[0046] Specifically, the handle 16 can be used to facilitate holding the rotating plate 6 to drive its rotation, the protective pad 17 thereon can improve the comfort of holding, the plug-in block 13 can improve the firmness of the push rod 12 when plugged in and fixed, and the rubber pad 14 thereon can increase the friction to further improve the fixing effect and provide buffering, and the device can be easily installed and fixed by installing screw parts in the positioning block 20 and the positioning hole 21 thereon.

[0047] Working principle: Before using the device, the operator first rotates the rotating plate 6 clockwise or counterclockwise and moves the moving block 7 at the same time to accurately engage with the card slot 23 on the rotating ring 5. In this case, when the rotating ring 5 is rotated, the positioning cover 1 can be driven to rotate at the same time, thereby driving the rotating column 24 and the threaded column 8 thereon to rotate together. At this time, since the threaded column 8 and the threaded cover 9 are connected by threads, the threaded cover 9 will move accordingly. This movement will drive the telescopic plate 11 to rotate and telescope, thereby pushing the push rod 12 out of the mounting cover 10. In this way, the push rod 12 can engage and plug the device to ensure its stability during operation.

[0048] By rotating the rotating plate 6 again and moving the moving block 7, it can be tightly engaged with the slot 23 on the mounting cover 10. At this time, the mounting cover 10 and the positioning cover 1 can be firmly fixed. At the same time, rotating the rotating ring 5 can drive the rotating column 24 and the gear 201 thereon to rotate. Through the transmission action of the belt 203, the rotating wheel 202 and the threaded rod 204 thereon can be driven to rotate. Since the threaded rod 204 and the threaded sleeve 205 are connected by threads, the threaded sleeve 205 will push the positioning cover 1 to move under the action of rotation, so that the milling cutter 4 on the positioning cover 1 can be telescopically adjusted to meet different processing requirements.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
