▎ 摘　　要

NOVELTY - The cup has a supporting plate (1) whose right side fixedly connected with a fixing block is provided with a double-face rack. The right sides of the front face and the back face of the double face rack are provided with rotating shafts. The top and the bottom of the rotating shaft are connected with bearings. The bearing is connected with the inner wall of a sleeve (2) far away from the dual face rack. The right side of a connecting plate is connected to an arc-shaped plate (14). A top portion of the supporting plate is equipped with a material-tapping cup main body (15). The surface of the material-taking cup main portion is connected and matched with the inside of the arc plate. USE - Portable material taking cup for detecting in graphene preparation process. Uses include but are not limited to notebook computer, intelligent mobile phone, LED display screen and marine anti-corrosion. ADVANTAGE - The cup can reduce friction of the movable plate and the sleeve by matching use of the sliding block and the sliding groove, thus prolonging service life of the plate. The cup is easy to carry, improves practicability of the cup, and is convenient for a user to use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an application of portable material taking cup for detecting in graphene preparation process. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a portable material taking cup for detecting in graphene preparation process. upporting plate (1) leeve (2) Arc-shaped plate (14) Material-tapping cup main body (15) Plate (17)
