The telescopic rod inner surface and drill bit week side clearance fit.
Further, the telescopic rod includes the second round tube and third round tube；If the second round tube inner surface offers
Dry sliding slot；Several sliding slot inner surfaces are fixedly connected to a spring；The third round tube week side is fixedly connected with several
Sliding block；The sliding block week, side was slidably connected with sliding slot inner surface.
Further, one surface of drill bit is fixedly connected with a diamond chip.
Further, the telescopic rod is glass transparent cover；Telescopic rod week side is equipped with scale.
Further, the first round tube inner surface is provided with thread groove.
The utility model has the following beneficial effects:
1, the utility model solves existing drill bit and gives up when in use by the Telescopic rod device outside drill bit
Material can scatter a ground, be not easily cleaned problem, have the advantages that labor-saving.
2, the utility model is by being arranged several drill bit, and it is many kinds of to solve existing drill bit, what is used
When, the problem of drill bit can waste many times is selected, is had the advantages that labor-saving.
Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.
