DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figures 1 to 5 ,in Figure 1 A schematic structural diagram of a preferred embodiment of an oral cavity opening device for oral care provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the right side view structure of the first rotating rod and the second rotating rod is shown; Figure 3 for Figure 1 An enlarged schematic diagram of the structure of region A is shown; Figure 4 for Figure 1 A top view structural schematic diagram of the upper support block shown; Figure 5 for Figure 4 The top view cross-sectional structure diagram of the sleeve shown, an oral cavity opening device for oral care, comprising: an upper support block 1;

[0024] The upper support block 1 is rotatably connected to the first rotating rod 2 on the front side, and the first rotating block 3 is fixedly connected to the right side of the first rotating rod 2. The first rotating block 3 is rotatably connected to the upper support block 1. The bottom of the first rotating rod 2 is slidably connected to the second rotating rod 4, and the back of the second rotating rod 4 is fixedly connected to the second rotating block 6. The second rotating rod 4 is rotatably connected to the lower support block 5 through the second rotating block 6. A sliding groove 7 is provided inside the first rotating rod 2, and a limiting plate 8 is fixedly connected to the upper end of the second rotating rod 4. A side block 9 is fixedly connected to the right side of the first rotating rod 2, and the side block 9 is slidably connected inside A limiting block 10 is provided, and a clamping block 11 is fixedly connected to the left side of the limiting block 10. A clamping slot 12 is provided on the right side of the second rotating rod 4, and there are multiple groups of clamping slots 12. The clamping slots 12 match the clamping blocks 11. A pull rod 13 is fixedly connected to the right side of the limiting block 10. A first spring 14 is sleeved on the side surface of the pull rod 13. A pull block 15 is fixedly connected to the right side of the pull rod 13. The first rotating rod 2 and the second rotating rod 4 can be limited by cooperating with the clamping slot 12 and the clamping block 11, so that the upper support block 1 and the lower support block 5 can be supported.

[0025] A connecting block 16 is fixedly connected to the left side of the upper supporting block 1 , and a connecting groove 17 is provided on the left side of the connecting block 16 . The connection block 16 is conveniently connected to the first connecting plate 19 through the arrangement of the connecting block 16 .

[0026] A limiting rod 18 is fixedly connected inside the connection groove 17 , and a first connecting plate 19 is rotatably connected to a side surface of the limiting rod 18 .

[0027] A sleeve 20 is fixedly connected to the left side of the first connecting plate 19 , and a connecting rod 21 is sleeved inside the sleeve 20 .

[0028] A second connecting plate 22 is fixedly connected to the right side of the connecting rod 21 , and two groups of second connecting plates 22 are provided. The second connecting plates 22 are rotatably connected to the lower support block 5 , and the connection structure between the second connecting plates 22 and the lower support block 5 is the same as that of the connecting block 16 .

[0029] A torsion spring 23 is sleeved on the side surface of the connecting rod 21, one end of the torsion spring 23 is fixedly connected to the connecting rod 21, and the other end of the torsion spring 23 is fixedly connected to the sleeve 20. The setting of the torsion spring 23 can generate torsion between the connecting rod 21 and the sleeve 20, so that the upper support block 1 and the lower support block 5 are stretched apart through the second connecting plate 22 and the first connecting plate 19.

[0030] The working principle of the oral cavity opening device for oral care provided by the utility model is as follows:

[0031] The first step: when in use, use dental forceps to pull the pull block 15 to the right, and the pull block 15 pulls the limit block 10 to the right through the pull rod 13. At this time, the limit block 10 drives the clamping block 11 to move to the right. When the clamping block 11 moves out of the clamping slot 12, the second rotating rod 4 can slide inside the sliding slot 7. At this time, the upper support block 1 and the lower support block 5 can be closed.

[0032] Step 2: The elastic force of the torsion spring 23 can generate torsion between the sleeve 20 and the connecting rod 21. At this time, the connecting rod 21 and the sleeve 20 can open the upper support block 1 and the lower support block 5 through the second connecting plate 22 and the first connecting plate 19. Through this mechanism, the upper support block 1 and the lower support block 5 can be automatically opened when not squeezed by external force.

[0033] Compared with the related art, the oral cavity opening device for oral care provided by the utility model has the following beneficial effects:

[0034] Use dental forceps to pull the pull block 15 to the right, and the pull block 15 pulls the limit block 10 to the right through the pull rod 13. At this time, the limit block 10 drives the clamping block 11 to move to the right. When the clamping block 11 moves out of the clamping slot 12, the second rotating rod 4 can slide inside the sliding slot 7. At this time, the upper support block 1 and the lower support block 5 can be closed. This mechanism is not easy to cause discomfort to the patient and is very convenient to use. The elastic force of the torsion spring 23 can generate a torsion between the sleeve 20 and the connecting rod 21. At this time, the connecting rod 21 and the sleeve 20 can open the upper support block 1 and the lower support block 5 through the second connecting plate 22 and the first connecting plate 19. This mechanism can automatically open the upper support block 1 and the lower support block 5 when they are not squeezed by external force. It is more labor-saving and very convenient to use.
