Description

Technical Field

[0001] The invention relates to the technical field of mulch film recycling machines, and in particular to a farmland mulch film recycling machine capable of effectively separating mulch stubble. Background Art

[0002] Ground film has the functions of increasing ground temperature, inhibiting surface water evaporation, inhibiting weeds, inhibiting salt and protecting seedlings, increasing the uniformity of crop canopy illumination and increasing scattered light. It has become the fourth most important material for agricultural production after seeds, fertilizers and pesticides. The application of ground film covering technology has also significantly improved agricultural productivity. However, its material is polyethylene (PE). While the ground film covering the field effectively promotes crop growth, if it is not cleaned up in time, the PE ground film will remain in the soil and will be difficult to degrade, which will cause pollution and damage to the soil, which is not conducive to maintaining soil structure and the growth of later crops. Therefore, the ground film needs to be recycled, and the ground film recycling machine is a mechanical equipment specially used to recycle the residual ground film in farmland.

[0003] When using a mulch film recycling machine to recycle mulch film, the rolled up mulch film often carries a large amount of soil, root stubble, stones and other impurities, resulting in a large amount of debris between the mulch rolls that are finally rolled up, affecting recycling and use. Therefore, we have proposed a farmland mulch film recycling machine that can effectively separate the mulch stubble. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a farmland mulch film recycling machine that can effectively separate the film stubble, comprising:

[0005] A recycling shell, wherein a circular door is provided on one side of the recycling shell;

[0006] A traction rod, which is used to traction and dock with the tensile machine to drive the entire mulch recycling machine to move;

[0007] A circular blade disc, which is used to cut and separate the mulch film from the soil;

[0008] A square penetration rod, wherein a film scraping plate is arranged on the outer side of the square penetration rod;

[0009] A winding roller, one end of which is provided with a driving motor;

[0010] Linked rollers, both ends of which are provided with side support plates;

[0011] The stubble removal device is used to scrape and clean the soil, root stubble and stones attached to the ground film, so as to prevent the ground film being rolled up for recycling from often carrying a large amount of soil, root stubble, stones and other impurities, resulting in a large amount of debris being mixed between the film rolls that are finally rolled up and affecting recycling;

[0012] A pressing device is used to flexibly press the ground film on the surface of the linkage roller to prevent the ground film in rolling contact with the linkage roller from folding and deviating in all directions, which may easily lead to film breakage due to uneven force;

[0013] One side of the recovery shell is rotatably connected to one side of the circular door through a hinge, one side of the recovery shell is fixedly connected to one end of the traction rod, one side of the recovery shell is fixedly connected to one side of the circular cutter disc through a connecting rod, one end of the square penetration rod penetrates the recovery shell and is fixedly connected to the recovery shell, the film shoveling plate is sleeved on the square penetration rod and fixedly connected to the square penetration rod, the inner wall of the recovery shell is rotatably connected to one end of the winding roller through a rotating bolt, one end of the winding roller away from the circular door is fixedly connected to the driving shaft of the driving motor, the output end of the driving motor is fixedly connected to one side of the recovery shell, the outer surface of the recovery shell is fixedly connected to the side support plate through a connecting rod, the outer surface of the recovery shell is fixedly connected to one end of the stubble removing device, the top of the side support plate is fixedly connected to the bottom of the pressing device, and one side of the side support plate is rotatably connected to one end of the linkage roller through a rotating bolt;

[0014] Wherein, the stubble removing device comprises:

[0015] The V-shaped scraper is used to scrape and clean the soil, root stubble and stones attached to the ground film. The V-shaped scraper scrapes and cleans the soil, root stubble and stones attached to the recycled ground film to prevent the rolled-up ground film from often carrying a large amount of soil, root stubble, stones and other impurities, resulting in a large amount of debris between the film rolls that are finally rolled up, affecting recycling;

[0016] The outer surface of the recovery shell is provided with an arc-shaped through hole, and the outer surface of the winding roller is fixedly connected with a recovery ground film;

