The workpiece, such as a metal rope, is described below as a description of the operation of the metal rope, but is not limited thereto. In addition, the working portion 4 further includes at least one elastic member that is elastically opposed between the upper and lower working members 41 and 42 so that the upper and lower working members 41 and 42 have a tendency to move away from each other. The existence of the void can be maintained.

Since the conventional heating device generates a lot of heat during heating and heat conduction to the working portion, the heat dissipating device provided by the present invention can blow the excess heat or discharge through the openings through the opening, which is worth a It is mentioned that since the hot air will rise, the heat dissipating device is disposed on the top of the casing, thereby discharging the hot air relatively completely, and further, the heat dissipating device is located between the working portion and the heating device. Thereby, the heat generated when the working portion and the heating device are thermally insulated from each other can be more directly discharged. Moreover, since the housing has a plurality of holes, when the fan rotates to discharge heat, the holes can also bring outside air of a lower temperature into the interior of the casing, thereby promoting convection and further improving the heat dissipation effect.

In addition, the heat dissipating device can also help the housing to cool down, so that the user does not feel high temperature and feel uncomfortable during use, and the heat dissipating device and the control portion are located at opposite ends of the housing. The hot air emitted by the heat sink is not discharged toward the control unit, so that the user is not burnt by the hot air that is discharged during use, and the safety of use is high.

It is to be noted that the fan of the heat dissipating device faces the second surface, and the angle between the line connecting the first end and the second end and the first surface is greater than the first end and the An acute angle between the line connecting the second end and the second surface, the second surface is substantially oriented toward the second end, so that the hot air generated by the working portion and the heating device is far away from the first Dissipate, and make it The working part at one end is not easy to overheat, so that the heat dissipation efficiency is optimized.
