Description

Technical Field

[0001] The utility model relates to the technical field of tree rodent-proofing devices, in particular to a telescopic rodent-proofing device for planting pine trees. Background Art

[0002] Pine is an evergreen coniferous tree of the genus Pinus in the Pinaceae family. It is a very common tree. After planting, pine trees are easily attacked by rodents. The harm caused by rodents to plants such as trees and seedlings mainly lies in that they gnaw on the lower bark and stems of pine trees, destroying the nutrient transport tissue of pine trees, causing the pine trees to be unable to absorb nutrients in the soil and wither and die. Sometimes they directly bite off the stems of seedlings, causing economic losses to pine tree planting.

[0003] A Chinese patent with publication number CN205611412U discloses a telescopic rodent-proof device for trees, comprising a rodent-proof enclosure with open top and bottom, wherein the rodent-proof enclosure comprises two baffle assemblies disposed on both sides and two connecting assemblies detachably connected between corresponding ends of the baffle assemblies on both sides.

[0004] The telescopic rodent-proof device for trees described above can change the size of the enclosed space and is suitable for use on trees of different diameters. It has strong applicability. However, when adjusting, the fixed columns on the four sides of the device slide in the sliding grooves of the sliding strip to change the size of the enclosed space, and then the device is fixed by tightening the fastening nuts. The sliding positions of the fixed columns need to be manually controlled, and it is difficult to ensure that the sliding positions of the four groups of fixed columns are the same, and further it is difficult to ensure that the enclosed space of the device is proportionally expanded or reduced. The device does not fit the tree well enough, and the device is fixed only by the friction between a single fastening nut and the sliding strip. It is easy to loosen and has average firmness. Therefore, it is urgently needed to be improved. Utility Model Content
