[0002] Litter collection in valley forests typically employs litter collectors or ground sampling methods, placed at a certain height above the ground to avoid soil disturbance. Leaves and branches are collected periodically and separately. The collected litter is dried and weighed for analysis of nutrient content and decomposition rate. This data helps assess the forest ecosystem's carbon sequestration capacity, nutrient cycling status, and ecological restoration effectiveness.

[0003] 1. River valley forests are prone to flooding in spring and summer, and traditional litter collection devices are susceptible to sample flooding and device displacement. Flooded samples can negatively impact the final assessment data, hindering accurate evaluation of the forest ecosystem; device displacement also increases the time spent by personnel searching for the device.

[0004] 2. In existing technologies, the size of some collection devices is fixed and cannot be adjusted arbitrarily according to different usage scenarios. This makes the collection devices unable to meet actual usage needs. Utility Model Content

A first lock bar 24 corresponds to a first lock hole 26. A second lock bar 28 corresponds to a second lock hole 210.

[0031] The above structure includes a first fixed frame 23, with a first locking rod 24 threadedly connected to the top of the first fixed frame 23. A first sliding rod 25 is slidably connected inside the first fixed frame 23, and a first locking hole 26 is provided above the first sliding rod 25. This allows the operator to loosen the first locking rod 24, extending it from the first locking hole 26. The operator can then pull the first sliding rod 25 to adjust the distance in the front-back direction of the adjusting device 2, i.e., the size of the adjusting device 2.

[0032] A second fixed frame 27 is provided, with a second locking rod 28 threadedly connected to the top of the second fixed frame 27. A second sliding rod 29 is slidably connected inside the second fixed frame 27, and a second locking hole 210 is provided above the second sliding rod 29. This allows the operator to loosen the second locking rod 28 and remove it from the second locking hole 210.
