本发明涉及的自锁托槽，所述主体部第二端部的表面连接有T字形凸出部，所述盖体部朝向所述第一端部的侧面具有T字形凹槽部，所述凹槽部匹配于所述凸出部，凸出部与所述凹槽部的设计，使得盖体部与所述主体部之间的配合更加地紧密，盖体部不易于移动或者掉落，在使用过程中，避免出现盖体部的 移动，影响使用者的感受。
本发明涉及的自锁托槽，结扎槽的设计放便结扎丝结扎在所述结扎槽内，更有助于整个自锁托槽与弓丝之间的配合。保护翼的设计主要是为了防止结扎在结扎槽内的结扎丝脱位、移位。

必要时，通过结扎丝将弓丝固定于自锁托槽的结扎槽500，更加地牢固。
本发明涉及的自锁托槽，通过主体部、盖体部及连接部的配合，尤其是，通过主体部沿主槽沟方向上的尺寸大于在主体部横向平面内(横向方向)垂直于主槽沟方向上的尺寸，使得自锁托槽形成沿主槽沟方向上的类椭球形，或者，通过主体部沿主槽沟方向上的尺寸小于在主体部平面内(横向方向)垂直于主槽沟方向上的尺寸，使得自锁托槽形成沿主槽沟的短轴方向上的类椭球形。所述盖体部的表面且与主体部第一端部的表面匹配呈类椭球状，使得主槽沟的长度增大或减少，加大或减少了横径，增加了托槽对弓丝的控制长度，从而增加 了对牙轴的控制。另外，类椭圆球状的设计有效的降低了自锁托槽的表面高度，舒适度增加，使得患者在使用时，减少口腔中的不适感。
