Wind energy is an available energy provided to humans by the action of air flow, and belongs to a renewable energy source. The kinetic energy of the air flow is called wind energy. The higher the air flow velocity, the greater the kinetic energy. One can use windmills to convert the kinetic energy of wind into a rotating motion to propel a generator to generate electricity by transmitting the rotational power of a rotor to the generator through a drive shaft. The cost of using wind to generate electricity has been reduced significantly, even if it is free of other external costs, and the cost of using wind power at many suitable sites has been lower than that of using a fuel-fired internal combustion engine. As the world is developing carbon neutralization and carbon peaking, clean energy is becoming a unified direction of global development, which makes wind power generation as one of clean energy also grow and starts to develop rapidly worldwide.

Along with the great development of clean energy in China, the wind power industry rapidly develops, megawatt levels of wind power blades are larger and larger, the length of the wind power blades is from original twenty-three meters to one hundred meters at present, and therefore the cost is high and the operation procedure is complicated when the blade mould is manufactured.

For manufacturers of large modular moulds, in particular wind blade moulds, it has been a challenge to clamp the two halves of the large mould together, and various manual clamping devices have been tried, for example: c-clips, toggle clamps and bolts are used to simply assemble the two halves together.
