Trigger assembly

Abstract

A trigger assembly includes a body having a pivot, and a hook is mounted to the pivot. The body has a chamber, and a path communicates with the chamber. A first positioning unit is located in the path, and a safety member is located in the chamber which has two slots and the. The first positioning unit contacts the slots. An activation member is located on the top of the safety member and has a guide groove and a positioning hole. A guide rod on the safety member is located in the guide groove. A second positioning unit is located in the body and contacts the positioning hole. A pivotal member is pivotably connected to the body and has an end contacting a push portion of the activation member. A spring is mounted to the protrusion and contacts the inside of the body. The trigger assembly includes two safety protections.
