Description
Technical field
The disclosure relates generally to a kind of trigger assemblies, can be that various power tools carry more particularly, to one kind
For long-range locking feature and the trigger assembly for going locking feature.
Background technology
Most of electric products, such as power tool include with locking and the trigger switch for going latch functions.This lock
Only function and the other machinery component that latch functions usually couple by mechanical lock or with actuator is removed to implement, to prevent from activating
Device is when operator discharges trigger button back to a position in on/off position.However, this traditional mechanical lock
The undesirable certain limitations of manufacturer are applied to manufacturing process.For example, such construction by the locking of actuator and goes to lock
Only feature is limited to adjacent with trigger switch, or even if actuator is configured to far from trigger switch, it is also desirable to rigid mechanical
The position that linkage turns on/off to prevent trigger from returning in position.In addition, in order to manufacture this mechanical lock or
Remote mechanical linkage needs the high-precision between trigger switch, actuator and all components for being attached thereto or engaging
Manufacture and matching size so that these mechanical locks or remote mechanical linkage must be customized by each electric product.In view of dynamic
The maintenance of power tool and functionality, this mechanical lock or remote mechanical linkage are also undesirable, because accumulation is being locked
Or the dust around switch may block the abundant traveling of trigger during actuation phase, discharged so as to cause locking mechanism
When be out of order and then from on/off position in a position discharge trigger when fail.
