Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and more specifically to a metal processing apparatus for processing high-rise steel structures. Background Technology

[0002] Steel structures are structures composed of steel materials, primarily using structural steel (such as H-beams and I-beams) and steel plates to form components (such as beams, columns, and trusses). These components are connected by welding, bolts, or rivets. They are characterized by high strength, light weight, suitability for large-span, high-rise, and heavy buildings, industrialized production, and efficient on-site assembly. The equipment required for steel structure production and processing mainly includes cutting equipment, forming and welding equipment, and auxiliary processing and handling equipment. Cutting equipment primarily includes mechanical cutting, gas cutting, plasma cutting, and laser cutting.

[0003] A search revealed Chinese Patent Publication No. CN219234104U, which discloses a cutting device for processing high-rise steel structures. The device includes a steel pipe, a base plate, and clamping blocks. Each of the four corners of the base plate has a vertical pole, and the upper end of each pole has a top plate. The base plate and top plate each contain a cavity one and a cavity two, respectively. A dual-axis motor and a drive motor are respectively installed in the cavity one and cavity two. The output end of each dual-axis motor has a screw rod rotatably connected to the inner wall of cavity one. Moving blocks are threaded onto both sides of the screw rod one. Guide plates are provided at the lower ends of both moving blocks one. The base plate has a guide groove at the lower end of cavity one that mates with the guide plate, and a stroke groove within the base plate that mates with the moving blocks one. Electric push rods are provided at the upper ends of both moving blocks one, and lifting blocks are provided at the upper ends of the electric push rods one. The advantages of this invention compared to existing technologies are: it can clamp steel pipes of different sizes and can limit the movement of both ends of the steel pipe.

[0004] The actual operation process is as follows: First, adjust the distance between the two clamping blocks, then place the steel structure to be processed, fix it with the clamps, and then cut it. After one cut, release the clamps and remove the cut steel structure. When it is necessary to cut a long section of steel structure into multiple shorter sections, the above operation process needs to be repeated manually multiple times. The operation is cumbersome, the cutting efficiency is low, and it is not convenient to complete precise cutting according to actual needs to obtain shorter steel structures with precise dimensions.

[0017] The spacing between the two arc-shaped scrapers and the two push blocks is adjusted by a drive assembly to accommodate guide rods and screws of different diameters. The drive assembly is connected to the positioning block.

[0018] A further improvement of the technical solution of the present invention is that: in the initial stage, the distance between the two push blocks is the same as the minor diameter of the second screw, and the cross section of the push block along the axial direction of the second screw fits with the cross section of the thread clearance of the second screw along the axial direction of the second screw.

[0019] Each of the arc-shaped scrapers is inclined to the side away from the positioning block, and the two arc-shaped scrapers are spliced ​​together facing each other and completely fit the outer surface of the guide rod.

[0020] A further improvement of the technical solution of the present invention is that: the driving component includes a bidirectional telescopic rod, and the two output ends of the bidirectional telescopic rod for driving the push block are respectively movably connected to the bottom plate and the top plate. The two push blocks on the same side are respectively installed on the bottom plate and the top plate. There is a distance difference between the push block installed on the bottom plate and the push block installed on the top plate along the central axis of the screw.

[0021] The two output ends of the bidirectional telescopic rod used to drive the arc-shaped scraper are movably connected to mounting plates, and the arc-shaped scraper is mounted on the mounting plates.

[0028] 1. This invention provides a metal processing device for high-rise steel structure processing. If the position of the positioning block remains unchanged, the length of the cut steel structure will be consistent. Moreover, a shorter steel structure with more accurate dimensions can be obtained according to the distance from the positioning block to the cutting groove. If it is necessary to cut steel structures of different lengths, it is only necessary to adjust the distance between the positioning block and the cutting groove.

The zero scale line of the scale line one is set at the intersection of the cutting surface of the cutting blade in the cutting groove and the guide rod two, and then the depth of the positioning groove moving closer to the positioning block. This is the zero scale line of the scale line one. At this time, the value read by the scale line one on the guide rod two on the side of the positioning block closer to the cutting frame during the movement is the moving distance of the positioning block, which is also the distance between the positioning block and the cutting surface of the cutting groove, and also the length of the cut steel structure.

