Slide grooves are provided at corresponding positions on the two side plates. Bearing seats are slidably installed within the slide grooves, and the same central shaft is fixedly installed on the inner rings of the two bearing seats. A grinding roller is fixedly sleeved on the central shaft. An adjusting spring is also installed between the bearing seats and the bottom inner wall of the slide grooves. A clamp is also slidably installed on the base to fix the washing machine lid. The clamp facilitates the fixing of the washing machine lid and pushes it towards the grinding roller.
