Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly relates to a wastewater purification treatment engineering device based on a magnetic separation strengthening structure. Background Art

[0002] Wastewater treatment is to separate or transform pollutants such as suspended solids, organic matter, and heavy metals in wastewater through physical, chemical, or biological methods to make the water quality meet the discharge standards. During the process of purifying wastewater, by adding special magnetic seeds to the water body, under the action of coagulants and flocculants, the magnetic seeds combine with suspended solids and pollutants to form magnetic flocs. When the wastewater flows through the magnetic cylinder, the magnetic flocs are instantaneously adsorbed onto the surface of the magnetic cylinder, carried out of the water surface as the magnetic cylinder rotates, and discharged through a slag discharging device to achieve solid-liquid separation.

[0003] Currently, during the process of purifying wastewater by magnetic separation technology, after the rotating magnetic cylinder drives the magnetic flocs to move above the water surface, a scraping bar is usually used to contact the circumferential surface of the magnetic cylinder. The rotating magnetic flocs and the stationary scraping bar generate relative motion, and under the action of mechanical force, the magnetic flocs are scraped off the surface of the magnetic cylinder. However, due to the large magnetic force between the magnetic cylinder and the magnetic flocs, the scraped magnetic flocs are easily accumulated on the side of the scraping bar close to the magnetic cylinder, making it difficult to effectively clean the magnetic flocs on the scraping bar, and thus affecting the scraping of the magnetic flocs on the magnetic cylinder by the scraping bar. Summary of the Invention

[0004] Aiming at the above-mentioned drawbacks of the prior art, the present invention provides a wastewater purification treatment engineering device based on a magnetic separation strengthening structure, which can effectively solve the problem in the prior art that due to the large magnetic force between the magnetic cylinder and the magnetic flocs, the scraped magnetic flocs are easily accumulated on the side of the scraping bar close to the magnetic cylinder, making it difficult to effectively clean the magnetic flocs on the scraping bar, and thus affecting the scraping of the magnetic flocs on the magnetic cylinder by the scraping bar.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: The present invention provides a wastewater purification treatment engineering device based on a magnetic separation strengthening structure, including: A base, on the upper surface of which a flowing water plate is fixedly connected. The base is rotationally connected with a magnetic cylinder through a bracket provided on its upper surface. The magnetic cylinder is located above the flowing water plate. The base is fixedly connected with a slag collecting plate through a first support plate provided on its upper surface. The upper surface of the base is distributively and fixedly connected with an outer plate and an inner plate. The inner plate is located between the outer plate and the magnetic cylinder, and a central groove is provided at the center of the inner plate; A central circular plate, the outer circumferential surface of the central circular plate is rotatably connected to the inner wall of the central groove. A rectangular frame is slidably arranged on one side of the inner plate close to the magnetic cylinder. A sliding rod is slidably connected to the inner wall of the rectangular frame. An arc-shaped scraping plate is fixedly connected to the outer circumferential surface of the sliding rod. A guiding folding rail is fixedly connected to the top of the inner plate. One end of the sliding rod penetrates through the guiding folding rail and is slidably connected to the guiding folding rail; Among them, during the process of the central circular plate rotating around its own axis, first, it drives the bottom end of the arc-shaped scraping plate to scrape along the circumferential surface of the magnetic cylinder, then the arc-shaped scraping plate drives the magnetic flocs scraped from the circumferential surface of the magnetic cylinder to move upward to above the slag collection area of the slag collection plate, and finally the arc-shaped scraping plate rotates a certain angle around the axis of the sliding rod so that the magnetic flocs in the arc-shaped scraping plate fall downward into the inside of the slag collection plate.

[0006] Further, a fixed folding plate is fixedly connected to the top of the slag collection plate. A telescopic plate is slidably connected to the upper surface of the fixed folding plate. A pushing folding rail is fixedly connected to one side of the telescopic plate close to the guiding folding rail. A bottom block is fixedly connected to the lower surface of the telescopic plate.

[0007] Further, a U-shaped rail is fixedly connected to one side of the inner plate close to the magnetic cylinder. Both ends of the rectangular frame are slidably connected to the inner wall of the U-shaped rail. A pushing and pulling block is fixedly connected to one side of the central circular plate close to the magnetic cylinder. A push rod is rotatably connected between the outer circumferential surface of the pushing and pulling block and the lower surface of the rectangular frame. A push block is rotatably connected to one side of the rectangular frame close to the magnetic cylinder.