[0030] 3. This invention provides a metal processing device for high-rise steel structure processing. Through the action of the arc-shaped scraper and the pusher, the surface of the screw rod and the guide rod can be processed during the movement of the positioning block. This not only removes solid particles, but also cleans the lubricating oil with increased adhesion at low temperatures.

[0043] The present invention will be further described in detail below with reference to embodiments:

[0044] Example:

[0045] like Figure 1-11 As shown, the present invention provides a metal processing device for processing high-rise steel structures, including a cutting blade 1, a protective cover 2 movably connected to the outside of the cutting blade 1, a drive device 3 for driving the cutting blade 1 to rotate fixedly connected to the surface of the protective cover 2, the drive device 3 being prior art, typically a motor, for driving the cutting blade 1 to rotate, and also including a base 5, a base 6 fixedly connected to one side of the base 5, and brackets 7 fixedly connected to the upper surfaces of both the base 5 and the base 6, and a drive mechanism 1 for driving the cutting blade 1 to move in multiple directions is provided between the two brackets 7.

[0046] The drive mechanism includes a lifting rod 4 fixedly connected to the protective cover 2. The lifting rod 4 is existing technology and includes an electric or pneumatic telescopic device. The output end of the lifting rod 4 is fixedly connected to the surface of the protective cover 2 to drive the cutting blade 1 and the protective cover 2 to move in the vertical direction. A drive block 20 is fixedly connected to the lifting rod 4. A guide rod 21 and a screw 22 are movably connected to the inner wall of the drive block 20. The two ends of the guide rod 21 are fixedly connected to the bracket 7, and the two ends of the screw 22 are movably connected to the bracket 7. The screw 22 is threadedly connected to the drive block 20. A drive device 2 is fixedly connected to the bracket 7. The drive device 2 is existing technology and includes a motor or other equipment that can drive the screw 22 to rotate and related accessories. The drive device 2 can drive the screw 22 to rotate. With the action of the guide rod 21, the drive block 20 drives the cutting blade 1 and the protective cover 2 to move laterally along the guide rod 21 and the screw 22.

[0047] A cutting frame 8 is fixedly connected to the side of the base 1 5 near the base 2 6. A cutting groove 9 is formed between the cutting frame 8 and the base 1 5 to facilitate cutting by the cutting blade 1. Both the base 1 5 and the cutting frame 8 are provided with grooves for placing steel structures. The base 1 5 is hollow inside and is provided with a second driving mechanism that drives the steel structure placed in the groove to move towards the base 2 6.

[0048] The second drive mechanism includes multiple parallel drive drums 23. Both ends of the multiple drive drums 23 are movably connected to the second connecting plate 24. The second connecting plate 24 is fixedly connected to the inner wall of the base 5. Each drive drum 23 is fixedly connected to the end of the drive gear 25. The multiple drive gears 25 on the same side are connected by a transmission chain 26. The second connecting plate 24 is also fixedly connected to the third drive device. The third drive device is existing technology and includes a motor or other equipment that can drive the drive drum 23 to rotate and related accessories. When the steel structure is placed on the groove and the drive drum 23, after one cut is completed, the auxiliary clamping mechanism is released. At this time, the third drive device drives the drive drum 23 to rotate. Using friction, the steel structure is moved closer to the positioning block 27. This avoids the need to repeatedly cut, remove the clamp, and manually repeat the process multiple times, which leads to cumbersome operation and low cutting efficiency.

[0049] A positioning block 27 is movably connected between base 26 and base 15. The positioning block 27 has a positioning groove 28 with the opening facing upward, which facilitates the removal of the cut steel structure. The positioning groove 28 is collinear with the lowest point of the inner wall of the groove. When the positioning block 27 moves toward or away from the cutting groove 9, the distance between the positioning block 27 and the cutting groove 9 is the length of the cut steel structure.

