The middle part of the top of the two support platforms is fixedly provided with a mounting block, the middle part of one of the mounting blocks is fixedly provided with an electric cylinder, and the telescopic end of the electric cylinder is fixedly connected to one end of the other mounting block. The beneficial effects of the utility model are: in order to facilitate the smoothing of cement at the joint and improve the flatness of the joint, the transmission shaft of the servo motor drives the screw rod to perform synchronous The screw rod drives the trowel plate to move synchronously through the slider to perform the trowel operation. The servo motor is controlled to rotate forward and reverse to control the left and right movement direction of the trowel plate. It is more convenient for workers to use, and it also reduces the labor of workers and improves work efficiency.
