[0021] As Figures 1 to 6As shown in the figure, the utility model discloses a detachable orthodontic bracket. The technical solution adopted is as follows: it includes a base plate 1, on the top of the base plate 1, a base 2 is fixedly installed. One end of the base 2 is provided with a slide bar 7, and a slide cover 3 is slidably installed on the outside of the slide bar 7. The middle part of the slide cover 3 is installed in the middle part of the slide bar 7 through a bolt 5. In the middle of the base 2, an upper clamping block 13 and a lower clamping block 14 are installed. At both ends of the middle part of the base 2, retaining seats 4 are respectively fixedly installed. Inside the retaining seats 4, retaining pieces 18 are provided. In the utility model, clamping blocks 20 are arranged on both outer sides of the slide cover 3, and retaining pieces 18 are arranged inside the retaining seats. The retaining pieces 18 form a block on the clamping blocks 20, and cooperate with the bolt 5 to fix the slide cover 3 on the outside of the slide bar, so as to complete the clamping of the arch wire by the upper clamping block 13 and the lower clamping block 14. When disassembling, only need to disassemble the bolt 5, pull the slide cover 3, the retaining piece 18 deforms, and the clamping block 20 disengages from the retaining piece 18, then the orthodontic bracket can be disassembled and adjusted.
