A safety catch mechanism for nail guns comprises a through hole at the upper
end
of a magazine of the nail gun, an axle section protruded from one side of the magazine
and pivotally coupled with a rotary rod, a blocking arm extended from the rear
end of the rotary rod, a blocking plate bent from the rear end of the blocking
arm for being extended and blocking the rear of the trigger; wherein a push arm
is extended from the front end of the rotary rod; a limit bracket is movably embedded
at the end of the push arm; a latch is defined on the limit plate to be protruded
from an inner wall of the magazine; by means of the foregoing structure, if the
magazine is loaded with nails, the latch can be pushed outward to drive the rotary
rod to rotate, so that the blocking plate is separated from the rear of the trigger
and allows users to cock the trigger.
