Based on the above, it can be known that this children's oral cavity mouth gag, when in actual use, although can expand the location to the oral cavity, establish at casing and second fixed plate and just in front of children's face again, can shelter from children's face, and then can not let children's oral cavity expose before medical personnel completely, consequently be inconvenient for medical personnel to the operation that nursing was carried out to children's oral cavity. Disclosure of utility model The utility model aims to solve the defect that the operation of medical staff is shielded when the children oral cavity opener in the prior art is used. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a children oral cavity mouth gag, includes two opening mechanism, opening mechanism includes first dead lever, be fixed with first fixed plate on the first dead lever, it is equipped with the second dead lever to rotate on the first dead lever, the second dead lever with all be fixed with the second fixed plate on the first dead lever, every all be fixed with the layer board on the second fixed plate, two the layer board symmetry sets up, first dead lever with be equipped with positioning mechanism jointly between the second dead lever. Preferably, the supporting plate is of an inverted 匚 -shaped structure, and the two second fixing plates are arranged between the two supporting plates. Preferably, the positioning mechanism comprises an arc-shaped limiting rod, the limiting rod is fixed on the first fixing rod, an arc-shaped hole is formed in the limiting rod in a penetrating mode, the second fixing rod penetrates through the hole, a plurality of inserting holes are symmetrically formed in the limiting rod on two sides of the hole in a penetrating mode, and positioning assemblies are jointly inserted between the inserting holes and the second fixing rod. Preferably, the positioning assembly comprises a stop lever, a plug-in rod is fixed on the stop lever, a rubber sleeve is sleeved and fixed on the plug-in rod, and the plug-in rod and the rubber sleeve penetrate through two of the plug-in holes and the second fixing rod. Preferably, the two limit rods are jointly fixed with a connecting mechanism. Preferably, the connecting mechanism comprises two connecting plates, the two connecting plates are respectively fixed on the two limiting rods, and an adjusting assembly is jointly fixed between the two connecting plates. Preferably, the adjusting component comprises two connecting rods, the two connecting rods are respectively fixed on the two connecting plates, and the two connecting rods are sleeved with cylinders through common threads. The children oral cavity opener has the beneficial effects that when the children oral cavity opener is used, four supporting plates can be used simultaneously, two supporting plates can be used, so that when the children oral cavity is supported, the parts which need to be operated during nursing are not shielded, the operation of medical staff is facilitated, and meanwhile, the effect of children oral cavity nursing can be ensured.
