Interior extension, it is to avoid projection extension produces excessive active force to the blind pore wall of drill steel body, so that damaging drill steel
Body.
Running through the pin-and-hole of blind hole owing to drill head is provided with, projection is provided with the through hole corresponding with pin-and-hole position,
Being provided with steady pin in pin-and-hole, steady pin passes through hole, steady pin and the through hole hole wall near drill head side
Between leave gap, it is to avoid due to projection top extend cause projection displacement to prop up steady pin, even destroy
Steady pin, it is ensured that drill head easy accessibility.
Owing to mounting structure includes the axially extended blind hole that is arranged on drill head end face, the end of drill steel body
Face is provided with projection, projection and blind hole interference fit, and in use, drill head is not only by axial
Impulsive force, also suffers from the pincer attack power in circumference so that drill head preferably clamps projection, is difficult to turn around.
Being revolving body owing to leading power portion, the bus leading power portion includes two outwardly camber lines, and two camber lines are mutual
In smoothing junction so that the power portion of leading has enough caliber sizes, there is enough intensity to conduct impulsive force,
Make again to lead between power portion and blind pore wall and butt tapered hole simultaneously and there is sufficiently large gap, in case projection prolongs
Exhibition.
Owing to the distance between pin-and-hole two ends is more than the length of steady pin, one end of pin-and-hole is provided with restriction steady pin
The limiting section passed, the other end of pin-and-hole is provided with plug, and plug has certain elasticity, is using vibrations
During, well can close pin-and-hole and not shift, it is to avoid impact in dust enters into pin-and-hole during use
The dismounting of steady pin.
Owing to drill head is the drill head that high-abrasive material is made, wear-resisting intensity is high, uses with existing drill steel entirety
High Strength Wear-Resistance Material is compared, and is greatly saved cost.
