[0020] Embodiment:
[0021] Please refer to Figures 1-3The dental implant handle in this solution can be angle-adjusted, which is more adaptable than the traditional straight screwdriver handle and can meet most dental implant needs.
[0022] A dental implant clamp handle includes a handle 1, which consists of a torque wrench part 2 and an angle adjustment part 3; the angle adjustment part 3 is located at the left end of the torque wrench part 2; the angle adjustment part 3 includes an adjustment ring 5, a fixing ring 7 and an inner ring 8;
[0023] The left side of the angle adjustment section 3 is provided with a U-shaped adjustment groove 4 opening to the left. Two adjustment rings 5 are installed inside the adjustment groove 4, with an installation gap reserved between the two adjustment rings 5 (as shown in the attached figure). Figure 1 and 2 In the middle, the gap between the two adjusting rings 5), the upper and lower outer walls of the angle adjusting part 3 are screwed with locking bolts 6, and the locking bolts 6 are connected to the adjusting rings 5 inward;
[0024] A fixed ring 7 is installed on the left side of the adjusting ring 5. The fixed ring 7 is fixed together with the adjusting ring 5 (essentially a single piece). When the adjusting ring 5 rotates, the fixed ring 7 also rotates synchronously. The adjusting ring 5 is equivalent to the pivot of the fixed ring 7. The angle of the fixed ring 7 is adjusted by the adjusting ring 5. An inner ring 8 is rotatably installed inside the fixed ring 7. A gear ring 11 is sleeved on the outer wall of the inner ring 8. The adjusting ring 5 can rotate in the adjusting groove 4 to achieve the angle adjustment of the fixed ring 7 in the left and right directions. After adjustment to the position, tighten the locking bolts 6 on both sides. The locking bolts 6 are fixed by the screw connection between the angle adjusting part 3 and the adjusting ring 5, which is very convenient.
[0025] A ratchet half-ring 12 is installed between the two adjusting rings 5. The ratchet half-ring 12 is close to the fixed ring 7 to the left, and a ratchet is provided on the side of the ratchet half-ring 12 close to the fixed ring 7. A movable groove (not shown in the figure) is opened at the connection between the fixed ring 7 and the adjusting ring 5. The gear ring 11 and the ratchet half-ring 12 are both located in the movable groove and mesh with each other.
[0026] A connecting rod 13 is provided at the right end of the ratchet half-ring 12. The connecting rod 13 extends to the right into the inner cavity of the torque wrench part 2, and the connecting rod 13 is connected to the pivot block inside the torque wrench part 2. The structure of the torque wrench part 2 is the same as that of a conventional dental implant torque wrench, and the drive and adjustment structures are also the same (not described here). The pivot block inside the torque wrench part 2 is connected to the connecting rod 13. The connecting rod 13 pries the inner ring 8 to rotate, and then the inner ring 8 drives the screwdriver 10 to rotate. A hexagonal locking groove 9 is provided in the middle of the inner ring 8, and the screwdriver 10 is locked in the hexagonal locking groove 9. When it is necessary to adjust the angle of the fixed ring 7, the torque of the torque wrench part 2 is adjusted. At this time, the connection between the ratchet half-ring 12 and the gear ring 11 is relatively loose, and it is extremely convenient and unrestricted to adjust the angle of the fixed ring 7.
[0027] The working principle of this solution is as follows:
[0028] Angle adjustment part 3 is located at the left end of torque wrench part 2. There is a U-shaped adjustment groove 4 with an opening to the left on the left side of angle adjustment part 3. Two adjustment rings 5 are installed in the groove, with an installation gap between them, so that the adjustment rings 5 can rotate in the adjustment groove 4.
[0029] When the angle needs to be adjusted, rotate the adjusting ring 5. Since the adjusting ring 5 has a fixed ring 7 installed on its left side, and the fixed ring 7 has an inner ring 8 installed inside it, the rotation of the adjusting ring 5 will drive the fixed ring 7 to achieve the angle adjustment in the left and right directions.
[0030] After adjusting to the appropriate angle position, tighten the locking bolts 6 on the upper and lower outer walls of the angle adjustment part 3. Because the locking bolts 6 are connected to the adjustment ring 5 inward and screwed to the angle adjustment part 3, the adjustment ring 5 is fixed through this screwed connection, thereby fixing the angle.
[0031] The structure of the torque wrench part 2 is the same as that of a conventional dental implant torque wrench. Its drive and adjustment structure can generate torque, which will not be described in detail here. The pivot block inside the torque wrench part 2 is connected to the connecting rod 13. When the torque wrench part 2 is working, the inner ring 8 is rotated by the connecting rod 13. Because the outer wall of the inner ring 8 is fitted with a gear ring 11, and the gear ring 11 meshes with the ratchet half ring 12, and the ratchet half ring 12 is connected to the pivot block inside the torque wrench part 2 through the connecting rod 13, the torque can be transmitted to the inner ring 8 through this meshing relationship.
[0032] The inner ring 8 has a hexagonal snap-fit groove 9 in the middle, and the screwdriver 10 is snapped into the hexagonal snap-fit groove 9. Therefore, the rotation of the inner ring 8 will drive the screwdriver 10 to rotate.
[0033] The ratchet half-ring 12 is designed to work with the gear ring 11. When the torque wrench part 2 transmits torque through the connecting rod 13, the meshing of the ratchet half-ring 12 and the gear ring 11 can more effectively transmit the torque to the inner ring 8.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be considered as limiting the scope of the claims.
[0035] 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.
