Therefore, the rotating shaft 16 can rotate freely between the two mounting blocks 15. Since the gear 14 is sleeved on the rotating shaft 16, the rotating shaft 16 can drive the gear 14 to rotate. Since the turnover plate 7 is fixed to the gear 14, the gear 14 can drive the turnover plate 7 to turn from left to right or from right to left. The gear rack 8 is engaged with the gear 14, so when in use, the gear rack 8 is pushed to move to the left, the gear 14 rotates clockwise, and the gear 14 can drive the turnover plate 7 to turn during the clockwise rotation. During the turning of the turnover plate 7, the dustproof box 5 can be opened from the top, so that the turnover plate 7 does not block the top of the dustproof box 5, and the condition of the drill bit 1.5 in the dustproof box 5 can be observed from the top of the dustproof box 5, so that the drilling condition of the drill bit 1.5 can be observed without taking down the dustproof box 5.
[0029] In the implementation, the gear rack 8 in the driving assembly can also be directly replaced by a rotating handle. The rotating handle is specifically installed so that the front end of the rotating shaft 16 is inserted out of the front mounting block 15. Therefore, the front end of the rotating shaft 16 is located in front of the front mounting block 15. The rotating handle is installed on the rotating shaft 16 in front of the front mounting block 15. In use, the rotating handle is rotated to drive the rotating shaft 16 to rotate, and the rotating shaft 16 drives the gear 14 and the turnover plate 7 to rotate, so as to achieve the purpose of turning the turnover plate 7.
[0030] As shown in Figure 1 The bottom of the gear rack 8 is fixed with a second sliding block 9, and the top of the connecting plate 10 is provided with a second sliding groove for the left and right sliding of the second sliding block 9.
