[0035] The shape and size of the cross shaft 8 and the cross plastic connecting shaft 9 are matched with each other, the cross shaft 8 is made of metal material, the cross plastic connecting shaft 9 is made of engineering plastic, and the cross shaft 8 and the cross plastic connecting shaft 9 reduce vibration / sound transmission while connecting and transmitting torque;

[0036] Specifically, the cross shaft 8 and the cross plastic connecting shaft 9 are connected with the connecting shaft in the motor, after being connected with the motor, through the driving of the motor, the connection of the connecting shaft in the motor and the cross shaft 8 is utilized to drive the grinding needle 1 connected on the main shaft 3 to rotate, and the grinding is completed; the inner wall of the chuck 2 is used for clamping the grinding needle 1, and the main shaft 3 is connected through the connecting shaft. One end of the connecting shaft is fixed with the chuck body, and the other end is provided with an interface matched with the motor, and the material is alloy steel, so that the coaxiality with the motor is ensured. The grinding needle 1 is a working component for nail polishing; the thickness of the copper ring is 1.5 mm, the outer diameter is 9.8 mm, and the inner diameter is 6 mm; the spring 7 is a spiral spring, the spring elastic coefficient is 25 N / mm, the length is 8 mm, and the outer diameter is 6.5 mm; the surface of the aluminum pipe 6 is subjected to anodic oxidation treatment, the aluminum pipe 6 is a cylindrical structure, the wall thickness of the aluminum pipe 6 is 0.6-0.7 mm, and the length of the aluminum pipe 6 is 13 mm; the O-ring 10 is made of rubber material, the diameter of the main shaft 3 is 9.7 mm, and the length is 32.5 mm; the inner diameter of the first bearing 5 and the second bearing 14 is 8 mm, and the outer diameter is 12 mm;

[0037] Please refer to Figure 1 、 Figure 4 and Figure 5 , the utility model provides a kind of nail polishing machine chuck of embodiment provided by the utility model: the spring 7 is fixedly installed in the outer wall bottom of the second copper ring 15, the cross shaft 8 is installed in the outer wall bottom of spring 7, and the cross shaft 8 is connected with the one end of chuck 2 and the inner of main shaft 3, and the grinding needle 1 in chuck is clamped and connected in the inner of main shaft 3;

[0038] The cross shaft 8 is fixedly installed with small spring 11 in the outer wall bottom, the cross plastic connecting shaft 9 is installed around the outer wall of cross shaft 8, and the O-ring 10 is fixedly installed in the outer wall bottom of cross plastic connecting shaft 9; spring 7 and small spring 11 are spring steel, and spring 7 and small spring 11 are positioned by buffer / return force for chuck 2, cross shaft 8 is used for connecting and transmitting torque, cross plastic connecting shaft 9 is used for transmission, insulation and buffering, and O-ring 10 is used for reducing shaking and impact;

[0039] The first wave coil gasket 12 and the second wave coil gasket 13 are made of metal / non-metal elastic material, and the first wave coil gasket 12 and the second wave coil gasket 13 reduce impact and wear between components;

[0040] Specifically, after the motor is started, power is transmitted to the main shaft 3 through the connecting shaft. Since the main shaft 3 is connected to the chuck 2, power is further transmitted to the chuck 2, so that the chuck 2 drives the grinding needle 1 to rotate and realizes the nail polishing work; when the grinding needle 1 is impacted / vibrated during work, the spring 7 and the small spring 11 play a buffering role. The spring 7 is compressed under pressure and absorbs impact energy, and at the same time, the small spring 11 will also deform accordingly, thereby reducing the impact on the chuck 2 and the main shaft 3; after the impact, the spring 7 and the small spring 11 use their own elastic restoring force to make the chuck 2 return to the normal position, ensuring the working stability of the grinding needle 1; the first wave coil gasket 12 and the second wave coil gasket 13 can buffer the pressure change and impact between the main shaft 3 and other components during the rotation of the main shaft 3, reduce the wear between components, and improve the service life of the entire chuck structure; the first copper ring 4 and the second copper ring 15 not only have the function of conducting electricity, which is used to transmit current in the motor / other related circuits, to ensure the normal operation of some electrical functions of the nail polisher, but also have the function of sealing, which prevents dust, impurities, etc. from entering the connection part of the main shaft 3 and other components, protects the internal parts from the influence of the external environment, and ensures the working accuracy and reliability of the chuck.

[0041] The working principle is that the chuck 2 holds the grinding needle 1 on the inner wall, and the chuck contains multiple clamping jaws which are evenly distributed around the grinding needle 1. When the grinding needle 1 is inserted into the chuck, the clamping jaws shrink towards the center under the action of the spring, tightly holding the handle of the grinding needle 1, thereby realizing reliable clamping of the grinding needle 1. This clamping method can not only ensure that the grinding needle 1 does not loosen and fall off during high-speed rotation, but also facilitates the replacement of the grinding needle 1. The main shaft 3, as the core transmission component of the entire chuck structure, is supported and rotated with high precision by the first bearing 5 and the second bearing 14, and is electrically conducted and sealed by the first copper ring 4 and the second copper ring 15. The spring 7 and the small spring 11 play an important buffering and adjusting role during work, and the elastic restoring force of the spring can also fine-tune the position of the chuck 2. The cross shaft 8 can uniformly transmit the elastic force of the spring to related components while transmitting torque, making the entire chuck structure more balanced under stress. When the motor vibrates, the cross plastic connecting shaft 9 can first absorb part of the vibration energy, and then the spring can buffer and adjust the remaining energy, thereby minimizing the interference of vibration on the work of the grinding needle 1. The O-ring 10 seals to prevent dust from entering.

[0042] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
