Description

Technical Field

[0001] This invention relates to the field of nut breaking technology, specifically to a multifunctional adaptive anti-loosening nut breaking device. Background Technology

[0002] Nuts can become difficult to loosen due to rust or other reasons after prolonged use, requiring the use of demolition tools to break them down.

[0003] When dealing with rusted or difficult-to-remove nuts in extreme situations, traditional demolition tools are difficult to use and lack effective rust removal and lubrication functions. Currently, the most common solution is to rely on a separate rust removal and lubrication bottle, but this brings new problems: the rust removal and lubrication bottles commonly available on the market are large, meaning that the bottle takes up space when carried separately, is easy to lose, and requires frequent tool switching during operation, making the process cumbersome.

[0004] Furthermore, in extreme working environments such as darkness and high altitudes, the drawbacks of individual bottles are amplified: searching in the dark is difficult, seriously affecting the efficiency of emergency repairs; when working at heights, carrying an extra individual item not only increases the load, but also adds the step of picking up and putting back the item, and the risk of shaking and accidental falling poses a serious safety hazard.

[0005] In summary, a multifunctional adaptive anti-loosening nut breaking device needs to be developed to solve the above problems. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a multifunctional adaptive anti-loosening nut breaking device, comprising: a tool handle, a nut cavity, a screw, a cutting head, and a limiting surface. An auxiliary breaking mechanism is slidably connected to the outer surface of the tool handle. This mechanism, as an optional independent functional mechanism, adopts a lightweight design. Without affecting the structural strength of the main body of the breaking device and its core breaking function, it provides users with a chemical-assisted solution for dealing with extreme corrosion conditions, and integrates portability, operation, and maintenance. Furthermore, the auxiliary breaking mechanism also has the following characteristics: The positioning component includes a positioning slide frame and pull lugs fixed to the two edges of the positioning slide frame. A support component is fixed to the center of the upper surface of the positioning slide frame. The positioning slide frame is made of high-strength engineering plastic, which is lightweight and wear-resistant. It is wrapped around the tool handle, enabling flexible adjustment of the overall position of the auxiliary mechanism. This allows the operator to quickly adjust the chemical spraying component to the optimal working position according to the available space and the position of the nut. The pull lugs, as force-bearing protrusions, facilitate the user's finger application to slide the entire auxiliary mechanism. The design also considers that in extreme cases, the entire auxiliary module can be quickly removed from the demolition tool body by hand for individual maintenance or replacement without affecting the use of the demolition tool body.

[0007] The rust removal component includes a rust removal tube and a split component fixed to the upper surface of the rust removal tube. A liquid inlet assembly is fixed to the upper surface of the rust removal tube. The rust removal tube is a transparent cylindrical container made of chemically resistant material (polycarbonate). It is pre-filled with a special thread-penetrating rust removal lubricant. This agent is stable at room temperature, does not easily solidify or volatilize, and can be stored for a long time while maintaining its efficient penetration and lubrication performance. The transparent tube design allows users to observe the internal liquid level in real time and replenish it in a timely manner. The cleaning component includes a limiting groove formed in the inner wall of the rust removal pipe, and a sealing assembly disposed in the inner wall of the limiting groove. Here, "cleaning component" refers to a structural feature for ease of maintenance, which is associated with the design of the disassembled components and is intended to address the issues of cleaning internal residues or replacing the rust removal fluid after prolonged use.

[0008] Furthermore, the support assembly includes a support frame and a partition groove formed on the upper surface of the support frame for positioning the disassembled components. The support frame serves as the mounting base for the rust-removing components, and the partition groove provides precise guidance and locking space for the rapid installation and locking of the rust-removing components.

[0009] Furthermore, the inner surface of the positioning slide frame is slidably connected to the outer surface of the tool handle. This sliding connection employs a low-friction coefficient fit design, ensuring that the positioning slide frame can move smoothly and stably along the outer surface of the tool handle, and has sufficient static friction to maintain its posture at any position, without the need for additional locking, making operation intuitive and convenient.

