Specifically, the positioning portion 236 can be a groove, and the swinging seat is formed with a corresponding convex block 237, and the protruding portion 237 can be engaged with one of the positioning portions US. The swing seat 235 is positioned against the positioning portion 236. 7 rotating the month 'Fig. 1 and Fig. 2 'The power unit 3 is provided in the casing 1 ' The composite lifting sill 2 is rotatably provided in the power unit 3 'the power unit 3 for receiving the outside ten The composite rotating shaft base 2 can be rotated around the revolution shaft, and the power unit 3 is actually set as a pneumatic motor in the embodiment, wherein the utility device can be connected to the high-pressure gas source via the switch U. For opening and opening, the high-view body is input, the blade is rotated, and the step-by-step driving is performed. In other possible embodiments of the present creation, the moving part 3 may also be actually set to utilize electric power. The operating motor is configured to drive electric power through the switch to drive the composite rotating shaft base 2 to rotate. The polishing sheet 4 is detachably provided on the rotating base 22, so that the polishing piece 4 can be rotated about the rotation of the rotating base 22 and can be rotated with the gyro 22 around the revolution axis, and is the same as the rotating base 22, Compound rotation mode. In the above-mentioned user's desire to use the grinder of the present invention, the grip can be gripped and the switch can be turned on. The power section then drives the compound rotary nut 2 to rotate around the revolution axis, thereby driving the grinding 4 to rotate the shaft, #磨片When contacting the workpiece to be processed, 'grinding# and rotating can be rotated by the frictional force, so that the grinding piece can perform more complicated rotation. Among them, 'When the use time is long, the abrasive sheet 4 may need to be replaced due to wear'. At this time, if the replaced abrasive sheet 4 is different from the original intended use of the abrasive sheet, the composite disc will be rotated due to the change in the quality of the abrasive sheet. The center of the shaft and the center of the grinding disc are deviated from the common, and the composite will be shocked when the male lion is circling. To avoid or reduce the vibration, the adjusting mechanism can be used to change the moment of inertia of the adjusting mechanism and the weight M.415778 seat 213. Further, the center of mass of the abrasive sheet 4 and the composite rotating shaft base 2 is brought closer to the revolution axis, and even overlaps with the revolution axis, thereby reducing or eliminating vibration. Therefore, with the above-mentioned usage, this creation can be applied to a variety of abrasive sheets of different quality specifications, and can be adjusted to avoid excessive vibration during use. It has good use effect and wide product compatibility. With the effect of progress. [Simple description of the map]
