In addition to solving the problem that in documents, drill bit cannot expose, the application also solves contrast literary composition
There is another problem in part.In documents, telescoping tube is in middle part and the front portion of whole dust-proof cover for electric drill
(setting the front end as dust cover, the front end of drill bit), it is clear that boring when, dust cover is internal empty
Front portion between, dust or short grained concentration are relatively big, and these little granules suspended in space are easy to
Drop on the inwall in space, so the accumulation that the telescoping tube in documents is just easy to quickly is more
Dust, granule.And general, telescoping tube all uses plastic material, and intensity, hardness are poor, have accumulated
The when that after dust, granule, telescoping tube constantly compressing in boring procedure, just it is easy to occur harder
Granule blocks telescoping tube, it is impossible to the problem continuing to shrink, or harder, more sharp-pointed granule, may
Telescoping tube is cut.And the telescoping tube of the application is not exclusively located in the rear portion of dust cover, dust, granule are all
It is easier in the cover body not deformed upon, and, telescoping tube has electric drill to install the stop of pipe,
Dust is also not easily accessed the space at telescoping tube place.So dust in space, telescoping tube place, granule are close
Spending relatively low, telescoping tube is just not easy to accumulate dust, granule, thus reduces telescoping tube quilt largely
The probability cut.Additionally, due to telescoping tube is in the inside of electric drill installation pipe, the small volume of telescoping tube,
Its internal space is the least.So in the case of the distribution density of dust in space, granule is less,
Space inner volume is the least, so the total amount of the inner accumulation granule of telescoping tube is the least.So it is flexible
Pipe is not easy to be cut by granule, thus improves the durability of dust-proof cover for electric drill.
