[0040] To facilitate mechanical adjustment of the number of heating rods 141 in use, the heating rods 141 provided in this invention are arranged in parallel; and a switch 5 is provided between the parallel-arranged heating rods 141 and the power supply; such as Figure 10 The switch 5 includes a square tube 50 and a rod 55 inserted into the square tube 50. Several grooves 51 are provided along the length of each of the two opposite inner walls of the square tube 50. A conductive post A54, movable along the inner wall of the groove 51, is connected to the inner bottom side of the groove 51 via an elastic element 52. An arc surface 54 is provided at the end of the conductive post A54. Several mounting holes 56 are provided along the length of the rod 55. A conductive post B57 is installed in each mounting hole 56. When the two ends of the conductive post B57 abut against the ends of the two conductive posts A54 respectively, the heating rod 141 connected to one end of the conductive post A54 is activated. Furthermore, during use, the number of conductive rods 141 connected is adjusted by controlling the depth of the rod 55 inserted into the square tube 50.

[0041] Example 2; In order to adjust the hot air coverage range according to the number of heating rods 141 in use; the above-mentioned conductive post A54 and conductive post B57 constitute a switch module; when the number of heating rods 141 is 20; wherein the first and second twentieth heating rods 141 are connected to the same switch module, the second and nineteenth heating rods 141 are connected to the same switch module, ..., the ninth and twelfth heating rods 141 are connected to the same switch module, and the tenth and eleventh heating rods 141 are connected to the same switch module.

The cables 4 at both ends of the heat shrink tubing 40 are fixed to the two wire harness fixing structures 34 respectively. At this time, the heat shrink tubing 40 is located between the two wire harness fixing structures 34. When the heat shrink tubing 40 passes through the rectangular channel 11, the hot air sent from the two heating chambers 12 heats the heat shrink tubing 40 to make it shrink.

[0050] To prevent the cable in the fixing mechanism 3 from being excessively droopy, the present invention fixes an L-shaped support rod 32 on the outer wall of the sleeve 30 located between the wire harness fixing structure 34 and the suspension rod 31. During installation, the cable 4 located between the cable reel and the heat shrink tubing 40 is laid on the L-shaped support rod 32.

[0051] Example 5; In addition to using linear conveying equipment such as linear modules and belt conveyors, the present invention can also use a ring conveying mechanism; such as Figure 8-9 The annular conveying mechanism includes a frame 20, driven pulleys 22 and driving pulleys 23 located at both ends of the frame 20, and an annular guide rail 21 mounted on the frame 20.

[0055] In use; after the slider structure 26 moves one, two or three stations; the control motor stops and drives the ring conveyor mechanism to stop; then the loading and unloading operations of cable 4 are carried out at the loading station and the unloading station respectively.

[0056] In the above usage; when the slider structure 26 moves to three stations to stop the machine; that is, it is necessary to install a cable 4 on the slider structure 26 of the three stations at the same time; at this time, when the machine is stopped, keep the rectangular channel 11 free of cable 4; control that after every interval of at least one slider structure 26, install a cable 4 on the three consecutively set slider structures 26.