[0010] Furthermore, the liquid inlet assembly includes an inlet pipe with a rubber stopper inserted into its inner surface, and a pull rod fixed to the upper surface of the rubber stopper. The inlet pipe serves as a channel for replenishing lubricant, and its orifice design facilitates filling using commonly used nozzles. The rubber stopper and inlet pipe are interference-fitted to ensure the sealing of the liquid reservoir, preventing liquid leakage or the entry of external contaminants. The pull rod is made of flexible rubber, increasing the force-bearing area and providing the user with a clear point of application, allowing the stopper to be easily removed even when wearing gloves or with oily hands.

[0011] Furthermore, a flexible hose is fixed to the outlet end of the rust removal pipe, and a rubber stopper is inserted into the inner wall of the hose. This hose is made of a flexible polymer material (PU tubing of a specific hardness) with a certain shape memory capability and rigidity, rather than a completely soft silicone tube. This allows it to be manually bent and maintained at a set angle to precisely guide the liquid flow, while also resisting unexpected sagging due to gravity, thus adapting to different operating scenarios where the nut is located on the side, top, etc. When not in use, the rubber stopper is tightly inserted into the hose port, forming a second line of defense to effectively prevent the slow seepage of residual liquid.

[0012] Furthermore, a piston is slidably connected to the inner wall of the rust-removing tube. A pressing rod is fixedly connected to one end of the piston, and a pressing plate is fixedly connected to the end of the pressing rod away from the piston. The piston and the inner wall of the rust-removing tube are precisely fitted together, and its sealing ring is made of oil-resistant and corrosion-resistant fluororubber material to ensure effective pressure build-up and no internal leakage during the liquid pushing process. The pressing rod transmits manual operation to the piston, while the pressing plate provides a wide and comfortable pressing area, making each pressing action stable and effortless, and achieving adjustable liquid output.

[0013] Furthermore, the rust-removing tube is detachably installed on the inner surface of the support frame, the piston is located directly below the liquid inlet tube, and the outer surface of the pressing rod is slidably connected to the inner surface of the rust-removing tube. The detachable connection between the rust-removing tube and the support frame is achieved through a snap-fit ​​mechanism, allowing users to quickly remove the entire rust-removing tube for cleaning or replacement when the rust remover runs out or needs to be replaced with a different type, thus improving the tool's sustainable usability and ease of maintenance.

[0014] Furthermore, the splitting component includes a limiting box, the inner surface of which is slidably connected to a limiting baffle, the outer surface of which is provided with an inclined surface, and a spring sheet is fixedly connected to one side of the limiting baffle.

[0015] Furthermore, the limiting box is fixedly connected to the upper surface of the rust-removing pipe, and the end of the spring plate away from the limiting baffle is fixedly connected to the inner wall of the limiting box. The limiting box is a key structure connecting the rust-removing pipe and the support frame. The inclined surface design on the limiting baffle allows the rust-removing pipe to easily slide in and be locked during installation by the guiding action of the inclined surface, achieving quick installation. The spring plate is made of stainless steel with excellent elasticity, providing continuous elastic restoring force to the limiting baffle, ensuring reliable locking after the rust-removing pipe is installed. When disassembly is required, the locking can be released by overcoming the elasticity of the spring plate, embodying the principle of "lock with insertion, unlock with pressing".

