Description

Technical Field

[0001] This invention relates to the field of firearms maintenance technology, specifically a multifunctional firearms cleaning and maintenance device. Background Technology

[0002] Firearm maintenance consists of two parts: post-firing and post-firing maintenance. During use, especially after firing, gunpowder and other contaminants accumulate inside the firearm, such as in the chamber, firing pin, and barrel. If these residues are not cleaned regularly, gunpowder buildup can occur, affecting the firearm's performance and potentially causing malfunctions such as barrel explosions or jamming, posing a serious threat to the user's safety. Cleaning and maintaining firearms ensures optimal accuracy and consistency during use, guarantees the proper functioning of all components, and extends the firearm's lifespan.

[0003] When cleaning and maintaining firearms, they are usually placed on a firearms maintenance rack for support and clamping. The firearms are then disassembled and cleaned using tools such as brushes, tissue paper, and cleaning agents. However, when applying cleaning agent to tissue paper, there may be instances where too much or too little cleaning agent is used. Excessive use of cleaning agent can corrode the surface of the firearm, attract dust from the air, forming more stubborn dirt, or mix with gun oil to form a sticky substance, affecting the use of the firearm. Conversely, insufficient cleaning agent will not effectively clean the firearm, making it inconvenient for maintenance personnel to perform the cleaning and maintenance. Therefore, we propose a multi-functional firearms cleaning and maintenance device. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional firearm cleaning and maintenance device to solve the problems mentioned in the background art, where applying cleaning agent to cotton paper for firearm cleaning and maintenance can result in either too much or too little cleaning agent. Excessive use of cleaning agent can corrode the surface of the firearm and attract dust from the air, forming more stubborn dirt, or it can mix with gun oil to form a sticky substance, affecting the use of the firearm. On the other hand, insufficient cleaning agent cannot effectively clean the firearm, making it inconvenient for maintenance personnel to clean and maintain the firearm.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figures 1 to 12 The present invention provides a technical solution: a multi-functional firearm cleaning and maintenance device, comprising: a bracket 11, a tool box 12 placed on the upper side of the bracket 11, and screw members 13 symmetrically threaded on both sides of the bracket 11; It also includes: support component 2, which is set on the upper side of bracket 11. The support component 2 adjusts the support and clamping position and angle of the firearm according to different firearms. Cleaning component 3 is installed on the upper side of bracket 11. Cleaning component 3 automatically adjusts the corresponding discharge amount of cleaning agent according to the amount of dirt wiped off by the cotton paper during cleaning. Adjustment component 4 is located on one side of bracket 11. Adjustment component 4 automatically limits the amount of cleaning agent discharged at the current gun length according to the relative length of the support component 2 when the gun is clamped. Adjustment component 5 is located on one side of adjustment component 4. Adjustment component 5 adjusts the discharge amount of cleaning agent based on the placement angle of the support component 2 when cleaning different parts of the receiver and barrel, on the basis of the discharge amount of cleaning agent limited by adjustment component 4.

[0020] When cleaning and maintaining firearms, the four screws 13 can be rotated to stably support the bracket 11. The toolbox 12 can hold tools such as brushes for cleaning firearms. The support assembly 2 provides stable support and clamping for the firearm, allowing for disassembly and cleaning with tools such as brushes and tissue paper. The support assembly 2 also facilitates multi-angle adjustments to the firearm without removing it from the support, making it convenient for maintenance personnel. This allows for easier handling of different parts of the firearm. The cleaning component 3 allows for cleaning and maintenance, improving usability. When cleaning firearms with a tissue paper dipped in cleaning agent, the amount of cleaning agent dispensed each time is automatically adjusted based on the amount of dirt removed. This adaptive adjustment of cleaning agent usage effectively reduces the risk of overuse, preventing potential damage to the firearm and avoiding waste, while ensuring effective cleaning. The adjustment component 4 allows for adaptive limitation of the current firearm length based on its type (long or short). The initial cleaning agent usage is automatically limited by the cleaning component 3. For rifles, a relatively larger initial cleaning agent usage is used to accommodate the greater amount of dirt, while for short rifles, a relatively smaller initial cleaning agent usage is used to accommodate the less dirt. When cleaning the receiver, the rifle is laid flat or slightly tilted to facilitate component removal and ensure that the cleaning agent fully covers the gaps. The receiver area typically retains a relatively large amount of gunpowder residue, carbides, and other dirt. When cleaning the barrel area, typically... The gun muzzle will be tilted downwards at a certain angle, creating a slope in the barrel to facilitate the discharge of cleaning agent and dirt. The barrel area usually retains relatively little dirt. Through the control component 5, the placement angle of the gun can be automatically identified according to the different placement angles of the receiver and barrel. Based on different placement angles, the amount of cleaning agent used when cleaning different parts of the receiver and barrel can be automatically adjusted. On the basis of the cleaning agent discharge amount limited by the control component 4, the cleaning component 3 can be further adaptively adjusted to ensure the cleaning and maintenance effect of the gun.

