When the line clamp is applied to the power cable, the ice layer on the power cable needs to be removed, otherwise the line clamp is not easy to penetrate the power cable when clamping the power cable, and in addition, the ice layer will form a gap between the line clamp and the power cable after melting, causing the line clamp to shake and cause the safety of the power cable. Therefore, if there is ice layer on the power cable when the line clamp is applied in winter, the ice layer on the power cable needs to be removed. The current method is to knock the power cable with an insulation rod to knock off the ice layer on the power cable. This method is labor-intensive and uncomfortable when knocking. SUMMARY

[0027] Through the above setting, the application is labor-saving and comfortable when deicing. Specifically, when deicing, the lower end of the hand-held rod body 11 is held, and then the air outlet head 12 is held high and close to the power cable 21, so that the first clamping groove 1213 and the second clamping groove 12241 are located above the power cable 21, and then the air outlet head 12 is moved downward through the rod body 11, so that the power cable 21 is embedded in the first clamping groove 1213 and the second clamping groove 12241, at this time the air outlet head 12 is placed on the power cable 21, and the hand can be removed from the rod body 11, thereby achieving the effect of saving labor, see Figure 6 and Figure 7 At this time, the power cable 21 is located at the bottom of the first clamping groove 1213 and the second clamping groove 12241, the axes of the inner plate 1222, the outer plate 1221, the guide plate 1211, and the power cable 21 coincide, and the rotating device 13 drives the inner sleeve to rotate one hundred and eighty degrees around the axis of the power cable 21, at this time the water outlet 12242 is rotated to below the power cable 21, so as to discharge the water formed after the ice layer melts, and the opening of the second clamping groove 12241 is upward and forms a via hole with the first clamping groove 1213, see Figure 8 and Figure 9 and Figure 10 , thereby preventing the application from falling off the power cable 21, in addition, at this time the first air outlet 12111 is located above the power cable 21, when the nitrogen cylinder 14 outputs nitrogen to the cavity 1225 and the first air outlet 12111, the nitrogen is output from the first air outlet 12111 and the second air outlet 12221, the nitrogen output from the first air outlet 12111 passes between the sealing plates 1223 and blows downward to the upper side of the power cable 21, and the nitrogen output from the second air outlet 12221 blows to the lower side and both sides of the power cable 21, in summary, the nitrogen is basically uniformly blown to the outer periphery of the power cable 21, so that the ice layer on the outer periphery of the power cable 21 can be subjected to nitrogen, in addition, when the nitrogen output from the nitrogen cylinder 14 passes through the heating device 15, the heating device 15 heats the nitrogen, so that the temperature of the nitrogen increases, thereby accelerating the melting speed of the ice layer. After the ice layer melts, the water in liquid state is formed, and the water falls downward to the inner plate 1222 and then is discharged through the water outlet 12242, thereby preventing the water from entering the inner sleeve through the second air outlet 12221. The application uses hot nitrogen to melt the ice layer, which is labor-saving, and the nitrogen also has the effect of flame retardant, so that the deicing process is very safe, and it is not necessary to knock the power cable 21 as in the traditional method, and the comfort is greatly improved.
