[0002] The core function of an electric vehicle's speed throttle is to achieve linear adjustment of the motor speed. When the rider gently turns the throttle, the motor speed will increase slightly accordingly; as the throttle angle increases, the motor speed will also increase rapidly. The shape of the rod of an electric vehicle's speed throttle can be varied. The most common is cylindrical, which is easy to hold and turn. Some rods may have some special shape changes at both ends or in the middle. For example, one end may be stepped for precise positioning and installation with other components inside the throttle. Others may have a flat portion in the middle to facilitate close contact with Hall elements or other sensors to ensure the accuracy of signal transmission.

One end of the threaded rod is slidably connected to the inner side of the clamping seat, and the end of the connection block away from the knob is fixedly connected to a clamping plate, and the side of the clamping plate is fixedly connected to a clamping block; when clamping and fixing the workpiece, due to the different sizes of the workpieces and the different hardness of the materials, it is selected to clamp the side of the workpiece or the inner side of the workpiece according to the size of the workpiece and the hardness of the material. When it is necessary to clamp the side of the workpiece, the three clamping plates are used to abut against the side of the workpiece, and at the same time, after the threaded rod is threadedly connected to the inner side of the clamping seat, it is continuously rotated The knob drives the threaded rod to move on the clamping seat through the knob, and at the same time, the threaded rod drives the clamping plate to clamp the side of the workpiece through the rotating shaft, thereby clamping the side of the workpiece. At the same time, when grinding the plastic workpiece, since the material of the plastic workpiece is relatively soft, when grinding the workpiece, if the side of the plastic workpiece is clamped, when the plastic workpiece contacts and grinds with the grinding component, it is easy to cause the plastic workpiece to deform, thereby causing the grinding of the plastic workpiece to cause grinding deviation. When the plastic workpiece needs to be clamped, The rods of the electric vehicle speed control handle are mostly hollow, so that the three clamping blocks are supported and abutted against the inner wall of the plastic workpiece. The clamping blocks are driven by the stretching of the first spring so that the clamping blocks abut against the inner wall of the plastic workpiece. At the same time, by rotating the threaded rod, the threaded rod drives the clamping blocks to fit closely with the inner surface of the plastic workpiece to achieve precise positioning. The inner wall of the hollow shaft is a relatively stable supporting surface, which can better fix the workpiece and reduce displacement and shaking during processing, thereby improving processing accuracy and facilitating the grinding of the side of the plastic workpiece by the grinding component; Preferably, the collecting component comprises a collecting box, the side surface of the collecting box is fixedly connected to the inner side of the machine body, the top of the collecting box is fixedly connected to a mesh plate, the inner side of the collecting box is fixedly connected to a collecting plate, the bottom of the mesh plate is fixedly connected to a telescopic rod, the bottom of the telescopic rod is fixedly connected to a square frame, a second spring is sleeved on the telescopic rod, one end of the second spring is fixedly connected to the mesh plate, the other end of the second spring is fixedly connected to the square frame, an ejection mechanism is fixedly connected to the square frame, the ejection mechanism is concentrically arranged with the mesh of the mesh plate, and a filtering mechanism is fixedly connected to the inner side of the collecting box; when grinding the workpiece, the filtering mechanism is opened and the suction generated by the working of the filtering mechanism is used to remove the dust generated during grinding The waste gas and waste chips are sucked into the collection box through the mesh plate for collection, and the waste chips fall on the collection plate, which is convenient for the subsequent recycling of the waste chips. At the same time, when the waste chips enter the collection box through the mesh plate, the suction force generated by the operation of the filtering mechanism causes the square frame to move downward through the telescopic rod, so that the square frame drives the ejection mechanism to separate from the mesh holes of the mesh plate. When the collection work is completed and the filtering mechanism stops working, the square frame is reset by the stretching of the second spring, so that the square frame drives the ejection mechanism to move toward the mesh holes of the mesh plate, so that the ejection mechanism ejects the waste chips blocked at the mesh holes of the mesh plate, thereby preventing the waste chips from entering the collection box through the mesh plate, and part of the waste chips will be stuck at the mesh holes of the mesh plate, making it difficult to fall naturally. Preferably, the ejection mechanism comprises an ejection rod, the bottom of the ejection rod is fixedly connected to the top of the square frame, a notch is provided on the side of the ejection rod, a slider is slidably connected to the inner side of the notch, a connecting shaft is fixedly connected to the side of