When the snap connection is connected, the snap block is subjected to the action of an external force. While moving inside the slot, the latching teeth and the latching teeth mounting plate are subjected to the extrusion force from the snapping block and begin to move to the opposite side. The spring sheet is subjected to the extrusion force from the latching teeth and is elastically stretched, thereby achieving the adjustment effect on the snapping block in turn. After the snapping block is fixed, the spring sheet, the latching teeth mounting plate and the latching teeth all lose the extrusion force. Under the rebound effect of the spring sheet, the latching teeth on one side of the latching teeth mounting plate are snapped with the latching teeth on the outer side of the snapping block, thereby achieving the fixing effect of the snapping block.

The second medicine delivery pipeline is made of elastic material, so that the length of the second medicine delivery pipeline can be adjusted. When it is necessary to spray medicine on the gaps between the leaves, the spray nozzle can be inserted between the trees for spraying by extending and retracting the length of the second medicine delivery pipeline and the second electric telescopic rod.

[0017] The present invention has at least the following beneficial effects:

When in use, the medicine storage box is placed on the inner side of the mounting mechanism, and the sliding seat at one end of the mounting mechanism is clamped into the clamping groove symmetrically provided inside the mounting base by a clamping connection. When the clamping block is subjected to external force, the medicine storage box is fixed to the mounting mechanism.