[0021] The support assembly 2 includes two slide blocks 21 that are slidably disposed with the bracket 11. A sliding member 22 is slidably disposed through the slide block 21. A mounting block 23 is fixedly disposed at the upper end of the sliding member 22. A rotating frame 24 is slidably disposed on the upper side of the mounting block 23. A mounting seat 25 is rotatably disposed on the upper side of the rotating frame 24. A support block 26 is slidably disposed inside the mounting seat 25. A lead screw 29 that is threaded to the mounting seat 25 is rotatably disposed on the lower side of the support block 26. A rotating groove 210 is opened on the lower side of the support block 26. The upper end of the lead screw 29 is rotatably disposed in the rotating groove 210 and the upper end of the lead screw 29 is adapted to the rotating groove 210. A first rack 211 is fixedly disposed on the lower side of the support block 26.

[0022] A toggle member 221 is slidably mounted on one side of the slide 21. A guide groove 222 is provided on the lower side of the slide 21. The toggle member 221 slides along the guide groove 222, which can support and guide the toggle member 221. A fourth spring 234, which is fixed to the slide 21, is fixed at equal intervals on one side of the toggle member 221. An anti-slip pad is fixed on the inner side of the toggle member 221. Initially, under the elastic force of the fourth spring 234, the toggle member 221 presses against one side of the bracket 11, restricting the position of the slide 21. By pressing the toggle member 221 outward, the toggle member 221 moves away from the bracket 11. The compression of the four springs 234 allows the slide 21 to slide along the bracket 11, adjusting its position to fit different firearm lengths. After adjustment, releasing the actuating element 221 causes the actuating element 221 and its inner anti-slip pad to press against one side of the bracket 11 under the elastic force of the fourth spring 234, thus restricting the sliding of the slide 21. Furthermore, by pressing the actuating element 221 to disengage it from one side of the bracket 11, the slide 21 can be removed from the bracket 11, and the tool box 12 can also be removed from the bracket 11 for convenient storage of the device.

[0023] Both inner sides of the mounting base 25 are provided with sliding grooves 28 that are adapted to the support block 26. The support block 26 slides along the sliding grooves 28, which can guide and limit the sliding of the support block 26. A housing 212 is fixedly provided on the lower side of the mounting base 25. A gear 213 that meshes with the first rack 211 is provided in the housing 212. The first rack 211 movably passes through the mounting base 25 and the housing 212. An L-shaped rod 214 fixed to the bottom end of the mounting base 25 is rotatably provided in the middle of the gear 213. Second racks 215 are meshed with the upper and lower sides of the gear 213. Limiting grooves 218 adapted to the second racks 215 are provided on the lower side of the housing 212 and the mounting base 25. The upper second rack 215 slides along the limiting groove 218 on the lower side of the mounting base 25, and the lower second rack 215 slides along the housing 212. The lower limiting groove 218 slides, which can guide and limit the two second racks 215 respectively. The upper second rack 215 has a first connecting rod 216 fixed at one end, and the lower second rack 215 has a second connecting rod 217 fixed at one end. The first connecting rod 216 and the second connecting rod 217 move upward through the mounting base 25, the support block 26 and the first clamping pad 27 to ensure the movement of the first connecting rod 216 and the second connecting rod 217. The upper ends of the first connecting rod 216 and the second connecting rod 217 are both fixed with clamping blocks 219. The clamping block 219 has a second clamping pad 220 fixed on one side, and the support block 26 has a first clamping pad 27 fixed on the outside. The first clamping pad 27 and the second clamping pad 220 can prevent the clamping block 219 and the support block 26 from causing large wear to the firearm after the firearm is clamped and fixed. In use, the firearm is supported on the support blocks 26 on both sides. Then, by rotating the lead screw 29 and passing through the rotating groove 210, the lead screw 29 drives the support block 26 to slide downward along the sliding groove 28, causing the first rack 211 to move downward synchronously with the support block 26, thereby driving the gear 213 to rotate. This causes the upper and lower second racks 215 to move closer to each other, which in turn causes the first connecting rod 216 and the second connecting rod 217 to drive the clamping blocks 219 on both sides to move closer to each other, thereby clamping and fixing the firearm. Thus, after the firearm is placed on the support blocks 26 on both sides, it can be clamped simply by rotating the lead screw 29, which makes it convenient for maintenance personnel to clamp and fix the firearm.

