[0018] 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.

[0019] like Figure 1-4As shown, the utility model provides a technical solution: including a support component 1, the top and bottom ends of the support component 1 are each provided with a bearing component 2, the support component 1 includes a threaded rod 101, one end of the threaded rod 101 is fixedly installed with a turning handle 102, both ends of the rod body of the threaded rod 101 are threadedly sleeved with a threaded collar 103, the top and bottom ends of the two threaded collars 103 are fixedly installed with a transmission rotating seat 104, the rotating grooves of the four transmission rotating seats 104 are rotatably connected with a transmission push rod 105, the other ends of the four transmission push rods 105 are rotatably installed with a push rotating seat 106, and the two push rotating seats 106 located at the same height are fixedly connected together, and the threaded rod 101 is a double-headed screw, and the thread rotation directions at both ends are arranged in opposite directions;

[0020] The threaded collar 103 includes a first half collar 107 and a second half collar 108. Both threaded collars 103 are composed of a first half collar 107 and a second half collar 108. A vertical shaft 109 is fixedly installed on one side of the top of the first half collar 107. A threaded rotating rod 110 is rotatably installed on the other side of the top of the first half collar 107. A through hole and a threaded hole are respectively opened on both sides of the top surface of the second half collar 108. The vertical shaft 109 is movably inserted in the through hole. The threaded rotating rod 110 is rotatably installed on the other side of the top of the first half collar 107. The rod 110 is threadedly inserted into the threaded opening and manually turned to the turning handle 102. The turning of the turning handle 102 can drive the two threaded rings 103 to approach each other synchronously. As the two threaded rings 103 approach each other, one end of the transmission rod 105 will be driven to approach each other, and then the other end of the transmission rod 105 will be rotated and installed on the rotating seat 106. By moving the rotating seat 106, the two bearing components 2 can be moved away from each other, so that the patient's oral cavity can be conveniently expanded and play a supporting role in the subsequent process.

[0021] In this embodiment, the bearing assembly 2 includes a mounting support plate 201 , a concave seat 202 is fixedly mounted on the front edge of the top surface of the mounting support plate 201 , and a bite groove 203 is formed on the top surface of the concave seat 202 .

[0022] At the same time, a support plate 204 is slidably installed in the occlusal groove 203, and a cylinder 205 is fixedly installed at the four corners of the bottom surface of the support plate 204. A circular cavity is opened in the cylinder 205, and a piston rod 207 is movably inserted in the circular cavity. A spring 206 is fixedly installed on the top of the piston rod 207, and the other end of the spring 206 is fixedly connected to the top surface of the circular cavity. The bottom end of the piston rod 207 is fixedly connected to the bottom surface of the occlusal groove 203. When the patient is biting, the spring 206 provides a certain buffer space for the biting, so that the patient can adjust the mouth within a certain space, which can avoid the situation where the patient's mouth can only maintain one state when the expansion device is supported, causing oral discomfort.

[0023] The mounting support plate 201 is fixedly connected to the two movable rotating seats 106 of the same height, and the two bearing components 2 are symmetrically arranged.

[0024] When in use, the patient first opens his mouth, then inserts the two bearing components 2 into the oral cavity, and bites on the bearing components 2 respectively through the upper and lower teeth, that is, bites into the corresponding bite grooves 203 through the teeth, and then manually turns to the turning handle 102. The turning handle 102 can drive the two threaded rings 103 to approach each other synchronously. As the two threaded rings 103 approach each other, one end of the transmission rod 105 will be driven to approach each other, and then the other end of the transmission rod 105 will be rotated and installed to move the moving rotating seat 106. By moving the moving rotating seat 106, the two bearing components 2 can be moved away from each other, so that the patient's oral cavity can be conveniently expanded, and it can play a supporting effect in the subsequent process. At the same time, when the patient bites, the spring 2 06 provides a certain buffer space for occlusion, allowing the patient to adjust the mouth within a certain space, and can avoid the situation where the patient's mouth can only maintain one state when the expansion device is supported, causing oral discomfort. After use or when the patient needs to quickly release the expansion due to oral discomfort, the threaded rotating rod 110 can be rotated at the same time. The rotation of the threaded rotating rod 110 can drive the two No. 2 and a half rings 108 to move along the direction of the threaded rotating rod 110, so that the threaded ring 103 can be disconnected from the threaded rod 101, and then the two threaded rings 103 can be quickly moved to both ends under the action of the bite force, so that the two bearing components 2 can disconnect the support for the teeth, and then the expansion device can be conveniently removed from the patient's mouth.

[0025] In summary, the easily adjustable expansion device controls the synchronous movement of the two bearing components 2 to move them away from each other, thereby conveniently expanding the patient's mouth and providing support in the subsequent process. At the same time, when use is completed or the patient needs to quickly release the expansion due to oral discomfort, the threaded rotating rod 110 can be rotated at the same time. The rotation of the threaded rotating rod 110 can drive the two No. 2 and a half rings 108 to move along the direction of the threaded rotating rod 110, thereby disconnecting the threaded ring 103 from the threaded rod 101, and then the two threaded rings 103 can be quickly moved to both ends under the action of the bite force, thereby disconnecting the two bearing components 2 from the teeth, thereby conveniently removing the expansion device from the patient's mouth, which is more practical.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
