Fixing device of tree infusion syringe needle

Abstract

The present invention discloses a fixing device for a tree infusion syringe needle and relates to the field of tree infusion. The fixing device for the tree infusion syringe needle comprises a tree infusion hole and a threaded column in threaded connection with the infusion hole, and the threaded column is provided with an inner hole penetrating through an upper end face and a lower end face; an infusion needle has the same diameter as the inner hole and a side surface is provided with at least one contraction grooves; clamping grooves corresponding to the contraction grooves are arranged in an inner side wall of the inner hole; clamping parts are fixed in the contraction grooves, driving parts are located at end parts of the infusion needle and the driving parts and the clamping parts arein power connection; and during use, the threaded column is firstly combined with the infusion hole, then before the infusion needle inserts the inner hole, the driving parts enable the clamping parts to be completely contracted into the contraction grooves, after the infusion needle inserts the inner hole, the driving parts enable one ends of the clamping parts to extend into the corresponding clamping grooves, so that the clamping parts can fix the infusion needle in the inner hole, and the infusion needle is guaranteed to conduct stable tree infusion when natural environment is bad.

Description

technical field [0001] The invention relates to the field of tree infusion, in particular to a fixing device for tree infusion needles. Background technique [0002] At present, along with people's emphasis on improving the ecological environment, there are more and more phenomena of transplanting larger trees for urban greening. But the bigger the tree, the less likely it will survive transplantation. Practice has proved that in the process of transplanting larger trees, infusion of large trees is a better method to ensure the survival of transplanting. [0003] The applicant found that: because the trees grow in the natural environment, if the natural environment is harsh during infusion, such as in a windy and rainy environment, the infusion needle is easy to fall from the infusion hole of the tree, which has caused the The waste of liquid also delays the infusion time of trees. Contents of the invention [0004] In view of this, the object of the present invention i...

Problems solved by technology

[0004] In view of this, the object of the present invention is to propose a fixing device for tree infusion needles to solve the problem in the prior art that because trees grow in a natural environment, during infusion, if the natural environment is harsh, the infusion needle is easy to fall from the tree. The hole falls, which not only causes a waste of liquid medicine, but also delays the technical problem of the tree's infusion time
