Abstract:
A nailing machine comprising:a housing containing a nail hitting mechanism for hitting nails;a contact arm for pressing against a work;a trigger lever having an end pivotally connected to the housing;a contact lever having a lower end pivotally connected to the trigger lever and an upper end actuatable by the contact arm when the contact arm is pressed against the work; anda pressing member comprising a first end pivotally connected to the trigger lever and a second end, the pressing member further comprising an arcuate portion on a side thereof,whereby when the contact arm is firstly pressed against the work and the trigger lever is pulled subsequently to activate the nail hitting mechanism via transmission by the contact lever, the arcuate portion of the pressing member bears against the housing such that the contact lever is immobile when the contact arm is disengaged from the work and when the trigger lever is kept pulled after hitting the nail to the work, the nailing machine being thus in a one-shot mode; andwhereby when the trigger lever is firstly pulled such that the second end of the trigger lever bears against the housing, and the contact arm is subsequently pressed against the work and thus actuates the contact lever to activate the nail hitting mechanism for hitting a nail, the contact lever is returned to its original position when the contact arm is disengaged from the work and when the trigger lever is kept pulled after hitting the nail, the nailing machine being thus in a successive nailing mode.
