## 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.
