Claims

[Scope of utility model registration request]

The cylinder body of the vibration isolation mechanism is formed by interposing a spring member in two chambers formed by a cylinder body and a piston movably fitted into the cylinder body, and the cylinder body is attached to the rock drill body or the grip of the handle. and the piston is connected to the other, the air supply passage is provided in an air supply passage that supplies air for operating the rock drill from an air supply source to the rock drill main body, and the piston is connected to the other. A throttle mechanism operates and stops the rock drilling machine by opening and closing a passage, and the throttle mechanism operates in conjunction with the opening and closing operation of the air supply passage, and when the air supply passage is closed, air from the air supply source is It is characterized by having a switching mechanism that allows the air to flow into one of the two chambers formed in the vibration isolating mechanism, and opens the chamber into which air flows in the closed state to the atmosphere in the open state. Anti-vibration handle for rock drill.