[0008] Further, a fixed strip is fixedly connected to the top of the outer plate. One end of the sliding rod penetrates through the guiding folding rail and is fixedly connected to a rotating rod. A rotating block is rotatably connected to one side of the fixed strip close to the rotating rod. A rotating ring is rotatably sleeved on the outer circumferential surface of the rotating block. A clamping block is fixedly connected to the outer circumferential surface of the rotating ring. A blocking strip is fixedly connected to one side of the fixed strip close to the rotating rod.

[0009] Further, an L-shaped rod is fixedly connected to the outer circumferential surface of the rotating ring. A rotating pushing and pulling rail is fixedly connected to one side of the central circular plate close to the outer plate. One end of the L-shaped rod far from the rotating ring is slidably connected to the rotating pushing and pulling rail.

[0010] Further, the rotating pushing and pulling rail includes an arc-shaped rail and a pushing and pulling folding rail connected end to end. Both the arc-shaped rail and the pushing and pulling folding rail are fixedly connected to one side of the central circular plate close to the outer plate; Among them, during the process of the central circular plate rotating around its own axis, the central circular plate drives the arc-shaped rail and the pushing and pulling folding rail to rotate synchronously, so that the pushing and pulling folding rail and the arc-shaped rail alternately slide with one end of the L-shaped rod.

[0011] Further, the base is rotatably connected with a transmission rod through a second support plate arranged on its upper surface. A driving motor is fixedly connected to one side of the second support plate away from the transmission rod. The output end of the driving motor penetrates through the second support plate and is fixedly connected with the transmission rod. A first rotating pulley is fixedly connected to one side of the central circular plate close to the outer plate. Second rotating pulleys are fixedly connected to both ends of the magnetic cylinder. A first rotating pulley and a second rotating pulley are fixedly connected to the outer circumferential surface of the transmission rod respectively. A first belt is connected between the first rotating pulley and the first rotating pulley for transmission, and a second belt is connected between the second rotating pulley and the second rotating pulley for transmission.

[0012] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: The present invention is provided with a central circular plate. By controlling the driving motor to drive the central circular plate to rotate, the central circular plate drives the rectangular frame to move up and down reciprocally along the inner wall of the U-shaped rail through the push-pull block and the push-pull rod. The rectangular frame drives the two sliding rods to approach each other along the arc ends of the guiding folding rail. The bottoms of the two sliding rods drive the bottoms of the two arc-shaped scrapers to move along the circumferential surface of the magnetic cylinder. After the bottoms of the two arc-shaped scrapers are attached (as Figure 8 shown), the two arc-shaped scrapers scrape off the magnetic flocs adhering to the circumferential surface of the magnetic cylinder, and the scraped magnetic flocs are located between the two arc-shaped scrapers. The rectangular frame continues to move upward. The rectangular frame drives the two sliding rods to move upward along the vertical ends of the guiding folding rail. The two sliding rods drive the two arc-shaped scrapers in a closed state to move upward. The two arc-shaped scrapers drive the magnetic flocs inside them to move upward. After the magnetic flocs are separated from the magnetic cylinder by a certain distance, the rectangular frame drives the push block to slide along the pushing folding rail. The push block drives the telescopic plate to move along the upper surface of the fixed folding plate through the pushing folding rail (as Figure 9 shown), so that the telescopic plate is located below the two arc-shaped scrapers. After the rectangular frame drives the sliding rod to move to the top of the guiding folding rail, the lower sliding rod drives the rotating rod to separate from the blocking strip, releasing the rotational limit of the blocking strip on the rotating rod, the lower sliding rod and the lower arc-shaped scraper. Under the action of gravity, the lower arc-shaped scraper rotates downward around the axis of the sliding rod, and the magnetic flocs between the two arc-shaped scrapers fall downward onto the upper surface of the telescopic plate. The magnetic flocs move sequentially along the upper surfaces of the telescopic plate and the fixed folding plate into the inside of the slag collecting plate, preventing the scraped magnetic flocs from accumulating on the surfaces of the two arc-shaped scrapers, thereby effectively cleaning the magnetic flocs on the two arc-shaped scrapers, and further improving the scraping effect of the two arc-shaped scrapers on the magnetic flocs on the magnetic cylinder.

