[0017] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] Embodiments of the present invention: such as Figs. 1-3 As shown, an auxiliary tool for installing dental veneers includes a handle 1, one end of which is fixedly connected to an arc-shaped connecting tube 2, and a suction cup 3 is detachably installed at the end of the arc-shaped connecting tube 2. An air extraction structure is provided inside the handle 1 and is connected to the arc-shaped connecting tube 2.

[0019] The handle 1 is a cylindrical handle. The connection between the handle 1 and the arc-shaped connecting tube 2 is smoothly transitioned through the conical section 18. The function of the arc-shaped connecting tube 2 is to make the axis of the suction cup 3 and the axis of the handle 1 have a certain angle, so as to make it easier to operate. In this embodiment, the angle between the axis of the suction cup 3 and the axis of the handle 1 is in the range of 100°-150°, preferably 130°.

[0020] By operating the suction structure, the suction cup 3 can firmly adhere to the dental veneer and can also quickly release the dental veneer. When adhering to the dental veneer, it can effectively ensure the firmness of the adsorption and prevent the dental veneer from falling off.

[0021] Specifically, the air extraction structure includes a piston chamber 4, a rubber piston 5, a piston rod 6, and a drive plate 7. The handle 1 has a piston chamber 4 and a piston rod chamber 8. One end of the piston chamber 4 is connected to the arc-shaped connecting pipe 2, and the other end of the piston chamber 4 is connected to the piston rod chamber 8. The rubber piston 5 is installed in the piston chamber 4. One end of the piston rod 6 is fixedly connected to the rubber piston 5, and the other end of the piston rod 6 is inserted into the piston rod chamber 8.

[0022] When piston rod 6 pulls rubber piston 5, rubber piston 5 moves backward, and the circumferential wall of rubber piston 5 fits tightly against piston cavity 4. Therefore, rubber piston 5 draws in gas, creating a negative pressure inside suction cup 3, which firmly adheres to the dental veneer. When piston rod 6 pushes rubber piston 5, rubber piston 5 moves forward, pushing the gas and increasing the air pressure inside suction cup 3, causing suction cup 3 to automatically release the dental veneer.

[0023] Furthermore, a through groove 9 is provided on the handle 1. The length of the through groove 9 is the same as the length of the piston rod cavity 8. The through groove 9 communicates with the piston rod cavity 8. A connecting rod 10 is slidably installed in the through groove 9. One end of the connecting rod 10 is fixedly connected to the tail end of the piston rod 6, and the other end of the connecting rod 10 is fixedly connected to the drive plate 7.

[0024] The length of the drive plate 7 is twice the length of the through groove 9. The drive plate 7 is an arc-shaped plate, and several anti-slip protrusions 11 are formed on the surface of the drive plate 7.

[0025] The length of the drive plate 7 is twice the length of the through groove 9. The connecting rod 10 is fixedly connected to the middle position of the drive plate 7. In this way, no matter where the connecting rod 10 is located in the through groove 9, the drive plate 7 always covers the through groove 9, which can effectively prevent dust from entering the piston rod cavity 8.

[0026] In a preferred embodiment, a rubber ring can also be provided on the bottom surface of the drive board 7 to further protect it from water and dust.

[0027] Furthermore, a light-shielding plate 12 is fitted onto the arc-shaped connecting tube 2, and two ultraviolet LED lights 13 are fixed on the light-shielding plate 12. An LED driver 14 and a battery 15 are installed inside the handle 1. A switch 16 is installed on the end of the handle 1 near the arc-shaped connecting tube 2, and an end cap 19 is threaded to the tail end of the handle 1. The battery 15 can be quickly replaced by opening the end cap 19. A rubber ring 17 is fixed inside the mounting hole of the light-shielding plate 12.

[0028] The UV LED light 13, LED driver 14, battery 15, and switch 16 are all commercially available products and can be purchased directly. The UV LED light 13 is used to illuminate the dental veneers, allowing the adhesive used to bond the veneers to cure quickly. The light shield 12 is used to protect the operator's eyes from UV light damage.

[0029] The working principle of this invention is as follows: When in use, the suction cup 3 is brought into contact with the dental veneer, and the drive plate 7 is pulled backward. The drive plate 7 moves backward along with the piston rod 6 and the rubber piston 5 through the connecting rod 10. The rubber piston 5 draws in gas, creating a negative pressure inside the suction cup 3, which then firmly adheres to the dental veneer.

[0030] The dental veneer is then aligned with the tooth, which has been pre-applied with adhesive. After adjusting the position of the veneer, switch 16 is pressed. Battery 15 powers LED driver 14, which in turn drives UV LED 13 to emit light, illuminating the veneer. During illumination, light shield 12 blocks the light to prevent eye damage to the operator. Once the adhesive has cured, switch 16 turns off the UV LED 13. Then, drive plate 7 is pushed forward. Drive plate 7 moves forward via connecting rod 10, carrying piston rod 6 and rubber piston 5. Rubber piston 5 pushes gas, increasing the air pressure inside suction cup 3, which then automatically releases the dental veneer.

[0031] In another preferred embodiment, a return spring (not shown in the figure) is installed in the piston rod cavity 8. After the dental veneer has cured, the drive plate 7 is released, and the return spring pushes the piston rod 6 forward to realize the automatic release of the dental veneer.

[0032] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
