[0026] Please refer to Figure 3 -

[0027] Figure 4 On one side of the large gear 601, a small gear 606 for driving the large gear 601 to rotate is rotatably connected. The large gear 601 and the small gear 606 are meshed with each other. An arc-shaped groove 604 is formed inside the large gear 601. A push rod 605 for pushing the protection plate 602 to move is slidably connected to the bottom of the arc-shaped groove 604. Specifically, a sliding rod 607 is slidably connected inside the arc-shaped groove 604. The bottom of the sliding rod 607 is fixedly connected to the top of the push rod 605. The bottom of the small gear 606 is rotatably connected to the inner cavity of the bent plate 5 through a bearing. And a motor 608 for driving the small gear 606 to rotate is fixedly installed in the inner cavity of the bent plate 5. The output shaft of the motor 608 is fixedly connected to the top of the small gear 606. By driving the motor 608, its output shaft drives the small gear 606 to rotate, and the small gear 606 drives the large gear 601 to rotate, so that the large gear 601 pushes the sliding rod 607 through the arc-shaped groove 604 to drive the push rod 605 to move, and adjusts the positions of the protection plate 602 and the rubber protection strip 603 according to the size of the drill bit 4, so that the protection plate 602 and the rubber protection strip 603 are close to the outer wall of the drill bit 4.