The outer plate 14 and the inner plate 15 are fixedly connected to the upper surface of the base 1 in a distributed manner. The inner plate 15 is located between the outer plate 14 and the magnetic cylinder 12, and a central groove is provided at the center of the inner plate 15; A central circular plate 2, the outer circumferential surface of the central circular plate 2 is rotatably connected to the inner wall of the central groove. A rectangular frame 21 is slidably arranged on the side of the inner plate 15 close to the magnetic cylinder 12. A sliding rod 22 is slidably connected to the inner wall of the rectangular frame 21. An arc-shaped scraping plate 23 is fixedly connected to the outer circumferential surface of the sliding rod 22. A guiding folding rail 24 is fixedly connected to the top of the inner plate 15. One end of the sliding rod 22 penetrates through the guiding folding rail 24 and is slidably connected to the guiding folding rail 24; Among them, during the process of the central circular plate 2 rotating around its own axis, first, the bottom end of the arc-shaped scraping plate 23 is driven to scrape along the circumferential surface of the magnetic cylinder 12, then the arc-shaped scraping plate 23 drives the magnetic flocs scraped from the circumferential surface of the magnetic cylinder 12 to move upward to above the slag collection area of the slag collection plate 13, and finally the arc-shaped scraping plate 23 rotates a certain angle around the axis of the sliding rod 22 so that the magnetic flocs in the arc-shaped scraping plate 23 fall downward into the interior of the slag collection plate 13.

[0019] A fixed folding plate 132 is fixedly connected to the top of the slag collection plate 13. A telescopic plate 133 is slidably connected to the upper surface of the fixed folding plate 132. A pushing folding rail 134 is fixedly connected to the side of the telescopic plate 133 close to the guiding folding rail 24. A bottom block 135 is fixedly connected to the lower surface of the telescopic plate 133.

[0020] On one side of the inner plate 15 close to the magnetic cylinder 12, a U-shaped rail 211 is fixedly connected. Both ends of the rectangular frame 21 are slidably connected to the inner wall of the U-shaped rail 211. On one side of the central circular plate 2 close to the magnetic cylinder 12, a push-pull block 212 is fixedly connected. A push-pull rod 213 is rotatably connected between the outer circumferential surface of the push-pull block 212 and the lower surface of the rectangular frame 21. On one side of the rectangular frame 21 close to the magnetic cylinder 12, a push block 214 is rotatably connected.

[0021] At the top of the outer plate 14, a fixed strip 221 is fixedly connected. One end of a slide rod 22 passes through a guiding folding rail 24 and is fixedly connected to a rotating rod 222. A rotating block 223 is rotatably connected to one side of the fixed strip 221 close to the rotating rod 222. A rotating ring 224 is rotatably sleeved on the outer circumferential surface of the rotating block 223. A clamping block 225 is fixedly connected to the outer circumferential surface of the rotating ring 224. A blocking strip 226 is fixedly connected to one side of the fixed strip 221 close to the rotating rod 222.

[0022] A connecting rod 227 is fixedly connected to the outer circumferential surface of the rotating ring 224. A rotating push-pull rail 228 is fixedly connected to one side of the central circular plate 2 close to the outer plate 14. The end of the connecting rod 227 far from the rotating ring 224 is slidably connected to the rotating push-pull rail 228.

[0023] The rotating push-pull rail 228 includes an arc-shaped rail 2281 and a push-pull folding rail 2282 connected end to end. Both the arc-shaped rail 2281 and the push-pull folding rail 2282 are fixedly connected to one side of the central circular plate 2 close to the outer plate 14; Among them, during the process of the central circular plate 2 rotating around its own axis, the central circular plate 2 drives the arc-shaped rail 2281 and the push-pull folding rail 2282 to rotate synchronously, so that the push-pull folding rail 2282 and the arc-shaped rail 2281 alternately slide-connect with one end of the connecting rod 227.

[0024] The base 1 is rotatably connected to a transmission rod 25 through a second support plate 251 arranged on its upper surface. A driving motor 252 is fixedly connected to one side of the second support plate 251 far from the transmission rod 25. The output end of the driving motor 252 passes through the second support plate 251 and is fixedly connected to the transmission rod 25. A first rotating small wheel 254 is fixedly connected to one side of the central circular plate 2 close to the outer plate 14. Second rotating large wheels 256 are fixedly connected to both ends of the magnetic cylinder 12. A first rotating large wheel 253 and a second rotating small wheel 257 are respectively fixedly connected to the outer circumferential surface of the transmission rod 25. A first belt 255 is connected for transmission between the first rotating large wheel 253 and the first rotating small wheel 254. A second belt 258 is connected for transmission between the second rotating small wheel 257 and the second rotating large wheel 256.

