The utility model provides a tree pine wood nematode detection sampler. The tree pine wood nematode detection sampler comprises an adjusting box, a first threaded rod is arranged in the adjusting box, one end of the first threaded rod is connected with a first hand wheel, two sets of first connecting sleeves are symmetrically arranged on the first threaded rod, and the two sets of first connecting sleeves are both connected with the lower end of a fixed clamping block; when the tree pine wood nematode detection sampler starts to be used, a first threaded rod can be driven to start to rotate by shaking a first hand-cranking wheel, and due to the fact that opposite threads are arranged on the two sides of the first threaded rod, and in addition, corresponding threads are arranged on the inner walls of the two sets of first connecting sleeves, the sampling accuracy is improved. At the moment, the two groups of fixed clamping blocks start to move relatively close to each other under the action of the two groups o
