By pulling the trigger and operating it linearly, the trigger switch is pushed in and turned on, the spark plug ignites, and the mixed gas in the combustion chamber burns. After the driving operation, the combustion chamber is opened.

  • a lockout bar formed integrally with the link member is arranged beside the cam plate interlocked with the trigger. For this reason, even if the trigger is pulled before the pressing operation of the contact arm, the cam plate cannot hit the lockout bar and cannot rotate, so the trigger cannot be pulled. In other words, the contact arm must be pressed against the material to be driven to form a sealed combustion chamber so that it can only be activated by pulling the trigger (see JP 2005-22069 A).

  • the trigger has an asymmetric shape as described above. There is also a slight clearance between the inner surface of the guide and the outer surface of the trigger. Therefore, when a finger is pulled on the trigger and pulled, a force is directly applied to the trigger body on which the finger is hooked, but a load for rotating the cam plate is applied to the divided trigger lever as described later. For this reason, a moment that turns the entire trigger works, and friction is generated between the inner surface of the guide portion and the outer surface of the trigger during pulling operation. Since the guide and trigger are made of synthetic resin and are relatively vulnerable to wear, wear gradually increases as the switch is repeatedly turned on and off.
  • the concrete debris when drilled scatters and adheres to the tool, further promoting wear between the guide portion and the trigger. If the guide wears excessively, the guide performance deteriorates, so the trigger rotates and tilts, and the trigger cannot be pulled to the stroke end, resulting in switching failure.
