AI Technical Summary
Existing growth cone samplers lack a fixing device, which makes them prone to tilting when drilling into trees, potentially injuring operators and making it difficult to accurately determine the sampling depth.
The system employs a fixed component and a sampling component, including a connecting plate, a lead screw, a movable plate, and a sleeve. The sampling component is fixed by the sliding structure of the lead screw and the cooperation of the movable plate. Combined with a level and graduation lines, this ensures accurate and deviation-free sampling.
This achieves stable fixation of the sampler, prevents slippage, ensures accurate sampling depth, reduces the risk of injury to operators, and improves sampling efficiency and accuracy.