[0025] The rotation process of the arc-shaped scraper 23: In practical applications, by starting the drive motor 252, the drive motor 252 drives the transmission rod 25 to rotate between the two second support plates 251 through the output end. The transmission rod 25 drives the first large rotating wheel 253 on its circumferential outer surface to rotate synchronously. Under the transmission action of the first belt 255, the rotating first large rotating wheel 253 drives the first small rotating wheel 254 to rotate around the axis of the central circular plate 2 through the first belt 255. The first small rotating wheel 254 drives the central circular plate 2 to rotate on its own axis at the center of the inner plate 15. The central circular plate 2 drives the rotating push-pull rail 228 on its outer surface to rotate synchronously, so that one end of the L-shaped rod 227 far from the rotating ring 224 slides along the push-pull folding rail 2282. Under the pushing action of the push-pull folding rail 2282, the push-pull folding rail 2282 pushes one end of the L-shaped rod 227 to rotate upward around the axis of the rotating ring 224. The L-shaped rod 227 drives the rotating ring 224 to rotate around the axis of the rotating block 223. The rotating ring 224 drives the clamping blocks 225 on its circumferential outer surface to rotate upward. The two upward-rotating clamping blocks 225 push the lower sliding rod 22 to rotate around its own axis through the rotating rod 222. The lower sliding rod 22 drives the lower arc-shaped scraping plate 23 to rotate upward around the axis of the sliding rod 22. Under the rotating action of the central circular plate 2, after the L-shaped rod 227 is slidably connected to the arc-shaped rail 2281 along the push-pull folding rail 2282, at this time, the lower arc-shaped scraping plate 23 rotates around the axis of the sliding rod 22 by a certain angle and contacts the circumferential surface of the magnetic cylinder 12 (as Figure 7 shown), and under the limiting action of the arc-shaped rail 2281, the positions of the rotating ring 224 and the clamping blocks 225 are fixed. The clamping blocks 225 limit the rotation angles of the lower sliding rod 22 and the arc-shaped scraping plate 23 through the rotating rod 222, so that the bottom end of the arc-shaped scraping plate 23 always remains in contact with the circumferential surface of the magnetic cylinder 12; The process of scraping off magnetic flocs: In practical applications, the rotating central circular plate 2 drives the push-pull block 212 on one side of it to rotate around the axis of the magnetic cylinder 12. Under the limiting action of the U-shaped rail 211, the rotating push-pull block 212 drives the rectangular frame 21 to move upward along the inner wall of the U-shaped rail 211 through the push-pull rod 213 on its circumferential outer surface. Under the guiding action of the guiding folding rail 24, the upward-moving rectangular frame 21 drives the two sliding rods 22 inside it to approach each other along the arc-shaped ends of the guiding folding rail 24 (the upper sliding rod 22 slides downward along the arc-shaped end of the guiding folding rail 24, and the lower sliding rod 22 slides upward along the arc-shaped end of the guiding folding rail 24). The lower sliding rod 22 drives the two rotating rods 222 at its two ends to move upward along the arc-shaped ends of the guiding folding rail 24, so that the rotating rods 222 are in contact with the clamping blocks 225 and the stop bars 226 in sequence (as Figure 7 and Figure 8As shown, under the action of gravity, the lower arc-shaped scraper 23 is prone to rotate downward around the axis of the sliding rod 22 and separate from the circumferential surface of the magnetic cylinder 12. However, under the blocking action of the clamping block 225 and the blocking strip 226 on the rotating rod 222, the rotation angle of the sliding rod 22 and the arc-shaped scraper 23 is limited to prevent the arc-shaped scraper 23 from rotating downward around the axis of the rotating rod 222, so as to ensure that the bottom end of the arc-shaped scraper 23 always remains in contact with the circumferential surface of the magnetic cylinder 12. The two mutually approaching sliding rods 22 drive the bottom ends of the two arc-shaped scrapers 23 to move along the circumferential surface of the magnetic cylinder 12. After the bottom ends of the two arc-shaped scrapers 23 are fitted together (as Figure 8 shown), the two arc-shaped scrapers 23 scrape off the magnetic flocs adhering to the circumferential surface of the magnetic cylinder 12 and make the scraped magnetic flocs located between the two arc-shaped scrapers 23; Material transfer process of magnetic flocs: In practical applications, the rectangular frame 21 continues to move upward along the inner wall of the U-shaped rail 211. Under the guiding action of the guiding folding rail 24, the upward-moving rectangular frame 21 continues to drive the two sliding rods 22 inside it to move upward along the vertical end of the guiding folding rail 24 (as Figure 8 shown). The two sliding rods 22 drive the two arc-shaped scrapers 23 in a closed state to perform an "oblique upward movement" along the vertical end of the guiding folding rail 24. The two arc-shaped scrapers 23 drive the magnetic flocs inside them to perform an "oblique upward movement" synchronously. After the two arc-shaped scrapers 23 drive the magnetic flocs to separate from the magnetic cylinder 12 by a certain distance, the two upward-moving rectangular frames 21 drive the push blocks 214 on one side of them to enter the inside of the pushing folding rail 134 along the open end of the pushing folding rail 134. After the two push blocks 214 slide upward along the pushing folding rail 134 by a certain distance, the two push blocks 214 drive the telescopic plate 133 to perform an "oblique upward movement" along the upper surface of the fixed folding plate 132 through the pushing folding rail 134 (as Figure 9 shown), so that the telescopic plate 133 is located below the two arc-shaped scrapers 23. After the upward-moving rectangular frame 21 drives the two sliding rods 22 to move to the top end of the guiding folding rail 24, the lower sliding rod 22 drives the rotating rods 222 at both ends of it to separate from the blocking strip 226, releasing the rotational limit of the blocking strip 226 on the rotating rod 222, the lower sliding rod 22 and the lower arc-shaped scraper 23. Under the action of gravity, the lower arc-shaped scraper 23 automatically rotates downward around the axis of the sliding rod 22, so that the two arc-shaped scrapers 23 are in a separated state (as Figure 9 shown). The magnetic flocs between the two arc-shaped scrapers 23 fall downward onto the upper surface of the telescopic plate 133, and the magnetic flocs sequentially perform an "oblique downward movement to the inside of the slag collecting plate 13" along the upper surfaces of the telescopic plate 133 and the fixed folding plate 132, completing the collection and treatment of the magnetic flocs; Reset process of the arc-shaped scraper 23: In practical applications, under the limiting action of the U-shaped rail 211, the rotating push-pull block 212 drives the rectangular frame 21 to move downward along the inner wall of the U-shaped rail 211 above the inner wall of the U-shaped rail 211 through the push-pull rod 213. Under the guiding action of the guiding folding rail 24, the downward-moving rectangular frame 21 drives the two sliding rods 22 inside it to move downward along the vertical end of the guiding folding rail 24. The two sliding rods 22 drive the two arc-shaped scraping plates 23 to perform an "inclined downward movement" along the vertical end of the guiding folding rail 24. Driven by the rectangular frame 21, the two sliding rods 22 perform an "opposite movement" along the arc-shaped end of the guiding folding rail 24, so as to reset the two arc-shaped scraping plates 23, facilitating the collection of magnetic flocs on the circumferential surface of the magnetic cylinder 12 in multiple cycles.

