Nickel-plated copper sheet with external heat dissipation active adjusting assembly

The utility model discloses a nickel-plated copper sheet with an external heat dissipation active adjusting assembly, and belongs to the technical field of nickel-plated copper sheets. The problems that in the prior art, a nickel sheet is poor in adjusting effect and poor in active heat dissipation capacity, and the working efficiency still cannot be guaranteed are solved. According to the nickel-plated copper sheet with the external heat dissipation active adjusting assembly, a transmission sleeve penetrates through the interior of a nickel-plated copper sheet body, a limiting bearing is installed at one end of the transmission sleeve, the limiting bearing is connected with a fixing plate in a welded mode, and the other end of the transmission sleeve is connected with a positioning ring through a shaft sleeve; and a spring rod slides in the transmission sleeve, a rotary knob is installed at one end of the spring rod, installation plates are welded to the two sides of the outer portion of the positioning ring
