On excircle.
Had the beneficial effect that caused by the utility model：A kind of dustless environment protecting electric hammer for metope punching of the utility model
At work, in the presence of the frictional force between outer shaft and bearing top circle week, extension board is fitted tightly on wall, works as electricity
When hammer bit enters wall, extension board needs to overcome outer shaft with driving outer shaft after the frictional force on bearing top circle week in bearing
Excircle on slide, in this process because there is the presence of frictional force, outer shaft can provide a thrust all the time to be made to prolong
Plate is stretched to be fitted tightly on wall, moreover, thrust also can be to having shaken certain cushioning effect caused by electric hammer work, this
The dust removing effects of utility model are good, and installation replacing is all more convenient, are easy to and existing electric hammer combines, its overall performance safety
Reliably, efficiency of dust collection is high, compares and is adapted to use in the construction operation environment of complexity, can effectively improve the work of operating personnel
Make environment.
