s4: pulling the lock mounting seat (75), rotationally clamping and fixing the lock mounting seat (75) and the inner side of the clamping mounting seat (73), and repeating the steps S1-S3.
8. The method of using a lock impact test device according to claim 7, wherein in step S4, a limit slide block is fixedly connected to one side of the lock mounting seat (75), a limit slide groove is provided on the inner side of the clamping mounting seat (73), the limit slide block is slidably connected with the limit slide groove, and the limit slide block and the limit slide groove are of a flower sleeve structure.
