Please tell me what this is called

All Korean clocks that I have worked on have this component. The LH end runs on the centre cam and the RH end pushed the flirt up to release the rack and also to hold the warning pin until the LH end drops off the centre cam and initiates the strike. What is it called? Thank you

Strike "flirt", same as other clocks but the function is a little different. Willie X
