[0029] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation methods, structures, features and effects of the utility model application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0030] like Figures 1 to 4 As shown, an embodiment of the utility model proposes an apparatus for weighing powder samples to be transferred, comprising: a main body 1, a copper foil 2, a support body 3 and a connecting part 5; the main body 1 is preferably made of plastic material, which is light in weight and low in cost. The main body 1 has a groove structure 1-1; one end of the groove structure 1-1 has a barrier part 4 extending upward; the barrier part 4 is located at the rear end of the groove structure 1-1, so that the front end of the groove structure 1-1 can shovel in the material, and the rear end is blocked, and the material remains in the groove structure 1-1. The distance between the outer walls on both sides of the groove structure 1-1 gradually increases from bottom to top to facilitate the operator's hand-held operation and prevent the main body 1 from falling off the operator's hand. The copper foil 2 is attached to the inner wall of the main body 1; the support body 3 is a strip-shaped structure; the support body 3 is embedded in the bottom of the main body 1; the lower end surface of the support body 3 is raised relative to the lower end surface of the main body 1 to support the main body 1; the support body 3 is a conductor; there are two support bodies 3; the two support bodies 3 are arranged parallel to each other; the connecting part 5 is connected to the copper foil 2 and the support body 3 respectively; the connecting part 5 is a conductor; so that the copper foil 2 and the support body 3 are conductive. It is necessary to transfer the powder sample into the groove structure 1-1, conduct the static electricity to the connecting part 5 and the support body 3 through the copper foil 2, and then conduct it to the grounded weighing tool such as the balance through the support body 3 to realize the static electricity release in the powder sample.
