Eccentric handle device

Abstract

An eccentric handle device which can be adapted for guiding rails of different sizes includes a base body ( 3 ), a pressure block ( 4 ), a pull rod ( 5 ), a pin ( 6 ), an eccentric handle ( 8 ) and a nut ( 1 ). The base body ( 3 ) is matched with the pressure block ( 4 ). The rod ( 5 ) passes through the base body ( 3 ) and the pressure block ( 4 ) respectively. One end of the rod ( 5 ) is movably connected with the eccentric handle ( 8 ) via the pin ( 6 ), the other end crosses the base body ( 3 ), and the rod is matched with the nut ( 1 ) by thread. The distance between the pressure block ( 4 ) and the base body ( 3 ) can be adjusted by rotating the nut ( 1 ), thus the device can be applicable to guiding rails of different sizes. The device can be widely used in the field of firearm aimer.