[0016] Furthermore, the sealing assembly includes an internal threaded groove formed on the inner surface of the limiting groove. A sealing tube is threadedly connected to the internal threaded groove, and a portion of the inner surface of the sealing tube is slidably connected to the outer surface of the pressing rod. The limiting groove and its internal threaded groove constitute a precise sealing and guiding interface. The threaded sealing tube serves two purposes: firstly, it acts as a precision guide sleeve for the pressing rod's movement, reducing wobbling during pressing and ensuring smooth piston movement; secondly, its tight sliding fit with the pressing rod forms a dynamic seal, which, together with the static seal of the piston, greatly enhances the sealing reliability of the entire liquid-pushing system, preventing liquid leakage from gaps in moving parts. Simultaneously, the threaded connection facilitates the replacement and maintenance of this sealing and guiding component.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention solves the problems of cumbersome tool switching, space occupation, and easy loss caused by the need to carry and retrieve separate rust remover bottles in traditional operations by integrating a sliding auxiliary demolition mechanism into the main body of the demolition device. The design slides the positioning frame to the tool handle, allowing the operator to quickly adjust the rust removal component to the nut working point with one hand, achieving chemical-assisted and mechanical demolition, adapting to the requirements of work efficiency and tool simplicity in extreme spaces such as darkness and heights. The quick-locking anti-slip mechanism, composed of a limit box, spring baffle, and support frame partition groove, solves the problem of accidental sliding or falling off of the auxiliary module due to gravity or vibration in non-horizontal working postures such as high altitudes and tilts. Its lateral locking design provides a rigid constraint perpendicular to the sliding direction, ensuring the absolute stability of the module's position under extreme working conditions and effectively guaranteeing the safety of high-altitude operations. The threaded connection design of the detachable sealing tube and rust removal tube, as well as the integrated constraint structure of the pressing plate, pressing rod, and piston, resolves the contradiction between the need for deep cleaning during system maintenance and the easy scattering and loss of small parts. Unscrewing the sealing tube exposes all the inner walls for thorough cleaning, while key moving parts are naturally restrained, avoiding the risk of cylindrical parts rolling, being lost, or getting dirty when maintaining them in complex field environments such as outdoors or at high altitudes.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] For the first embodiment, please refer to... Figures 1-7 This invention relates to a multifunctional adaptive anti-loosening nut breaking device, comprising: a tool handle 1, a nut cavity 2, a screw 3, a cutting head 4, and a limiting surface 6. An auxiliary breaking mechanism 5 is slidably connected to the outer surface of the tool handle 1. This mechanism, as an optional independent functional mechanism, adopts a lightweight design. Without affecting the structural strength of the main body of the breaking device and its core breaking function, it provides users with a chemical-assisted solution for dealing with extreme corrosion conditions, and achieves integration of portability, operation, and maintenance. Furthermore, the auxiliary breaking mechanism 5 also has the following features: The positioning component 51 includes a positioning slide frame 511 and pull lugs 512 fixed to the two sides of the positioning slide frame 511. A support component is fixed to the center of the upper surface of the positioning slide frame 511. The positioning slide frame 511 is made of high-strength engineering plastic, which is lightweight and wear-resistant. It is wrapped around the tool handle 1, which realizes flexible adjustment of the overall position of the auxiliary mechanism. This allows the operator to quickly adjust the chemical spraying component to the optimal working position according to the site space and the position of the nut. The pull lugs 512 serve as force-bearing protrusions, which facilitate the user's fingers to apply force to slide the entire auxiliary mechanism. Its design also takes into account that in extreme cases, the entire auxiliary module can be quickly removed from the demolition tool body by hand for individual maintenance or replacement without affecting the use of the demolition tool body.

[0022] Rust removal component 52 includes a rust removal tube 521 and a split component 522 fixed to the upper surface of the rust removal tube 521. A liquid inlet assembly is fixed to the upper surface of the rust removal tube 521. The rust removal tube 521 is a transparent cylindrical container made of chemically resistant material (polycarbonate). It is pre-filled with a special thread-penetrating rust removal lubricant. This agent is stable at room temperature, does not easily solidify or volatilize, and can be stored for a long time while maintaining its efficient penetration and lubrication performance. The transparent tube design allows users to observe the internal liquid level in real time and replenish it in a timely manner. The cleaning component 53 includes a limiting groove 531 formed in the inner wall of the rust removal pipe 521, and a sealing assembly disposed in the inner wall of the limiting groove 531. Here, "cleaning component 53" refers to a structural feature for ease of maintenance, which is associated with the design of the disassembled component 522 and is intended to address the issues of cleaning internal residues or replacing the rust removal fluid that may occur after long-term use.

[0023] The support assembly includes a support frame 513 and a partition groove 514 formed on the upper surface of the support frame 513 for positioning the disassembled component 522. The support frame 513 serves as the mounting base for the rust-removing component 52, and the partition groove 514 on it provides precise guidance and locking space for the quick installation and locking of the rust-removing component 52.

