PRESSURE TYPE INJECTOR FOR A STEM

摘要

PURPOSE: A pressure type trunk injector is provided to facilitate insertion into a punched hole of a tree without using a separate tool by forming an insertion guide that is formed of a protrusion part with a spiral shape on the outside of an inlet port of a body container. CONSTITUTION: A pressure type trunk injector comprises a space unit(11) which accommodates a drug therein; an injection inlet(12) which is blocked by a barrier membrane(13) at a lower part of the space unit; an insertion guide(14) which is formed to protrude in a spiral shape along the peripheral of the outside of the injection inlet to facilitate insertion; an inlet unit(15) which includes multiple injection grooves(16) at an end part of the injection inlet; a body container(10) which includes a holding unit(17) that is formed to sharply protrude from an inner wall of the space unit that is connected from the space unit to the injection inlet; a push unit(21) which has an arc shape to protrude upwardly to a top to give pressure to the space unit; a connection rod(22) which is accommodated in the space unit of the body container, for which the outside of the connection rod has a saw tooth shape; a pressure injector(20) which includes a guide part(23) having a structure of which the end part is cut in slash in order to inject drug into a tree.