[0050] An auxiliary clamping mechanism is movably connected to one side of the protective cover 2. The bottom of the auxiliary clamping mechanism is lower than the bottom of the cutting blade 1. The protective cover 2 and the auxiliary clamping mechanism are movably connected. First, the distance between the positioning block 27 and the cutting groove 9 is adjusted according to the cutting needs. Then, the steel structure to be cut is placed in the groove, with one end abutting against the positioning groove 28. At this time, the cutting blade 1 and the auxiliary clamping mechanism can be driven to fall together by the action of the drive mechanism. The auxiliary clamping mechanism abuts against the steel structure to be cut first and cooperates with the base 5 to clamp and fix the steel structure. At this time, the drive mechanism drives the cutting blade 1 to continue falling to perform gas cutting on the steel structure. After the cutting is completed, the drive mechanism... When the lifting rod 4 is raised, the protective cover 2 will drive the auxiliary clamping mechanism to rise together with the cutting blade 1 when it leaves the upper surface of the steel structure. The auxiliary clamping mechanism will then drive the steel structure to be cut, which is placed on the base 5, to move closer to the positioning block 27 until the steel structure abuts against the inner wall of the positioning groove 28. At this point, cutting can continue. The position of the positioning block 27 remains unchanged, so the length of the cut steel structure is consistent. The shorter steel structure with more precise dimensions can be obtained based on the distance from the positioning block 27 to the cutting groove 9. If it is necessary to cut steel structures of different lengths, the distance between the positioning block 27 and the cutting groove 9 can be adjusted.

[0051] Furthermore, the auxiliary clamping mechanism includes multiple connecting plates 11 and a counterweight clamping block 10 fixedly connected to one side of the protective cover 2. The counterweight clamping block 10 is heavier and has a counterweight function. Multiple connecting grooves 12 are opened on the side of the counterweight clamping block 10 and the connecting plates 11. The connecting plates 11 extend into the interior of the connecting grooves 12 and are movably connected to the inner wall of the connecting grooves 12.

[0052] The bottom of the counterweight clamp 10 is provided with a slot 14, the opening direction of the slot 14 is opposite to the opening direction of the groove, and a clamping plate 15 is movably connected to the inner wall of the slot 14.

[0053] When the drive mechanism 1 drives the cutting blade 1 and the auxiliary clamping mechanism to move downward together, the clamping plate 15 in the slot 14 first abuts against the steel structure to be cut. At this time, the cutting blade 1 continues to move downward. Under the action of the gravity of the counterweight clamping block 10, the clamping plate 15 generates a downward clamping force on the steel structure to be cut, which plays a role in fixing the position of the steel structure to be cut. When the cutting blade 1 continues to move downward, the supporting effect of the cutting blade 1 on the counterweight clamping block 10 through the connecting plate 11 disappears. At this time, the counterweight clamping block 10 does not move, and the cutting blade 1 continues to move downward relative to the counterweight clamping block 10 to complete the cutting. After the cutting is completed, the drive mechanism 1 drives the cutting blade 1 to rise. At this time, the connecting plate 11 moves upward along the connecting groove 12. When the connecting plate 11 moves upward with the cutting blade 1 to abut against the top of the connecting groove 12, the cutting blade 1 will drive the counterweight clamping block 10 to move upward together through the connecting plate 11 until the clamping plate 15 leaves the surface of the steel structure. At this time, the drive mechanism 2 can drive the steel structure to move a corresponding distance towards the positioning block 27 to facilitate the next cutting operation.

[0054] Furthermore, multiple adjusting rods 16 are fixedly connected to the upper surface of the clamping plate 15, and multiple sliding grooves 19 are correspondingly opened inside the counterweight clamping block 10. The adjusting rods 16 are movably connected to the sliding grooves 19. A limiting ring 13 is fixedly connected to the adjusting rod 16 inside the sliding groove 19. The sliding range of the adjusting rod 16 is limited by the limiting ring 13 to prevent slippage. A push plate 17 is fixedly connected to the outer surface of the adjusting rod 16 extending to the lower position inside the sliding groove 19. A spring 18 is sleeved on the outer surface of the adjusting rod 16 between the top of the push plate 17 and the top of the inner cavity of the sliding groove 19.

[0055] As the counterweight clamp 10 moves downwards along with the cutting blade 1, the clamping plate 15 first comes into contact with the steel structure. At this time, the cutting blade 1 continues to move downwards, and the counterweight clamp 10 loses the supporting effect of the connecting plate 11. Under its own weight, it continues to move downwards, causing the adjusting rod 16 and the push plate 17 to slide into the slide groove 19, compressing the spring 18 and causing it to undergo elastic deformation. When the bottom of the counterweight clamp 10 comes into contact with the upper surface of the base 5, the cutting blade 1 continues to move downwards to cut the steel structure. After the cutting is completed, the drive mechanism drives the cutting blade. 1. Move upward. Connecting plate 11 moves upward along connecting groove 12. At this time, counterweight clamping block 10 remains stationary. When cutting blade 1 moves upward to the point where connecting plate 11 abuts against the top of connecting groove 12, cutting blade 1 continues to move upward, which can drive counterweight clamping block 10 to move upward. The gravity pressure of counterweight clamping block 10 on clamping plate 15 gradually decreases. Clamping plate 15 rebounds under the action of compression spring 18, so that clamping plate 15 returns to its original position, so that clamping plate 15 has a certain vertical movement space, thereby allowing steel structures of different sizes to be cut within a certain range.