the slider, an ejector pin is fixedly connected to the top of the connecting shaft, a third spring is sleeved on the connecting shaft, the top of the third spring is fixedly connected to the bottom of the ejector pin, and the bottom of the third spring is fixedly connected to the top of the ejection rod; when the filtering mechanism stops working, the square frame is reset by the stretching of the second spring, driving the ejection rod to move toward the mesh of the mesh plate, so that the ejection rod drives the ejector pin to eject the waste chips stuck in the mesh, and at the same time, when the extrusion force between the ejector pin and the waste chips stuck in the mesh is greater than the stretching force of the third spring, the slider drives the ejector pin to move in the notch through the connecting shaft, so as to avoid excessive extrusion force between the ejector pin and the waste chips stuck in the mesh of the mesh, thereby causing extrusion damage to the ejector pin, and friction damage to the inner side of the mesh of the mesh, thereby causing the mesh aperture to become larger; Preferably, the filter mechanism comprises a filter tube, the side surface of the filter tube is fixedly connected to the inner side of the collection box, the side surface of the filter tube is evenly provided with through holes, both ends of the filter tube are fixedly connected to an air outlet plate, the side of the air outlet plate is fixedly connected to an air suction machine, the side of the air suction machine away from the air outlet plate is fixedly connected to a carbon powder box, both sides of the inner wall of the filter tube are fixedly connected to a fixing frame, the fixing frame is fixedly connected to a fixing rod, the middle part of the fixing rod is fixedly connected to a buffer assembly, the end of the fixing frame away from the air suction machine is fixedly connected to a fourth spring, and the other end of the fourth spring is fixedly connected to a contact assembly; by turning on the air suction machine, the suction force generated by the air suction machine when it is working, the exhaust gas and waste chips generated during the grinding of the workpiece are sucked into the collection box, and at the same time, the exhaust gas entering the collection box is continuously passed through the through hole into the filter tube by the air suction machine, so that the exhaust gas passes through the carbon powder box and is discharged through the air outlet plate, thereby avoiding the direct discharge of the exhaust gas generated by the grinding process, and the particulate matter and VOCs in the grinding exhaust gas are avoided. The pollutants such as the above will increase the concentration of pollutants in the air, resulting in a decrease in air quality. At the same time, the suction force generated by the air suction machine during operation causes the contact component to move on the fixed rod, and at the same time, the contact component can move and clean the inner wall of the filter tube. At the same time, when the contact component is reset by the movement of the fourth spring, the contact component contacts and collides with the buffer component, so that the contact component can be buffered. Preferably, the contact assembly includes a contact frame, a side of the contact frame is provided with a clearance hole, the inner side of the clearance hole is slidably connected to the side of the fixed rod, and scrapers are fixedly connected on both sides of the contact frame, the side of the scraper away from the contact frame is in contact with the inner side of the filter tube, and the side of the scraper is evenly provided with through holes; the suction force generated when the air suction machine is working causes the contact frame to drive the scraper to move on the fixed rod through the clearance hole, and at the same time enables the scraper to move and clean the inner wall of the filter tube; when the exhaust gas collection work is completed and the air suction machine stops working, the contact frame can be driven by the reset of the fourth spring, so that the scraper can perform secondary cleaning and scratching work on the inner side of the filter tube, thereby avoiding the exhaust gas passing through the filter tube for a long time, which will leave a large amount of smoke and dust impurities on the inner side of the filter tube, thereby causing corrosion to the inner wall of the filter tube for a long time.

[0005] Preferably, the buffer assembly includes a connecting frame, the inner side of the connecting frame is fixedly connected to the side of the fixing rod, and buffer plates are fixedly connected to both sides of the connecting frame, and a rubber block is fixedly connected to the middle of the buffer plate; when the air suction machine stops working, the contact frame is stretched by the reset of the fourth spring, so that the contact frame moves toward the connecting frame, and thus by arranging a rubber block on the buffer plate, when the fourth spring drives the contact frame to move toward the connecting frame, it is avoided that the impact force between the contact frame and the connecting frame is too large, which may cause damage to the side of the contact frame, and at the same time, when the contact frame contacts and collides with the rubber block, the smoke and dust impurities scraped off the scraper can be shaken off by the vibration generated by the collision, thereby avoiding smoke and dust impurities remaining on the scraper after the scraper cleans the inner side of the filter tube.

