▎ 摘　　要

NOVELTY - The device has a first moving box whose inner part is provided with a first moving rod. A bottom end of the first moving rod passes through the first moving box and extends to an outside of the first moving box. A bottom end of the first moving rod is fixedly connected with a top end of a control box (110.) A surface of a threaded rod (113) is sleeved with a first conical gear (129). A surface of a rotating rod (111) is sleeved with a second conical gear (130). The first conical gear is meshing with the second conical gear. A surface of the first moving box is equipped with an adjusting mechanism. USE - Device for sampling mass of graphene used for manufacturing an electronic component or transistor. Can also be used for a transparent touch screen, a light plate, a solar battery, and a lithium battery. ADVANTAGE - The device can carry out layered sampling and keep the uniformity of graphene slurries of each layer of sampling, avoid the uneven sampling, and ensure better detection effect of the graphite. The device can be inserted into the graphene by rotating the rotating handle by the user to sample the dispersed graphene, so that the graphene can be sucked into the cylindrical liquid pumping box, and the user can take the graphene slurry in the cylinder, for conveniently sampling and detecting the graphene slurry after grinding and crushing. The device improves graphite sampling efficiency of the user, saves the working time of user, ensures better sampling effect, and improves diversity of sampling, sampling effect and sampling accuracy. DESCRIPTION OF DRAWING(S) - The drawing shows a partial sectional view of a graphene mass sampling device. 100Mass sampling device main body 110Control box 111Rotating rod 112Cylindrical liquid pumping box 113Threaded rod 114Pushing block 115First thread groove 116Block 117Box cover 118Inlet 119Blocking plate 120First spring 129First tapered gear 130Second conical gear
