Description

Technical Field

[0001] The utility model relates to the technical field of tree ring sampling tools, in particular to a growth cone core extraction device. Background Technique

[0002] Due to factors such as the tightness, friction, humidity, and roughness of some tree ring cores, or because the journey from the wild to the laboratory is relatively long and the core cannot be taken out in time, the core is closely attached to the inner wall of the growth cone and is not easy to take out. Or during the extraction process, part of the core breaks and remains inside the growth cone and cannot be taken out. The entire growth cone loses its function and is scrapped, requiring a new purchase, resulting in a relatively high cost.

[0003] Therefore, inventing a growth cone core extraction device can push out the core. First, the core can be taken out completely, saving time and effort, and the taken-out core is complete and the data is accurate. Second, it can be used to remove the broken core, restore the function of the growth cone, and reduce losses. Content of the Utility Model

The connecting rod is movably connected to the side surface of the threaded rod. A limiting plate is fixedly connected to the side surface of the connecting rod. A limiting hole is opened inside the connecting rod. A threaded hole is opened inside the connecting rod. During use, the threaded rod needs to be connected to the inside of the connecting rod through the threaded hole. By rotating the threaded rod, the length of the threaded rod entering the hollow tube can be adjusted, thereby pushing out the tree ring core in the hollow tube, solving the problems that the core cannot be taken out in time, resulting in the core being closely attached to the inner wall of the growth cone and not easy to take out; or during the extraction process, part of the core breaks and remains inside the growth cone and cannot be taken out. The screw can be inserted into the limiting hole to fix the connecting rod in the communicating tube.
