Flat key is installed；Described driven disc 1 is connected with output gear first 4, output gear second 15 respectively by gear transmission structure.Described
Gear transmission structure includes travelling gear first 2, gear shaft 13, travelling gear second 3, described travelling gear first 2 respectively with driven disc 1
And gear shaft 13 connects, gear shaft 13 is connected with output gear first 4 by travelling gear second 3；Described gear shaft 13 the most directly with
Output gear second 15 connects.Remainder is same as in Example 1.
Embodiment 3: a kind of drill bit formula capable of reversing wood drilling machine, including drill bit 8, power set 11, change speed gear box 10, described power
Device 11 is connected with drill bit 8 by change speed gear box 10, and described change speed gear box 10 is provided with reversing arrangement.Described reversing arrangement includes commutation
Knob 5 and diverter 6；Described change speed gear box 10 includes driven disc 1, output shaft 7, described output shaft 7 uses matched in clearance install