[0024] A mounting shell 223 is fixedly mounted on the upper side of the slide block 21. A first toothed block 225 is slidably disposed inside the mounting shell 223, passing through one side of the slide block 21, so that the first toothed block 225 can pass through one side of the slide block 21 and engage with a toothed groove on one side of the slider 22. A first spring 226, which is fixedly mounted inside the mounting shell 223, is fixedly mounted on one side of the first toothed block 225. A pull rod 224, which slidably passes through one side of the mounting shell 223, is fixed on one side of the first toothed block 225. A toothed groove adapted to the first toothed block 225 is provided on one side of the slider 22. Initially, under the elastic force of the first spring 226, the first toothed block 225 is engaged in the toothed groove on one side of the slider 22, restricting the downward movement of the slider 22. During use, the mounting block 23 can be moved upward. Moving the slider 22 upward causes the first toothed block 225 to move along the lower inclined surface of the toothed groove on one side of the slider 22, which can adjust the height position of the mounting block 23. After adjustment, pressing the mounting block 23 downward slightly causes the first toothed block 225 to engage in the toothed groove on one side of the slider 22, thereby restricting the downward movement of the slider 22. Alternatively, pulling the lever 224 outward can disengage the first toothed block 225 from the toothed groove on one side of the slider 22, allowing the slider 22 to move upward, then releasing the lever 224, and then pressing the mounting block 23 downward slightly, thereby adjusting the height position of the mounting blocks 23 on both sides. This allows the tilt angle of the firearm in the length direction to be adjusted after it is placed on the support blocks 26 on both sides.

