A slider 4 is slidably connected inside each of the four sliding grooves 3. A fixing plate 5 is fixed on one side of the slider 4. An adjusting screw 6 penetrates through the fixing plate 5. A hand-twisting head 7 is fixed at the rear end of the adjusting screw 6. A limiting block 8 is fixed at the front end of the adjusting screw 6. A clamping plate 9 is connected to one side of the limiting block 8. Through the sliding grooves 3 opened on the device base plate 1, the slider 4 can slide, so as to adjust the position of the fixing plate 5, and thus the positions between the four clamping plates 9 can be adjusted, so as to facilitate the clamping and fixing of components of different sizes.

[0023] As a further implementation of the above technical solution: A protective rubber pad 10 is adhered to the side wall of the clamping plate 9. A fixed bearing 11 sleeved on the outer surface of the adjusting screw 6 is embedded in the clamping plate 9. By manually twisting the hand-twisting head 7, the adjusting screw 6 rotates, driving the clamping plate 9 to approach the component to clamp and fix the component. Through the provided limiting block 8, the situation that the clamping plate 9 falls off can be avoided. The fixed bearing 11 in the clamping plate 9 can ensure the normal rotation of the adjusting screw 6.

[0024] As a further implementation of the above technical solution: An adjusting plate 12 is arranged on one side of the device base plate 1. A lead screw 13 is fixed on the side wall of the adjusting plate 12. The lead screw 13 penetrates through the inside of the device base plate 1. Through the provided adjusting plate 12, the component is placed on the adjusting plate 12, which is convenient for further fixing the component.

[0025] Specifically, when using this fixing device for testing sub-components of wind turbine blades, first place the device base plate 1 in a suitable position and fix the device base plate 1 by tightening the fixing bolts 2. When in use, place the component to be tested on the adjusting plate 12. Through the sliding grooves 3 opened on the device base plate 1, the slider 4 can slide, so as to adjust the position of the fixing plate 5, and thus the positions between the four clamping plates 9 can be adjusted, so as to facilitate the clamping and fixing of components of different sizes. After the adjustment is completed, by manually twisting the hand-twisting head 7, the adjusting screw 6 rotates, driving the clamping plate 9 to approach the component to clamp and fix the component. And through the provided limiting block 8, the situation that the clamping plate 9 falls off can be avoided. The fixed bearing 11 in the clamping plate 9 can ensure the normal rotation of the adjusting screw 6. And the provided protective rubber pad 10 can avoid damage to the component during clamping, improving the practicability.

[0026] As a further implementation of the above technical solution: A threaded pipe 14 is threadedly connected to the end of the lead screw 13.

By turning the threaded pipe 14, the adjusting plate 12 can be driven to move, which is convenient for further fixation.

[0027] As a further implementation of the above technical solution: Connecting plates 16 are fixed to both ends of the mounting plate 15. The ends of the connecting plates 16 are fixedly connected to the device substrate 1. By means of the connecting plates 16 provided on the mounting plate 15, the stability of the threaded pipe 14 can be ensured, enabling the device to stably fix the components and reducing the occurrence of detachment.

[0028] As a further implementation of the above technical solution: Two guide rods 17 are symmetrically fixed to the side wall of the adjusting plate 12. Both of the two guide rods 17 penetrate through the inside of the device substrate 1. The guide rods 17 provided on the adjusting plate 12 can play a guiding role.

[0029] As a further implementation of the above technical solution: The adjusting screw 6 is threadedly connected to the fixing plate 5. The clamping plate 9 is rotatably connected to the adjusting screw 6 through a fixed bearing 11. Since the lead screw 13 and the threaded pipe 14 are threadedly connected, the lead screw 13 can move, thereby driving the adjusting plate 12 to move and tightly fixing the components.

[0030] During specific implementation, by turning the threaded pipe 14, since the lead screw 13 and the threaded pipe 14 are threadedly connected, the lead screw 13 can move, thereby driving the adjusting plate 12 to move and further tightly fixing the components. Moreover, the guide rods 17 provided on the adjusting plate 12 can play a guiding role. By means of the connecting plates 16 provided on the mounting plate 15, the stability of the threaded pipe 14 can be ensured, enabling the device to stably fix the components and reducing the occurrence of detachment.
