The electromagnet 11 generates magnetism when energized and is magnetically connected to the top rod 8, so that the top rod 8 is fixed. A threaded turning handle 13 is threadedly connected to the top surface of the clamping seat 3. One end of the threaded turning handle 13 is rotatably connected to the top surface of the active seat 5. A threaded hole for the threaded connection of the threaded turning handle 13 is provided on the clamping seat 3. Bottom plates 14 are fixedly connected to the bottom surfaces of the side plates 1.

The electromagnet 11 is electrically connected to the mobile power source 15 and the switch 16 through a wire.

[0022] By the piston block 9 squeezing the spring 10 and moving in the cavity 6, the extending length of the top rod 8 is changed, so that the ends of the top rods are all abutted against the surface of the wind power generation blade. And the top rod 8 is magnetically fixed by the electromagnet 11, so that the curved wind power generation blade is stably clamped by the top rod 8.

[0023] A rubber sleeve 12 is fixedly installed at the other end of the top rod 8.

[0024] Through the arrangement of the rubber sleeve 12, soft contact is provided, so as to avoid damaging the surface of the blade when the top rod 8 clamps the wind turbine blade.

At this time, the wind turbine blade is pressed on the top rod 8 on the fixed seat 4, and the top rod 8 is squeezed and shrinks. At the same time, the threaded handle 13 is rotated to drive the movable seat 5 to fall until the top rod 8 on the movable seat 5 is against the wind turbine blade and squeezes and shrinks until all the top rods 8 are in contact with the separated power generation blade. At this time, the electromagnet 11 magnetically attracts the top rod 8 to form a fixing effect, so that the wind turbine blade is clamped and fixed. At this time, the separated power generation blade can be tested, and the clamping seat 3 can be flipped over by cooperating with the rotating seat 2.

[0031] During the clamping process of the push rod 8, the rubber sleeve 12 is provided to provide soft contact, thereby preventing the push rod 8 from causing damage to the surface of the wind turbine blade when clamped on the blade.