[0056] Furthermore, a second screw 29 and a second guide rod 30 are movably connected to the positioning block 27. The second screw 29 is threadedly connected to the positioning block 27. Both ends of the second screw 29 are movably connected to the first base 5 and the second base 6, respectively. Both ends of the second guide rod 30 are fixedly connected to the first base 5 and the second base 6, respectively. A scale line is provided on the second guide rod 30. A fourth driving device for driving the second screw 29 to rotate is fixedly connected to the second base 6. The fourth driving device is existing technology and includes a motor or other equipment that can drive the second screw 29 to rotate and related accessories. By driving the second screw 29 to rotate through the fourth driving device, the positioning block 27 can be moved along the second screw 29 and the second guide rod 30. With the help of the scale line 1 provided on the second guide rod 30, the position of the positioning block 27 can be clearly defined, and the distance between it and the cutting groove 9 is the length of the steel structure to be cut.

[0057] Furthermore, the zero mark of the first scale line is set as follows: the depth of the positioning groove 28 that the cutting surface of the cutting blade 1 intersects with the guide rod 20 in the cutting groove 9 is moved closer to the positioning block 27. This is the zero mark of the first scale line. At this time, the value read by the first scale line on the guide rod 20 on the side of the positioning block 27 that is closer to the cutting frame 8 during the movement is the moving distance of the positioning block 27, which is also the distance between the positioning block 27 and the cutting surface of the cutting groove 9, and is also the length of the cut steel structure.

[0058] The guide rod 21 is provided with a scale line 2. By setting the scale line 2 on the guide rod 21, the cutting blade 1 can be moved precisely to the position where the cutting blade 1 and the cutting surface of the cutting groove 9 are coplanar, or it can be moved along the guide rod 21 and the screw 22 to other positions to perform other cutting operations, thereby enhancing the applicability of the device.

[0059] Furthermore, on both sides of the positioning block 27, there are two opposing arc-shaped scrapers 31 and two push blocks 38. Each pair of opposing arc-shaped scrapers 31 clamps the guide rod 30 inside, and each pair of opposing push blocks 38 clamps the screw 29 inside.

[0060] The spacing between the two arc-shaped scrapers 31 and the two push blocks 38 is adjusted by the drive assembly to accommodate guide rods 30 and screws 29 of different diameters. The drive assembly is connected to the positioning block 27.

[0061] During steel structure cutting, a large amount of dust, debris, and other solid particles are generated. When these particles land on the surfaces of screw 29 and guide rod 30, they not only obstruct the scale line 1 on guide rod 30, affecting the accuracy of data reading, but also affect the smoothness of the reciprocating sliding of positioning block 27 along screw 29 and guide rod 30, causing jamming. Furthermore, to ensure smooth sliding of positioning block 27, lubricating oil is usually applied to the connection between screw 29, guide rod 30, and positioning block 27. However, in low-temperature environments, the adhesion of conventional lubricating oil increases while its fluidity decreases, causing a significant portion of the solid particles generated during cutting to adhere to the lubricating oil. In the case of lubricating oil, not only will the possibility of jamming increase, so regular cleaning is required. Cleaning lubricating grease that has absorbed solid particles in a low-temperature environment is difficult, time-consuming and laborious. Through the action of the arc-shaped scraper 31 and the push block 38, the surfaces of the screw 29 and guide rod 30 can be treated while following the movement of the positioning block 27. This can not only remove solid particles, but also clean the lubricating oil with increased adhesion at low temperatures. At the same time, it can also clean the large amount of solid particles attached to the lubricating oil, so as to avoid affecting the accuracy of the scale line 1 on the guide rod 30, thereby reducing the possibility of jamming, reducing the difficulty of cleaning, and ensuring the smooth progress of the steel structure cutting process.

