By rotating the first seat body 11 and the second seat body 12, the first clamping component 21 and the second clamping component 22 are driven to rotate, so as to clamp and release the blade. Optionally, the end of the first seat body 11 and the second seat body 12 which is detachably connected can be locked or unlocked by the locking component.

[0050] Optionally, the third direction Z intersects with the first direction X and the second direction Y, and can be perpendicular to each other. When the blade is clamped, the third direction Z can be the chord direction of the blade.

[0051] In some optional embodiments, the blade holder provided by one embodiment of the present application, the first clamping component 21 comprises a first clamping unit 21a, and at least one first clamping unit 21a has the freedom of movement and rotation relative to the first base body 11.

Since the first driving part 211 drives the first clamping body 212 to move relative to the first seat body 11, it is beneficial to adjust the clamping force of the first clamping body 212 on the blade. In addition, the first clamping body 212 is rotationally connected to the first driving part 211, so that when the blade is clamped and fixed, the first clamping body 212 can be adjusted relative to the first seat body 11 and the first driving part 211 to better fit the profile of the blade and increase the contact area. Then, the first clamping body 212 is driven to move by the first driving part 211 to clamp and fix the blade, which can ensure the clamping and fixing of the blade and the reliability of the blade transportation.

[0059] In some optional embodiments, the first driving part 211 includes a first telescopic cylinder 2111 connected between the first seat body 11 and the first clamping body 212.

[0069] The first driving parts 211 arranged in pairs of the first clamping unit 21a can be rotatably connected with the first clamping body 212 through the same rotating shaft.

[0070] The blade holder provided by the embodiment of the present application can ensure the stability of the driving of the first clamping body 212 and the reliability of the blade transportation by arranging the first driving parts 211 included in the first clamping unit 21a in pairs and symmetrically distributing the first driving parts 211 on the two sides of the first seat body 11, and rotatably connecting the first driving parts 211 arranged in pairs with the first clamping body 212.

[0071] In some optional embodiments, the blade holder provided by one of the embodiments of the present application has the second clamping component 22, which comprises a second driving part 221 and a second clamping body 222, the second clamping body 222 is rotationally connected with the second driving part 221 and is configured to clamp the blade, and the second driving part 221 is arranged on the second seat body 12 and is configured to drive the second clamping body 222 to move relative to the second seat body 12.

[0072] The second driving part 221 comprises but is not limited to a telescopic cylinder, a screw rod or the like structure. The second clamping body 222 and the second driving part 221 can be connected in a manner of shaft hinging, spherical hinging, universal joint connection or the like.

[0073] It can be understood that the above-mentioned embodiments of the present application are all exemplified by taking the first driving part 211 comprising the first telescopic cylinder 2111 as an example, and are not limited thereto. In some embodiments, the first driving part 211 can also comprise a linear motor, a rotary motor and a cooperation structure of a scissor fork, or any structure capable of realizing length change and directly or indirectly driving the first clamping body 212 to move relative to the first seat body 11.

[0074] The blade holder provided by one of the embodiments of the present application has the second clamping assembly 20 in the above-mentioned structure, which can utilize the second clamping body 222 to contact the blade and clamp and fix the blade together with the first clamping assembly 20. Since the second driving part 221 drives the second clamping body 222 to move relative to the second seat body 12, it is beneficial to adjust the clamping force of the second clamping body 222 on the blade. In addition, the second clamping body 222 is rotationally connected with the second driving part 221, so that during clamping of the blade, the angle of the second clamping body 222 relative to the second seat body 12 and the second driving part 221 can be adjusted to better fit the profile of the blade and increase the contact area. Then, the second clamping body 222 is driven to move by the second driving part 221 to clamp and fix the blade, which can ensure the clamping and fixing effect on the blade and ensure the reliability of the blade transportation.

[0075] In some optional embodiments, the blade holder provided by one of the embodiments of the present application has the second driving part 221, which comprises at least one of a second telescopic cylinder and a drive screw.

[0076] The second driving part 221 can comprise a second telescopic cylinder, which can be connected between the second seat body 12 and the second clamping body 222. The second telescopic cylinder can be fixedly connected with the second seat body 12 and rotatably connected with the second clamping body 222. The extension and retraction of the second telescopic cylinder can drive the second clamping body 222 to move relative to the second seat body 12. The rotatable connection between the second telescopic cylinder and the second seat body 12 can drive the second clamping body 222 to rotate relative to the second seat body 12, thereby satisfying the movement and rotation freedom of the second clamping body 222 relative to the second seat body 12, better fitting the profile of the blade, and locking and fixing the blade through the extension of the second telescopic cylinder, thereby ensuring the stability of clamping the blade.

[0077] Of course, in some embodiments, the second driving part 221 can also comprise a driving screw, which is rotatably connected with the second clamping body 222. The driving screw and the second seat body 12 can be gap-fitted with each other. The relative position between the driving screw and the second seat body 12 after adjustment can be fixed by a pair of locking nuts arranged on the driving screw. For example, the driving screw and the second seat body 12 can be clamped and fixed by two locking nuts, thereby shortening the relative position between the driving screw and the second seat body 12. When it is necessary to adjust the relative position between the driving screw and the second seat body 12 to drive the second clamping body 222 to move, the two locking nuts can be unlocked, so that the driving screw can move relative to the second seat body 12 and drive the second clamping body 222 to move to a suitable position. Then, the locking nuts are tightened again to lock the position of the adjusted driving screw, thereby satisfying the driving requirement of the movement and rotation freedom of the second clamping body 222.

[0078] In some optional embodiments, the blade holder further comprises a leading edge fitting part 30 and a trailing edge fitting part 40. The leading edge fitting part 30 is rotatably connected with the base body 10 and is configured to fit with the leading edge of the blade. The trailing edge fitting part 40 is fixedly connected with the base body 10 and is configured to fit with the trailing edge of the blade. Through the above arrangement, the stability of the blade during transportation can be further improved.

[0079] In another aspect, an embodiment of the present application also provides a blade transportation system, which comprises a transportation device and the blade holder described above, and the blade holder is arranged on the transportation device.

[0080] The blade holder can be directly or indirectly connected with the transportation device. The blade is clamped and fixed by the blade holder and transported to a predetermined position by the transportation device.
