Single-hand operated trigger device

A single-hand operated trigger device, characterized in that the single-hand operated trigger device comprises:

• a switch assembly, including a first contact element, a second contact element, a first lead wire electrically connected to the first contact element, and a second lead wire electrically connected to the second contact element, wherein the first contact element moves along a first direction to contact the second contact element to form a conduction state or separates to form an open circuit state;
• a base assembly, including a support structure and multiple first extension members, wherein the support structure supports the second contact element, and the multiple first extension members are disposed on opposite sides of the support structure in a second direction and extend toward the second contact element along the first direction, wherein the second direction is orthogonal to the first direction;
• a pressing assembly, including a pressing body, an abutment element, and multiple second extension members, wherein the abutment element extends from the pressing body toward the first contact element along the first direction, and the abutment element abuts against the first contact element;
• the multiple second extension members are disposed on opposite sides of the pressing body in the second direction and extend toward the first contact element along the first direction;
• a control mechanism, disposed on the multiple first extension members and multiple second extension members, wherein the control mechanism includes multiple abutment protrusions and multiple abutment slots, and the multiple abutment protrusions are respectively abutted against the inner walls of the multiple abutment slots in the first direction.