[0017] One side of the V-shaped scraper is rotatably connected to an adjusting mechanism through a rotating bolt. A V-shaped plastic pad is fixedly connected to the outer side of the V-shaped scraper. By arranging the V-shaped plastic pad on the outer side of the V-shaped scraper, it can elastically resist a large amount of lifted soil and stones, preventing the outer side of the V-shaped scraper from being gradually damaged due to long-term impact and friction by soil and stones and becoming difficult to use. One side of the V-shaped scraper close to the adjusting mechanism is fixedly connected with a first curved plate. An electric push rod I is fixedly connected to the inner side of the first curved plate. The driving shaft of the electric push rod I is fixedly connected with a V-shaped thin plate. When the V-shaped thin plate moves towards the adjusting mechanism, it scrapes and discharges sundries such as soil and stones accumulated inside the V-shaped scraper, preventing excessive flying soil and stones from continuously accumulating inside the V-shaped scraper after long-term use, making it difficult to handle and causing the recycled plastic film to be depressed under pressure and difficult to contact the V-shaped scraper. Sieve stubble round holes are formed on the outer surface of the V-shaped thin plate. By arranging a plurality of sieve stubble round holes on the surface of the V-shaped thin plate, it can strip and sieve thin strip-shaped sundries such as root stubbles on the recycled plastic film, preventing thin strip-shaped sundries such as root stubbles punctured on the recycled plastic film from being difficult to scrape off by the V-shaped scraper at one time and affecting the subsequent winding of the recycled plastic film;

[0018] One end of the adjusting mechanism away from the V-shaped scraper is fixedly connected to the outer surface of the recycling housing. The V-shaped scraper is arranged between the outer surface of the recycling housing and the recycled plastic film;

[0019] The outer side of the V-shaped thin plate is aligned with the inner side of the V-shaped scraper. A plurality of the sieve stubble round holes are provided, and the plurality of sieve stubble round holes are distributed on the V-shaped thin plate.

[0020] Further, the adjusting mechanism includes a cross-round block. One side of the cross-round block is fixedly connected with a threaded rod. The outer surface of the threaded rod is sleeved and threadedly connected with an internal-threaded cylinder. By twisting the cross-round block to drive the threaded rod and the internal-threaded cylinder to be threadedly engaged, the distance between the V-shaped scraper and the inner side of the recycled plastic film is adjusted, preventing the sundries such as soil and stones attached to the inner side of the recycled plastic film from being difficult to be scraped clean when the recycled plastic film is not in tight contact with the side of the V-shaped scraper due to different tensile forces and other factors. The bottom of the internal-threaded cylinder is fixedly connected with a corrugated ring piece. By arranging a corrugated ring piece that cooperates with the threaded rod to stretch or contract on the outside of the threaded rod, the outside of the threaded rod is wrapped and covered, preventing a large amount of soil and stones from flying and adhering to the surface of the threaded rod when inside the recycled plastic film, which affects the threaded engagement between the threaded rod and the internal-threaded cylinder. One side of the corrugated ring piece away from the internal-threaded cylinder is fixedly connected with a docking ring block. By the rotational connection between the docking ring block and the cross-round block, the corrugated ring piece is driven to stretch or contract, preventing the docking ring block from not only driving the corrugated ring piece to stretch or contract but also twisting it to cause a certain degree of damage when rotating with the cross-round block. One side of the cross-round block close to the threaded rod is fixedly connected with a vertical vertical rod. The outer surface of the vertical vertical rod is fixedly connected with a side brush. When the side brush rotates with the vertical vertical rod, it frictionally sweeps the outer surface of the corrugated ring piece, preventing sundries such as soil from gradually accumulating in the corrugated depressions on the surface of the corrugated ring piece after long-term use, which affects its telescopic effect. One end of the internal-threaded cylinder away from the corrugated ring piece is fixedly connected with the outer surface of the recycling housing. One side of the cross-round block away from the threaded rod and one side of the V-shaped scraper are rotationally connected by a rotating bolt. One side of the docking ring block away from the corrugated ring piece and one side of the cross-round block are rotationally connected by a bearing. A plurality of vertical vertical rods are provided, and the plurality of vertical vertical rods are distributed on one side of the cross-round block.

[0021] Furthermore, the pressing and attaching device includes a second curved plate, the inner side of which is fixedly connected to an electric push rod 2, the driving shaft of the electric push rod 2 is fixedly connected to a square pressing plate, and the side of the square pressing plate away from the electric push rod 2 is fixedly connected to a square sponge pad, and a flexible square sponge pad is arranged between the square pressing plate and the recovered ground film to press and attach the recovered ground film, so as to prevent the ground film that is in rolling contact with the linkage roller from folding, deviating and breaking due to uneven force, and a top-opened circular groove is provided on the top of the square sponge pad, and a circular gasket is fixedly connected to the bottom of the inner wall of the top-opened circular groove, and an elastic spacing is provided between the square sponge pad and the thin penetration rod to prevent the thin penetration rod from directly contacting the square sponge pad. The hard pressure exerted on the recovered ground film is large, which is easy to damage the recovered ground film. A return spring is fixedly connected to the top of the circular gasket, and the return spring that loses pressure drives the square sponge pad to expand and recover through the stretching force, so as to prevent the square sponge pad from gradually losing its elastic restoring force after being compressed for a long time and becoming difficult to use during expansion and recovery. A thin through rod is fixedly connected to the top of the circular gasket, and the square sponge pad is fixed and limited by arranging a thin through rod that passes through the square pressure plate on the circular gasket to prevent the square sponge pad that is in rolling contact with the recycled ground film from being twisted and deformed due to the thrust, resulting in poor pressing effect. The bottom of the second curved plate is fixedly connected to the top of the side support plate, and a plurality of the top open circular grooves are provided, and the plurality of the top open circular grooves are distributed on the top of the square sponge pad, and the outer side of the return spring is fixedly connected to the inner wall of the top open circular groove, and the top of the thin through rod passes through the square pressure plate and is slidably connected to the square pressure plate.