[0025] Mounting block 23 is slidably provided with a second toothed block 227 on the lower side of rotating frame 24. A second spring 228 fixedly mounted on the lower side of the second toothed block 227 and fixedly mounted on the mounting block 23 is provided with a pressure rod 229 that movably passes through the mounting block 23 on one side of the second toothed block 227. The lower side of rotating frame 24 is provided with a toothed groove that matches the second toothed block 227. Mounting block 23 is provided with a connecting shell 230 fixedly mounted on one side of the pressure rod 229. A stop block 231 is slidably provided inside the connecting shell 230. A third spring 232 fixedly mounted on one side of the stop block 231 and fixedly mounted on the connecting shell 230 is provided with a third spring 232 fixedly mounted on one side of the stop block 231 and fixedly mounted on the mounting block 232. The insert 233 is provided with a slot on one side that matches the stop 231. Initially, under the elastic force of the second spring 228, the second tooth block 227 is inserted into the tooth groove on the lower side of the rotating frame 24. Under the elastic force of the third spring 232, the stop 231 is inserted into the insertion hole on one side of the insert 233. At this time, the stop 231 is located on the lower side of the pressure rod 229, which can prevent the pressure rod 229 and the second tooth block 227 from moving downward, prevent the second tooth block 227 from disengaging from the tooth groove on the lower side of the rotating frame 24, and thus restrict the sliding of the rotating frame 24 along the mounting block 23, that is, restrict the rotation of the rotating frame 24. When it is necessary to rotate the rotating frame 24 to adjust the angle of the cross-section after the gun is clamped, the stop block 231 can be pulled away from the insert block 233 to move it away from the downward movement of the pressure rod 229. Then, the pressure rod 229 is pressed to move the second toothed block 227 downward and disengage it from the toothed groove on the lower side of the rotating frame 24, thus releasing the restriction on the rotating frame 24. After releasing the stop block 231, under the elastic force of the third spring 232, the stop block 231 is inserted back into the insertion hole of the insert block 233. At this time, the stop block 231 is located above the downward-moved pressure rod 229, restricting the upward movement of the pressure rod 229 and keeping the rotating frame 24 rotatable. Similarly, the restriction of the second toothed block 227 on the rotating frame 24 on the other side is released. The function is to adjust the angle position of the cross section after the firearm is clamped by rotating the rotating frame 24 on both sides. After the adjustment is completed, the restriction of the stop block 231 on the pressure rod 229 is released, so that the second tooth block 227 moves upward under the elastic force of the second spring 228. Then, the rotating frame 24 is rotated slightly to ensure that the second tooth block 227 is engaged with the tooth groove on the lower side of the rotating frame 24. The stop block 231 restricts the downward movement of the pressure rod 229, thereby restricting the rotation of the rotating frame 24 and maintaining the adjusted angle position. Combined with the angle adjustment in the length direction of the firearm, it is convenient to adjust the firearm at multiple angles, so as to facilitate the cleaning and maintenance of different parts of the firearm by maintenance personnel and improve its applicability. After the firearm is clamped by the clamping blocks 219 on both sides, if it is necessary to adjust the angle position of the firearm in the length direction, the lead screw 29 on one side can be rotated in the opposite direction to release the clamping effect of the two clamping blocks 219 on one side. Then, by moving the sliding member 22 on this side upward or downward, the angle position of the firearm in the length direction can be adjusted. After the adjustment is completed, the lead screw 29 on this side can be rotated again to clamp the firearm. Thus, it is not necessary to remove the firearm from the support blocks 26 on both sides after it is clamped and then adjust it. It is convenient to adjust the firearm to the required angle position, which is convenient for maintenance personnel to use and operate. Moreover, the rotation setting of the mounting base 25 and the rotating frame 24 can prevent the firearm from being worn too much when adjusting the firearm at multiple angles, and can ensure the support of the support block 26 on the bottom of the firearm and the clamping and fixing of the firearm by the two clamping blocks 219.

[0026] Example 2 like Figures 13 to 21 As shown, in this second embodiment, the other structures remain unchanged, but the difference from the first embodiment is: The cleaning component 3 includes a mounting part 31. A support part 324 is fixedly mounted on the lower side of the mounting part 31. The support part 324 is located on the upper side of the bracket 11. A cylinder 32 and a liquid storage cylinder 37 are fixedly mounted on the upper side of the mounting part 31. The cylinder 32 and the liquid storage cylinder 37 contain cleaning agent. A cap 39 is threadedly provided at the liquid inlet on the upper side of the liquid storage cylinder 37. By rotating and unscrewing the cap 39, cleaning agent can be added to the liquid storage cylinder 37 through the liquid inlet on the upper side of the liquid storage cylinder 37. Then, the cap 39 is rotated and screwed back on. A connecting pipe 38 is fixedly connected between the liquid storage cylinder 37 and the cylinder 32. A one-way valve is installed on the side of the connecting pipe 38 near the cylinder 32, which allows the cleaning agent in the liquid storage cylinder 37 to enter the cylinder 32 through the connecting pipe 38 and prevents the cleaning agent in the cylinder 32 from entering the liquid storage cylinder 37 through the connecting pipe 38. A piston 33 is slidably provided inside the cylinder 32. A push rod 34 is fixedly mounted on one side of the piston 33 and extends through one side of the cylinder 32. A telescopic end of a first electric push rod 35 is fixedly mounted on one side of the push rod 34. The first electric push rod 35 is fixedly mounted on the upper side of the mounting part 31. A drain pipe 36 is fixedly connected to one side of the cylinder 32. A conical block 320 is fixedly mounted on the lower side of the drain pipe 36. A conical hole is provided in the middle of the conical block 320. A block block 321 is provided on the lower side of the conical block 320. The upper side of the block block 321 is set to be conical to match the conical block 320. A sixth spring 322 is fixedly mounted on the lower side of the block block 321 and is fixed to the bottom end of the drain pipe 36. Initially, under the elastic force of the sixth spring 322, the block block 321 abuts against the inner side of the conical block 320 to seal the conical hole of the conical block 320 and prevent the detergent from flowing out. When cleaning the firearm by applying cleaning agent to a piece of tissue paper, the first electric push rod 35 can be controlled to operate. The telescopic end of the first electric push rod 35 drives the push rod 34 and piston 33 to move closer to the drain pipe 36, causing the cleaning agent in the cylinder 32 to flow downward through the drain pipe 36. It can also exert downward pressure on the block 321, causing the block 321 to disengage downward from the conical block 320. The sixth spring 322 is compressed, causing the conical hole of the conical block 320 to open, allowing the cleaning agent pushed by the piston 33 to flow downward out of the drain pipe 36 and onto the tissue paper placed below the outlet of the drain pipe 36. Subsequently, the telescopic end of the first electric push rod 35 drives the push rod 34 and piston 33 to move in the opposite direction and reset, allowing the cleaning agent in the reservoir 37 to be drawn into the cylinder 32 through the connecting pipe 38 to replenish the cleaning agent in the cylinder 32.