[0006] The beneficial effects of the present invention are as follows: 1. The present invention provides a clamping mechanism. When the plastic workpiece contacts and is polished by the polishing component, the plastic workpiece is easily deformed, which causes polishing deviation in the polishing of the plastic workpiece. When the plastic workpiece needs to be clamped, since the rod of the electric vehicle speed control handle is mostly hollow, the three clamping blocks are supported and abutted against the inner wall of the plastic workpiece. The clamping blocks are driven by the stretching of the first spring so that the clamping blocks abut against the inner wall of the plastic workpiece. At the same time, the threaded rod is rotated so that the threaded rod drives the clamping blocks to fit closely with the inner surface of the plastic workpiece to achieve precise positioning. The inner wall of the hollow shaft is a relatively stable supporting surface, which can better fix the workpiece and reduce displacement and shaking during processing, thereby improving processing accuracy and facilitating the polishing component to polish the side of the plastic workpiece.

[0007] 2. The present invention sets a filtering mechanism, turns on the air sucker, and uses the suction force generated by the air sucker when the workpiece is grinded to suck the waste gas and waste chips generated during the grinding process into the collection box. At the same time, the air sucker continuously passes the waste gas entering the collection box into the filter tube through the through hole, so that the waste gas passes through the carbon powder box and is discharged through the air outlet plate, thereby avoiding direct discharge of the waste gas generated by the grinding process. Pollutants such as particulate matter and VOCs in the grinding waste gas will increase the concentration of pollutants in the air, resulting in a decrease in air quality.

[0008] 3. The present invention provides a buffer assembly, and the contact frame is stretched by the reset of the fourth spring, so that the contact frame moves toward the connecting frame. A rubber block is provided on the buffer plate, and when the fourth spring drives the contact frame to move toward the connecting frame, it is avoided that the impact force between the contact frame and the connecting frame is too large, which will cause damage to the side of the contact frame. At the same time, when the contact frame contacts and collides with the rubber block, the vibration generated by the collision can shake off the smoke and dust impurities scraped off the scraper, thereby avoiding the residual smoke and dust impurities on the scraper after the scraper cleans the inner side of the filter tube.

[0009] 4. The present invention sets a contact assembly, and the contact frame drives the scraper to move on the fixed rod through the give way hole, and at the same time enables the scraper to move and clean the inner wall of the filter tube. When the exhaust gas collection work is completed and the air suction machine stops working, the contact frame can be driven by the reset of the fourth spring, so that the scraper can perform secondary cleaning and scraping work on the inner side of the filter tube, thereby preventing the exhaust gas from passing through the filter tube for a long time, which will cause a large amount of smoke and dust impurities to remain on the inner side of the filter tube, thereby causing corrosion to the inner wall of the filter tube for a long time.

When the side of the workpiece needs to be clamped, the three clamping plates 257 are abutted against the side of the workpiece, and at the same time, the threaded rod 253 is screwed against the inner side of the clamping seat 251 After the thread connection, the knob 254 is continuously rotated to drive the threaded rod 253 to move on the clamping seat 251, and the threaded rod 253 drives the clamping plate 257 to clamp the side of the workpiece through the rotating shaft 259, thereby clamping the side of the workpiece. At the same time, when grinding the plastic workpiece, since the material of the plastic workpiece is relatively soft, when grinding the workpiece, if the side of the plastic workpiece is clamped, when the plastic workpiece contacts and grinds with the grinding component 3, it is easy to cause the plastic workpiece to deform, thereby causing the grinding of the plastic workpiece to cause grinding deviation. When the plastic workpiece needs to be polished, During clamping, since the rods of the electric vehicle speed regulating handlebars are mostly hollow, the three clamping blocks 258 are supported and abutted against the inner wall of the plastic workpiece. The clamping blocks 258 are driven by the stretching of the first spring 256 so that the clamping blocks 258 abut against the inner wall of the plastic workpiece.

