[0015] Compared with the related art, the lead clamp for mounting the photovoltaic power equipment has the following beneficial effects:

[0016] The combination of V-shaped and arc-shaped clamps allows for excellent adaptation to cables of different specifications. The V-shaped clamps provide initial cable fixation, while the arc-shaped clamps further increase the contact area between the cable and the clamp, improving the clamping effect. Meanwhile, the spring design inside the arc-shaped clamps allows the clamps to adapt to cables of different diameters, eliminating the need for customization for specific cable specifications.

[0017] By turning the universal crank, the drive assembly can be activated, causing the two V-shaped clamps to move closer or further apart, thus flexibly adjusting the clamping force. This design ensures that the cable will not wear or loosen due to excessively tight or loose clamping during long-term use.

[0018] The rotating component design allows the fixed frame to rotate relative to the connecting cylinder, thereby quickly adjusting the angle of the clamp. The operator only needs to pull out the universal crank from the rotating rod one and insert it into the square rod end of the rotating rod two, and then rotate the universal crank to adjust the angle of the clamp. This design simplifies the adjustment steps and improves work efficiency.

[0019] The rotating assembly uses a worm gear and worm shaft combination design with a self-locking function. Once the angle of the clamp is adjusted, the friction between the worm gear and worm shaft will prevent the clamp from rotating, thus ensuring the stability of the clamp. This design ensures that the clamp will not change its angle due to external forces during installation, guaranteeing the safety and stability of the cable. Attached Figure Description