[0022] The present invention has the beneficial effects:

[0023] 1. The present invention uses a V-shaped scraper to scrape and clean the soil, root stubble, and stones attached to the recycled ground film, so as to prevent the rolled-up recycled ground film from often carrying a large amount of soil, root stubble, stones and other impurities, resulting in a large amount of debris mixed between the film rolls finally rolled into a roll, affecting recycling and use; the cross round block is driven by the threaded rod and the threaded cooperation of the internal threaded cylinder to adjust the distance between the V-shaped scraper and the inner side of the recycled ground film, so as to prevent the recycled ground film from being difficult to scrape off when it is not in tight contact with the side of the V-shaped scraper due to factors such as different tensile forces; a flexible square sponge pad is arranged between the square pressing plate and the recycled ground film to press the recycled ground film, so as to prevent the ground film in rolling contact with the linkage roller from folding, deviating and breaking due to uneven force.

[0024] 2. The present invention provides a stubble removal device, and the V-shaped scraper scrapes and cleans the soil, stubble and stones attached to the recycled mulch film, so as to prevent the rolled-up mulch film from often carrying a large amount of impurities such as soil, stubble and stones, resulting in a large amount of debris being mixed between the film rolls finally rolled into a roll, affecting the recycling and use. A V-shaped plastic pad is provided on the outer side of the V-shaped scraper to elastically resist the large amount of soil and stones lifted up, so as to prevent the outer side of the V-shaped scraper from being damaged by friction caused by the impact of soil and stones for a long time and gradually being damaged and difficult to use. When the V-shaped thin plate moves toward the adjustment mechanism, the soil, stones and other debris accumulated on the inner side of the V-shaped scraper are scraped and discharged, preventing the V-shaped scraper from being continuously accumulated with excessive splashing soil and stones on the inner side after long-term use, which is difficult to handle. The recovered mulch film is pressed and depressed and difficult to contact with the V-shaped scraper. By opening a plurality of screening circular holes on the surface of the V-shaped thin plate, the root stubble and other thin strips of debris on the recovered mulch film are stripped and screened, preventing the root stubble and other thin strips of debris pierced on the recovered mulch film from being difficult to be scraped away by the V-shaped scraper at one time, affecting the subsequent winding of the recovered mulch film.

[0025] 3. The present invention provides an adjusting mechanism, and the distance between the V-shaped scraper and the inner side of the recycled ground film is adjusted by twisting the cross round block to drive the threaded cooperation of the threaded rod and the internal threaded barrel, so as to prevent the recycled ground film from being difficult to scrape away when it is not in tight contact with the side of the V-shaped scraper due to factors such as different tensile forces. By providing a corrugated ring sheet that cooperates with the extension or contraction, the outer side of the threaded rod is wrapped and covered, so as to prevent a large amount of dirt and stones from flying and adhering to the surface of the threaded rod when it is on the inner side of the recycled ground film, affecting the thread cooperation between the threaded rod and the internal threaded barrel, and driving the corrugated ring sheet to extend or contract through the rotation connection between the docking ring block and the cross round block, so as to prevent the docking ring block from not only driving the corrugated ring sheet to extend or contract but also causing it to twist and cause a certain degree of damage when rotating with the cross round block. The side brush rubs and cleans the outer surface of the corrugated ring sheet as the vertical rod rotates, so as to prevent the corrugated depression on the surface of the corrugated ring sheet from gradually accumulating dirt and other debris after long-term use, affecting its telescopic effect.

