[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Please refer to Figure 1-Figure 4 , a new type of mouth opener, comprising:

[0036] The support arm 1 is two in number and symmetrically arranged. A connecting frame 2 is arranged at one end of the two support arms 1 close to each other, and the two support arms 1 are rotatably connected to the connecting frame 2; an adjusting rod group 3 is arranged at the lower end of the connecting frame 2, and the adjusting rod group 3 is movably connected to the ends of the two support arms 1 for driving the ends of the support arms 1 to move; specifically, a rotating shaft 7 is fixed at a position close to the end of the support arm 1, and the support arm 1 is rotatably connected to the connecting frame 2 through the rotating shaft 7. The adjusting rod group 3 includes a fixed frame 8 and an adjusting screw 9. The fixed frame 8 is fixedly connected to the connecting frame 2, and the adjusting screw 9 is located inside the fixed frame 8. One end of the adjusting screw 9 is rotatably connected to the connecting frame 2, and the other end of the adjusting screw 9 is rotatably connected to the fixed frame 8. A movable block 10 is arranged inside the fixed frame 8, and the movable block 10 is threadedly connected to the adjusting screw 9. The ends of the movable block 10 are movably connected to the end of the support arm 1 at the same end through a connecting rod 11.

[0037] It can be known that by rotating the adjusting screw 9, the movable block 10 can be driven to move inside the fixed frame 8. During the movement of the movable block 10, the end of the support arm 1 can be driven to move by the connecting rod 11, so that the support arm 1 can rotate around the rotating shaft 7; when the movable block 10 pushes the connecting rod 11 to drive the end of the support arm 1 to move upward, the distance between the other ends of the two support arms 1 increases, thereby increasing the size of the opening; when the movable block 10 pulls the connecting rod 11 to drive the end of the support arm 1 to move downward, the distance between the other ends of the two support arms 1 decreases, thereby reducing the size of the opening; and thus the distance between the two support arms 1 can be adjusted according to usage requirements to meet the needs of different groups of people.

[0038] The side support frame 4 is arranged at one end of the support arm 1 away from the connecting frame 2, the side support frame 4 is fixedly connected to the support arm 1, and an L-shaped push-pull rod 5 is arranged on the side of the side support frame 4, and the L-shaped push-pull rod 5 is used to adjust the distance between the two ends of the side support frame 4; specifically, the L-shaped push-pull rod 5 is fixedly connected to the upper end of the side surface of the side support frame 4, and a fixing rod 12 is fixed to the lower end of the side surface of the side support frame 4, the lower end of the L-shaped push-pull rod 5 is plug-connected with the fixing rod 12, and the end of the fixing rod 12 is plug-connected with a limiting pin 13, and a positioning through hole is opened on the L-shaped push-pull rod 5, and the number of the positioning through holes is multiple, and the multiple positioning through holes are arranged in a vertical array, and the limiting pin 13 is plug-connected with the positioning through hole.

[0039] It can be known that by pushing and pulling the L-shaped push-pull rod 5 up and down, the distance between the two ends of the side support frame 4 can be driven, so that the upper and lower widths of the opening can be further adjusted according to usage requirements, effectively improving the applicability of the device. After the distance between the two ends of the side support frame 4 is adjusted by pushing and pulling the L-shaped push-pull rod 5 up and down, the movement of the L-shaped push-pull rod 5 is limited by inserting the limit pin 13.

[0040] The protective pad 6 is arranged at a position outside the side support frame 4, and the protective pad 6 is snap-fitted and connected to the side support frame 4; specifically, a snap-fit plug-in block 14 is fixed to one side of the protective pad 6 close to the side support frame 4, and a snap-fit slot 15 is provided at a position of the side support frame 4 corresponding to the snap-fit plug-in block 14, and the snap-fit plug-in block 14 is snap-fitted and connected to the snap-fit slot 15.

[0041] It can be seen that the side support frame 4 can be in contact with the human mouth through the protective pad 6, which plays an effect of protecting the human mouth, reducing the damage of the side support frame 4 to the human mouth, and reducing discomfort.

[0042] Embodiment 2:

[0043] The new type of opener provided in Example 1 is further optimized. Specifically, the material of the protective pad 6 is silicone.

[0044] Through the above structural design, the protective pad 6 is made soft and comfortable.

[0045] Embodiment 3:

[0046] The new type of opener provided in Example 1 is further optimized. Specifically, the side support frame 4 is made of elastic material.

[0047] Through the above structural design, the side support frame 4 can bend along with the rotation of the L-shaped push-pull rod 5 while supporting the corners of the mouth.
