The traction bracket that this utility model relates to, described first groove is along the cross section semicircular in shape on described major trough ditch direction, described second groove is along the rectangular in cross-section on described major trough ditch direction, and one of them edge of described second groove notch has the outstanding limit extended towards another edge direction; First connection side of described connecting portion is matched with the first groove, and described second connection side is in the L shape being matched with the second groove.Two ends are obvious with regard to the differences in shape of two grooves, when mounted, are easy to be in place once, avoid occurring the phenomenons such as the anti-dress of connecting portion.
The traction bracket that this utility model relates to, the surface of described main part the second end is connected with T-shaped protuberance, described cover body part has T-shaped concave part towards the side of described first end, described concave part is matched with described protuberance, the design of protuberance and described concave part, make between cover body part with described main part coordinate more tight, cover body part is not easy to move or drop, in use, avoid the movement occurring cover body part, affect the impression of user.
The traction bracket that this utility model relates to, the design of ligation groove puts the ligation of constipation tied silk in described ligation groove, more contributes to whole traction bracket and coordinating between arch wire.The design of the protection wing is mainly in order to prevent the ligature dislocation of ligation in ligation groove, displacement.
The traction bracket that this utility model relates to, the first end of described main part also comprises and only locks towing pad, described only lock towing pad one end open is in the surface of described main part first end, and the other end is opened on the side of described main part first end towards cover body part.Only better guaranteed of the design of the lock towing pad dismounting that makes to draw bracket, cover body part cannot normally with main part from time, firmly can be headed into by described towing pad insertion steel pipe of only locking, make cover body part stressed with main part from.
The traction element of the traction bracket that this utility model relates to is easy for installation, except can assisting the slip of bracket, completes the stop of bracket and arch wire, and reach corresponding rectification effect after can also changing towing pin (only locking bolt).
The orthodontic method that this utility model relates to, easy and simple to handle, described device fabrication is simple, and cost is low, and manual operation is easy, saves time and manpower, and in use, safer.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
