FIELD: mechanical engineering.
SUBSTANCE: hammer catch (11) allows roller (17), installed rotary between two side plates (16), forming part of body (14) of hammer catch. At motion of twist-type trigger lever system, connecting twist-type trigger and hammer catch (11), forces hammer catch (11) turn back so that roller (17) interacts to surface (22) of cut, implemented in cock (21). This rolling releases cock (21) for impact by striker for implementation of shot of ammunition. When twist-type trigger is loosen, roller (17) of hammer catch rolls down into anchor and locking position into cuts 22, implemented in cock 21.
EFFECT: improved reliability of weapon.
