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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an eccentric handle device.BACKGROUND OF THE INVENTION[0002]The structure which need locking and unlocking frequently between parts can be seen in various fields during daily life and working. Owing to the adoption of eccentric handle locking device, the structures which need locking and unlocking frequently have become simple, and the operation has become more quick and convenient. Moreover, such locking device can also be used in the field of firearms to lock firearm aimer or other attachments used in the firearms on a guiding rail of the firearms quickly in this manner. However, in practical application, the locking device cannot be pressed tightly if the guiding rail of some firearms is smaller, otherwise the locking device cannot be mounted or is easy to break after being mounted if the guiding rail is larger, so that there are some inconveniences.SUMMARY[0003]The technical problem that the present invention aims to s...
