Through the coordinated use of structures such as the base 1, the mixing tank 2, the lifting plate 3, the threaded rod 4, the threaded sleeve 5, the motor 10, the feeding pump 16 and the telescopic rod 20, the use height of the plastering plate 15 can be lifted multiple times when the device is in use, so that it is suitable for interior walls of different heights. At the same time, when the device is not in use, the lifting component can be retracted to reduce the height space it occupies, which is convenient and quick, and avoids the problem of affecting its movement through doors and windows into the room due to the fixed structure of the lifting component, thereby improving the practicality of the device.

[0029] The top of the base 1 and the top of the lifting plate 3 are fixedly connected to a bracket 9, the bottom of the bracket 9 is fixedly installed with a motor 10, the output end of the motor 10 is fixedly connected to a rotating shaft 11, and the transmission assembly includes two pulleys 12, which are respectively fixedly mounted on the outer surface of the threaded rod 4 and the outer surface of the rotating shaft 11, and a belt 13 is connected for transmission between the outer surfaces of the two pulleys 12.
