maintain the function of spraying the insulating paint. When the second sliding rod 78 slides, it pulls the moving rod 81 to move, and the movement of the moving rod 81 drives the fourth inner cavity 813 to move. When the fourth inner cavity 813 moves, it drives the limiting rod 815 to slide inside the limiting groove 814. The groove surface of the limiting groove 814 is a gradient surface, which is convenient for the limiting rod 815 to slide inside the limiting groove 814. When the moving rod 81 pulls the limiting rod 815 to move, the limiting rod 815 drives the inner rod 84 to move, and then the pull rod 86 drives the blocking block 89 to move, and the blocking block 89 moves from the inside of the blocking groove 810; at the same time, the guide rod 88 slides inside the guide groove 87, and the cooperation of the guide rod 88 and the guide groove 87 enables the lateral movement of the inner rod 84 to enable the blocking block 89 to move up and down. The fan 53 blows air to the interior of the back barrel 51, so that the wind enters the interior of the air hole from the bellows 4, and the wind will squeeze the bottom plate 55. At the same time, the telescopic tube 54 is contracted, and in the process of the telescopic tube 54 moving upward and telescoping, the bottom plate 55 drives the telescopic block 510 to move, and the telescopic block 510 slides over the surface of the first block 59. When the telescopic block 510 slides over the surface of the first block 59, the telescopic block 510 contracts. After the telescopic block 510 slides over the first block 59, the first block 59 below the telescopic block 510 supports the telescopic block 510, and the telescopic block 510 cannot move downward; the cooperation between the first block 59 and the telescopic block 510 realizes the upward lifting of the telescopic tube 54, which is convenient for cooperating with the nozzle 1 to spray the insulating paint, and the spraying process is stable and the effect is excellent. When the position of the nozzle 1 needs to be extended, the telescopic rod 2 is pulled to extend, and the telescopic rod 2 drives the slot 61 to move, and the slot 61 will be squeezed on the top of the second block 62 until the second block 62 enters the inside of the slot 61. When the wind force enters the inside of the first connecting hole 63 from the wind hole opened in the stabilizing rod 3, the wind force is finally discharged from the air outlet 12.When the wind enters the lower part of the second block 62, the wind will squeeze the second block 62, and the second block 62 will be squeezed into the inside of the slot 61. The second block 62 makes the telescopic rod 2 and the stabilizing rod 3 more tightly engaged. After the first connecting hole 63 is connected, the second block 62 always remains engaged. The wind discharged from the air outlet 12 forms a negative pressure through the paint port 15, so that the paint inside the injection port 13 enters the injection port 13, and the paint is discharged from the spray port 11; the telescopic rod 2 will squeeze the connecting mechanism 6 during its movement, and the connecting mechanism 6 will move to connect with the air inlet 16, so that the wind can be discharged from the connecting mechanism 6 and finally discharged through the air outlet 12, and at the same time, negative pressure is generated at the air outlet 12, and the paint is discharged at the same time.
