Preferably, the keeper outer wall is provided with fin.

By above-mentioned technical proposal, fin is easy to workman to hold, take keeper or by keeper be connected to gear bits cup It was easy to hold when upper, moves.

Preferably, the size of the cavity passes through for blade.

By above-mentioned technical proposal so that one end that keeper can install blade from rotating shaft skids off, and is conveniently replaceable positioning Part.

Preferably, the size of the cavity is adapted with gear bits cup inwall,

By above-mentioned technical proposal so that cavity also functions as the function of gear bits, and does not stop that cutting swarf is entered from cavity Inside shelves bits cup.

Preferably, the cavity is connected with gear bits cup interior walls be smooth.

It is by above-mentioned technical proposal, in smoothing junction that gentle the entering from cavity of cutting swarf is kept off in bits cup, it is to avoid cutting Bits are stuck in cavity and are considered to be worth doing in the gap that cup intersects with shelves, so as to lead to not exclude.

Preferably, being provided with some chip-removal holes on the gear bits cup.

By above-mentioned technical proposal, clap bits hole and be easy to the cutting swarf saved bit by bit in shelves bits cup to exclude, there is provided be convenient.

Preferably, the keeper is made up of engineering plastics.

By above-mentioned technical proposal, engineering plastics have excellent combination property, and rigidity is big, and creep is little, high mechanical strength, Heat-resist, electrical insulating property is good, and lightweight, can mitigate the power of hand held drilling instrument expense when workman drills.

In sum, this utility model has the advantages that：Course of processing convenient power-saving, keeper ensure that and add The centrage that work is portalled is vertical with surface of the work, that is, ensure that surface of the work is bright and clean, complete while the linearity in processing hole, it is to avoid Which receives the destruction of boring bar tool.
