Disclosed is a passive self-ligating bracket, comprising a bracket body (1), the middle of the bracket body (1) is downwardly concave to form an arch wire slot (11), a locking plate (2) in sliding fit with the bracket body (1) is arranged above the arch wire slot (11), one of the bracket body (1) and the locking plate (2) is provided with at least one locking position, one of the bracket body (1) and the locking plate (2) is provided with a fixing mechanism for fixing the locking plate (2) at the locking position, the fixing mechanism comprises an elastic part (4) positioned on one of the bracket body (1) and the locking plate (2), the elastic part (4) is provided with a protrusion (41) capable of being received by the locking position, when the locking plate (2) is in a locking state, the protrusion (41) of the elastic part (4) is received by the locking position, and when the locking plate (2) is in an opened state, the end part of the protrusion (41) of the elastic part (4) is tightly abutted against one of the bracket body (1) and the locking plate (2), and forces the elastic part (4) to retract and store energy. The self-ligating bracket adopting the above-mentioned structure has the advantage that an arch wire is convenient to mount. |
