When the grinding discs 7 move to the upper and lower sides of the plywood, the rotation of the first motor 3 is stopped. When the output shaft of the first motor 3 rotates clockwise, the two movable plates 5 are driven to approach each other. When the output shaft of the first motor 3 rotates counterclockwise, the two movable plates 5 are driven to move away from each other. One side of the output shaft of the two first motors 3 is fixedly connected to a screw rod 4, and the two screw rods The outer surface of 4 is threadedly connected to two movable plates 5, and one side of the two movable plates 5 is fixedly connected to a second motor 6.
