A punching sampling device is required during the cutting process. Upon inquiry, the utility model with announcement number CN203414298U discloses a sampler for detecting the weight of tobacco leaves, including a movable circular cutter and a base, one end of the movable circular cutter is rotatably connected to the base, the movable circular cutter includes a handle and a circular cutter connected to one end of the handle, the circular cutter is a hollow circular cutter with an upper end sealed, the circular cutter is equipped with a spring and a cylindrical pressure block connected to the spring, and a circular anvil is provided on the base corresponding to the circular cutter, and the inner diameter of the circular cutter is the same as the diameter of the circular anvil.
