[0023] When the clamp is in use, the corresponding multiple moving blocks 3 are inserted into the T-shaped slide groove 2 according to the number of turbines to be clamped. When the moving block 3 is inserted into the T-shaped slide groove 2, the bolt 15 on the blocking block 13 is loosened, the blocking block 13 is lifted, the spring 14 is compressed, and the moving block 3 is pushed along the T-shaped slide groove 2. When the moving block 3 moves to the specified position, the blocking block 13 is lowered, and the spring 14 pushes the blocking block 13 to rotate. The blocking block 13 is clamped to the blocking groove 11, and the bolt 15 on the blocking block 13 is rotated so that the bolt 15 contacts the blocking rack 10, and the moving block 3 is fixed.

In order to solve the above problem, in this embodiment, a plurality of leakage holes 16 are opened at the bottom end of the T-shaped slide groove 2, and the leakage holes 16 pass through the base 1.

[0025] It was found in actual use that when the turbine is ground, the moving block 3 will shake under the action of force.

The limit blocks 17 are fixed to the base 1 by bolts 15. The two limit blocks 17 are movably connected with a limit rod 18, and the limit rod 18 passes through the moving block 3.

[0026] It was found in actual use that when the upper mounting seat 8 and the upper connecting seat 7 rotate, the friction force has a serious impact on the rotation due to the large contact surface. In order to solve the above problem, in this embodiment, a plurality of spherical grooves 19 are provided on the top of the upper mounting seat 8 and the side wall located inside the upper connecting seat 7. A ball 20 is rotatably connected in the spherical groove 19, and the ball 20 is in contact with the inner wall of the upper connecting seat 7.

[0027] It was found during actual use that when the clamping block 9 was fixed on the upper mounting seat 8 and the lower mounting seat 5, due to the need to rotate, the clamping block 9 may be rotationally misaligned with the upper mounting seat 8 or the lower mounting seat 5, and the clamping block 9 needs to be replaced when clamping different turbines, which is not easy to disassemble and install. In order to solve the above problem, in this embodiment, a plurality of plug blocks 21 are fixed on the ends of the upper mounting seat 8 and the lower mounting seat 5 that are close to each other, and a slot 22 adapted to the plug block 21 is opened on the clamping block 9, and the clamping block 9 and the upper mounting seat 8 and the lower mounting seat 5 are all fixed by bolts 15.
