The diameter of the through-hole 56 (here the cross-sectional dimension for a non-circular through-hole 56) is large enough that the movable block 50 can move back and forth at least in the gingival direction. In this embodiment, the material of the movable block 50 is preferably identical to the material of which the body is made, which is the conventional material of the orthosis.

The second end 54 of the movable block 50 is smoothly engaged with the outer surface of the first wing 13 to form a portion of a curved surface. At the junction, the movable block 50 and the first wing 13 are each partially recessed, together forming a traction hole provided with an internal thread, the traction hole matching the abutment traction peg 40, and the second end 54 of the movable block 50 forms part of the bottom of the traction hole, thereby at least limiting the movement of the movable block 50 in the gingival retraction direction. The tow pin 40 may be a threaded rod or screw.

The portion of the end face of the first end 52 near the bottom of the main groove 11 is a slope, and the slope approaches the first wing 13 in the direction in which the main groove 11 opens to the bottom of the main groove 11. The bevel mates with a beveled shaped archwire 60.

The upper surface 58 of the movable block 50 is exposed outside the opening through groove 132 of the first wing 13, the movable block 50 is provided with a guide structure, the guide structure of this embodiment is a boss 581, the locking plate 20 is provided with a pair of guide rails outside the groove 21, and the guide rails are correspondingly connected with the outer edges of opposite sides of the boss 581 of the movable block 50, so that the locking plate 20 slides on the first wing 13 perpendicular to the main groove 11 under the guidance of the movable block 50. The structure of the guide rail and the connection relation between the guide rail and the boss 581 refer to the first groove 21 and the first protrusion (the description of the patent is shown in fig. 8 and 10 and the description is written in the text) disclosed in the utility model patent CN 201511024675.0. The specific structure and working principle thereof are not described in detail herein.

The steps of assembling the corrector of the present embodiment are that, firstly, the elastic member 30 is mounted on the body, specifically, the root of the elastic member 30 is inserted into the blind hole of the first wing portion 13, and the root of the elastic member 30 is fixed; then, the movable block 50 is mounted on the body, specifically, the movable block 50 is placed in the opening through slot 132 of the first wing part 13, and the through hole 56 of the movable block 50 is sleeved with the elastic piece 30; finally, the locking piece 20 is mounted on the body, specifically, the guide rail of the locking piece 20 corresponds to the boss 581 of the movable block 50, and the locking piece 20 slides from the first wing portion 13 to the second wing portion 15, so that the functional end of the elastic piece 30 enters the groove 21 of the locking piece 20, and the assembly is completed.

The use method of the embodiment is that the sliding lock piece 20 opens the main groove 11, under the avoidance of the movable block 50, the arch wire 60 has enough space to enter the main groove 11, then the sliding lock piece 20 is reversely slid to close the main groove 11, the traction bolt 40 is matched with the butt joint traction hole, the second end 54 of the movable block 50 is propped against, the first end 52 of the movable block 50 is propped against the arch wire 60 in the main groove 11, thereby reducing the clearance of the arch wire, and achieving the purpose of accurate correction.

It should be noted that the degree of embedding of the traction bolt can be adjusted, if the degree of embedding is large, the arch wire is abutted, and if the degree of embedding is small, the arch wire has a little movable space. In particular according to the correction requirements.

Compared with the prior art, the movable block of the embodiment is in wide sleeve joint with the elastic piece, enough arch wire avoiding space is provided for the movable block, after the arch wire enters the main groove, the traction bolt is arranged, and the traction bolt controls the movable space of the movable block, so that the movable space of the arch wire in the main groove is controlled, and the effects of reducing the arch wire clearance and accurately correcting are achieved. Compared with the stop bracket in the prior art, the locking effect of the movable block is more stable and durable.

In other embodiments, the end face of the first end may be planar, as is suitable for conventional archwires. On the basis, the part of the end face of the first end, which is close to the opening of the main groove, is a bevel table surface for guiding the arch wire.

It can be seen that the end face of the first end can be deformed into other inclined surfaces, curved surfaces or a combination thereof with a straight plane to accommodate different shaped archwires. The inclined plane or the curved surface approaches to the side wall of the other side of the main groove in the direction from the opening of the main groove to the bottom of the main groove; alternatively, the inclined or curved surface is remote from the other side wall of the main trench in a direction of the main trench opening toward the bottom of the main trench. The movable block is matched with the opposite arch wire, so that the clearance of the main groove is effectively controlled, the torque is accurately expressed, and the correction effect is better.

In this embodiment, the end face of the first end penetrates through and is part of a side wall of the main groove, so that the end face is designed to facilitate machining and assembly. In other embodiments, the end face of the first end penetrates through a side wall of the main slot and covers other parts of the side wall, and the locking force of the movable block is uniformly distributed on the archwire, so that the locking effect is improved.

In other embodiments, the appliance may be a spherical appliance, or a square appliance.

In this embodiment, the second end of the movable block is externally positioned and forms the traction aperture. In other embodiments, the outer surface of the first wing portion entirely forms the traction aperture, and the second end of the movable block is disposed within the traction aperture, and the second end of the movable block forms at least a portion of the bottom of the traction aperture. So that the embedding of the traction bolt can push the second end of the movable block.

In other embodiments, the space for accommodating the movable block is a bar-shaped through slot, that is, the slot body has only two openings, and the upper end face of the corresponding cover plate is not opened. The two ends of the strip-shaped through groove are respectively communicated with the main groove and the traction hole. The cover plate slides through matching butt joint with the first wing part, and a through hole for allowing the elastic piece to penetrate is reserved on the upper end surface of the first wing part.

Wherein the elastic member is made of super elastic material including stainless steel, titanium alloy or nickel-titanium alloy or other suitable materials. Further, the spring is pressed or slid into place in the blind hole during assembly and/or may be secured thereto by employing techniques including staking, spot welding, laser welding, adhesives or other suitable methods to prevent relative movement therebetween.

The present utility model is not limited to the above-described embodiments, but, if various modifications or variations of the present utility model are not departing from the spirit and scope of the present utility model, the present utility model is intended to include such modifications and variations as fall within the scope of the claims and the equivalents thereof.
