Mechanical retaining mechanism of scraper holder

The utility model discloses a mechanical retaining mechanism of a scraper holder, which comprises a scraper holder arranged between wallboards, a net wire roller associated with the scraper holder, two ends of the net wire roller are movably mounted between the wallboards through retaining mechanisms respectively, and each retaining mechanism comprises a driving part, a stop block and a limiting component. The stopping block is connected to the driving part, the limiting assembly is associated with the stopping block so that the limiting assembly can be limited by the stopping block, and the limiting assembly is connected to the cable roller in a sleeving mode; the cable roller is fixed between the wall plates through the retaining mechanism, and the retaining mechanism can be driven by the driving part to enable the cable roller to be conveniently taken out, so that the dismounting difficulty of the cable roller is reduced, and the later maintenance efficiency of the cable roller is improved. 本实用新型公开了一种刮刀架机械
