[0009] Preferably, a movable groove is formed through the outer wall of the rotating rod, and the movable groove extends into the sliding groove, and the fourth mounting block is arranged inside the movable groove.

[0010] Preferably, the second mounting block is located below the third mounting block.

[0011] Preferably, the three scrapers are evenly distributed on the outside of the drill bit.

[0012] Compared with the prior art, the present application provides a hole-reaming device with adjustable angle for drilling, which has the following beneficial effects:

[0013] The hole reaming device with adjustable angle for drilling is provided with an electric push rod, a slider, a first connecting rod and a second connecting rod. When the hole reaming device is used, the electric push rod drives the movement of the slider, so that the first connecting rod and the second connecting rod push the scraper to adjust the angle, so that the hole reaming device can be adjusted in size and can be suitable for holes of different sizes.
