[0015] Beneficial effects Compared with the prior art, the present invention provides a power driver adapted to different lamps, which has the following beneficial effects: 1. A power driver adapted to different lamps is provided with a fixed card block and a clamping block, and the fixed card blocks on both sides of the power driver body are placed between the two clamping blocks. The clamping knob is rotated to rotate the bidirectional screw, thereby pushing the moving blocks on both sides to move toward the middle of the sliding groove. At the same time, the rack drives the gear to rotate, and then the gear and the rack ensure that the two moving blocks move synchronously toward the middle of the sliding groove, so that the two clamping blocks clamp the power driver body from both sides of the fixed card block, thereby facilitating quick disassembly and assembly of the power driver body, improving practicality, and facilitating replacement of power driver bodies of different specifications adapted to different lamps.

[0016] 2. A power driver adapted to different lamps is provided with a positioning protrusion and a positioning groove. When two clamping blocks fix the power driver body from both sides of the fixed clamping block, the positioning protrusion is clamped with the inside of the positioning groove to prevent the power driver body from being offset during installation.

[0017] 3. A power driver adapted to different lamps is provided with an auxiliary heat dissipation component. When the power driver body is installed, the heat conduction plate is lifted so that the connecting pull rod drives the sliding block to retract toward the middle, causing the spring to be squeezed and contracted. After the power driver body is fixed by the clamping block and the fixed clamping block, the heat conduction plate is released. Under the action of the spring, the sliding block slides toward both ends along the guide slide rod, so that the heat conduction plate is pressed against the top of the power driver body. The heat generated by the power driver body is conducted to the heat dissipation fins through the heat conduction plate to perform auxiliary heat dissipation, thereby improving the heat dissipation efficiency of the power driver body.
