[0022] Preferably, the blowing ring 201 is coaxially arranged with the extruder head 101 , and the blowing holes 202 are arranged in a circular shape on the blowing ring 201 .

[0023] Among them, the blowing holes 202 arranged in a circular shape can quickly cool the extruder head 101 and the extruded cable 360°, increase the contact area between the extruder head 101 and the cable and the air, enable the extruder head 101 and the cable to quickly dissipate heat, and achieve the purpose of rapid cooling.

[0024] Preferably, a fixed half ring 206 is provided on both sides of the extruder head 101, and connecting blocks 207 are fixedly connected to the upper and lower sides of the fixed half ring 206. The connecting blocks 207 are bolted together, and a thermistor 208 is installed inside the side of the fixed half ring 206 adjacent to the extruder head 101.

[0025] The fixed half ring 206 can be installed on the extruder head 101 through bolts between the connecting blocks 207 , so that the thermistor 208 inside the fixed half ring 206 is fully fitted with the extruder head 101 .