[0027] Mounting component 31 is located on one side of cylinder 32 and has a first electromagnetic block 310. A movable block 311 is located on one side of the first electromagnetic block 310, and a fixed block 313 is fixed to one side of the movable block 311 and fixed to the mounting component 311. A magnetic block 312, which repels the first electromagnetic block 310, is fixed to one side of the movable block 311. A guide rod 315, symmetrically fixed to the other side of the movable block 311 and slidingly penetrating the fixed block 313, guides the movement of the movable block 311. A fifth spring 314, fixed to the fixed block 313, is fixed to one side of the movable block 311. A pressing rod 316 is fixed to one side of the push rod 34. A limit switch 317 is installed on the side of the movable block 311 near the pressing rod 316. The limit switch 317 is connected to the first electric push rod 311. 5. Electrical connection; A protective shell 319 is fixed on the upper side of the mounting component 31. The protective shell 319 can protect the first electromagnetic block 310, the moving block 311, the fixed block 313, the first electric push rod 35, the components of the control assembly 5 on the upper side of the mounting component 31, the second electric push rod 43, etc. on its inner side. The cylinder 32 penetrates one side of the protective shell 319. A through hole is provided on the side end of the protective shell 319 to dissipate heat inside the protective shell 319. A filter screen can be provided inside the through hole to prevent external debris from entering the protective shell 319. A placement box 318 is provided on the upper side of the mounting component 31. A pressure sensor 323 is installed on the lower side of the mounting component 31 and is electrically connected to the first electromagnetic block 310. During initial use, the first electromagnetic block 310 generates a repulsive force on the magnetic block 312 after being energized, causing the moving block 311 to move closer to the pressing rod 316. The fifth spring 314 is compressed. When the first electric push rod 35 is operated to discharge the cleaning agent in the cylinder 32 through the drain pipe 36, the telescopic end of the first electric push rod 35 drives the push rod 34 to move, and at the same time, it can drive the pressing rod 316 to move. When the pressing rod 316 presses against the limit switch 317, it will control the telescopic end of the first electric push rod 35 to stop extending, and control the first electric push rod 35 to drive the push rod 34 to move in the opposite direction to reset. After wiping the firearm with a tissue soaked in detergent, the tissue is placed in the storage box 318. If the pressure sensor 323 detects a change in gravity, it indicates that a lot of dirt has been wiped away, resulting in a relatively small current in the circuit connected to the pressure sensor 323. Consequently, the magnetism of the first electromagnetic block 310 is weak, and its repulsive effect on the magnetic block 312 is small. This results in a larger distance between the moving block 311 and the pressing rod 316 compared to the initial state. Therefore, the extension end of the first electric push rod 35 can move the push rod 34 a greater distance before the pressing rod 316 presses down to the limit. The position switch 317 can increase the discharge of cleaning agent to accommodate a larger amount of dirt, ensuring effective cleaning of the firearm. When the amount of dirt wiped off is relatively small, the increase in the discharge of cleaning agent compared to the initial state can be smaller to accommodate the cleaning of the firearm. If the pressure sensor 323 does not detect a change in gravity, the magnetism of the first electromagnetic block 310 will not be adjusted. This indicates that the amount of dirt wiped off is small or there is no dirt. In this case, the discharge of cleaning agent will be maintained at the small discharge rate of the initial state, thereby effectively reducing the possibility of excessive use of cleaning agent.

