[0030] Please see Figure 1-8 This utility model provides a technical solution:
[0031] A denture fixing bracket for denture processing includes a rod portion 1, a driving portion 2, and a clamping portion 3. The rod portion 1 includes a rod housing 11, with an upwardly opening rod groove 12 on the inner side of the rod housing 11.

A drive unit 2 is installed at the rod 1. The drive unit 2 includes a guide seat 22 that is slidably connected to the rod groove 12. An elastic pull rope 21 is fixedly connected to the lower side of the guide seat 22. The lower end of the elastic pull rope 21 is fixedly connected to the lower inner wall of the rod groove 12. Guide grooves 23 that are aligned with the sliding opening 13 are opened on both the left and right sides of the guide seat 22. A pressure block 24 located inside the sliding opening 13 is slidably connected to the inner side of the guide groove 23. A conical groove 25 with an upward opening is opened on the inner side of the guide seat 22. A number of guide members 26 arranged at equal angles are provided in the conical groove 25. A linkage bar 27 is fixedly connected to the upper side of the guide member 26. The upper end of the linkage bar 27 passes through the guide channel 34 and is fixedly connected to the clamping block 35.
[0032] The conical groove 25 has a structure that is wider at the top and narrower at the bottom. The curved surfaces of the guide member 26 are all in contact with the inner wall of the conical groove 25. A gap is provided between the guide member 26 and the lower inner wall of the conical groove 25. This arrangement allows the conical groove 25 to move upward, and the upward movement of the conical groove 25 will push the guide member 26 to move. The pressure guide block 24 consists of a pinching block and a guide bar. The guide groove 23 consists of an inclined groove and a channel. The guide bar of the pressure guide block 24 is located inside the channel of the guide groove 23. This arrangement allows the guide groove 23 and the pressure guide block 24 to move together. The pressure guide block 24 protrudes from the outer curved surface of the rod shell 11. This design facilitates the pressing of the pressure guide block 24 by the staff; each of the connecting bars 27 near the mounting groove 32 has a storage groove 28, and the storage grooves 28 are all located inside the guide channel 34. A spring 29 is installed inside each storage groove 28, and the end of the spring 29 away from the storage groove 28 is fixedly connected to the inner wall of the guide channel 34. This design allows the storage groove 28 to store the spring 29, and the spring 29 to reset the connecting bar 27 after displacement; the clamping block 35 consists of a base block and a rubber damping pad, and the rubber damping pad of the clamping block 35... All are positioned close to the mounting groove 32. The rubber damping pads of the clamping blocks 35 have a concave-convex structure, which improves the clamping performance of the clamping blocks 35. The outer end faces of the clamping blocks 35 are all in contact with the inner wall of the guide 33, which improves the stability of the clamping blocks 35 during displacement. A toggle part 4 is installed at the rod 1. The toggle part 4 includes a rotating sleeve 41 that is rotatably connected to the base sleeve 14. A middle connecting strip 42 is fixedly connected to the rear side of the rotating sleeve 41. A toggle sleeve 43 that is sleeved on the outside of the rod shell 11 is fixedly connected to the lower side of the middle connecting strip 42. The front side of the rotating sleeve 41 is rotated by a rotating component. A transparent baffle 5 is connected to the moving part 4. This setting allows the moving part 4 to adjust the displacement of the transparent baffle 5. The transparent baffle 5 can prevent the powder generated during the grinding process from flying onto the face of the operator, thereby avoiding affecting the processing operation. The transparent baffle 5 is located on the lower side of the clamping part 3. The transparent baffle 5 is set close to the clamping part 3. This setting allows the transparent baffle 5 to be flipped up and block the front side of the clamping part 3. The dial sleeve 43 is composed of an upper connecting ring and a lower convex sleeve. The convex sleeve surface of the dial sleeve 43 is provided with several convex strips. This setting makes it convenient for the operator to rotate the dial sleeve 43.
[0033] Workflow: The operation procedure for using the denture fixation bracket is as follows: First, insert a portion of the individual denture into the mounting slot 32. Then, the operator holds the rod 1 with one hand and presses the guide blocks 24 on both sides using the thumb and middle finger. As a group of guide blocks 24 move towards each other, and with the guiding engagement between the guide blocks 24 and the guide groove 23, the guide seat 22 and the conical groove 25 are forced to move upward, thereby applying pressure to each guide component 26. Under the guiding action of the conical groove 25, the guide component 26 drives the connecting bar 27 and the clamping block 3. 5. The opposing displacement securely clamps the denture inserted into the slot 32, completing the clamping operation. At this time, the operator's other hand can hold the grinder to grind and smooth the exposed denture surface. When the operator needs to adjust the clamping position, the pressure block 24 is released. As the guide seat 22 moves upward, the unfolded elastic rope 21 automatically retracts, causing the guide seat 22 to move downward and reset. This action resets the pressure block 24 through the transmission mechanism. At the same time, the guide component, no longer restricted by the pressure of the guide seat 22 and the conical groove 25,... 26. The linkage 27 and clamping block 35 will reset under the expansion force of the spring 29, thereby releasing the clamping of the denture. At this time, the operator can adjust the position of the denture and repeat the above clamping operation to clamp the denture again for continued polishing. During the processing, the operator can flip up the transparent baffle 5 to prevent the powder generated during polishing from hitting the operator's face, thus avoiding affecting the processing operation. In addition, the operator can also, as needed, turn the lever 43 with the index finger to drive the connecting bar 42 and the rotating sleeve 41 to rotate. The position of the transparent baffle 5 can be adjusted by rotating the rotating sleeve 41 to keep it effective. This design enables the denture fixing bracket to quickly, flexibly and stably fix a single denture, increasing the distance between the hand and the polisher so that the operator can polish a single denture. It effectively solves the problem that manual polishing of a single denture is prone to injury, while existing denture fixing brackets are generally not suitable for flexible and quick fixation of a single denture.
[0034] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
