Description

Technical Field

[0001] This application relates to the field of tree pest control, and particularly to a tree pest control device. Background Art

[0002] Trees refer to plants with woody stems, usually tall and perennial. They generally have a main trunk and branches, forming a crown. There are some bugs in the natural environment that feed on the leaves and bark of trees. To protect the health and growth of trees, pest control treatment needs to be carried out on the trees. By hanging a device for trapping pests on the trees, the number of pests on the tree surface can be reduced to achieve the pest control effect.

[0003] Existing pest trapping devices are generally hung on the branches of trees. However, since many branches of trees generally grow obliquely, the trapping device hung on the branch may slide downwards, and the wind force in the natural environment will drive the movement of the tree branches. When the wind force is large, it may blow the branches and cause the trapping device to fall to the ground, thereby affecting the overall use efficiency of the trapping device and having a certain impact on the overall pest prevention effect of the trees.

[0004] Regarding the above related technologies, the inventor believes that the trapping device hung on the tree branch has the defect of falling off the branch under the influence of wind force. Therefore, a tree pest control device is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the problem that the trapping device hung on the tree branch falls off the branch under the influence of wind force, this application provides a tree pest control device.

[0006] The tree pest control device provided by this application adopts the following technical solution:

[0007] The tree pest control device includes a trapping device. In the middle of the top end of the trapping device, a hook is fixedly installed. In the middle of the bottom end of the trapping device, a fixed shaft is fixedly connected. An activity support plate is sleeved on the outer surface of the fixed shaft. A support rod is rotatably installed at one side edge of the activity support plate. A limit screw is installed in the middle of the top end of the support rod. A connection frame is rotatably installed at the top end of the limit screw. A binding band is fixedly installed on the inner top of the connection frame. A fixing hole is penetrated and opened at one side edge of the connection frame. One side edge of the binding band passes through the outside of the fixing hole. A fastening bolt is threadedly connected to the outer surface of the connection frame near the fixing hole. One side of the fastening bolt extends into the fixing hole and rotatably installs a fastening block. A limit mechanism is also provided on the outer surface of the hook for hanging the trapping device on the oblique branch.

[0008] Preferably, the limiting mechanism includes a movable collar which is movably sleeved on the outer surface of the hook. One end of the movable collar is rotatably installed with a movable frame. Inside the movable frame, guide rods are symmetrically and fixedly installed. The outer surface of the guide rod is sleeved with a movable block. The top of the movable block is welded with a first clamping block, and a second clamping block is movably installed above the first clamping block.

[0009] Preferably, fixing grooves are symmetrically formed at the top edge of the first clamping block. The bottom edge of the second clamping block extends into the fixing groove and is welded with a T-shaped connecting rod. A spring is sleeved on the outer surface of the T-shaped connecting rod inside the fixing groove.

[0010] Preferably, a threaded groove is formed in the middle of the top of the support rod. The bottom of the limit screw is located inside the threaded groove, and the limit screw and the threaded groove are mutually adapted.

[0011] Preferably, a through hole is formed through the middle of one side of the movable block. The outer diameter of the guide rod is smaller than the inner diameter of the through hole, and the guide rod and the through hole are mutually fitted.