[0026] 4. The present invention prevents the recycled plastic film from folding and shifting randomly and being prone to film breakage when the stress on the plastic film in rolling contact with the linkage roller is uneven by setting a pressing device and arranging a flexible square sponge pad between the square pressing plate and the recycled plastic film. The square sponge pad in rolling contact with the recycled plastic film is fixed and limited by arranging a thin through rod penetrating the square pressing plate on the circular gasket, preventing the square sponge pad from being distorted and deformed under the influence of the thrust force, resulting in poor pressing effect. An elastic interval is set between the square sponge pad and the thin through rod by arranging a circular gasket, preventing the hard pressure exerted on the recycled plastic film when the thin through rod directly contacts the square sponge pad from being too large and easily damaging the recycled plastic film. The reset spring without pressure drives the square sponge pad to expand and recover through the stretching force, preventing the square sponge pad from gradually losing its elastic recovery force after being compressed for a long time and being difficult to expand and recover, affecting the use.

[0048] The V-shaped scraping plate 111 is used for scraping and cleaning the soil, root stubbles, and stones attached to the plastic film;

[0049] An arc-shaped through hole 13 is formed on the outer surface of the recycling housing 1, and a recycled plastic film 14 is fixedly connected to the outer surface of the winding roller 7;

[0050] One side of the V-shaped scraping plate 111 is rotatably connected to the adjusting mechanism 112 through a rotating bolt. A V-shaped plastic pad 113 is fixedly connected to the outside of the V-shaped scraping plate 111. A first curved plate 114 is fixedly connected to the side of the V-shaped scraping plate 111 close to the adjusting mechanism 112. An electric push rod 115 is fixedly connected to the inner side of the first curved plate 114. A V-shaped thin plate 116 is fixedly connected to the drive shaft of the electric push rod 115.

When the inner side of the recycled plastic film 14 is not in tight contact with the side of the V-shaped scraping plate 111, the distance between the V-shaped scraping plate 111 and the inner side of the recycled plastic film 14 is adjusted by the adjusting mechanism 112.

[0053] For the second embodiment, please refer to Figures 1 - 8, the present invention provides a farmland plastic film recycling machine capable of effectively separating film stubbles: The adjusting mechanism 112 includes a cross-round block 1121. One side of the cross-round block 1121 is fixedly connected to a threaded rod 1122. The outer surface of the threaded rod 1122 is sleeved and threadedly connected to an internally threaded cylinder 1123. The bottom of the internally threaded cylinder 1123 is fixedly connected to a corrugated ring piece 1124. One side of the corrugated ring piece 1124 away from the internally threaded cylinder 1123 is fixedly connected to a docking ring block 1125. One side of the cross-round block 1121 close to the threaded rod 1122 is fixedly connected to a vertical vertical rod 1126. The outer surface of the vertical vertical rod 1126 is fixedly connected to a side brush 1127. One end of the internally threaded cylinder 1123 away from the corrugated ring piece 1124 is fixedly connected to the outer surface of the recycling housing 1. One side of the cross-round block 1121 away from the threaded rod 1122 is rotatably connected to one side of the V-shaped scraper 111 through a rotating bolt. One side of the docking ring block 1125 away from the corrugated ring piece 1124 is rotatably connected to one side of the cross-round block 1121 through a bearing. There are multiple vertical vertical rods 1126, and the multiple vertical vertical rods 1126 are distributed on one side of the cross-round block 1121;

