Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Embodiment:

[0028] The utility model provides a fixed tool for folding wing test, its characterized in being: including fixed mounting base 1, fixed clamping plate 7, mounting frame 6, adjusting screw rod 4, movable top block 3 and locking piece 8, one side of mounting frame 6 is hinged with fixed mounting base 1, and the other side is connected with fixed mounting base 1 through locking piece 8, movable top block 3 is movably connected in the inside of mounting frame 6, adjusting screw rod 4 is rotatably connected with movable top block 3 and is threadedly connected with mounting frame 6, locking piece 8 includes plug rod 11, installation box 16, lock head 13, movable rod 14, compression spring 15 and pull ring 17, installation box 16 is fixedly connected on the top of plug rod 11, movable rod 14 is movably connected with installation box 16, compression spring 15 is arranged in installation box 16, and the both ends of compression spring 15 are connected with movable rod 14 and installation box 16, lock head 13 is fixedly connected with movable rod 14, and pull ring 17 is movably connected with installation box 16 and is fixedly connected with movable rod 14, first insertion hole is arranged on mounting frame 6, second insertion hole is arranged on fixed mounting base 1, and plug rod 11 is inserted into first insertion hole and second insertion hole, lock head 13 is matched with lock port 12 on mounting frame 6.

[0029] Specifically, in use, rotating adjusting screw rod 4, adjusting screw rod 4 drives movable top block 3 to move axially, and the wing handle of folding wing is clamped between movable top block 3 and fixed mounting base 1 through movable top block 3. When needing to replace folding wing, pull ring 17 is pulled, movable rod 14 is moved, lock head 13 is driven by movable rod 14 to disengage from lock port 12, then plug rod 11 is pulled out, mounting frame 6 is opened by rotating mounting frame 6 to replace folding wing. After replacing folding wing, mounting frame 6 is closed by rotating mounting frame 6. Pull ring 17 is pulled, plug rod 11 is inserted into first insertion hole and second insertion hole, lock head 13 is aligned with lock port 12, pull ring 17 is loosened, movable rod 14 is reset by compression spring 15, lock head 13 is driven by movable rod 14 to enter into lock port 12, so that the positioning of plug rod 11 is realized. Through the design, different specifications of folding wing can be quickly installed and positioned, and the same specification of folding wing can be quickly replaced, and the test efficiency is effectively improved.

[0030] In a preferred embodiment, the fixed mounting base 1 is provided with a fixed clamping plate 7, and the movable top block 3 is provided with a movable clamping plate 2. Further optimization is that the fixed clamping plate 7 is provided with a notch with a tooth-shaped structure, and the movable clamping plate 2 is provided with a notch with a tooth-shaped structure. When the wing handle of the folding wing is clamped between the movable top block 3 and the fixed mounting base 1 by adjusting the screw rod 4 to drive the movable top block 3 to move axially, the fixed clamping plate 7 and the movable clamping plate 2 cooperate with each other to clamp and fix the wing handle from opposite sides. The notch with a tooth-shaped structure can increase the friction between the clamping plate and the wing handle, prevent the wing handle from loosening or shifting when subjected to external force, and make the fixing of the folding wing more stable and reliable. Since the shapes and sizes of the wing handles of folding wings of different specifications may differ, the notch with a tooth-shaped structure has a certain adaptability. Regardless of whether the wing handle is circular, square or irregular, the tooth-shaped notch can be in contact with the wing handle at different points and better wrap the wing handle, thereby effectively clamping wing handles of various shapes.

[0031] In a preferred embodiment, the fixed mounting base 1 is provided with at least two fixed clamping plates 7. Folding wings of different specifications have wing handles that differ greatly in shape and thickness. The multiple fixed clamping plates 7 can be flexibly adjusted according to the actual shape and size of the wing handle to better fit the wing handle profile.

[0032] In a preferred embodiment, the mounting bracket 6 is fixedly connected with a guide strip 10, and the movable top block 3 is provided with guide grooves 9 on both sides, which cooperate with the guide strip 10. When the movable top block 3 moves axially by rotating the adjusting screw rod 4, the cooperation between the guide strip 10 and the guide grooves 9 can guide the movement of the movable top block 3. The movable top block 3 can only move linearly in the direction defined by the guide strip 10, avoiding deviation or skew during movement, thereby ensuring that the movable top block 3 can accurately move towards or away from the fixed mounting base 1, making the clamping operation of the wing handle of the folding wing more stable and helping to better fix the folding wing.

[0033] In a preferred embodiment, the mounting bracket 6 has a U-shaped structure. The open design of the U-shaped structure makes it more convenient to install and disassemble the folding wing. The operator can easily place the wing handle of the folding wing in the appropriate position through the opening, or easily take it out when it needs to be replaced. The operation space is relatively open, improving the efficiency of the process of installing and replacing the folding wing, and meeting the requirement of operational convenience when the folding wing is frequently replaced during actual testing.

[0034] In a preferred embodiment, the mounting frame 6 is provided with two layers, the two layers of mounting frame 6 are fixed to each other, and the mounting frame 6 at the bottom is connected with the fixed mounting seat 1. Different specifications of folding wings differ in size, shape, weight and the like, and the two layers of mounting frame 6 structure can provide more space layout and mounting points, and the two layers of mounting frame 6 can facilitate the installation of folding wings of different specifications.

[0035] In a preferred embodiment, one side of the adjusting screw 4 is provided with a rotating handle 5. The rotating handle 5 increases the distance between the force application point and the rotation center, and according to the lever principle, more labor can be saved during rotation, and the operator can easily rotate the adjusting screw 4 without exerting great force.

[0036] In a preferred embodiment, the cross section of the lock head 13 is triangular, and the lock head 13 is matched with the lock opening 12. Specifically, the hypotenuse of the triangle faces downward. Through this design, when the plug rod 11 is inserted, the bottom surface of the lock head 13 is in contact with the mounting frame 6, the movable rod 14 is moved by the lock head 13 and the compression spring 15 is compressed, and after the lock head 13 is aligned with the lock opening 12, the lock head 13 automatically enters the lock opening 12, which effectively improves the convenience.

[0037] In a preferred embodiment, the plug rod 11 is fixedly connected with a limiting ring 18. When the plug rod 11 is inserted into the first insertion hole of the mounting frame 6 and the second insertion hole of the fixed mounting seat 1, the limiting ring 18 can play a blocking role to prevent the plug rod 11 from being inserted too deeply, and ensure that the depth of the plug rod 11 inserted each time is consistent. In this way, the lock head 13 and the lock opening 12 can be accurately aligned, so that the lock head 13 can smoothly enter the lock opening 12 and realize reliable locking function, avoiding the situation that the plug rod 11 is inserted too deeply or too shallowly, so that the lock head 13 cannot be normally locked, or unnecessary extrusion and damage to the lock opening 12, the lock head 13 and other related parts, thereby maintaining the stability of the whole tool structure and the normal working state of the locking piece 8.
