When attaching the injection assisting tool 4 of the fourth embodiment to the injection part of the trigger type liquid injector, the mounting part 31 of the injection auxiliary tool 4 is externally fitted to the injection part from the front direction as in the third embodiment. . Since the convex part of the injection part and the U-shaped cutout part 32a of the mounting part 31 are engaged with each other, the mounting part 31 is firmly fitted to the injection part 71, and the mounting part 31 does not fall off the injection part. When the mounting portion 31 is fitted into the injection portion, the rod-like main body portion 45 extends above the horizontal plane including the injection central axis of the injection region and extends in the injection direction.

<Explanation of usage>
Therefore, when the tip of the injection assisting tool 4 is inserted into the back side of the leaf and the tip is moved upward with the wrist as a fulcrum, the leaf can be turned, and the back of the leaf is placed in front of the injection region. Can be positioned. When the operation lever is operated in this state and the chemical solution is ejected from the ejection port, the drug can be accurately ejected and diffused on the back of the leaf. Further, since the injection port is separated from the back of the leaf by at least the length of the rod-shaped main body 45, the injected chemical is sufficiently spread, and the chemical can be efficiently injected over a wide area of the back of the leaf.

  According to the injection assisting tool 4 of the fourth embodiment, the main body portion can be formed in a small diameter, so that it is difficult to obstruct the injection region formation. Further, since the diameter is small, the visibility of the back surface 83 of the leaf 81 does not deteriorate. Further, it is possible to manufacture a lightweight and inexpensive main body.