[0062] Furthermore, in the initial stage, the distance between the two push blocks 38 is the same as the minor diameter of the screw 29. The cross section of the push block 38 along the axial direction of the screw 29 fits with the cross section of the thread gap of the screw 29 along the axial direction of the screw 29. With this setting, the push block 38 can enter the thread gap of the screw 29. As the screw 29 rotates and the positioning block 27 moves, the two opposing push blocks 38 will continuously clean the gap of the screw 29, preventing solid particles and lubricating grease from penetrating into the thread gap, which would increase the cleaning difficulty and reduce the cleaning efficiency.

[0063] Each arc-shaped scraper 31 is inclined to the side away from the positioning block 27, and the two arc-shaped scrapers 31 are spliced ​​together facing each other and completely fit the outer surface of the guide rod 30.

[0064] Guide rod 2 30 is typically a regular and smooth rod. It can be round or square, as long as the corresponding curved scraper 31 can be matched. Therefore, when the two curved scrapers 31 are joined together, the joint surface is completely in contact with the surface of guide rod 2 30. As the curved scraper 31 moves along guide rod 2 30, the lubricating grease adhering to the surface of guide rod 2 30 and containing solid particles is cleaned off. The curved scraper 31 is inclined, allowing the lubricating grease, solid particles, or a mixture thereof removed by the curved scraper 31 to be pushed away along the inclined surface, reducing the amount of accumulation at the contact point between the curved scraper 31 and guide rod 2 30. This avoids the increased possibility of jamming due to excessive accumulation of lubricating grease, solid particles, or a mixture thereof at the joint.

[0065] Furthermore, the drive assembly includes a bidirectional telescopic rod 33, which is existing technology and can be electrically or pneumatically driven. The output end of the bidirectional telescopic rod 33 can be extended or retracted. The two output ends of the bidirectional telescopic rod 33, used to drive the push blocks 38, are movably connected to a base plate 39 and a top plate 40, respectively. Two push blocks 38 on the same side are respectively mounted on the base plate 39 and the top plate 40. The push blocks 38 are detachably fixed to the base plate 39 and the top plate 40 by bolts. Different adaptable push blocks 38 can be selected according to different thread shapes. The push blocks 38 mounted on the base plate 39 and the push blocks 38 mounted on the top plate 40 on the same side... The push block 38 has a distance difference along the central axis of the screw 29. The part of the top plate 40 where the push block 38 is installed is curved, so that the two push blocks 38 on the same side have a distance difference along the central axis of the screw 29. Due to the existence of the thread helix angle and the inclined direction of the thread, the high point and low point of the same thread segment are not on the same plane perpendicular to the central axis of the screw. Therefore, the two push blocks 38 on the same side are installed in an alternating manner, so that the two push blocks 38 are located at the highest point and the lowest point of the same thread segment respectively. As the screw 29 rotates, the two push blocks 38 located at the high point and the low point can clean the same thread segment twice, thereby improving the cleaning effect.

[0066] The two output ends of the bidirectional telescopic rod 33 used to drive the arc-shaped scraper 31 are movably connected to the mounting plate 32. The arc-shaped scraper 31 is mounted on the mounting plate 32 and is detachably fixed to the mounting plate 32 by bolts. According to the guide rod 30 of different shapes or sizes, a suitable arc-shaped scraper 31 can be selected and installed on the mounting plate 32.

[0067] In the initial stage, all bidirectional telescopic rods 33 are in the extended state, so that the opposing arc-shaped scrapers 31 or push blocks 38 are separated from each other and do not abut against the guide rod 20 and the screw 29. When it is necessary to clean the surface of the screw 29 and the guide rod 20 or to keep the surface of the screw 29 and the guide rod 20 clean, first, according to the moving direction of the positioning block 27, adjust the extended end of the bidirectional telescopic rod 33 in the forward position of the moving direction of the positioning block 27 to retract, so as to drive the two arc-shaped scrapers 31 and the two push blocks 38 to approach each other until they abut against the guide rod 20 and the screw 29 respectively. At this time, the cutting solid particles, the lubricating grease with strong adhesion at low temperature, or the mixture of the two can be treated on the surface of the guide rod 20 and the screw 29.

