Background technology
In machinery industry, we always be unable to do without back-up ring when using securing member, are all need to use back-up ring that securing member is further reinforced under a lot of occasions. Such as axle hole back-up ring, we are typically on the spare and accessory parts of some machineries can see such back-up ring. For axle hole back-up ring, they are separately mounted on axle journal or are arranged in hole, and they make use of the principle that trace increases to realize fastening, say, that if be mounted on an axle, then the inner ring diameter of back-up ring is point more a little bit smaller than axle just; If back-up ring is arranged in hole, then the race diameter of back-up ring just than hole big little by little. So the manual words installed are highly difficult, so we are necessary for finding the apparatus of a kind of specialty, such as Circlip tongs, so back-up ring could be mounted on an axle or in hole. But in machinery industry, it is divided into interior Circlip tongs and purpose outside spring caliper due to Circlip tongs, moreover to change back and forth at any time in parts process is installed, and relatively bother, lose time, more be difficult to install with existing Circlip tongs as the back-up ring that moral mark series is special to some.
