rotating shaft, drive the counter drive gear translation in rotating shaft, because the height of the vertical range between counter drive gear place plane with adjustment gear place plane and clutch projection is identical, therefore, the adjustment gears meshing counter drive gear after translation and support are rotationally connected.When driving-disc is rotated further, the counter drive gear that rotarily drives of rotating shaft rotates, and counter drive gear drives adjustment gear to rotate, and bevel gear rotates the reversion of adjustment gear driven, and reversion bevel gear drives the bit on main shaft and main shaft.Because reversion bevel gear is connected by adjusting gear with between counter drive gear, therefore, when main shaft keeps rotating clockwise, turning to from different before of main shaft, realizes the reversion of drill bit, in drill bit Umklapp process, scrap exits, and is convenient to continue boring, prevents becomes clogged with dirt drill bit.After clutch discs rotates past clutch projection, back-moving spring promotes driving-disc, rotating shaft, counter drive gear, clutch discs reset, and now, counter drive gear departs from adjustment gear, and the driving gear on driving-disc engages again with driving bevel gear, realizes holing.Driving-disc drives in the whole rotary course of rotating shaft, by coordinating of clutch and reversing device, realize turning to of driving-disc and remain constant, without the need to manual reversion, just can realizing the reversion withdrawing of the pulse frequency of drill bit, move back bits, due to without the need to repeatedly changing hand direction and action, therefore easily forming muscle memory, the rotating speed of manual rotation driving-disc can remain unchanged substantially, improves drilling quality and speed.
