Adjustable safety assembly of a nail driver

Abstract

An adjustable safety assembly of a nail driver comprises a safety rod; an adjusting wheel; a resisting rod; a screw rod passing through the safety rod, adjusting wheel, and resisting rod sequentially; the screw rod being at a front end and the resisting rod being at a rear end; and a retaining seat having an open section; the adjusting wheel being position in the open section; and the screw rod passing through the retaining seat; When the adjusting wheel is rotated, the adjusting wheel moves in the open section of the retaining seat along a thread of the screw rod so as to drive the safety rod to achieve the effect of adjusting the position of the safety rod. The adjusting wheel is installed at a position far away from the beating opening so that the mistake in adjustment is reduced.

What is claimed is: 
     
         1 . An adjustable safety assembly of a nail driver comprising:
 a safety rod;   an adjusting wheel;   a resisting rod;   a screw rod passing through the safety rod, adjusting wheel, and resisting rod sequentially; the screw rod being at a front end and the resisting rod being at a rear end;   a retaining seat having an open section; the adjusting wheel being positioned in the open section; and the screw rod passing through the retaining seat;   wherein when the adjusting wheel is rotated, the adjusting wheel moves in the open section of the retaining seat along a thread of the screw rod so as to drive the safety rod to achieve the effect of adjusting the position of the safety rod.   
     
     
         2 . The adjustable safety assembly of a nail driver as claimed in  claim 1 , wherein the screw rod has a through hole and is installed at the front end of the screw rod; an elastic unit is installed between the safety rod and the safety rod so that the safety rod is adhered to the adjusting wheel. 
     
     
         3 . The adjustable safety assembly of a nail driver as claimed in  claim 1 , wherein a front end of the safety rod has a resisting portion; the resisting portion is installed at a beating opening; when the resisting portion is pressed inwards, the safety rod will cause the resisting rod to reduce inwards to have a state of triggering. 
     
     
         4 . The adjustable safety assembly of a nail driver as claimed in claim  1 , wherein one end of the resisting rod is formed with a resisting portion for resisting an ejecting sheet of a trigger so as to control the triggering of the trigger. 
     
     
         5 . The adjustable safety assembly of a nail driver as claimed in  claim 1 , wherein one end of the retaining seat has an elastic unit for resisting against the resisting rod so that when no force is applied, the trigger can not be actuated.
