Description

Technical Field

[0001] This utility model relates to the field of unlocking and locking screws, specifically a general-purpose unlocking and locking tool. Background Technology

[0002] Currently, there are many supporting tools for live-fire exercises, both air-to-air and air-to-ground, which are inconvenient and inefficient for actual support. Each system is self-contained, with complicated supporting tools that are difficult to support and lack universality.

[0003] We need to design a universal tool that integrates the unlocking and locking tools for air-to-air launchers, air-to-ground launchers, and missile racks into one tool that is easy to use, store, carry, and provide field support. It also needs to be modularly replaceable. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a universal locking and unlocking tool to address the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A universal locking and unlocking tool includes a main handle, a first screwdriver rod, and a second screwdriver rod. The first screwdriver rod has a first hexagonal screwdriver and a short-legged screwdriver at its two ends, and the second screwdriver rod has a second hexagonal screwdriver and a third hexagonal screwdriver at its two ends. The main handle has a cubic and a cylindrical end, respectively. A first square through-hole is formed on the end face of the cubic end of the main handle, which is used to match an external torque wrench. The four sides of the cubic end of the main handle have first, second, third, and second hexagonal through-holes, respectively, which are used to match and engage with the first, second, third, and short-legged screwdrivers. The dimensions of the first, second, and third hexagonal through-holes are all different. A rectangular notch is formed on the outer side of the cylindrical end face of the main handle, which is used as a wrench.

[0007] Furthermore, the radii of the first hexagonal screwdriver, the second hexagonal screwdriver, and the third hexagonal screwdriver increase sequentially.

[0008] Furthermore, the main body cross-section of the first screwdriver rod is square, and the main body cross-section of the second screwdriver rod is circular. The cylindrical end of the main handle has two storage slots, a first storage slot and a second storage slot, respectively for placing the first screwdriver rod and the second screwdriver rod, along the axis of the main handle. The first storage slot is connected to the rectangular notch.

[0009] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0010] This utility model integrates unlocking and locking tools for air-to-air launchers, air-to-ground launchers, and missile racks into one unit. This integrated design avoids the cumbersome use of multiple different tools, significantly improving the convenience and efficiency of operators in actual support work. The tool's main handle has multiple through holes of different shapes and sizes to connect with different screws on the first and second screw rods. This design allows for modularization of each screw, enabling flexible combination and replacement according to actual needs. When a screw is damaged or needs upgrading, only the corresponding screw module needs to be replaced, without replacing the entire tool, reducing maintenance costs and improving the tool's sustainable usability. Two storage slots are provided along the axial direction at the cylindrical end of the main handle, for holding the first and second screw rods respectively, with the storage slot for the first screw rod connected to a rectangular notch. This storage design allows the screwdriver rod to be neatly stored inside the main handle when not in use, which not only reduces the space occupied by the tool and makes it convenient to carry and store, but also prevents the screwdriver rod from being lost or damaged, thus improving the overall portability and durability of the tool.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description