[0026] Rotation process of the magnetic cylinder 12: In practical applications, during the rotation of the transmission rod 25 between the two second support plates 251, the rotating transmission rod 25 drives the second rotating small wheel 257 on its circumferential outer surface to rotate synchronously. Under the transmission action of the second belt 258, the rotating second rotating small wheel 257 drives the second rotating large wheel 256 to rotate around the axis of the magnetic cylinder 12 through the second belt 258. The second rotating large wheel 256 drives the magnetic cylinder 12 to rotate around its own axis. Under the differential speed action of the second rotating large wheel 256 and the second rotating small wheel 257, the rotation speed of the magnetic cylinder 12 is less than the rotation speed of the transmission rod 25. Under the differential speed action of the first rotating large wheel 253 and the first rotating small wheel 254, the rotation speed of the transmission rod 25 is less than the rotation speed of the central circular plate 2. Furthermore, the rotation speed of the magnetic cylinder 12 is much less than the rotation speed of the central circular plate 2. The two arc-shaped scraping plates 23 clean the magnetic flocs on the circumferential surface of the magnetic cylinder 12 once, and the magnetic cylinder 12 rotates around its own axis by a certain angle, so as to ensure that the two arc-shaped scraping plates 23 are located on one side of the magnetic cylinder 12 to comprehensively clean the circumferential surface of the magnetic cylinder 12.

