Abstract:
1. A quick shaft and micro-adjusting device for the angle blocking plate of a planing machine comprising: a material conveying table, said material conveying table having one side connected with a fundamental base, said fundamental base provided thereon with an upper holding frame able to be guided to shift forward and backward, said upper holding frame having one side connected with an angle blocking plate, said angle blocking plate able to shift forward and backward together with said upper holding frame on said material conveying table, said angle blocking plate provided for positioning a wood material during planing work; said fundamental base having an underside wall of a top fixed with a support member extending downward, a shaft inserted through both one side plate of said fundamental base and said support member, said shaft having an outer end extending out of said side plate of said fundamental base and connected with a hand wheel, said shaft having an intermediate portion firmly fitted with a transmission gear, said transmission gear received in a hollowed groove bored in the upper side of said top plate of said fundamental base, said transmission gear having an upper portion protruding out of the upper side of said fundamental base, said shaft having an inner end inserted through said support member, two helical spring lock washers fixed on said shaft and respectively positioned at the opposite sides of said support member, said helical spring lock washers provided for stopping and restricting said shaft in position when said shaft shifts axially; and said upper holding frame having an underside provided with a lengthwise rack, said rack able to be moved and disengaged from said transmission gear on said shaft of said fundamental base to enable said upper holding frame and said angle blocking plate to be quickly moved forward and backward, said rack also able to be moved and engaged with said transmission gear to enable said angle blocking plate to be micro-adjusted in position by turning said hand wheel.
