DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, an oral support for children, in order to facilitate doctors to keep the opening and closing degree of the oral support unchanged, the utility model includes a first support unit, a second support unit, and a positioning mechanism 6. The first support unit includes a first handle 1 and a first support rod 3 fixedly connected to the first handle 1. The second support unit includes a second handle 2 and a second support rod 4 fixedly connected to the second handle 2. The first handle 1 and the second handle 2 are for hand grasping. The ends of the first support rod 3 and the second support rod 4 are used to extend into the oral cavity. The second support rod 4 is fixedly connected to a rotating shaft 41. The rotating shaft 4 1 passes through the first support rod 3, and the end of the rotating shaft 41 away from the first support rod 3 is fixedly connected with the ratchet 42, and the first support rod 3 can rotate around the rotating shaft 41. The positioning mechanism 6 includes a pawl 61 for engaging with the ratchet 42. The middle part of the pawl 61 is rotatably connected to the first support rod 3, and the end of the pawl 61 away from the ratchet 42 is rotatably connected with the pull rod 62. When the pull rod 62 pulls the pawl 61, one end of the pawl 61 is close to or away from the ratchet 42. The positioning mechanism 6 also includes a limiting ring 63 fixed on the first handle 1, and the pull rod 62 passes through the limiting ring 63.

[0020] Specifically, the method of use is as follows: when the first handle 1 and the second handle 2 are pinched by hand and brought close to each other, the ends of the corresponding first support rod 3 and the second support rod 4 are moved away from each other, and the oral cavity can be stretched open. Pull the pull rod 62 to make the pawl 61 engage with the ratchet 42, and the pawl 61 can only move along the tooth bud direction of the ratchet 42. When the first handle 1 and the second handle 2 are close to each other, the pawl 61 is not blocked. When the first handle 1 and the second handle 2 tend to move away from each other, the pawl 61 is stuck by the ratchet 42. Therefore, when the pawl 61 engages with the ratchet 42, the ends of the first support rod 3 and the second support rod 4 can maintain the opening and closing degree unchanged. Furthermore, when the opening and closing degree of the ends of the first support rod 3 and the second support rod 4 is the largest, the doctor does not need to devote energy to controlling the gripping force of the hand.

[0021] Furthermore, in order to increase the resistance of the pull rod 62 when it moves and prevent it from accidentally sliding, the utility model also provides a movable groove 11 on the first handle 1, and a sliding seat 7 is slidably connected in the movable groove 11, and a friction block 73 for pressing on the pull rod 62 is fixedly connected to the sliding seat 7.

[0022] Furthermore, the first handle 1 is fixedly connected to an adjustment seat 12, and a bolt 13 is threadedly connected to the adjustment seat 12. One end of the bolt 13 away from the adjustment seat 12 extends into the movable groove 11, and the end of the bolt 13 is used to press on the sliding seat 7. The pressure applied to the sliding seat 7 is controlled by screwing the bolt 13, so as to adjust the friction between the friction block 73 and the pull rod 62.

[0023] Furthermore, the sliding seat 7 includes a sliding block 71 located in the movable groove 11 , and two ends of the sliding block 71 are fixedly connected to sliding plates 72 located outside the movable groove 11 .

[0024] Furthermore, the ends of the first support rod 3 and the second support rod 4, that is, the ends of the first support rod 3 and the second support rod 4 away from the first handle 1 and the second handle 2 are fixedly connected with a dental tray 5, and the dental tray 5 is made of soft material.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