[0027] In summary, by adopting the central circular plate 2, the present application has the following advantages: Advantage one, by setting the central circular plate 2 to rotate around its own axis, the central circular plate 2 drives the rectangular frame 21 to perform an "up and down reciprocating movement" along the inner wall of the U-shaped rail 211 through the push-pull block 212 and the push-pull rod 213. During the upward movement of the rectangular frame 21, under the guiding action of the guiding folding rail 24, the rectangular frame 21 drives the two sliding rods 22 to approach each other along the arc-shaped end of the guiding folding rail 24. The two sliding rods 22 that approach each other drive the bottom ends of the two arc-shaped scraping plates 23 to move along the circumferential surface of the magnetic cylinder 12. After the bottom ends of the two arc-shaped scraping plates 23 are attached (such as Figure 8As shown in the figure, two arc-shaped scraping plates 23 scrape off the magnetic flocs adhering to the circumferential surface of the magnetic cylinder 12, and the scraped magnetic flocs are located between the two arc-shaped scraping plates 23. The rectangular frame 21 continues to move upward. Under the guiding action of the guiding folding track 24, the rectangular frame 21 continues to drive the two sliding rods 22 to move upward along the vertical end of the guiding folding track 24. The two sliding rods 22 drive the two arc-shaped scraping plates 23 in a closed state to move upward along the vertical end of the guiding folding track 24. The two arc-shaped scraping plates 23 drive the magnetic flocs inside them to move upward, so that the scraped magnetic flocs are separated from the magnetic cylinder 12 by a certain distance.

[0028] Advantage two: After the magnetic flocs are separated from the magnetic cylinder 12 by a certain distance, the rectangular frame 21 drives the push block 214 to slide along the pushing folding track 134. The push block 214 drives the telescopic plate 133 to move along the upper surface of the fixed folding plate 132 through the pushing folding track 134 (as Figure 9 shown in the figure), so that the telescopic plate 133 is located below the two arc-shaped scraping plates 23. After the rectangular frame 21 drives the sliding rod 22 to move to the top of the guiding folding track 24, the lower sliding rod 22 drives the rotating rod 222 to separate from the blocking strip 226, releasing the rotational limit of the blocking strip 226 on the rotating rod 222, the lower sliding rod 22 and the lower arc-shaped scraping plate 23. Under the action of gravity, the lower arc-shaped scraping plate 23 automatically rotates downward around the axis of the sliding rod 22, and the magnetic flocs between the two arc-shaped scraping plates 23 fall downward onto the upper surface of the telescopic plate 133. The magnetic flocs move along the upper surfaces of the telescopic plate 133 and the fixed folding plate 132 in sequence and enter the inside of the slag collecting plate 13, completing the collection and treatment of the magnetic flocs.

[0029] Advantage three: By setting the first large rotating wheel 253, the first small rotating wheel 254, the second large rotating wheel 256 and the second small rotating wheel 257, the rotation speed of the magnetic cylinder 12 is much smaller than the rotation speed of the central circular plate 2. The two arc-shaped scraping plates 23 clean the magnetic flocs on the circumferential surface of the magnetic cylinder 12 once, and the magnetic cylinder 12 rotates by a certain angle around its own axis, so as to ensure that the two arc-shaped scraping plates 23 are located on one side of the magnetic cylinder 12 to comprehensively clean the circumferential surface of the magnetic cylinder 12.

[0030] Advantage four: By setting the rotating push-pull track 228, when the central circular plate 2 rotates one week, the rotating push-pull track 228 first pushes the L rod 227 to rotate by a certain angle around the axis of the rotating ring 224 upward, and then pulls the L rod 227 to rotate by a certain angle around the axis of the rotating ring 224 downward, ensuring that after the clamping block 225 pushes the rotating rod 222 to rotate by a certain angle, the clamping block 225 can automatically reset, which is convenient for the clamping block 225 to cooperate with the reset of the rotating rod 222 to push the rotating rod 222 back and forth multiple times.
