A clamping block 10 is provided on the surface of the leg column 4. The through groove 7 penetrates the bottom surface of the cylinder column 2, and the through groove 7 communicates with the chute 5 and the clamping groove 6. The upper middle part of the leg column 4 is arranged in the through groove 7. The width of the clamping block 10 is adapted to the chute 5 and the clamping groove 6, and the clamping block 10 is arranged in the clamping groove 6; when producing the training platform for the electric drive independent pitch of the wind turbine generator set, the clamping tool is required to clamp the platform to ensure the stability during the production of the training platform. When adjusting the height of the clamping platform 1, the length of the leg column 4 in the cylinder column 2 is adjusted by pulling the leg column 4. After adjusting it to the appropriate length, the clamping block 10 is moved to the corresponding clamping groove 6 by rotating the leg column 4 to limit it. The adjustment of the length of the leg column 4 realizes the adjustment of the height of the clamping platform 1, so that it can effectively adapt to production operators of different heights for use, reduce the fatigue of the personnel, and improve the production efficiency.

[0025] Embodiment 2: On the basis of Embodiment 1, in order to improve the stability of the leg column 4, a first internal thread 8 is provided on the surface of the through groove 7, a first external thread 9 is provided on the surface of the leg column 4, a handle 11, a second internal thread 12 and a limiting ring plate 13 are provided on the surface of the limiting cylinder 3, and a second external thread 14 is provided on the surface of the limiting ring plate 13.
