The arc of the pressing plate, the supporting plate and the clamping plate of the original patent device is fixed, when fixing the windmill blade, it is impossible to completely match the blade arc, and the smaller the circumference of the wind power blade is, the smaller the contact area of the blade is, and the lower the fixing strength is, so that the blade may shake when moving the device, therefore it is not suitable for all specifications of blades. 2. And each support top is equipped with an adjusting rod, and the adjusting rod is connected with the pressing plate, representing that the pressing plate will also rotate with the rotation of the adjusting rod, therefore the problem that when the pressing plate is parallel with the wind power blade, the both ends of the arc surface have already resisted the blade and cannot continue to descend, and the problem that when the pressing plate descends to the both ends of the inner arc surface below the highest point of the blade, but has not been matched and continues to descend, causing the problem of unable to rotate.
