Detailed Description

As shown in fig. 1-3: the utility model discloses can realize handheld two kinds of functions of polishing, the concrete implementation is: the left and right rotating wheels can be rotated by meshing the left and right gears 11 with the motor gear 10, and the sand 15 can be polished by rotating the right rotating wheel 9; when the left rotating wheel 9 is rotated, the rotating wheel 9 is a grinding wheel, so that the workpiece can be polished by the rotating wheel 9, and only one rotating wheel 9 is required to be rotated independently.

When the limiting plate 13 on the right side is positioned on the left side of the limiting spring block 8, the gear 11 is meshed with the motor gear 10, and the first spring 14 is in a compressed state at the moment, so that the gear 11 can be meshed with the motor gear 10 stably. When the gear 11 is separated from the motor gear 10, the right limiting plate 13 is pulled to the right, and because the lower end of the limiting spring block 8 is an inclined plane, the right limiting plate 13 is pulled to the right end of the right limiting spring block 8, and in the pulling process, the limiting plate 13 jacks up the limiting spring block 8 upwards and then reaches the right end of the spring block 8, at the moment, under the action of the second spring 19, the limiting spring block 8 is reset, at the moment, the limiting spring block 8 clamps the limiting plate 13, and the gear 11 and the motor gear 10 are separated successfully. When the right gear 11 is meshed with the motor gear 10 again, only the round rod 18 is required to be pulled out, the upper limit spring block 8 and the lower limit spring block 8 are separated, and the gear 11 is meshed with the motor gear 10 under the action of the first spring 14.

The rotating shaft 12 is in sliding fit with the cylinder 20, the slideway 21 plays a guiding role, and the cylinder 20 can move on the rotating shaft 12. The working process is to firstly set whether the gear 11 is meshed with the motor gear 10 or not and then start the switch 3 for starting.
