摘要：
The present invention discloses a passive self-ligating bracket, comprising a bracket body, wherein the middle part of the bracket body is sunken downwards to form an archwire slot； a locking piece in slide fit with the bracket body is arranged above the archwire slot； at least one locking position is provided on one of the bracket body and the locking piece； a fixing mechanism for fixing the locking piece at the locking position is arranged on one of the bracket body and the locking piece； the fixing mechanism comprises an elastic element located on one of the bracket body and the locking piece； the elastic element is provided with a bulge capable of being received at the locking position； when the locking piece is in a locked state, the bulge on the elastic element is received at the locking position； and when the locking piece is in an unlocked state, the end part of the bulge on the elastic element is in close abutment with one of the bracket body and the locking piece, and forces the elastic element to shrink and store energy. The present invention has the advantage of facilitating archwire installation.
