[0032] Referring to Figures 2-4 The upper right side of processing table 1 is provided with rotating rod 6, the upper surface of rotating rod 6 is fixedly connected with elastic element 7, elastic element 7 includes rectangular telescopic rod and spring, rectangular telescopic rod is fixedly connected on the upper surface of rotating rod 6, spring is sleeved on the outside of rectangular telescopic rod, when the upper end of rectangular telescopic rod rotates, it can drive its lower end to rotate synchronously, without appearing separation movement, so that when elastic element 7 rotates, it can drive rotating rod 6 below to rotate synchronously, after the upper end of elastic element 7 is limited, rotating rod 6 moves up to extrude elastic element 7, so that elastic element 7 generates elastic potential energy when being compressed.

[0033] The upper side of rotating rod 6 is provided with driving unit, driving unit includes cleaning frame 61, cleaning frame 61 is fixedly connected on the upper surface right side of processing table 1, cleaning frame 61 can provide installation movement position for the component provided, the inside top surface of cleaning frame 61 is fixedly connected with electric push rod 62, the bottom end of electric push rod 62 is fixedly connected with cleaning motor 63, when electric push rod 62 starts, it can drive cleaning motor 63 to move linearly in up-down direction, the bottom output end of cleaning motor 63 is fixedly connected with the upper end of elastic element 7, when cleaning motor 63 starts, it can drive elastic element 7 to rotate, when electric push rod 62 starts and drives cleaning motor 63 to move in up-down direction, it can drive rotating rod 6 to move synchronously through elastic element 7, and when cleaning motor 63 starts, it can also drive rotating rod 6 to rotate through elastic element 7.
