▎ 摘　　要

NOVELTY - The device has a detecting portion that is composed of a first sliding rod (201), a mounting plate (202), an adjusting rod (203), a detecting probe and an elastic sleeve (205). Two first sliding rods are slidingly connected on a mounting arm (104). An adjusting portion is composed of a pushing plate (301), a handle (302), a pushing rod (303), a connecting arm (304) and a driving seat (305). A cleaning portion is composed of a mounting seat (401), a telescopic bottle (402) and a gas spraying pipe (403). The mounting seat is welded on the right end face of the mounting arm. A cleaning portion is composed of a cleaning box portion (501), a sliding seat (502), a second sliding rod (503), an elastic portion (504), a placing plate (505), a cleaning hole (506) and a bump (507). The cleaning box portion is fixedly connected on the top end surface of the base. The cleaning box portion is filled with cleaning liquid. USE - Surface stain fast detecting device for graphene production. ADVANTAGE - The pushing plate solves the problem of the detection probe is easy to be stained with dust after using for a period of time, and at this time, the detection affects the detection result. The device realizes cleaning of the probe for detecting at the same time, and synchronously realizes the cleaning of a fitting. The device reduces the probability of collision of the fixing bolt caused by collision, thus avoiding disassembling of a fixing bolt. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the shaft structure of surface stain fast detecting device for production of graphene. 1Base 2Detecting unit 5Cleaning portion 101Fixing bolt 102Auxiliary groove 104Mounting arm 201First sliding rod 202Mounting plate 203Adjusting rod 205Elastic sleeve 301Pushing plate 302Handle 303Push rod 304Connecting arm 305Driving seat 401Mounting seat 402Telescopic bottle 403Gas injection pipe 501Cleaning box portion 502Sliding seat 503Second sliding rod 504Elastic section 505Placing plate 506Cleaning hole 507Bump
