Hand held impact device |
摘要 |
A hand held impact device comprising a housing and an impact mechanism located therein. The housing is provided with an opening at its front end through which opening a working tool is introducable to receive impacts from the impact mechanism. A maneuver handle for direct, manual guidance of the working tool is freely displaceable along the working tool shank and is formed with a rear annular recess for being attachable to a cylindrical neck portion on the housing. The neck portion is coaxial with the working tool opening and forms a coupling means for the maneuver handle. The neck portion is provided with a groove with which spring biased balls on the maneuver handle are arranged to cooperate in order to releasably retain the maneuver handle in its supported position on the housing. The maneuver handle comprises a steel socket and a rubber sleeve which extends ahead of the steel socket to form a resilient, vibration insulating grip element.
