[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, an oral cavity expander is disclosed, comprising a tube body 1 and two support plates 3. A strip-shaped opening 101 is provided on one side of the tube body 1. A first curved rod 4 is fixed on the outer wall of the tube body 1 above the strip-shaped opening 101. A second curved rod 5 is slidably connected inside the strip-shaped opening 101. A slot 31 is provided on one side of each of the two support plates 3, and the two support plates 3 are respectively sleeved on the surfaces of the first curved rod 4 and the second curved rod 5 through the slot 31. An adjustment component 7 for driving the movement of the second curved rod 5 is provided inside the tube body 1. A handle 2 for driving the adjustment component 7 is provided at the bottom of the tube body 1. A positioning component 8 is provided on the side of the upper surface of the handle 2. A plurality of locking holes 102 matching the positioning component 8 are provided on the lower surface of the tube body 1.

[0024] Magnets 6 are fixed to one end of the first bent rod 4 and the second bent rod 5 that are inserted into the slot 31, and iron plates are fixed to the inner side wall of the slot 31.

[0025] Therefore, when installing the support plate 3 on the surface of the first bent rod 4 and the second bent rod 5, the first bent rod 4 and the second bent rod 5 are directly inserted into the slot 31 of the support plate 3, and the support plate 3 is fixed by attracting the iron sheet with the magnet 6. When disassembling, the support plate 3 can be pulled off the surface of the first bent rod 4 and the second bent rod 5.

[0026] The adjustment assembly 7 includes a lead screw 71 that is rotatably connected to the inner wall of the tube body 1 via a bearing. An internal thread block 72 is rotatably connected to the surface of the lead screw 71. The second bent rod 5 passes through the strip opening 101 and is fixedly connected to the internal thread block 72. The bottom end of the lead screw 71 passes through the bottom wall of the tube body 1 and is fixedly connected to the handle 2.

[0027] When the handle 2 is rotated forward or reversely, the inner threaded block 72 can be driven to move up or down along the strip-shaped hole 101 by the screw rod 71, so as to drive the second bent rod 5 to move up or down, and the two supporting plates 3 are close to or away from each other.

[0028] The guide rod 73 is fixed in the pipe body 1 and penetrates through the inner threaded block 72 and is in sliding connection with the inner threaded block 72.

[0029] The guide rod 73 is arranged to guide the inner threaded block 72, so that the stability of the movement of the inner threaded block 72 is ensured.

[0030] The bottom end of the handle 2 is designed as hollow, so that the weight of the entire dilator is reduced.