Embodiment 2, use Figure 5-Figure 9 The rod grinding equipment for producing the electric vehicle speed regulating handle of the present invention is described as follows; like Figure 5-Figure 9It is shown that a rod grinding device for manufacturing an electric vehicle speed regulating handlebar of the present invention is based on the first embodiment; The collecting component 4 includes a collecting box 41, the side of which is fixedly connected to the inner side of the machine body 1, a mesh plate 42 is fixedly connected to the top of the collecting box 41, a collecting plate 43 is fixedly connected to the inner side of the collecting box 41, a telescopic rod 45 is fixedly connected to the bottom of the mesh plate 42, a square frame 44 is fixedly connected to the bottom of the telescopic rod 45, a second spring 46 is sleeved on the telescopic rod 45, one end of the second spring 46 is fixedly connected to the mesh plate 42, the other end of the second spring 46 is fixedly connected to the square frame 44, an ejection mechanism 47 is fixedly connected to the square frame 44, the ejection mechanism 47 is concentrically arranged with the mesh of the mesh plate 42, and a filtering mechanism 48 is fixedly connected to the inner side of the collecting box 41; when the workpiece is being polished, the filtering mechanism 48 is opened, and the suction force generated by the filtering mechanism 48 when working is used to remove the waste gas and waste chips generated during polishing through the mesh plate 4 2 is sucked into the collection box 41 for collection, and the waste chips fall onto the collection plate 43, so as to facilitate the subsequent recycling of the waste chips. At the same time, when the waste chips enter the collection box 41 through the mesh plate 42, the suction force generated by the filter mechanism 48 when working causes the square frame 44 to move downward through the telescopic rod 45, so that the square frame 44 drives the ejection mechanism 47 to separate from the mesh holes of the mesh plate 42. When the collection work is completed and the filter mechanism 48 stops working, the square frame 44 is reset by the stretching of the second spring 46, so that the square frame 44 drives the ejection mechanism 47 to move toward the mesh holes of the mesh plate 42, so that the ejection mechanism 47 ejects the waste chips blocked at the mesh holes of the mesh plate 42, so as to avoid that when the waste chips enter the collection box 41 through the mesh plate 42, part of the waste chips will be stuck at the mesh holes of the mesh plate 42, and thus it is difficult to fall naturally; The ejection mechanism 47 includes an ejection rod 471, the bottom of the ejection rod 471 is fixedly connected to the top of the square frame 44, a notch 472 is provided on the side of the ejection rod 471, a slider 473 is slidably connected to the inner side of the notch 472, a connecting shaft 474 is fixedly connected to the side of the slider 473, a top of the connecting shaft 474 is fixedly connected to an ejector pin 475, a third spring 476 is sleeved on the connecting shaft 474, the top of the third spring 476 is fixedly connected to the bottom of the ejector pin 475, and the bottom of the third spring 476 is fixedly connected to the top of the ejection rod 471; when the filtering mechanism 48 stops working, the square frame 44 is released by the second spring 46 The stretching and resetting drive the ejector rod 471 to move toward the mesh of the mesh plate 42, so that the ejector rod 471 drives the ejector pin 475 to eject the waste chips stuck in the mesh. At the same time, when the squeezing force between the ejector pin 475 and the waste chips stuck in the mesh is greater than the stretching force of the third spring 476, the slider 473 drives the ejector pin 475 to move in the slot 472 through the connecting shaft 474, so as to avoid excessive squeezing force between the ejector pin 475 and the waste chips stuck in the mesh of the mesh plate 42, which will cause squeezing damage to the ejector pin 475, and at the same time, cause friction damage to the inner side of the mesh of the mesh plate 42, thereby causing the mesh aperture to become larger. The filter mechanism 48 includes a filter tube 481, the side of the filter tube 481 is fixedly connected to the inner side of the collection box 41, the side of the filter tube 481 is evenly provided with through holes 482, both ends of the filter tube 481 are fixedly connected to an air outlet plate 483, the side of the air outlet plate 483 is fixedly connected to an air suction machine 484, the side of the air suction machine 484 away from the air outlet plate 483 is fixedly connected to a carbon powder box 485, both sides of the inner wall of the filter tube 481 are fixedly connected to a fixing frame 486, a fixing rod 4810 is fixedly connected to the fixing frame 486, a buffer assembly 487 is fixedly connected to the middle of the fixing rod 4810, and the fixing frame 486 One end away from the suction machine 484 is fixedly connected to a fourth spring 488, and the other end of the fourth spring 488 is fixedly connected to a contact assembly 489; by turning on the suction machine 484, the exhaust gas and waste chips generated during the grinding of the workpiece are sucked into the collection box 41 through the suction force generated by the suction machine 484 when it is working, and at the same time, the exhaust gas entering the collection box 41 is continuously passed through the through hole 482 into the filter tube 481 through the suction machine 484, so that the exhaust gas passes through the carbon powder box 485 and the air outlet plate 483 to be discharged, thereby avoiding the direct discharge of the exhaust gas generated by the grinding process, and the particulate matter and VOCs in the grinding exhaust gas. The pollutants such as the above will increase the concentration of pollutants in the air, resulting in a decrease in air quality. At the same time, the suction force generated by the air suction machine 484 when working causes the contact component 489 to move on the fixed rod 4810, and at the same time, the contact component 489 can move and clean the inner wall of the filter tube 481. At the same time, when the contact component 489 is reset by the movement of the fourth spring 488, the contact component 489 contacts and collides with the buffer component 487, so that the contact component 489 can be buffered.

