[0013] Technical effects and advantages of the utility model:

[0014] 1. This device can place multiple devices in various places in the plantation by setting the connecting tube and the end part, and then connect the liquid inlet pipe to the output end of the same high-pressure water pump. The high-pressure water pump can pump liquid medicine to multiple devices at the same time. When liquid medicine enters the device, the connecting tube and the end part will be pushed into the working state. When the work is completed, it will automatically drop so that the end part and the connecting tube are stored to prevent insects from entering the end part and the connecting tube, so that the device can have different working modes. When spraying liquid medicine, it can be raised under the push of liquid pressure to spray, which can increase the spraying range of the liquid medicine. It can be automatically stored when not in use to ensure the integrity of the device and prevent clogging by debris; BRIEF DESCRIPTION OF THE DRAWINGS
