Abstract
Description
Technical Field
[0001] This utility model relates to the field of tool pliers technology, and in particular to a tool pliers for disassembling and assembling the hammer spring of a 92 series pistol. Background Technology
[0002] The hammer spring of the Type 92 series pistol is a double-strand helical spring made of high-quality spring steel, possessing high fatigue resistance and stability. Its main function is to provide the return force for the hammer, ensuring reliable operation of the firing mechanism. The spring has a compact design, is compatible with the Type 92 pistol series, and exhibits outstanding durability, capable of withstanding frequent firing cycles. It undergoes precision winding and heat treatment to ensure sustained spring force and stable performance in environments ranging from -40℃ to 50℃. It is a key component ensuring the reliability of continuous firing of the pistol, and pliers are required for disassembly and assembly.
[0003] The 92 series pistol hammer spring disassembly and assembly pliers are typically made of high-strength alloy steel. The structure includes a pliers head, spring retainer, and handle. The pliers head is designed in a U-shape or hook shape to precisely engage specific parts of the hammer spring top pin; the handle has a non-slip texture for easy application of force. In use, the pliers head engages with the fixed end of the hammer spring top pin, using leverage to compress or release the spring, causing it to disengage or return to its original position. This tool avoids the risks of manual operation, improves disassembly and assembly efficiency, reduces damage to the spring, and ensures safe and reliable maintenance.
[0004] The core drawback of traditional tools for disassembling and assembling the hammer spring of the Type 92 pistol is that they are laborious to operate and prone to damaging parts. Because the hammer spring (especially the double-strand helical spring) has a strong elastic force, manual tools rely on levers for hard pressure, which easily leads to slippage or loss of control, causing the spring to deform or even break off. Simultaneously, the direct friction between the metal jaws and the spring's top pin can scratch the surface with prolonged use, affecting the spring's force stability. Therefore, a new type of pliers for disassembling and assembling the hammer spring of the Type 92 series pistols is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a pair of pliers for disassembling and assembling the hammer spring of the 92 series pistol, aiming to improve the problem of easy slippage or slippage in the prior art, which leads to deformation or even breakage of the spring.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A pair of pliers for disassembling and assembling the hammer spring of a 92 series pistol includes two handles that are rotatably connected. One end of each handle is fixedly connected to a jaw, and one side of one jaw is fixedly connected to an extension block. A locking block is fixedly connected to the outside of the extension block.
[0008] As a further description of the above technical solution:
[0009] Another clamping groove is provided on one side of the jaw;
[0010] As a further description of the above technical solution:
[0011] The two handles have grooves on their adjacent sides, and springs are fixedly connected to the inner walls of the grooves.
[0012] This utility model has the following beneficial effects:
[0013] In this invention, the extension block extends the clamping groove and engages with the locking block, and with the auxiliary positioning of the locking block, the problems of slippage and loss of hand in traditional disassembly and assembly are effectively solved, avoiding the risk of the hammer spring flying out. The high-strength jaws and anti-slip texture reduce hard friction between metals, prevent scratches on the spring surface, and ensure the stability of the spring force. The spring-assisted rebound structure improves the smoothness of operation and reduces fatigue damage. The overall design ensures the safety of disassembly and assembly while significantly extending the service life of the hammer spring and tools, taking into account both efficiency and reliability.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figure 1 This utility model provides an embodiment of a pair of pliers for disassembling and assembling the hammer spring of a 92 series pistol. The pliers include two handles 1, which provide uniform grip force through a symmetrical design, making it easy to operate with one or two hands. The two handles 1 are rotatably connected and use a hinge structure to realize the opening and closing action, ensuring operational flexibility and stability. One end of each handle 1 is fixedly connected to a jaw 2, which is made of high-strength steel and can withstand the elastic force of the hammer spring without deformation. One side of one of the jaws 2 is fixedly connected to an extension block 3, which increases the length of the jaw 2, making it easier to operate in the narrow space inside the pistol.
[0019] The extension block 3 is externally fixedly connected to a locking block 4 to ensure precise locking and prevent slippage. Another jaw 2 has a clamping groove 5 on one side. The inner wall of the clamping groove 5 has anti-slip texture to enhance the fixing effect on the hammer spring and prevent loosening during operation. The two handles 1 have grooves on their adjacent sides. The inner wall of the grooves is fixedly connected to a spring 6. The spring 6 provides a rebound force so that the pliers automatically remain open when not in use, which is convenient for quick and repeated use.
[0020] Working principle: When in use, the operator grips both handles 1, and the lever force generated by the rotation of the hinge structure closes the jaws 2. The extension block 3 engages with the groove of the hammer spring to ensure a stable bite. Meanwhile, the clamping groove 5 of the other jaw 2 firmly fixes the other end of the hammer spring with anti-slip texture to prevent slippage. The spring 6 automatically rebounds when the handle 1 is released, allowing the jaws 2 to return to the open state for continuous operation. Throughout the process, the jaws 2, made of high-strength steel, can effectively resist the elastic force of the hammer spring, ensuring a safe and efficient disassembly and assembly process. This design not only ensures the accuracy of operation but also improves the durability and convenience of the tool.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