The contact frame 4891 moves on the fixed rod 4810, and at the same time enables the scraper 4893 to move and clean the inner wall of the filter tube 481. When the exhaust gas collection work is completed and the suction machine 484 stops working, the contact frame 4891 can be driven by the reset of the fourth spring 488, so that the scraper 4893 can perform secondary cleaning and scraping work on the inner side of the filter tube 481, thereby preventing the exhaust gas from passing through the filter tube 481 for a long time, which will cause a large amount of smoke and dust impurities to remain on the inner side of the filter tube 481, thereby causing corrosion to the inner wall of the filter tube 481 for a long time.

[0013] The buffer assembly 487 includes a connecting frame 4871, the inner side of which is fixedly connected to the side of the fixing rod 4810, and the two sides of the connecting frame 4871 are fixedly connected to the buffer plates 4872, and the middle of the buffer plates 4872 is fixedly connected to the rubber block 4873; when the suction machine 484 stops working, the contact frame 4891 is stretched by the reset of the fourth spring 488, so that the contact frame 4891 moves toward the connecting frame 4871, thereby providing the rubber block 4873 on the buffer plate 4872, When the fourth spring 488 drives the contact frame 4891 to move toward the connecting frame 4871, it prevents the impact force between the contact frame 4891 and the connecting frame 4871 from being too large, thereby causing damage to the side of the contact frame 4891. At the same time, when the contact frame 4891 contacts and collides with the rubber block 4873, the vibration generated by the collision can shake off the smoke and dust impurities scraped off the scraper 4893, thereby preventing the scraper 4893 from remaining smoke and dust impurities after cleaning the inner side of the filter tube 481 by the scraper 4893. The specific workflow is as follows: During operation, the workpiece is placed in the moving part 2 for clamping and rotation, so that the grinding part 3 grinds the workpiece, and at the same time, the collecting part 4 is opened to collect the waste gas and waste chips generated during the grinding process; By clamping the workpiece on the clamping mechanism 25, turning on the first motor 22, and driving the screw rod 21 to rotate inside the machine body 1 through the output end of the first motor 22, thereby driving the moving frame 23 to move inside the machine body 1, and then performing appropriate adjustment work according to different lengths of the workpiece, after the workpiece is clamped, turning on the second motor 24, and driving the clamping mechanism 25 to rotate through the output end of the second motor 24, so that the grinding component 3 grinds the workpiece on the clamping mechanism 25; When clamping and fixing the workpiece, since the workpieces are of different sizes and have different material hardnesses, the side of the workpiece or the inner side of the workpiece is selected to be clamped according to the size of the workpiece and the hardness of the material. When it is necessary to clamp the side of the workpiece, the three clamping plates 257 are used to abut against the side of the workpiece, and at the same time, the threaded rod 253 is threadedly connected to the inner side of the clamping seat 251, and the knob 254 is continuously rotated to drive the threaded rod 253 to move on the clamping seat 251. At the same time, the threaded rod 253 drives the clamping plate 257 to clamp the side of the workpiece through the rotating shaft 259, thereby clamping the side of the workpiece. At the same time, when grinding the plastic workpiece, since the material of the plastic workpiece is relatively soft, when grinding the workpiece, if the side of the plastic workpiece is clamped, When the plastic workpiece is in contact with the grinding component 3 for grinding, the plastic workpiece is easily deformed, which causes grinding deviation in the grinding of the plastic workpiece. When the plastic workpiece needs to be clamped, since the rods of the electric vehicle speed control handle are mostly hollow, the three clamping blocks 258 are supported and abutted against the inner wall of the plastic workpiece. The clamping blocks 258 are driven by the stretching of the first spring 256 so that the clamping blocks 258 abut against the inner wall of the plastic workpiece. At the same time, by rotating the threaded rod 253, the threaded rod 253 drives the clamping blocks 258 to fit closely with the inner surface of the plastic workpiece to achieve precise positioning. The inner wall of the hollow shaft is a relatively stable supporting surface, which can better fix the workpiece and reduce displacement and shaking during processing, thereby improving processing accuracy and facilitating the grinding component 3 to grind the side of the plastic workpiece. When the workpiece is being polished, the filter mechanism 48 is opened, and the suction force generated by the filter