There is a receiving cavity at the top of the placing column. There are several arc-shaped corners in the receiving cavity, forming a windmill shape.
[0007] Preferably, the height of the receiving cavity is lower than the height of the fin, and the height of the receiving cavity is higher than half of the height of the fin.
[0008] Preferably, the fixing ring is made of nylon plastic, and its inner diameter is larger than the maximum outer diameter after the fin is retracted.
[0009] Preferably, the fin includes a cylinder body. There are several groups of positioning blocks equidistantly distributed on the outer wall of the cylinder body. There is a main shaft between each group of positioning blocks. Tail fin pieces are hinged at both ends of the main shaft. There is a spring coil in the middle of the main shaft, and its working end is connected to the middle of the tail fin piece.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] 1. The folding tail rocket folding and fixing tooling described in the utility model can fold the tail pieces by placing the tail pieces in the accommodating cavity and then slowly rotating the tail pieces. After all the tail pieces are folded, the fixing ring can be taken out to cover them. All the tail pieces can be folded at the same time, which greatly reduces the operation time and difficulty.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figures 1-4 The utility model provides the following technical solutions: a folding tail rocket folding and fixing tool, including a folding seat 1, a accommodating cavity 2 is provided on the top of the folding seat 1, a plurality of arc-shaped corners are provided in the accommodating cavity 2, a tail 3 is inserted in the accommodating cavity 2, and a fixing ring 4 is provided on the tail 3.
[0019] Specifically, the folding seat 1 includes a base 6, a placement column 7 is provided in the middle, the base 6 is provided with a plurality of mounting holes 5 around the placement column 7, a receiving cavity 2 is provided on the top of the placement column 7, and a plurality of arc corners are provided in the receiving cavity 2 to form a windmill shape. The design of the entire folding seat 1 is relatively simple, and the material selection is reasonable, which not only ensures strength and durability, but also controls costs.
[0020] Specifically, the height of the accommodation cavity 2 is lower than that of the fin 3, and the height of the accommodation cavity 2 is higher than half of the height of the fin 3. This ensures that during the folding process of the fin blade 10, most of the side wall of the accommodation cavity 2 is contacted by the blade body, making the force evenly distributed and preventing the blade body from deforming.
[0021] Specifically, the fixing ring 4 is made of nylon plastic, and its inner diameter is larger than the maximum outer diameter of the fin 3 after folding. The nylon plastic material of the fixing ring 4 is not only lightweight but also has a certain elasticity, facilitating the tightening of the fin 3. At the same time, the wear resistance and corrosion resistance of nylon plastic also ensure the long-term use effect of the fixing ring 4.
[0022] Specifically, the fin 3 includes a cylinder body 9. A number of groups of positioning blocks 12 are equidistantly distributed on the outer wall of the cylinder body 9. A main shaft 8 is provided between each group of positioning blocks 12. The two ends of the main shaft 8 are hinged with a fin blade 10. A spring ring 11 is provided in the middle of the main shaft 8, and its working end is connected to the middle of the fin blade 10.
[0023] The working principle and usage process of the present utility model: For the folding fin rocket bomb folding and fixing tooling described in the present utility model, first, the base 6 is fixed on the workbench by the cooperation of external screws and the mounting holes 5. Then, the fin 3 is placed in the accommodation cavity 2. Then, the fin 2 is slowly rotated, and the fin blade 10 is resisted by the arc angle, causing it to fold towards the outer wall of the cylinder body 9. After all are folded, the fixing ring 4 is taken to cover all the fin blades 10. Then, the fin 3 is taken out, and the above operations are repeated until all the fins 2 are folded.
[0024] 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.