[0024] The inner surface of the positioning slide frame 511 is slidably connected to the outer surface of the tool handle 1. This sliding connection adopts a low coefficient of friction design to ensure that the positioning slide frame 511 can move smoothly and stably along the outer surface of the tool handle 1, and has sufficient static friction to maintain its posture at any position without the need for additional locking, making operation intuitive and convenient.

[0025] The liquid inlet assembly includes an inlet pipe 523, with a rubber stopper 524 inserted into its inner surface. A pull rod 525 is fixed to the upper surface of the rubber stopper 524. The inlet pipe 523 serves as a channel for replenishing lubricant, and its orifice design facilitates filling using commonly used nozzles. The rubber stopper 524 and the inlet pipe 523 are interference-fitted to ensure the sealing of the reservoir and prevent liquid leakage or the entry of external contaminants. The pull rod 525 is made of flexible rubber, increasing the force-bearing area and providing a clear point of application for the user, allowing the stopper to be easily removed even when wearing gloves or with oily hands.

[0026] A flexible hose 526 is fixedly connected to the outlet end of the rust removal pipe 521, and a rubber stopper plate 527 is inserted into the inner wall of the hose 526. The hose 526 is made of a flexible polymer material (PU tubing of specific hardness) with a certain shape memory capability and rigidity, rather than a completely soft silicone tube. This allows it to be manually bent and maintain a set angle to precisely guide the liquid flow, while also resisting unexpected sagging due to gravity, thus adapting to different operating scenarios where the nut is located on the side, top, etc. When not in use, the rubber stopper plate 527 is tightly inserted into the port of the hose 526, forming a second line of defense to effectively prevent the slow leakage of residual liquid.

[0027] A piston 528 is slidably connected to the inner wall of the rust removal tube 521. A pressing rod 529 is fixedly connected to one end of the piston 528, and a pressing plate 5210 is fixedly connected to the end of the pressing rod 529 away from the piston 528. The piston 528 fits precisely with the inner wall of the rust removal tube 521, and its sealing ring is made of oil-resistant and corrosion-resistant fluororubber material to ensure effective pressure build-up and no internal leakage during the liquid pushing process. The pressing rod 529 transmits manual operation to the piston 528, while the pressing plate 5210 provides a wide and comfortable pressing area, making each pressing action stable and effortless, and achieving adjustable liquid output.

[0028] The rust removal tube 521 is detachably mounted on the inner surface of the support frame 513. The piston 528 is located on one side directly below the liquid inlet tube 523. The outer surface of the pressing rod 529 is slidably connected to the inner surface of the rust removal tube 521. The detachable connection between the rust removal tube 521 and the support frame 513 is achieved through a snap-fit ​​mechanism, allowing users to quickly remove the entire rust removal tube 521 for cleaning or replacement when the rust remover runs out or when a different type of rust remover needs to be used, thus improving the tool's sustainable usability and ease of maintenance.

[0029] The specific work process is as follows: First, when the operator encounters a nut that is difficult to remove due to severe corrosion, the nut cavity 2 of this device is placed outside the target nut, and the screw 3 is rotated using an external driving tool or wrench to drive the cutter head 4 forward, performing basic mechanical dismantling preparation. During this process, if the maintenance personnel determine that chemical assistance is needed, there is no need to find and retrieve a separate rust remover bottle.

[0030] Next, the operator can hook the pull ring 512 with their fingers and slide the entire auxiliary demolition mechanism 5 along the outer surface of the tool handle 1. The low-friction sliding connection design between the positioning slide frame 511 and the tool handle 1 allows the user to quickly and smoothly adjust the rust removal component 52 at the front end of the mechanism to the optimal working point closest to the nut gap, based on the site layout and the actual position of the nut. The positioning slide frame 511 is held in this position by static friction and the limiting surface 6, without the need for additional locking steps. This sliding adjustment function of the positioning component 51 ensures that chemical assistance can be precisely intervened without interfering with the alignment and clamping of the demolition tool body.

