[0002] The root canal preparation machine is a device used for dental root canal treatment. It is mainly used to remove pulp tissue and expand the root canal to facilitate root canal treatment. The working principle of the root canal preparation machine mainly includes two aspects: rotation and vibration. The root canal preparation machine is driven by an electric motor to rotate in the pulp cavity, thereby removing necrotic tissue, diseased tissue and bacterial infection in the pulp cavity. At the same time, the root canal preparation machine generates high-frequency vibration while rotating, which increases the contact area between the preparation machine and the inner wall of the pulp cavity and improves the working efficiency of the preparation machine.

[0003] After long-term use, the root canal preparation machine needs to be tested for its speed and power to see if it meets the standards. However, the root canal preparation machine and the dynamometer are difficult to connect because the outer diameter of the shaft at the input end of the dynamometer is larger than the inner diameter of the output port of the root canal preparation machine. The two cannot be connected, so a special clamp is needed to connect the two. Utility Model Content

[0027] In this embodiment, the dynamometer 10 and the root canal preparation machine 30 are both prior art and will not be described in detail here. The working principle of the root canal preparation machine 30 mainly includes two aspects: rotation and vibration. The root canal preparation device is driven to rotate by an electric motor so that it rotates in the pulp cavity, thereby removing necrotic tissue, diseased tissue and bacterial infection in the pulp cavity. At the same time, the root canal preparation device generates high-frequency vibration while rotating, which increases the contact area between the preparation device and the inner wall of the pulp cavity and improves the working efficiency of the preparation device. The dynamometer is a device for measuring the power of an object. It calculates the power by measuring the force applied by the object and the speed at which the object moves. Specifically, it is measured based on the relationship between the force applied by the object and the speed at which the object moves.

[0029] In this embodiment, the outer diameter of the buckle portion 21 is smaller than the outer diameter of the connecting portion 22, so that the buckle portion 21 can extend into the root canal preparation machine 30 and buckle therewith, so that the root canal preparation machine 30 can drive the dynamometer fixture 20 to rotate when it rotates; wherein the dynamometer fixture 20 is made of 304 stainless steel, but is not limited thereto, there are three threaded holes 24, and the three threaded holes 24 are arranged on the connecting portion 22 at intervals of 120°, wherein the fixing member 40 can be a screw, which is threadedly connected to the threaded hole 24. It can be understood that the fixing member 40 is tightened in the threaded hole 24 so that the fixing member 40 is against the rotating shaft of the dynamometer 10, and the dynamometer fixture 20 is firmly fixed on the rotating shaft 11, so that the root canal preparation machine 30 can drive the rotating shaft 11 to rotate, and the dynamometer 10 calculates the power value to detect whether the power of the root canal preparation machine 30 meets the standard.

[0030] Working principle: The dynamometer fixture 20 is mounted on the rotating shaft 11 of the dynamometer 10, the fixing part 40 is tightened in the threaded hole 24 to fix the dynamometer fixture 20 on the rotating shaft 11, and then the output end of the root canal preparation machine 30 is buckled with the buckle part 21, so that the root canal preparation machine 30 can drive the dynamometer 10 to operate through the dynamometer fixture 20, and the dynamometer 10 detects whether the power of the root canal preparation machine 30 meets the standard.
