It holds, the surrounding outer wall of the bearing is welded with protective cover, and the surrounding outer wall of protective cover offers bolt hole, the connecting rod
Top outer wall and bottom end outer wall offer same first pin hole, and one side outer wall of connecting rod offers the second bolt
The side outer wall in hole, the drill bit is welded with connecting column.
Preferably, the structure of the connector and connecting column is hexagonal structure, and the inner wall and connecting column of connector
Outer wall matches.
Preferably, the top outer wall of the connecting column offers the third pin hole to match with the first pin hole, and even
One side outer wall for connecing column offers the 4th pin hole to match with the second pin hole.
Preferably, the structure of the groove be semicircular structure, and number of recesses be 16 to 20,16 to 20
A groove is symmetrically distributed on the upper and lower ends outer wall of mounting blocks.
Preferably, the structure of the protective cover is cylindrical structure, and the structure of mounting blocks is rectangular configuration, protective cover

Preferably, the connecting rod and drill bit are cylinder, and the outer diameter of connecting rod and the outer diameter of drill bit match.
The utility model has the following beneficial effects:
1, by increasing protective cover, so as to avoid the clast generated in process from flying into the company of drilling machine and drill bit
Socket part position causes to be stuck when more bit change.
2, by increasing the first pin hole, the second pin hole.Third pin hole and the 4th pin hole, so as to directly more
Bit change can not only save replacement and installation that resource can also be easier.
3, by increasing multiple grooves, drill bit is mounted on drilling machine so as to more firm, avoids drill bit shake de-
Caused by injure.
In conclusion not only installation and replacement are convenient but also safer for the drill bit.
