Example 1:

an oral training opening and closing device can help a patient to perform oral training so as to help the patient to solve fatigue and pain caused by functional exercise, thereby improving the life quality of the patient, and is particularly arranged into the following structures as shown in figures 1-7:

the oral training opening and closing device comprises a straight rod-shaped adjusting rod 2, a mounting frame 3, an L-shaped first working support arm 5, an L-shaped second working support arm 6, an upper bite block 7 and a lower bite block 8. The tail end of the adjusting rod 2 is provided with a flat operating handle 1 for convenient operation, and the head end of the adjusting rod 2 is provided with a conical head for improving the contact surface with the first working support arm 5 and the second working support arm 6. Go up bite-block 7 and bite-block 8 and be the same silica gel structure, wherein go up bite-block 7 and include the bottom plate 71 of U-shaped, the notch of bottom plate 71 is towards the head of oral cavity training opener, and the outside edge of bottom plate 71 is provided with baffle 72, and baffle 72 is used for blocking the tooth, avoids this oral cavity training opener to stretch into too much in the oral cavity.

The tail part of the first working support arm 5 is shorter, the head part of the first working support arm is longer, and the opening of the first working support arm 5 faces to the left side; the second working arm 6 has a shorter tail and a longer head, and the opening of the second working arm 6 faces to the right. A first through hole 31 which is vertically communicated is formed in the middle of the mounting frame 3, the left end of the mounting frame 3 is hinged with the left end of the tail of the first working support arm 5, and the head of the first working support arm 5 is detachably connected with the upper dental pad 7 through a rubber sleeve; the right end of the mounting rack 3 is hinged with the right end of the tail part of the second working support arm 6, and the head part of the second working support arm 6 is detachably connected with the lower bite block 8 through a rubber sleeve.

The adjusting rod 2 is movably inserted into a first through hole 31 formed in the middle of the mounting frame 3, and the adjusting rod 2 can move along the axial direction of the first through hole 31 and also can rotate along the circumferential direction of the first through hole 31. In this embodiment, the adjusting rod 2 is a screw rod, the first through hole 31 is a screw hole, the adjusting rod 2 is screwed with the first through hole 31, and the head end of the adjusting rod 2 passes through the first through hole 31 and abuts against the tails of the first working support arm 5 and the second working support arm 6. Hold between the fingers operating handle 1 rotatable regulation pole 2 through the hand, the length that first through-hole 31 was stretched out to adjustable regulation pole 2 head end can support to lean on first work support arm 5 and second work support arm 6 to use respective pin joint to rotate as the center when adjusting pole 2 extension, makes first work support arm 5 and second work support arm 6 overturn in order to increase the angle that opens and shuts of bite-block 7 and bite-block 8 down towards left side and right side respectively. Wherein, the maximum opening and closing distance of the first working arm 5 and the second working arm 6 should be controlled within 4 cm.

Preferably, the head of the first working arm 5 has a thickness which is less at the leading end than at the trailing end. The thickness of the head end of the head part of the second working arm 6 is smaller than that of the tail end, and the head end of the head part of the working arm with the smaller thickness can enable the upper bite block 7 and the lower bite block 8 to have smaller thickness when being folded, so that the working arm can be put into the oral cavity more easily.

The adjusting rod 2 is abutted with the tails of the first working support arm 5 and the second working support arm 6 through the head end extending out of the first through hole 31, so that the patient can complete the training through the bearable opening angle. The patient can put into the oral cavity with the oral cavity training ware that opens and shuts and bite on bite block 7 and bite block 8 down with upper and lower tooth when closed, and the accessible is adjusted the extension length of pole 2 and is changed on bite block 7 and the angle that opens and shuts of bite block 8 down and accomplish the oral cavity training that opens and shuts. Go up bite-block 7 and bite-block 8 down and can provide more tooth pressfitting areas, the atress of dispersion tooth to help the patient to solve its tired sense and the painful sense that appears in the function exercise to a certain extent, obtain better use travelling comfort, improve patient's quality of life.

Example 2:

this embodiment is further optimized on the basis of above-mentioned embodiment, and further for better realization the utility model discloses, adopt the following structure that sets up very much:

the adjusting rod 2 in this embodiment is different from the adjusting rod in embodiment 1, the adjusting rod 2 in this embodiment is configured as a polished rod, two protruding blocks 21 are disposed at the rod section of the adjusting rod 2, and the two protruding blocks 21 are symmetrically disposed. The first through hole 31 is a screw hole. A hollow stud 4 is arranged in the first through hole 31, an external thread is arranged on the outer wall of the hollow stud 4, and the hollow stud 4 is screwed in the first through hole 31. The middle part of the hollow stud 4 is provided with a second through hole 41 which is through up and down, the hole wall of the second through hole 41 is provided with a horizontal ring groove 42 and two sliding grooves 43 which vertically extend along the axial direction and are communicated with the ring groove 42, the sliding grooves 43 form a gap at the end part of the tail end of the hollow stud 4, and two stopping blocks 44 are respectively arranged at two positions in the ring groove 42 which are staggered with the sliding grooves 43. The adjusting rod 2 is movably inserted into the second through hole 41, and the projection 21 is movably arranged in the ring groove 42.

When the adjusting rod 2 is rotated forward, the convex block 21 can abut against the corresponding stop block 44 to drive the hollow stud 4 to rotate and move towards the first working support arm 5 so as to increase the length of the head end of the adjusting rod 2 extending out of the first through hole 31; the adjustment rod 2 is reversed to align the protrusion 21 with the sliding slot 43, and the adjustment rod 2 is pulled to withdraw the protrusion 21 from the hollow stud 4 along the sliding slot 43. The forward rotation adjusting rod 2 can increase the length of the head end of the adjusting rod 2 extending out of the first through hole 31, and the reverse rotation adjusting rod 2 can enable the adjusting rod 2 to be drawn out of the hollow stud 4, so that the effect of the adjusting rod 2 on the first working support arm 5 and the second working support arm 6 can be quickly canceled when a patient feels fatigue or pain, and the upper bite block 7 and the lower bite block 8 can be quickly folded.

Preferably, the length of the hollow stud 4 is smaller than the length of the first through hole 31, so that the hollow stud 4 can not extend out of or extend out of the first through hole 31 to a small extent, and the distance between the first working arm 5 and the second working arm 6 when the working arms are folded is as small as possible.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
