Slanted outlet infusion set for trees

The invention discloses a slant-liquid-outlet infusion apparatus for trees. The slant-liquid-outlet infusion apparatus is characterized by comprising a needle head and a pressing plate. A flow passage extending towards the front end is formed in the needle head. The front end of the flow passage is plugged to form a conical head. A slant liquid outlet seam is formed in the side wall of the side, close to the conical head, of the flow passage, wherein a 45-degree included angle is formed between the axis of the flow passage and the slant liquid outlet seam. An annular connector is connected to the back end of the flow passage and internally provided with a platform perpendicular to the flow passage. A hose connector is arranged on the lateral side of the annular connector. The pressing plate is connected to the open side of the annular connector in a sealed mode. Protrusions distributed around a back end opening of the flow passage are arranged on the platform and abut against the inner face of the pressing plate. By means of the slant-liquid-outlet infusion apparatus, fibers of tissues of tree trunks can not be cut off, later-period wound healing and later-period wound growing are facilitated, and a hole can not be plugged; when the slant-liquid-outlet infusion apparatus is used, force can be transmitted to the needle head by pressing the pressing plate through the protrusions, and therefore the needle head can be more easily punctured into the tree trunks.
