A kind of Novel electric hammer Architectural Equipment of collapsible shoulder support frame
Technical field
The utility model belongs to Architectural Equipment field, is specifically related to a kind of Novel electric hammer Architectural Equipment of collapsible shoulder support frame.
Background technology
Electric hammer is on the basis of electric drill, add one and driven the piston having crankshaft-link rod by motor, reciprocating air in a cylinder, cylinder inner air pressure is made to be mechanical periodicity, the air pressure of change drives the hammer in cylinder back and forth to hit the top of drill bit, seems that we use hammer percussive drill bit. a therefore named electric hammer! Because the drill bit of electric hammer also creates the faster reciprocal motion in the direction along electric drill bar while rotating, so it can punch fast on the materials such as the large cement concrete of fragility and stone material.Generally use in building trade now, because its advantage is that efficiency is high, aperture is large, and drilling depth is long, instead of traditional method, save a large amount of manpower and materials, improve operating efficiency, but electric hammer relies on hand strength to support it, so worker's fatiguability, and easily injured, bring very large inconvenience to user.