[0031] Next, lubricant is applied. The operator removes the rubber stopper 527 from the end of hose 526 and manually bends and shapes hose 526 according to the orientation of the nut (e.g., side or bottom). This hose 526, made of a shape-memory polymer, maintains a set angle and resists unintended sagging, precisely guiding the outlet to the threaded connection of the nut and bolt. The operator then presses the pressure plate 5210 with their thumb, pushing the piston 528 inside the rust-removing tube 521 via the pressure bar 529. The corrosion-resistant piston 528 ensures effective pressure build-up, squeezing out the pre-stored, dedicated thread-penetrating rust-removing lubricant. The lubricant flows through hose 526, being applied directly to the target gap in controlled droplets. The transparent rust-removing tube 521 allows the operator to monitor the remaining lubricant level and control the number of presses. After application, the rubber stopper 527 is reinserted into hose 526 to prevent leakage, and the hose is left to stand for a moment to allow the lubricant to fully penetrate the rust layer.

[0032] Finally, perform maintenance. When the lubricant inside the rust removal tube 521 is depleted after prolonged use, the operator can pinch the pull rod 525 to pull out the rubber stopper 524 from the inlet tube 523, and add new lubricant to the transparent rust removal tube 521 through the inlet tube 523. After completion, tighten the stopper to seal it. However, if new rust removal lubricant is added directly to an uncleaned rust removal tube 521, the residual old lubricant will mix with the new lubricant. While this operation seems simple, it may introduce new problems: First, when users replenish the rust-removing lubricant, they may use different brands or batches. The chemical composition of these lubricants may vary, and mixing them can lead to unpredictable reactions, causing colloid precipitation or sediment formation. These impurities can easily clog the small hose 526 and its outlet, causing subsequent pressing to fail. Second, the old rust-removing lubricant may have absorbed metal oxide particles or environmental pollutants over time. Mixing it will contaminate the entire can of new fluid, significantly reducing its permeability and lubrication performance, affecting the demolition assistance effect. Third, from a user's psychological and safety perspective, a visible turbid mixture inside the hose can raise doubts about the tool's reliability. In emergency scenarios requiring high reliability, such as in darkness or at high altitudes, this uncertainty is unacceptable. Therefore, to ensure the continued reliability and optimal performance of the chemical assistance function, timely cleaning after the lubricant is depleted, rather than direct mixing and refilling, is a more professional and reliable practice.

[0033] Therefore, it is best to clean the inside after long-term use. The operator can remove the rust removal pipe 521 from the support frame 513 through the partition groove 514 structure on the support frame 513 to facilitate subsequent disassembly and internal cleaning.

[0034] In summary, this embodiment solves the problem of "traditional demolition tools lacking effective rust removal assistance" by integrating a sliding and positioning auxiliary demolition mechanism 5 into a traditional demolition tool. This mechanism, as a dedicated extension module for the demolition tool, features a positioning slide frame 511, pull lug 512, and support frame 513, all specifically designed for the square handle of the demolition tool. These components are not parts that can be arbitrarily attached to other tools and are only applicable to this model of demolition tool. This avoids the problems of space occupation, easy loss, and difficulty in searching in dark environments caused by operators carrying separate rust remover bottles. More importantly, the sliding adjustment and the design of the shape-adjustable hose 526 enable one-handed, rapid, and precise application of rust remover in extreme conditions such as narrow spaces and high altitudes, reducing tool switching steps and the risk of parts falling. It seamlessly integrates chemical assistance with mechanical demolition, forming an integrated demolition process.

[0035] It should be added that the rust removal tube 521 in this device is filled with a thread-penetrating rust-removing lubricant. This preparation is a common standard industrial product on the market, characterized by its strong penetrability and effective lubrication. The directionally bendable hose 526 and pressing parts of this device are designed to precisely apply this preparation and assist in its penetration into the threaded joint surfaces of nuts and bolts, thereby achieving a highly efficient synergy between chemical rust removal and mechanical demolition, solving the problems of cumbersome and ineffective independent operation of rust removers and demolition tools in the prior art.

[0036] For the second embodiment, please refer to... Figures 1-8 Based on Embodiment 1, the split component 522 includes a limiting box 5221, a limiting baffle 5222 is slidably connected to the inner surface of the limiting box 5221, an inclined surface 5223 is provided on the outer surface of the limiting baffle 5222, and a spring sheet 5224 is fixedly connected to one side of the limiting baffle 5222.

