PRESSURE TYPE INJECTOR FOR A SHAFT OF TRESS

摘要

Provided is a pressure-type injector for the shaft of trees to prevent the leakage of chemicals contained in an injector effectively and to allow the chemicals to be injected rapidly. The pressure-type injector for the shaft of trees comprises a container main body(100) comprises an inner wall(110) and an outer wall(120) provided with a plurality of hooking grooves providing a space part between them, and a front discharge hole blocked with a blocking wall(130); a compression container(200) which is provided with a hooking projection hooked by the each hooking groove formed at the outer surface of a side wall and is to be inserted into the space part to compress the internal pressure of the container; and an injection pipe(300) which is provided with an insertion part(310) at the back surface of a direction display flange(320) so as to allow it to penetrate the blocking wall and be inserted into the discharge hole, wherein the compression container has a supporting wall(220) provided with a guide part(201) at the outer part of the side wall(210) so as to allow the outer wall(120) of the container main body to be inserted.
