The mounting block 8 is pushed to release the connection between the mounting block 8 and the limit plate 4, and the placement block 5 is turned downward to make the protective plate 7 parallel to the ground. The mounting block 8 is pushed so that the mounting block 8 is clamped on the outside of the limit plate 4, and the limit screw 9 is turned so that the limit screw 9 is tightly fitted on the upper surface of the mounting block 8. The position of the placement block 5 is fixed, and the telescopic rod 2 is covered by the protective plate 7 and is not located at a protruding position of the device, thereby reducing the probability of collision and damage with other equipment, ensuring the normal use of the telescopic rod 2, and extending its service life.

[0027] A slot 10 is provided on the upper surface of the placement block 5, and the protective plate 7 is clamped in the inside of the slot 10, which is convenient for disassembly and assembly of the protective plate 7. Threaded holes 11 are provided on both sides of the placement block 5, and the threaded holes 11 are the same as the slots 10. A fixing screw 12 is threadedly connected to the inside of each threaded hole 11. Through holes 13 are provided at both ends of the protective plate 7, and the fixing screws 12 are threadedly connected to the inside of the threaded holes 11.

[0030] Working principle:

[0031] In the first step, by setting the protective plate 7 and cooperating with the limit plate 4, when the spraying device is moved, the telescopic rod 2 is placed inside the placement groove 6. After the telescopic rod 2 is placed inside the placement groove 6, the protective plate 7 is clamped inside the clamping groove 10. At this time, the fixing screw 12 is rotated and connected inside the threaded hole 11 and rotated into the inside of the opening 14 and tightly fitted on the outside of the telescopic rod 2. At this time, the telescopic rod 2 is fixed inside the placement groove 6, thereby improving the stability of the fixing of the telescopic rod 2;

[0032] In the second step, turn the limit screw 9 so that the limit screw 9 and the mounting block 8 are no longer in contact. At this time, push the mounting block 8 to release the connection between the mounting block 8 and the limit plate 4. At this time, turn the placement block 5 downward to make the protective plate 7 parallel to the ground. At this time, push the mounting block 8 to make the mounting block 8 clamped on the outside of the limit plate 4. At this time, turn the limit screw 9 so that the limit screw 9 is tightly fitted on the upper surface of the mounting block 8. At this time, the position of the placement block 5 is fixed. At this time, the telescopic rod 2 is covered by the protective plate 7 and is not located in a protruding position of the device, thereby reducing the probability of collision and damage with other equipment and ensuring The telescopic rod 2 is used normally to extend its service life. When the sprayed agricultural products are on the same horizontal line, the limit screw 9 is turned so that the limit screw 9 and the mounting block 8 are no longer in contact. The mounting block 8 is pushed to release the connection between the mounting block 8 and the limit plate 4. The placement block 5 is rotated to adjust the angle of the telescopic rod 2 so that the telescopic rod 2 is in a suitable position. The position of the placement block 5 is fixed again. At this time, the spraying device can be directly pushed to spray the pesticide from the telescopic rod 2. There is no need to push the spraying device while holding the telescopic rod 2 for spraying, which reduces the difficulty of spraying.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