[0037] The limiting box 5221 is fixedly connected to the upper surface of the rust-removing pipe 521, and the end of the spring plate 5224 away from the limiting baffle 5222 is fixedly connected to the inner wall of the limiting box 5221. The limiting box 5221 is a key structure connecting the rust-removing pipe 521 and the support frame 513. The inclined surface 5223 on the limiting baffle 5222 allows the rust-removing pipe 521 to slide in and be locked easily during installation by the guiding action of the inclined surface 5223, achieving quick installation. The spring plate 5224 is made of stainless steel with excellent elasticity, providing continuous elastic restoring force to the limiting baffle 5222, ensuring reliable locking of the rust-removing pipe 521 after installation. When disassembly is required, the lock can be released by overcoming the elastic force of the spring plate 5224, embodying the principle of "lock with insertion, unlock with pressing".

[0038] The sealing assembly includes an internal threaded groove 532, which is formed on the inner surface of the limiting groove 531. A sealing tube 533 is threadedly connected to the internal threaded groove 532, and a portion of the inner surface of the sealing tube 533 is slidably connected to the outer surface of the pressing rod 529. The limiting groove 531 and its internal threaded groove 532 constitute a precise sealing and guiding interface. The threaded sealing tube 533 serves as a precision guide sleeve for the movement of the pressing rod 529, reducing wobbling during pressing and ensuring smooth movement of the piston 528. Furthermore, its tight sliding fit with the pressing rod 529 forms a dynamic seal, which, together with the static seal of the piston 528, greatly enhances the sealing reliability of the entire liquid-pushing system, preventing liquid leakage from gaps in moving parts. The threaded connection also facilitates the replacement and maintenance of this sealing and guiding component.

[0039] The specific work process is as follows: Based on all the functions of the first embodiment, this embodiment extends and improves the auxiliary demolition mechanism 5, especially the maintainability and cleanability of the rust removal component 52.

[0040] First, the rust removal pipe 521 is connected to the support frame 513 via a splitting component 522. This splitting component 522 includes a limiting box 5221 fixed to the upper surface of the rust removal pipe 521. A slidable limiting baffle 5222 is provided inside the box. One side of the limiting baffle 5222 is connected to the inner wall of the limiting box 5221 via a spring plate 5224. Figure 6 and Figure 7 As shown, at this time, part of the limiting baffle 5222 is inserted into the inner wall of the limiting box 5221, and part is exposed. The extended end of the limiting baffle 5222 is also designed with a slope 5223.

[0041] During installation, the operator holds the rust removal pipe 521, aligns the upper limit box 5221 with the partition groove 514 on the support frame 513, and pushes it upward along the groove. Initially, the inclined surface 5223 of the limit baffle 5222 contacts the side wall of the partition groove 514. Under the continued pushing force, the inclined surface 5223 generates a guiding force, forcing the limit baffle 5222 to compress the spring plate 5224 and slide and retract into the limit box 5221, allowing the rust removal pipe 521 assembly to move smoothly upward. When the rust removal pipe 521 is fully in place, i.e., when part of the outer surface of both sides of the limit box 5221 is still in contact with the corresponding side wall of the partition groove 514, and the limit baffle 5222 has just moved to a position where it is no longer interfering with the partition groove 514, such as... Figure 4 and Figure 6 As shown in the diagram. At this moment, the elastic restoring force of the spring plate 5224 immediately drives the limiting baffle 5222 to pop outward, so that its end is firmly locked onto the stop surface located behind the top of the partition groove 514 on the support frame 513. This process realizes the locking and installation of the rust removal pipe 521.

[0042] The advantage of this design is that, with traditional vertically inserted modules, when the tool is used at an angle (such as when working at height or applying force from the side), the module may slide down the guide groove due to gravity or vibration. This device, through the lateral locking of the limiting baffle 5222, provides a rigid constraint perpendicular to the sliding direction, eliminating the possibility of the rust removal tube 521 accidentally sliding down the inner surface of the support frame 513. At the same time, the tight fit between the two side walls of the limiting box 5221 and the partition groove 514 restricts the possibility of the rust removal tube 521 swinging left and right or rotating, ensuring its absolute stability under complex working conditions such as tilting and vibration, providing a solid foundation for subsequent precise spot coating.