[0028] The adjustment assembly 4 includes a pressure plate 41 fixedly mounted on the lower side of a slide block 21. Both ends of the pressure plate 41 near the touch switch 42 are set with arc-shaped end faces to facilitate contact with the touch switch 42. Two touch switches 42 are mounted on the side of the bracket 11 near the pressure plate 41. The touch switches 42 are electrically connected to the second electric push rod 43. The telescopic end of the second electric push rod 43 is fixedly mounted on one side of the first electromagnetic block 310. The second electric push rod 43 is fixedly mounted on the upper side of the mounting component 31. In use, by moving the slide 21 on one side of the pressure plate 41 closer to or further away from the slide 21 on the other side, the distance between the two slides 21 is adjusted to accommodate the different lengths of the long and short guns. For the short gun, after moving the slide 21 on one side of the pressure plate 41, the pressure plate 41 can touch the touch switch 42 on the side away from the pressure plate 41, indicating that the short gun is being cleaned. This will control the extension end of the second electric push rod 43 to extend, causing the first electromagnetic block 310 to move closer to the magnetic block 312. As a result, when the cleaning agent is discharged through the cleaning component 3, the repulsive force of the first electromagnetic block 310 on the magnetic block 312 can be relatively large, thus allowing the pressure rod 316 to move relatively little. The distance is such that the limit switch 317 can be triggered, so that for short guns, the amount of cleaning agent discharged is relatively small, which can accommodate the relatively small amount of dirt on short guns; conversely, for long guns, after moving the slide 21 on one side of the pressure plate 41, the pressure plate 41 can be triggered to the touch switch 42 on the side near the pressure plate 41, which indicates that the long gun is being cleaned. This will control the extension end of the second electric push rod 43 to shorten, causing the first electromagnetic block 310 to move away from the magnetic block 312. This makes the repulsive effect of the first electromagnetic block 310 on the magnetic block 312 relatively small, so that the moving block 311 moves a relatively small distance close to the pressure rod 316, and thus the amount of cleaning agent discharged is relatively large, which can accommodate the relatively large amount of dirt on long guns.

[0029] The control component 5 includes a second electromagnetic block 51 and a third electromagnetic block 52 fixed on the upper side of the mounting component 31. Distance sensors 53 are mounted on the lower sides of both slide blocks 21. The front and rear sides of the lower end of the slide block 22 are provided with protruding edges (e.g., ...). Figure 9 or Figure 13 As shown, the distance sensor 53 is used to detect the distance between the protruding parts on both sides of the lower end of the slider 22 and the lower side of the slide block 21. The slide block 21 has symmetrically arranged protrusions on the lower side. When the slider 22 moves upward, the protrusions can block the protruding parts on both sides of the lower end of the slider 22 to prevent the protruding parts of the slider 22 from pressing against the distance sensor 53 and causing damage to the distance sensor 53. The distance sensor 53 on the lower side of the slide block 21 on the side where the gun handle is placed is electrically connected to the second electromagnetic block 51, and the distance sensor 53 on the lower side of the slide block 21 on the side where the gun barrel is placed is electrically connected to the third electromagnetic block 52. A pressure switch 54 is installed on one side of the clamping block 219, and a pressure switch 54 is also installed on one side of each clamping block 219 on the upper side of the two slide blocks 21. An adsorption block 55 is slidably mounted on the upper side of the mounting part 31. The second electromagnetic block 51 and the third electromagnetic block 52 can both generate an adsorption effect on the adsorption block 55. A first guide groove adapted to the adsorption block 55 is provided on the upper side of the mounting part 31. The adsorption block 55 is slidably mounted along the first guide groove, which can guide and limit the movement of the adsorption block 55. A seventh spring 56 fixed to the mounting part 31 is fixed on one side of the adsorption block 55, and a fixing shell 57 is fixed on one side of the adsorption block 55. A fourth electromagnetic block 58 is fixed inside the fixing shell 57. A limiting tooth block 59 that is attracted to the fourth electromagnetic block 58 is slidably provided on the inner side of the shell 57. An eighth spring 510 that is fixed to the inner side of the fixed shell 57 is symmetrically fixed on one side of the limiting tooth block 59. A toothed rod 511 that cooperates with the limiting tooth block 59 is slidably provided on the upper side of the mounting member 31. A second guide groove that is adapted to the toothed rod 511 is provided on the upper side of the mounting member 31. The toothed rod 511 is slidably provided along the second guide groove, which can guide and limit the movement of the toothed rod 511. Initially, the fourth electromagnetic block 58 is in the energized state, attracting the limiting tooth block 59 to move away from the toothed rod 511, so that the limiting tooth block 59 does not engage with the toothed rod 511, and the eighth spring 510 is compressed. Mounting bracket 512 is fixedly mounted on the upper side of mounting component 31. Metal strip 513 and slide rod 514 are fixedly mounted on the inner side of mounting bracket 512. Sliding piece 515 is slidably mounted on the outer side of slide rod 514 and is slidably mounted with metal strip 513. Sliding piece 515 is made of conductive material. One side of toothed rod 511 is fixed with sliding piece 515. One side of toothed rod 511 is fixed with reset spring 516 fixed with mounting component 31. Metal strip 513 is electrically connected to first electromagnetic block 310. The resistance value of metal strip 513 on the side of slide rod 515 near fixed shell 57 is connected to the circuit.

