[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1As shown, the utility model provides an embodiment of a pet mouth opener, comprising: a shell, the shell consisting of an upper shell and a lower shell sleeved outside the upper shell, tooth contact plates are arranged at the ends of the upper shell and the lower shell, the tooth contact plates include an upper tooth contact plate 1 and a lower tooth contact plate 5, and the occlusal surfaces of the upper tooth contact plate 1 and the lower tooth contact plate 5 are both concave with rounded edges.

[0024] The inventors found that the lengths of teeth in the mouths of pets vary greatly, and their arrangement paths are in the shape of a triangular cone. The existing pet openers with metal springs on the market have a large expansion range, and their shapes and materials are sharp, which can easily cause secondary damage to the mouth. The occlusal surface of the tooth contact plate provided in the present application is a concave tooth contact plate with rounded edges. Its shape better fits the morphological characteristics of canine teeth, protects the pet's oral cavity from scratches, is safer and healthier, has a stable fixed support function, is convenient for taking and replacing positions, and improves the efficiency of doctors' consultations.

[0025] Moreover, if Figure 2 As shown, the tooth contact plate also has a slot, and the slot is connected with a connector 10, and the connector 10 is fixedly installed at the end of the shell, so that the user can disassemble and replace the tooth contact plate, thereby having the characteristics of replaceability and independent disinfection, solving the pain points of the one-piece mouth opener that parts cannot be replaced and bacteria can grow, and avoiding cross infection.

[0026] like Figure 3 As shown, a slide rail structure 9 is arranged between the upper shell and the lower shell. The slide rail structure 9 is a concave strip-shaped groove structure, so that the upper shell can slide in the lower shell along the axial direction.

[0027] like Figure 4-Figure 6 As shown, a cavity 11 is provided in the shell, and a pressing piece 2 is fixed on the upper shell. The pressing piece 2 is in the shape of an annular tooth. The teeth of the pressing piece 2 are located in the cavity 11. A slide groove piece 6 is fixed on the inner wall of the pressing piece 2. The slide groove piece 6 is a cylindrical structure with multiple groups of teeth, and a tooth groove is provided between two adjacent groups of teeth. A turntable 7 matching with the teeth of the slide groove piece 6 is provided in the lower shell. The turntable 7 is a disc structure with multiple columns (the upper end is an inclined surface), wherein the outer facade of the column extends out of the tooth groove of the slide groove piece 6, so that the teeth on the pressing piece 2 located on the outer surface of the slide groove piece 6 can contact the column, thereby pushing the turntable 7. The turntable 7 is connected to a spring 8, one end of which is fixed to the lower shell, and the other end of the spring 8 is fixed to the turntable 7. When the pressing piece 2 is pressed down, the spring 8 will undergo elastic deformation to provide an upward force for the turntable 7.

[0028] In this embodiment, the operator presses the pressing piece 2 downward, and the pressing piece 2 is pushed by an external force, so that the teeth of the slide member 6 press downward on the column on the turntable 7, so that the turntable 7 rotates. When the turntable 7 is disengaged from the tooth groove of the slide member 6, the pressing piece 2 applies a radial force to the inclined surface of the column on the turntable 7, so that the turntable 7 rotates until the turntable 7 is engaged with the teeth of the slide member 6. The engagement state of the components is changed by pressing the pressing piece 2, and the mouth opening height can be repeatedly changed, which is convenient for the doctor to choose to lower the mouth opening height or temporarily remove the mouth opener to restore normal blood flow according to clinical needs, effectively improving the flexibility of medical treatment and the efficiency of diagnosis and treatment.

[0029] Traditional mouth openers lack time indication. Maintaining the mouth open at the same height for too long during surgery will affect the blood flow in the pet's maxillary artery, which can easily cause cerebral ischemia and blindness. In the present application, a power switch 3 is provided on the lower shell, and a number of indicator lights 4 are provided below the power switch 3. The indicator lights 4 are connected to the timing module. The indicator lights 4 and the timing module form a prompting device, which provides feedback every 5 minutes (i.e., one indicator light 4 lights up every 5 minutes, and six indicator lights 4 are provided, and a full light means 30 minutes), which is used to prompt the doctor that the mouth opening time has reached a dangerous value, and it is necessary to lower the shell height or remove the mouth opener to wait for the blood flow in the head to return to normal, so as to avoid using it for too long.

[0030] Working principle: the operator presses the pressing piece 2 downward, and the pressing piece 2 is pushed by an external force, so that the teeth of the slide member 6 press downward the column on the turntable 7, so that the turntable 7 rotates. When the turntable 7 is disengaged from the tooth groove of the slide member 6, the pressing piece 2 applies a radial force to the inclined surface of the column on the turntable 7, so that the turntable 7 rotates until the turntable 7 is meshed with the teeth of the slide member 6. The meshing state of the components can be changed by pressing the pressing piece 2, and the opening height can be repeatedly changed.

[0031] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
