Abstract

The invention discloses a wood sampler. The wood sampler comprises an electric hand drill, a drill bit, a sample collector and a telescoping mechanism, wherein the drill bit is mounted at a chuck of the electric hand drill; the telescoping mechanism comprises a barrel, the rear end of the barrel is detachably connected with the front end of the electric hand drill, and the sample collector is nested in the barrel and is in sliding fit with the barrel; the drill bit is located on the axis of the barrel and the sample collector; a spiral spring of the telescoping mechanism is located between the sample collector and the electric hand drill. According to the technical scheme of the wood sampler, the rear end of the barrel of the telescoping mechanism is detachably connected with the front end of the electric hand drill, the sample collector is nested in the barrel and is in sliding fit with the barrel, the drill bit is located on the axis of the barrel and the sample collector, and the spiral spring of the telescoping mechanism is located between the sample collector and the electric hand drill, so that the defect of proneness of the conventional wood sampler to sample pollution is overcome.

Description