[0030] The firearm is placed on the support blocks 26 on both sides. By adjusting the upward movement distance of the sliding parts 22 on both sides, the firearm is laid flat or slightly tilted to facilitate cleaning of the receiver. The distances detected by the distance sensors 53 on both sides are reduced, which increases the current in the circuit connected to the distance sensors 53. This increases the attraction of the second electromagnetic block 51 and the third electromagnetic block 52 on the adsorption block 55. After the firearm is laid flat or slightly tilted, the two clamping blocks 219 on the two slide blocks 21 respectively clamp and fix the handle and the barrel. At the same time, the pressure switch 54 is pressed to de-energize the fourth electromagnetic block 58. Under the elastic force of the eighth spring 510, the limiting tooth block 59 and the toothed rod 511 are engaged and fixed. After cleaning the receiver, when cleaning the barrel, the barrel can be tilted downwards by moving the slider 22 on one side of the grip upwards or downwards on the other side of the barrel, facilitating cleaning. During this process, the clamping block 219 on one side of the slide 21 releases its grip on the firearm, while maintaining the pressure switch 54 on the other side of the slide 21 in a resisting state, keeping the limiting tooth block 59 engaged with the toothed rod 511. During the downward tilting of the barrel, the upward movement of the slider 22 on one side of the grip reduces the distance detected by the distance sensor 53 on one side of the grip, increasing the current in the circuit connected to the distance sensor 53, thereby increasing the attraction generated by the second electromagnetic block 51. The adsorption effect of block 55 increases. Conversely, the downward movement of the sliding member 22 on one side of the barrel, through the distance sensor 53 on one side of the barrel, can reduce the adsorption effect of the third electromagnetic block 52 on the adsorption block 55, causing the adsorption block 55 to move closer to the second electromagnetic block 51. This can drive the toothed rod 511 to move synchronously, and the return spring 516 to compress, causing the slider 515 to move closer to the fixed shell 57. This reduces the resistance of the metal strip 513 connected to the circuit, increases the current in the circuit, and increases the repulsive effect of the first electromagnetic block 310 on the magnetic block 312. This reduces the amount of cleaning agent discharged by the cleaning component 3 to accommodate the relatively small amount of dirt remaining in the barrel area. When the barrel is tilted downwards at a large angle, the sliding member 22 on the grip side moves upwards by a relatively large distance, or the sliding member 22 on the barrel side moves downwards by a relatively large distance. This causes the adsorption block 55 to move closer to the second electromagnetic block 51 by a relatively large distance, and the toothed rod 511 and the slider 515 to move by a relatively large distance. Consequently, the first electromagnetic block 310 has a relatively strong repulsive effect on the magnetic block 312, resulting in a relatively small amount of cleaning agent discharged from the cleaning component 3. When the barrel is tilted downwards at a large angle, the cleaning agent and dirt mixture flows more easily along the tilt direction and is discharged, leaving relatively little residue. This reduces the accumulation or retention in the barrel, thus reducing the amount of cleaning agent used. This is compatible with the relatively small amount of cleaning agent discharged from the cleaning component 3, preventing excessive use of cleaning agent.