[0068] Furthermore, both output ends of the bidirectional telescopic rod 33 are movably connected to a fine-tuning slide rod 34. The fine-tuning slide rod 34 is movably connected to the mounting plate 32, the bottom plate 39, and the top plate 40. One end of the fine-tuning slide rod 34 is fixedly connected to a fixing plate 36. Springs 35 are sleeved on the outer surfaces of the fine-tuning slide rod 34 located between the fixing plate 36 and the top plate 40, the fixing plate 36 and the bottom plate 39, and the mounting plate 32 and the fixing plate 36.

[0069] The two fixed plates 36 located on the same side of the arc-shaped scraper 31 are fixedly connected to the positioning block 27 through the connecting arm 37, and the two fixed plates 36 located on the same side of the push block 38 are movably connected to the positioning block 27 through the connecting arm 37 and the adjusting arm 41.

[0070] Within the stroke range of the bidirectional telescopic rod 33, spring 35 remains in a compressed state. When the bidirectional telescopic rod 33 retracts to its limit, the distance between the two arc-shaped scrapers 31 and the two push blocks 38 of the compressed spring 35 is closest, preventing them from getting any closer. In operation, under the action of the compressed spring 35, the arc-shaped scrapers 31 and push blocks 38 can be tightly pressed against the guide rod 20 and the screw 29. Furthermore, based on the elasticity of spring 35, the tightness between the two arc-shaped scrapers 31 and the two push blocks 38 has a certain degree of self-adjustment. When the arc-shaped scrapers 31 and push blocks 38 encounter obstacles during their movement... When the tightly adhered solid particles on the surfaces of screw 29 and guide rod 30 are removed by the method, the force generated at the contact surface will cause the arc-shaped scraper 31 and push block 38 to move upward along the fine-tuning slide rod 34 by a certain distance, and the spring 35 will continue to be compressed. At this time, the arc-shaped scraper 31 and push block 38 continue to move forward, and will pass over the tightly adhered solid particles that cannot be removed. After passing over them, under the action of the compressed spring 35, they will return to the state of clamping screw 29 and guide rod 30. This can protect the edges of the arc-shaped scraper 31 and push block 38 and ensure that subsequent cleaning work is not affected.

[0071] Furthermore, one end of the adjusting arm 41 is movably connected to the fixed plate 36 via a shaft, and the other end of the adjusting arm 41 is provided with a limiting groove 42. One of the limiting grooves 42 provided on the adjusting arm 41 is movably connected to the positioning block 27 via a limiting shaft 43.

[0072] Two limiting posts 44 are fixedly connected to the surface of the positioning block 27 by a screw 3 45. The direction of the screw 3 45 is consistent with the direction of the adjusting arm 41. The limiting groove 42 opened on the other adjusting arm 41 is movably connected to one of the limiting posts 44.

[0073] A push plate 47 is fixedly connected to one end of the adjusting arm 41, which is movably connected to the limiting post 44. The push plate 47 is movably connected to the screw 45. A limiting sleeve 48 is threadedly connected to the outer surface of the screw 45 between the push plate 47 and the limiting post 44, which is movably connected to the adjusting arm 41. A spring 46 is sleeved on the outer surface of the screw 45 between the push plate 47 and the limiting post 44, which is not movably connected to the adjusting arm 41. In the initial state, the spring 46 is compressed.

[0074] When it is necessary to adjust the included angle between the two opposing push blocks 38 and the screw 29 in the same group to accommodate screws 29 with different thread directions, first rotate the limiting sleeve 48 so that the limiting sleeve 48 moves closer to the fixed plate 36. At this time, the compressed spring 46 will push the adjusting arm 41 along the limiting post 44 and the limiting shaft 43, which are movably connected to the limiting groove 42, through the push plate 47. The moving distance is the same as the moving distance of the limiting sleeve 48. At this time, the adjusting arm 41 will push the two fixed plates 36 and the push blocks 38. The entire assembly deflects at a certain angle along the movable connection between the connecting arm 37 and the fixed plate 36. The movement distance of the limiting sleeve 48 varies, and the deflection angles between the two fixed plates 36 and the two push blocks 38 are also different. This can be adjusted according to actual needs. Moreover, the limiting sleeve 48 has a self-locking function. When the limiting sleeve 48 moves to the appropriate position, the deflection angles of the two fixed plates 36 and the two push blocks 38 are fixed, avoiding the subsequent cleaning process and cleaning effect being affected by the inconsistent deflection angles of the two fixed plates 36 and the two push blocks 38.
