A taper hole 4 is recessed at the end of the rotating mandrel 3. The taper hole 4 has a broach and a member 5. And at least - a knife handle 6 that is movably secured within the tapered bore 4. There is also a broach shaft 7 which can be combined with the broach assembly 5 and a taper section 8 which can be attached to the scale, and the _ _ _ _ _ _ _ _. The rotating mandrel 3 is coupled to the motor at the other end to drive the rotating mandrel 3 and the tool holder 6 to perform the cutting operation, etc., because the blade member 6 can be replaced with the tool at the speed to meet the processing requirements. The processing spindle group is widely used in various automatic processing machines. However, in general, such processing is performed by simply using the tool holder 6 itself to have a tool hardness higher than that of the workpiece to perform the cutting η. - However, if the hardness is too high, it will easily lead to the wear and tear of the knife handle 6 I. And such as glass, high hardness and easy to crack material, it is easier to produce cracks in the processing. Therefore, a conventional technique disclosed in the "Ultrasonic Processing Machine" of the Republic of China Patent No. 072149 is equipped with a machining head (knife handle) attached to the tip end of the spindle, and the machining head has an ultrasonic wave in the machining head. The ultrasonic vibrator for vibration is machined by the high-frequency vibration of the tool. In addition to greatly reducing the wear of the tool during high-hardness machining, it can prevent the fragile workpiece from being damaged. However, the technology disclosed is that the electrical rotary joint is arranged at the spindle seat of the outer circumference of the processing, and the electric rotary joint is used to introduce the power into the ultrasonic vibrator in the processing head. In addition to affecting the tool change action of the guard head, since the electric rotary joint is exposed outside the spindle seat, the right user is more likely to be accidentally damaged by accidental control. Another kind of conventional technology, such as the towel of the Republic of China, is specifically called M4_3G "Electromagnetic Conduction Device of Ultrasonic Spindle" - an electrical conduction device in the ultrasonic domain. The power supply connector is provided at each of the jaws of the broaching device of the broaching device, and the yoke base and one of the 7 yokes of the yoke are provided with a power supply lead group for connecting to the power supply at the other end of the main shaft. The electric power can be transmitted to the ultrasonic (four) device in the tool holder. This way, the electric conduction device is set inside the main pumping, although the problem of affecting the tool change and the collision is avoided. However, the general spindle group will utilize the tool change. Knife (4) Move the claw seat to push the top and hit the broach shaft to facilitate the exit of the knife handle, and the input power supply connector is _ _ _ _. Moreover, the power connector and the power wire are the general spindle group cutting The position of the liquid central water outlet circuit will cause the problem that the spindle unit cannot be installed with the central water outlet loop, and it lacks practicality. In addition, in order to accurately control the wear or change of the tool during the machining process, the working status can be monitored immediately according to the disclosure of A61. The spindle mechanism of the machine tool is attached to the tool holder. The P detection device is used to measure various tool operating parameters during the machining process, and the M424210 is transmitted from the wireless transmission module in the internal detection device to the external information device to accurately and immediately feedback the working state of the machining tool. However, if an internal detecting device with a detecting and wireless transmitting function is provided for each of the blade members, in addition to causing a substantial increase in manufacturing cost, since the main shaft tool and the machine are all made of metal, it is easy to generate a wireless signal shielding effect. Therefore, there is a need for an electrically conductive device that is inexpensive and has an electrical signal transmission effect.
