The first rod body 1 is sleeved on the second rod body 2 and can slide or rotate relative to the second rod body 2, so that the length between the sleeved first rod body 1 and the sleeved second rod body 2, which is limited by the first end 11 and the second end 21, is adjustable.
The first rod body 1 comprises a first sleeving end 12 far away from the first end 11, and the first sleeving end 12 is provided with an external thread; the second body of rod 2 establishes the end 22 including keeping away from the second of second end 21 the second cover, and the second cover is established and is equipped with the internal thread on the end 22, but the internal thread on the end 22 is established to the first external screw thread adaptation of establishing on the end 12 soon to connect the second cover.
The surface of the first rod body 1 or the second rod body 2 is provided with a rotating hole 3, and the rotating hole 3 can be matched with an inserting handle to rotate the first rod body 1 or the second rod body 2. In this embodiment, the outer surface of the second rod body 2 is provided with the rotating hole 3, the rotating hole 3 is provided with a plurality of holes, when the first rotating hole is rotated to a hidden position in the oral cavity, the handle can be inserted into the rotating holes of other positions, and the second rod body 2 can be conveniently and continuously rotated.
The first end 11 is provided with a soft pad 13, and the second end 21 is provided with a soft pad 23.
The second rod body 2 includes a rod body 24 and an abutting portion 25 capable of abutting against teeth, and an elastic member (not shown in the figure) is provided between the rod body 24 and the abutting portion 25.
In actual operation, first the first rod 1 or the second rod 2 is rotated to a shorter length, then the first rod is placed at the edentulous position 30, the handle is inserted into the rotation hole 3, the second rod 2 is rotated by the handle, the length between the first rod 1 and the second rod 2, which are sleeved and defined by the first end 11 and the second end 21, is gradually extended until the first end 11 and the second end 21 tightly abut against the teeth 10 and 20, and the operation is completed. As the teeth are gradually returned, the gap of the edentulous position 30 is also enlarged, so that the second rod 2 is rotated at intervals, the length of the orthodontic mechanism is extended, the constant and lasting acting force on the teeth is kept, and the orthodontic effect is better.
Example two:
referring to fig. 4, the orthodontic mechanism of the present invention comprises: a first adjustment unit 1 comprising a first end 11 abuttable against a tooth; a second adjustment unit 2 comprising a second end 21 abuttable against another tooth; the first rod body 1 and the second rod body 2 are hollow round tubes. The end surface areas of the first end 11 and the second end 21 are larger than the cross-sectional areas of the first adjusting unit 1 and the second adjusting unit 2.
The second adjusting unit 2 is sleeved on the first adjusting unit 1, the first adjusting unit 1 and the second adjusting unit 2 are screwed through threads, and the first adjusting unit 1 or the second adjusting unit 2 is rotated, so that the length between the sleeved first adjusting unit 1 and the sleeved second adjusting unit 2 defined by the first end 11 and the second end 21 is adjustable.
