[0025] The back of the cover 2 is fixed with a sleeve 7, and the shaft 5 is located in the sleeve 7, and the shaft 5 is movably connected with the sleeve 7, the shaft 5 is located at the center of the plurality of gear parts and connected with the gear, and is limited by the front of the casing 1, and after the cover 2 and the front of the casing 1 are installed, the sleeve 7 on the cover 2 is aligned with the shaft 5, so that the shaft 5 can rotate in the sleeve and be limited and installed.

[0026] The inside of the cover 2 is provided with a locking mechanism 6, which includes a docking rod 61 embedded in the docking port at the center of the cover 2, and the docking rod 61 is fixed with the front of the casing 1, and the surface of the docking rod 61 is respectively connected with a fixed joint 63 and a movable joint 64, and the inside of the cover 2 is provided with a sliding groove 66, and the sliding groove 66 is respectively installed with a contraction rod 67 and a locking head 65, and the locking head 65 is trapezoidal. The traditional cover 2 usually uses screws and other components to install and fix with the casing 1, which is difficult to separate the cover 2 from the casing 1 when replacing the gear in the later period, and even needs to use special tools to remove, which is more troublesome. Therefore, the traditional screw fixing method is replaced by the locking mechanism 6 which can be quickly disassembled. The docking rod 61 at the center of the front of the casing 1 is inserted after being aligned with the casing 1. At this time, because the cover 2 is pushed, the locking head 65 can be displaced and contracted when encountering the fixed joint 63 at the first end of the docking rod 61, until the first click sound is heard, indicating that the cover 2 and the casing 1 are installed.

[0027] The locking head 65 is fixed to one end of the retractable rod 67, and both the locking head 65 and the retractable rod 67 are located inside the slide groove 66. A limiting plate 69 is fixed inside the slide groove 66, and the retractable rod 67 is fitted into the central through hole of the limiting plate 69. A spring 68 connects the limiting plate 69 and the locking head 65. It should be noted that the locking head 65 is trapezoidal, and the surface of the fixed joint 63 is also inclined. As the inclined surface of the locking head 65 moves with the cover 2, it gradually contacts the surface of the fixed joint 63. Under the interaction of the inclined surfaces, the locking head 65 can retract and move. The locking head 65 is directly connected and fixed to the hand lever. Both are located within the slide groove 66 of the cover 2. The slide groove 66 is divided into a rectangular section and a cylindrical section. Part of the slide groove 66 is used for the sliding of the locking head 65, while the cylindrical slide groove 66 is used for the sliding of the retractable rod 67. The top radius of the retractable rod 67 is larger than the through hole of the limiting plate 69, so that the retractable rod 67 will not disengage from the slide groove 66. A spring 68 is included between the locking head 65 and the limiting plate 69. Therefore, when the inclined surface of the locking head 65 contacts the surface of the fixed joint 63, the spring 68 is compressed, and the locking head 65 and the retractable rod 67 are retracted into the slide groove 66. Only after the locking head 65 moves to the position between the fixed joint 63 and the movable joint 64 will the locking head 65 have space to pop out. At this time, when the cover 2 is manually pulled out, the locking head 65 directly abuts against the back of the fixed joint 63. Without the inclined surface, it cannot be pulled out to achieve locking.

[0028] The fixed joint 63 is fixed to the head end of the docking rod 61, and the movable joint 64 is sleeved on the surface of the docking rod 61 and movably connected to the surface of the docking rod 61. A magnetic ring 62 is fixed on the surface of the docking rod 61, and the movable joint 64 and the magnetic ring 62 are magnetically attracted to each other. The movable joint 64 can slide on the surface of the docking rod 61. Under normal circumstances, the movable joint 64 and the magnetic ring 62 on the surface of the docking rod 61 are magnetically attracted to each other and will not change their position without the action of external force. When it is necessary to separate the cover 2 from the housing 1 to repair or replace the gear set on the front of the housing 1, the cover 2 needs to be pushed again. When locked, the cover 2 and the housing 1 are connected by the sleeve 7 and the shaft 5. There is a certain gap between them, so the cover 2 can be pushed again. Both ends of the movable joint 64 have parts that cooperate with the inclined surface of the locking head 65. When the cover 2 is pushed again, the locking head 65 first contacts the first end of the movable joint 64 and retracts until it moves to the end position, then pulls the cover 2 back, driving the movable joint 64 to move until it moves to fit against the fixed joint 63. At this time, the locking head 65 is in a retracted state, and the user can quickly pull the cover 2 out and separate it from the housing 1. At this time, the magnetic ring 62 plays a role. After the next installation, the movable joint 64 can be manually moved to the fixed position to ensure that the movable joint 64 will not be affected and move during installation. Working principle: When started, motor 12 drives output gear 43 to rotate, which drives transmission gear 41 to move through transmission pinion 42. The large gear meshes with half gear 32 on the double wing 3, causing the integrated flap 31 and half gear 32 to swing up and down synchronously, achieving a biomimetic flight effect. The cover 2 is fixed to the shell 1 by quick locking mechanism 6. During installation, push the cover 2 to retract the locking head 65 along the inclined surface of the fixed joint 63. After sliding into the slot between the fixed joint 63 and the movable joint 64, the spring 68 pops out the locking head 65 to complete the locking. When maintenance is required, push the cover 2 again, and the locking head 65 squeezes the inclined surface of the movable joint 64 to retract. Pull the cover 2 back to drive the movable joint 64 to disengage from the magnetic ring 62 limit, and the cover 2 can be separated to expose the internal gear set. The whole process does not require tools and can be quickly completed for disassembly and assembly.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