[0043] Disassembly is equally quick. The operator simply uses their thumb and forefinger to simultaneously press the exposed ends of the limiting baffles 5222 on both sides of the limiting box 5221, overcoming the elasticity of the spring plates 5224, causing the two baffles to retract into the box and disengage from the locking part of the support frame 513. Then, the entire rust removal pipe 521 assembly can be smoothly slid down along the partition groove 514 for disassembly. The entire assembly and disassembly process requires no tools and can be completed with one hand in seconds.

[0044] Secondly, regarding sealing reliability and prevention of parts scattering during maintenance, this embodiment improves the sealing and guiding at the connection between the rust-removing tube 521 and the sealing tube 533. A limiting groove 531 with an internal threaded groove 532 is provided at the top of the rust-removing tube 521. An independent sealing tube 533 is tightly installed in this limiting groove 531 by threaded engagement. The pressing rod 529 penetrates this sealing tube 533, and its outer surface forms a precise sliding pair with the inner wall of the sealing tube 533.

[0045] This structure offers two major advantages: The sealing tube 533 acts as a precision guide sleeve for the pressing rod 529, reducing radial wobble and uneven wear of the pressing rod 529 during reciprocating motion. This makes the movement of the piston 528 smooth, helps control the liquid output, and the good sealing performance prevents rust remover and lubricant from leaking back from the gaps between moving parts, ensuring reliable sealing during long-term use and preventing liquid contamination of tools or users.

[0046] When it is necessary to clean the inside of the rust removal tube 521, the piston 528, and the inner wall of the sealing tube 533, the sealing tube 533 can be unscrewed from the rust removal tube 521. At this time, the pressing plate 5210, the pressing rod 529, and the piston 528 are integrated as a whole. The diameter of the pressing plate 5210 is designed to be larger than the inner diameter of the sealing tube 533, but smaller than the inner diameter of the mounting channel of the support frame 513. This key dimension design means that after the sealing tube 533 is removed, the pressing plate 5210, the pressing rod 529, and the piston 528 will not completely fall out of the sealing tube 533, but will be supported by the opening of the sealing tube 533, meaning that this component cannot be accidentally dropped. This allows for the complete exposure of all surfaces requiring cleaning (the inner wall of the rust removal tube 521, the piston 528, the inner wall of the sealing tube 533, and the pressing rod 529), while naturally constraining all small cylindrical moving parts (the pressing rod 529 and the sealing tube 533) in their associated positions. This solves the problem of parts being disassembled and disordered during maintenance, leading to easy rolling, scattering, and loss. It is especially suitable for rapid maintenance and cleaning in complex on-site environments such as the field and at high altitudes.

[0047] After maintenance, the cleaned parts can be easily assembled in reverse order: first push the pressing rod 529 and the pressing plate 5210 into the initial position of the inner wall of the sealing tube 533, then align the sealing tube 533 and screw it into the limiting groove 531 so that the sealing tube 533 is threadedly connected to the rust removal tube 521, and finally put the entire rust removal tube 521 assembly back into the support frame 513.

[0048] In summary, this embodiment achieves rapid assembly and disassembly of the module through a locking mechanism consisting of the limiting box 5221, spring baffle, and partition groove 514. Its lateral locking mechanism ensures that the module is securely locked even during operations at heights or at inclines, preventing accidental slippage due to gravity or vibration and ensuring operational safety. Secondly, the separable threaded connection between the sealing tube 533 and the rust-removing tube 521 provides a reliable seal while allowing the pressing rod 529, piston 528, and pressing plate 5210 to be constrained as a whole outside the sealing tube 533 during cleaning and maintenance. This avoids the problem of multiple small precision parts being easily lost, rolled, or the piston 528 being placed on the ground and contaminated with dirt after complete disassembly in field or high-altitude environments. This design reduces the number of completely separable parts while ensuring that all inner wall surfaces can be cleaned.
