The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] For the embodiments, please refer to Figures 1-3 , this utility model provides a technical solution:

[0024] A detachable aero-engine blade, comprising a blade body 1 and a connecting seat 2. A bottom post 3 is provided at the bottom of the blade body 1. An insertion plate 4 is provided at the bottom of the bottom post 3. Convex blocks 5 are provided on the left and right sides of the insertion plate 4. A limit insertion post 6 is provided at the top of the convex block 5. A groove 7 is formed in the middle of the top of the connecting seat 2. A spring 8 is provided inside the groove 7. A lifting top plate 9 is provided on the upper side of the spring 8. Slots 10 are formed on the top surface of the connecting seat 2 and on the left and right sides of the groove 7. Limit insertion holes 11 are formed on the top surface of the connecting seat 2 and on the front and rear sides of the groove 7.

[0025] In this embodiment, the tangent cross-section of the groove 7 is designed in an "inverted T-shaped" structure. The slot 10 is connected to the groove 7 in a mutually penetrating manner. The connection structure between the insertion plate 4 and the groove 7 is a sliding plug-in connection, and the insertion plate 4 can rotate inside. The connection structure between the convex block 5 and the slot 10 is a sliding plug-in connection. The connection mode between the lifting top plate 9 and the groove 7 is a sliding connection. The connection structure between the limit insertion post 6 and the limit insertion hole 11 is a sliding plug-in connection. By providing the bottom post 3, the insertion plate 4, the convex block 5, the limit insertion post 6, the groove 7, the spring 8, the lifting top plate 9, the slot 10, and the limit insertion hole 11, the connection and separation of the blade body 1 and the connecting seat 2 are facilitated, so that the overall installation and disassembly of the blade body 1 can be facilitated.

[0026] The working process of the present utility model is as follows: When installing the blade main body 1, first align the convex block 5 with the slot 10 and insert it into the groove 7. At this time, the lifting top plate 9 will press down on the spring 8. Then rotate the blade main body 1. At this time, the insertion plate 4, the convex block 5, and the limit insertion post 6 will also rotate together. When the limit insertion post 6 reaches the position of the limit insertion hole 11, release the blade main body 1. At this time, the spring 8 will rebound and push up the lifting top plate 9. Then the limit insertion post 6 will be inserted into the limit insertion hole 11, and at this time, the installation of the blade main body 1 is completed. When disassembling the blade main body 1, press down the blade main body 1 to pull out the limit insertion post 6 from the limit insertion hole 11. Then rotate the blade main body 1 to turn the convex block 5 to the position of the slot 10. Then pull out the insertion plate 4 from the groove 7 to complete the disassembly. Through the setting of the bottom post 3, the insertion plate 4, the convex block 5, the limit insertion post 6, the groove 7, the spring 8, the lifting top plate 9, the slot 10, and the limit insertion hole 11, the connection and separation of the blade main body 1 and the connecting seat 2 are facilitated, so that the overall installation and disassembly of the blade main body 1 can be conveniently carried out.

[0027] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
