Abstract
A manual breechblock opening device that actuates a breechblock lever to open a wedge breechblock of a gun against an elastic return force includes a manual control member, a drivetrain and a holder. The manual control member is disposed within reach of an operator. The drivetrain includes a rotating output shaft coupled to the breechblock lever and a rotating input shaft coupled to the output shaft and coupleable to the manual control member. Actuating the manual control member rotates the drivetrain in a first rotational direction and causes the output shaft to engage the breechblock lever and to open the wedge breechblock. The blocking member is coupled to and disposed to prevent the rotation of the drivetrain in a second rotational direction that is opposite the first rotational direction.