mechanism 48 when working is used to suck the waste gas and waste chips generated during polishing into the collection box 41 through the mesh plate 42 for collection, and the waste chips fall onto the collection plate 43, so as to facilitate the subsequent recycling of the waste chips. At the same time, when the waste chips enter the collection box 41 through the mesh plate 42, the suction force generated by the filter mechanism 48 when working is used, and the square frame 44 moves downward through the telescopic rod 45, so that the square frame 44 can be easily cleaned. The frame 44 drives the ejection mechanism 47 to separate from the mesh holes of the mesh plate 42. When the collection work is finished and the filtering mechanism 48 stops working, the frame 44 is reset by the stretching of the second spring 46, so that the frame 44 drives the ejection mechanism 47 to move toward the mesh holes of the mesh plate 42, so that the ejection mechanism 47 ejects the waste chips blocked at the mesh holes of the mesh plate 42, thereby preventing the waste chips from being stuck at the mesh holes of the mesh plate 42 when entering the collection box 41 through the mesh plate 42, and thus being difficult to fall naturally. When the filter mechanism 48 stops working, the square frame 44 is reset by the stretching of the second spring 46, driving the ejection rod 471 to move toward the mesh of the mesh plate 42, so that the ejection rod 471 drives the ejector pin 475 to eject the waste chips stuck in the mesh. At the same time, when the squeezing force between the ejector pin 475 and the waste chips stuck in the mesh is greater than the stretching force of the third spring 476, the slider 473 drives the ejector pin 475 to move in the slot 472 through the connecting shaft 474, so as to avoid excessive squeezing force between the ejector pin 475 and the waste chips stuck in the mesh of the mesh plate 42, thereby causing squeezing damage to the ejector pin 475 and friction damage to the inner side of the mesh of the mesh plate 42, thereby causing the mesh aperture to become larger. By turning on the suction machine 484, the exhaust gas and waste chips generated during the grinding of the workpiece are sucked into the collection box 41 through the suction force generated by the suction machine 484. At the same time, the exhaust gas entering the collection box 41 is continuously passed through the through hole 482 by the suction machine 484 to enter the filter tube 481, so that the exhaust gas passes through the carbon powder box 485 and the air outlet plate 483 to be discharged, thereby avoiding the direct discharge of the exhaust gas generated by the grinding process. Pollutants such as particulate matter and VOCs in the grinding exhaust gas will increase the concentration of pollutants in the air, resulting in a decrease in air quality. At the same time, the suction force generated by the suction machine 484 when it is working makes the contact component 489 move on the fixed rod 4810, and at the same time, the contact component 489 can move and clean the inner wall of the filter tube 481. At the same time, when the contact component 489 is reset by the movement of the fourth spring 488, the contact component 489 contacts and collides with the buffer component 487, so that the contact component 489 can be buffered. When the suction machine 484 is working, the suction force generated causes the contact frame 4891 to drive the scraper 4893 to move on the fixed rod 4810 through the clearance hole 4892, and at the same time, the scraper 4893 can move and clean the inner wall of the filter tube 481. When the exhaust gas collection work is completed and the suction machine 484 stops working, the contact frame 4891 can be driven by the reset of the fourth spring 488, so that the scraper 4893 can perform a secondary cleaning and scraping work on the inner side of the filter tube 481, thereby preventing the exhaust gas from passing through the filter tube 481 for a long time, which will cause a large amount of smoke and dust impurities to remain on the inner side of the filter tube 481, thereby causing corrosion to the inner wall of the filter tube 481 for a long time; When the suction machine 484 stops working, the contact frame 4891 is re-stretched by the fourth spring 488, so that the contact frame 4891 moves toward the connecting frame 4871. Therefore, by providing a rubber block 4873 on the buffer plate 4872, the fourth spring 488 drives the contact frame 4891 to move toward the connecting frame 4871, thereby avoiding excessive impact force between the contact frame 4891 and the connecting frame 4871, which will cause damage to the side of the contact frame 4891. At the same time, when the contact frame 4891 contacts and collides with the rubber block 4873, the vibration generated by the collision can shake off the smoke and dust impurities scraped off the scraper 4893, thereby avoiding smoke and dust impurities remaining on the scraper 4893 after the scraper 4893 cleans the inner side of the filter tube 481.
