a groove 705 arranged on the front side wall of the bracket body 2;

a roll-over stand 706 movably mounted in the groove 705;

one end of the strut 707 is fixedly arranged on the sliding block IV 704, and the other end of the strut penetrates through the bracket column and extends into the groove 705 to be hinged with one side of the overturning frame 706;

and the second spring 708 is sleeved on the outer wall of the first support 707, and two ends of the second spring are respectively abutted against the fourth slider 704 and the inner wall of the sliding cavity 15 opposite to the fourth slider.

In this embodiment, because the above structure is adopted, when the cover plate 4 needs to slide in the direction away from the archwire slot 3, one end of the roll-over stand 706 is pulled to support the other end on the side wall of the groove 705, and the roll-over stand 706 is rotated around the hinge point with the first pillar 707, and the roll-over stand 706 is continuously pulled to drive the first pillar 707 and the fourth slider 704 slidably installed in the dovetail groove 703 to move in the direction of the roll-over stand 706, and through the cooperation of the fourth slider 704, the dovetail groove 703, the through groove and the upright column 702, the second slider 17 is driven in the sliding cavity 15 to slide in the sliding cavity 15 along the extending direction of the third through groove 701, the first spring 22 and the second spring 708 are compressed and shortened until the first slider 19 is separated from the first slot 20, at this time, the cover plate 4 is slid, the nickel-titanium tube 601 enters the transition groove from the second hole 502 and is compressed, the nickel-titanium tube 601 is elastically deformed through the deformation groove 602, and enters the first hole 501 along with the relative displacement of the cover plate 4, at the moment, the archwire slot 3 is opened for the removal and installation of the archwire, the roll-over bracket 706 is turned over again to be parallel to the groove 705, the first spring 22 and the second spring 708 lose the compression to push the fourth slider 704 and the second slider 17 to move away from the roll-over bracket 706, and the second slider 17 slides and resets along the extending direction of the third through slot 701.

Example 9:

in this embodiment, in addition to including the structural features of the foregoing embodiment, the sealing mechanism 8 includes:

two first sealing grooves 801 are formed in the top and the bottom of the second through groove 16 respectively;

two sealing grooves two 802 are respectively arranged at the top and the bottom of the third slider 18 and respectively correspond to the sealing grooves one 801;

sealing strips 803 disposed in respective sealing grooves one 801 and two sealing grooves 802;

a plurality of blind holes 804 are formed and are respectively arranged at the top of the first sealing groove 801 and on the side wall of the first sealing groove 801 facing the first slider 10;

a second support column 805 which is at least partially slidably mounted in the blind hole 804;

a third spring 806 arranged at the bottom of the blind hole 804;

and a support plate 807, one side wall of which is mounted at the end of the second support column 805 extending out and fixedly connected, and the opposite side wall of which is abutted against the outer wall of the sealing strip 803.

In this embodiment, due to the adoption of the above structure, by the arrangement of the plurality of sets of the springs three 806, the pillars two 805, and the support plates 807, pressure is applied to the top and one side wall of the sealing strip 803, so that the other side wall and the bottom of the sealing strip 803 are kept in close contact with the inner wall of the other side of the first sealing groove 801 and the bottom surface of the sealing groove, when the slider two 17 slides in the through groove three 701, the bottom surface of the sealing strip 803 is kept in close contact with the second sealing groove 802, sealing can be still kept, and dust and impurities are prevented from entering the sliding cavity 15 from between the slider two 17 and the through groove three 701.

Example 10:

in this embodiment, in addition to the structural features of the previous embodiment, the sealing mechanism 8 further includes:

two sliding grooves 808 are arranged, are oppositely arranged on the side walls at the front end and the rear end of the sliding cavity 15 and are close to the second through groove 16;

the sealing plate 809 is slidably mounted in the second sliding groove 808, and one end of the sealing plate is abutted to the outer wall of the third sliding block 18;

and the spring IV 810 is installed in the second sliding groove 808, and two ends of the spring IV are respectively abutted against one end, far away from the third sliding block 18, of the sealing plate 809 and the groove bottom of the second sliding groove 808.

In this embodiment, due to the adoption of the above structure, when the second slider 17 slides obliquely along the extending direction of the fourth through groove along with the first slider 10 in the third through groove 701, the front and rear ends of the second slider 17 and the third through groove 701 are kept sealed by the cooperation of the fourth spring 810, the sealing plate 809 and the second sliding groove 808, so that dust and impurities are prevented from entering the sliding cavity 15 from the front and rear ends of the second slider 17 and the third through groove 701.
