Quick reversing mechanism for robot

The quick reversing mechanism for the robot comprises a base and a first mounting groove, first fixing seats are fixedly connected to the two sides of the top end of the base, a second fixing seat is fixedly connected to the top end of the base, and a fixing pipe is fixedly connected to the top end in the second fixing seat; and the bottom end of the fixed pipe is fixedly connected with a brush strip. According to the quick reversing mechanism for the robot, by arranging a first mounting groove and other parts, when a driving motor is started and a first bevel gear is driven to rotate leftwards, a third bevel gear can be driven to rotate clockwise, meanwhile, a second bevel gear can be driven to rotate anticlockwise, and at the moment, a first connecting shaft and a second connecting shaft can also rotate along with the first connecting shaft and the second connecting shaft; according to the utility model, the two mechanical arms mounted outside can be driven to change directions, so that not only can the dir
