[0002] A suspended high-pressure cleaner is a compact high-pressure cleaner. In order to reduce the size of this type of high-pressure cleaner, the high-pressure pump is suspended on the end cover, that is, one end of the end cover is connected to the motor and the other end is connected to the high-pressure pump. In addition to being connected to the end cover, the high-pressure pump is not connected to other parts of the cleaner. When in use, the end cover needs to withstand all the forces generated by the high-pressure pump, especially the radial force generated by the vibration of the high-pressure pump. However, the existing end cover structure is not strong enough and is easily deformed during long-term use, resulting in shortcomings such as loud noise and unstable transmission. In severe cases, it may even cause operating failures and equipment damage. Utility Model Content
