The number of fixing positions can be adjusted according to the number of cables. The connecting rod pulls up the pressure block, and the cable passes through the through hole. When the connecting rod is released, the compression spring applies a downward pushing force to the limiting block, causing the pressure block to fall and make close contact with the cable, clamping and fixing the cable passing through the through hole, thus achieving cable fixation.

[0015] 2. The device of this utility model increases the area of ​​the through hole connected to the outside by setting heat dissipation holes, and releases the heat inside the through hole more quickly by means of heat dissipation holes, so as to avoid heat accumulation at the cable fixing part.
