A protective frame 18 is installed on the side wall of the bottom of the resistor box body 1, and the heat dissipation fins 17 are located inside the protective frame 18;

[0020] Rotating the stud 4 drives the resistor box body 1 to move upward through cooperation with the U-shaped adjusting plate 5, which can adjust the distance between the N-shaped cross beam 2 and the resistor box body 1, facilitating adjustment according to the installation position and improving the convenience during use.
