A return spring 13 is sleeved on the surface of the plug plate 5, and the top and bottom ends of the return spring 13 are respectively connected to the side where the placement frame 6 and the cross plate 4 are close to each other. The placement frame 6 is arc-shaped, and the arc inner wall of the placement frame 6 is hinged with two symmetrically distributed clamping plates 7, and the surface of the clamping plate 7 is installed with an anti-slip rubber pad. Both sides of the first base 1 are threadedly installed with fastening screws 8, and the ends of the fastening screws 8 extend to the inside of the movable groove 12.

[0038] Working principle: When the device is in use, first adjust the overall length of the first base 1 and the second base 2 according to the factory-specified size of the fan blades. When adjusting, first turn the fastening screw 8 to make the second base 2 slide inside the movable groove 12 of the first base 1, so that the distance between the two baffles 3 on the first base 1 and the second base 2 is slightly larger than the length of the fan blades. Then pull the placement frame 6 at the top of the second base 2 to drive the cross plate 4, and the cross plate 4 then drives the slider 14 to slide inside the slide groove 9, so that the placement frame 6 at the top of the second base 2 moves approximately to the middle position of the overall length of the first base 1 and the second base 2, and then place the fan blades to be transported on the entire device. On the body, the end or tail of the fan blade is placed inside the placement rack 6 at the top of the first base 1, and the middle position of the fan blade is located inside the placement rack 6 at the top of the second base 2. At this time, due to the weight of the fan blade itself, the fan blade will press the placement rack 6 on the second base 2 downward, so that the placement rack 6 squeezes the reset spring 13, and at the same time the placement rack 6 will push the plug plate 5 to be inserted into the appropriate plug hole 11, thereby fixing the position of the placement rack 6 at the top of the second base 2 and supporting the middle position of the fan blade, and then push the second base 2 so that the baffle 3 at the top of the second base 2 contacts the end or tail of the fan blade, and then tighten the fixing screws 8.

[0039] The device can effectively fix fan blades of different lengths, and can adjust the position of the placement frame on the second base according to the length of the fan blades, so that it can effectively support the middle part of the fan blades and prevent the fan blades from shaking and deforming during transportation, and is suitable for promotion.
