[0024] This specific embodiment is a metal file installation clamping mouth mirror, and its structural diagram is as follows Figures 1-6 As shown, it includes a handle 1, a connecting rod 2 and a mouth mirror 3. The mouth mirror 3 is fixedly connected to the bottom of the handle 1 through the connecting rod 2. A mounting groove 4 and a receiving groove 5 that are interconnected are provided in the middle of the upper end of the handle 1. The mounting groove 4 is located below the receiving groove 5 and the inner diameter of the receiving groove 5 is larger than the inner diameter of the mounting groove 4. A guide groove 8 is provided on one side of the handle 1 at a position corresponding to the mounting groove 4. A driving mechanism is provided inside the mounting groove 4, and a clamping mechanism 9 is provided inside the receiving groove 5.

[0025] By arranging a driving mechanism and a clamping mechanism 9 at the upper end of the handle 1, the driving mechanism can drive the clamping mechanism 9 to move and unfold, and the clamping mechanism 9 can be aligned with the metal file. Then, the driving mechanism can be released to tighten the metal file through the clamping mechanism 9. Finally, the metal file can be taken through the handle 1 and installed on the machine motor.

[0026] Among them, the driving mechanism includes a driving column 10, which is slidably connected to the inner upper end of the mounting groove 4, and a reset spring 13 is fixedly connected between the bottom of the driving column 10 and the inner bottom wall of the mounting groove 4; by arranging the reset spring 13 and the driving column 10, under the action of the reset spring 13, the driving column 10 can always be at the inner lower end of the mounting groove 4 in the absence of external force, so that the clamping mechanism 9 is always inside the storage groove 5.

[0027] In addition, a guide column 11 is fixedly connected to one side of the driving column 10, and the end of the guide column 11 away from the driving column 10 slides through the guide groove 8 and extends to the outside where a push block 12 is fixedly connected; the push block 12 can be pushed upward by the index finger, and the push block 12 can drive the guide column 11 to move upward in the guide groove 8, and the guide column 11 drives the driving column 10 to move upward in the mounting groove 4. At the same time, the driving column 10 can stretch the reset spring 13 when it moves upward.

[0028] In addition, inclined grooves 6 are provided on the inner walls on both sides of the storage groove 5, and an arc-shaped groove 7 is provided on the top of the storage groove 5. The center line of the arc-shaped groove 7 intersects the center lines of the two inclined grooves 6 at right angles. The inclined grooves 6 can guide the inclined block 20. The setting of the arc-shaped groove 7 can limit the non-working end of the metal file after the clamping mechanism 9 tightens and retracts the metal file, thereby avoiding the metal file from being deflected due to loose connection with the machine motor.

[0029] In addition, the clamping mechanism 9 includes a mounting block 14, which is slidably connected to the inside of the receiving groove 5, and the lower surface of the mounting block 14 is fixedly connected to the upper surface of the driving column 10. A sliding groove 15 is provided in the middle of the mounting block 14 and at a position corresponding to the inclined groove 6, and a chamber 16 is provided on the inner bottom wall of the sliding groove 15; the driving column 10 can drive the mounting block 14 to move in the receiving groove 5.

[0030] In addition, there are two L-shaped plates 17 slidably connected to the inside of the slide 15, the horizontal ends of the two L-shaped plates 17 are in contact with each other, and the lower surfaces of the horizontal ends of the two L-shaped plates 17 away from the vertical ends are fixedly connected to the limit plates 18, and the limit plates 18 are slidably connected to the inside of the chamber 16. The vertical ends of the two L-shaped plates 17 are located above the mounting block 14 and are fixedly connected to the clamping plate 21. The middle part of the side where the vertical ends of the two L-shaped plates 17 are away from each other is fixedly connected to a connecting column 19, and the end of the connecting column 19 away from the L-shaped plate 17 is fixedly connected to an inclined block 20; the two A spring 22 is fixedly connected between the middle parts of the side where the vertical ends of the L-shaped plate 17 are close to each other, and an arc-shaped clamping groove 23 is provided on the upper ends of the two clamping plates 21 on the side where they are close to each other. The inclined surface of the inclined block 20 is slidably connected to the inclined surface of the inclined groove 6. In this way, when the driving column 10 drives the mounting block 14 to move upward, the mounting block 14 drives the various components thereon to move upward, so that the inclined block 20 can move upward. Since the inclined groove 6 is inclined outward on both sides, the inclined block 20 on the L-shaped plate 17 gradually loses the restriction of the inclined groove 6 during the upward movement, so that The spring 22 can be stretched and reset, and at the same time, the two ends of the spring 22 can simultaneously drive the L-shaped plates 17 on the same side away from each other, so that the connecting column 19 and the inclined block 20 move outward, so that the inclined block 20 is always in contact with the inclined groove 6. When the two L-shaped plates 17 move upward and away from each other, they can drive the two clamping plates 21 to move upward and away from each other, so that the upper end of the clamping plate 21 is exposed to the handle 1, and the distance between the two clamping plates 21 is greater than the diameter of the metal file. In this way, the two clamping plates 21 can be placed on both sides of the metal file, and then slowly When the index finger is released, the return spring 13 loses its restriction and retracts downward, thereby driving the driving column 10 to move downward. The driving column 10 drives the mounting block 14 to move downward and reset, so that the inclined block 20 moves downward along the inclined groove 6 and approaches inward, so that the two L-shaped plates 17 move downward and approach each other, so that the spring 22 is compressed, so that the two clamping plates 21 approach each other and tighten the metal file in the clamping groove 23 until the non-working end of the metal file contacts the arc groove 7; when there is no external force, the clamping plate 21 is located in the receiving groove 5.

[0031] Working principle: when in use, pick up the upper end of the handle 1 with your hand and make a pen-holding gesture, then match the upper end of the handle 1 with the metal file, and then push the push block 12 with your index finger. The push block 12 can drive the guide column 11 to move upward in the guide groove 8, and the guide column 11 drives the driving column 10 to move upward in the mounting groove 4. At the same time, when the driving column 10 moves upward, it can stretch the reset spring 13 and adjust the mounting block 14 to move upward. The mounting block 14 drives the various components thereon to move upward, so that the inclined block 20 can move upward. Since the inclined groove 6 is tilted upward and outward, the inclined block 20 on the L-shaped plate 17 gradually loses the restriction of the inclined groove 6 during the upward movement of the L-shaped plate 17, so that the spring 22 can stretch and reset. At the same time, the two ends of the spring 22 can simultaneously drive the L-shaped plates 17 on the same side away from each other, thereby causing the connecting column 19 and the inclined block 20 to move outward, so that the inclined block 20 is always in the inclined groove 6, when the two L-shaped plates 17 move upward and away from each other, they can drive the two clamping plates 21 to move upward and away from each other, so that the upper ends of the clamping plates 21 are exposed from the handle 1, and the distance between the two clamping plates 21 is greater than the diameter of the metal file, so that the two clamping plates 21 can be placed on both sides of the metal file, and then the index finger is slowly released. At this time, the return spring 13 loses its restriction and retracts downward, thereby driving the driving column 10 to move downward, and the driving column 10 drives the mounting block 14 to move downward and reset, so that the inclined block 20 moves downward along the inclined groove 6 and approaches inward, so that the two L-shaped plates 17 move downward and approach each other, so that the spring 22 is compressed, so that the two clamping plates 21 approach each other and tighten the metal file in the clamping groove 23 until the non-working end of the metal file contacts the arc groove 7, and finally the metal file is installed with the machine motor.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
