[0002] At present, in the traditional sandblasting process for the base plate of orthodontic brackets, sandblasting treatment is mainly carried out one by one by manual and simple tooling, with low efficiency. Moreover, there is no protection for the bracket matrix, and it is easy to spray onto the surface of the bracket during sandblasting, resulting in damage to the bracket surface and defective products. In addition, because the brackets are relatively small, when sandblasting, the brackets are clamped by bracket forceps for sandblasting treatment, which is very troublesome and easy to drop accidentally. It is difficult to find if it drops into the sandblaster. Content of the Utility Model

[0006] According to another embodiment of the utility model, it further includes that the upper surface layer of the bracket fixing plate is provided with uniformly arranged protruding blocks. Transverse grooves and longitudinal grooves are formed between the uniformly arranged protruding blocks, and holes are also provided between the protruding blocks.

[0007] According to another embodiment of the utility model, it further includes that long cylindrical pins or short cylindrical pins are arranged in the holes between the protruding blocks, and the long cylindrical pins and short cylindrical pins do not protrude from the bracket fixing plate.

[0008] According to another embodiment of the utility model, it further includes that the key strip layer includes three types of key strips, namely key strip I, key strip II, and key strip III, and the key strip I, key strip II, and key strip III are horizontally embedded in the grooves of the bracket fixing plate.

[0009] According to another embodiment of the utility model, it further includes that the holes provided on the polyurethane plate correspond to the holes on the bracket fixing plate.

[0010] According to another embodiment of the utility model, it further includes that the cover plate is provided with longitudinal grooves.

[0011] According to another embodiment of the present utility model, it further includes that the cover plate and the bracket fixing plate are fixedly connected by a cross recessed countersunk head screw one and a cross recessed countersunk head screw three.

[0012] The beneficial effects of the present utility model are as follows: When installing the bracket with this orthodontic bracket base plate sandblasting tooling, the bracket base plate is embedded in the rubber holes of the sandblasting tooling, so as to provide all-round protection for the bracket base body, avoid accidentally spraying the bracket base body during sandblasting and causing damage to the bracket surface, improve the sandblasting qualification rate, and reduce the generation of defective products. There is a round hole on the back of each fixing hole of the orthodontic bracket of the tooling, which is convenient for quickly ejecting the product and improves the production efficiency.