[0054] The pressing device 12 includes a second curved plate 121. A second electric push rod 122 is fixedly connected to the inner side of the second curved plate 121. A driving shaft of the second electric push rod 122 is fixedly connected to a square pressing plate 123. A square sponge pad 124 is fixedly connected to a side of the square pressing plate 123 away from the second electric push rod 122. A top-opening circular groove 125 is formed in the top of the square sponge pad 124. A circular gasket 126 is fixedly connected to the bottom of the inner wall of the top-opening circular groove 125. A return spring 127 is fixedly connected to the top of the circular gasket 126. A thin through rod 128 is fixedly connected to the top of the circular gasket 126. The bottom of the second curved plate 121 is fixedly connected to the top of the side support plate 10. There are multiple top-opening circular grooves 125, and the multiple top-opening circular grooves 125 are distributed on the top of the square sponge pad 124. The outer side of the return spring 127 is fixedly connected to the inner wall of the top-opening circular groove 125. The top of the thin through rod 128 penetrates through the square pressing plate 123 and is slidably connected to the square pressing plate 123. When in use, when the position of the V-shaped scraper 111 needs to be adjusted, twist the cross-round block 1121 to drive the threaded rod 1122 on one side to rotate. When the threaded rod 1122 rotates, it is in threaded cooperation with the internal thread cylinder 1123 to move. By twisting the cross-round block 1121 to drive the threaded rod 1122 in threaded cooperation with the internal thread cylinder 1123, the distance between the V-shaped scraper 111 and the inner side of the recycled plastic film 14 is adjusted. When the cross-round block 1121 rotates, it rotates and moves together with the threaded rod 1122 through the threaded cooperation between the threaded rod 1122 and the internal thread cylinder 1123. When the cross-round block 1121 moves, it drives the docking ring block 1125 and the vertical vertical rod 1126 on one side to move together. When the docking ring block 1125 moves, it drives the corrugated ring piece 1124 on one side to expand or contract. By arranging the corrugated ring piece 1124 that expands or contracts on the outer side of the threaded rod 1122, the outer side of the threaded rod 1122 is wrapped and covered. By the rotational connection between the docking ring block 1125 and the cross-round block 1121, the corrugated ring piece 1124 is driven to expand or contract. The vertical vertical rod 1126 that rotates together with the cross-round block 1121 drives the side brush 1127 on its outer surface to rotate together. When the side brush 1127 rotates with the vertical vertical rod 1126, it frictionally cleans the outer surface of the corrugated ring piece 1124. The second electric push rod 122 is used to push the square pressing plate 123 to move downward. When the square pressing plate 123 moves downward, it pushes the square sponge pad 124 at the bottom to move downward together. When the square sponge pad 124 moves downward to contact the recycled plastic film 14 on the surface of the linkage roller 9, it is continuously compressed by the square pressing plate 123. By arranging the flexible square sponge pad 124 between the square pressing plate 123 and the recycled plastic film 14, the recycled plastic film 14 is pressed and attached. When the square sponge pad 124 is squeezed, the return spring 127 inside is compressed by the square pressing plate 123 together. The gradually downward moving square pressing plate 123 and the thin through rod 128 penetrating through the square pressing plate 123 have a relative displacement. By arranging the thin through rod 128 penetrating through the square pressing plate 123 on the circular gasket 126, the square sponge pad 124 is fixed and limited.An elastic interval is provided by arranging a circular gasket 126 between the square sponge pad 124 and the thin through rod 128. When it is not necessary to flexibly press the recycled plastic film 14, the square pressing plate 123 is driven to move upward by the second electric push rod 122. At this time, the return spring 127 loses the pressure of the square pressing plate 123, and the return spring 127 that loses pressure drives the square sponge pad 124 to expand and recover through the stretching force.

[0055] When the present invention is in operation and it is necessary to recycle the farmland plastic film, first lift a part of the plastic film and bypass the linkage roller 9 from the bottom of the recycling housing 1, pass through the arc-shaped through hole 13, and finally fix it on the winding roller 7. Connect and fix the traction rod 3 to the tensile machine. Drive the traction rod 3 through the tensile machine to drive the movement of the plastic film recycling housing 1. When the recycling housing 1 moves, it drives the circular cutter discs 4 and the film shoveling plates 6 on both sides to move together. The circular cutter discs 4 on both sides first cut and separate the plastic film from the soil, and then the film shoveling plates 6 shovel up the plastic film in the soil. Start the drive motor 8 to drive the winding roller 7 to rotate to wind and recycle the shoveled plastic film. When the recycled plastic film 14 moves around the linkage roller 9, its inner side is always in contact with the stubble removing device 11. The stubble removing device 11 scrapes and cleans the soil, stubble, and stones attached to the recycled plastic film 14. At the same time, the flexible pressing device 12 is used to flexibly press the recycled plastic film 14 on the linkage roller 9. When the recycled plastic film 14 is pulled by the winding roller 7 and moves around the linkage roller 9, its inner side is always in contact with the V-shaped scraper 111. The V-shaped scraper 111 scrapes and cleans the soil, stubble, and stones attached to the recycled plastic film 14. An elastic V-shaped plastic pad 113 is arranged outside the V-shaped scraper 111 to elastically resist a large amount of lifted soil and stones. The electric push rod 1 pulls the V-shaped thin plate 116 to move towards the adjusting mechanism 112. When the V-shaped thin plate 116 moves towards the adjusting mechanism 112, it scrapes and discharges the soil, stones and other sundries accumulated inside the V-shaped scraper 111. When the V-shaped thin plate 116 approaches the recycled plastic film 14, the sieve stubble round holes 117 opened on its surface are intermittently inserted into contact with the fine strip-shaped sundries such as stubble on the surface of the recycled plastic film 14. By opening a plurality of sieve stubble round holes 117 on the surface of the V-shaped thin plate 116, the fine strip-shaped sundries such as stubble on the recycled plastic film 14 are peeled and sieved. When the inner side of the recycled plastic film 14 is not in tight contact with the side of the V-shaped scraper 111, the distance between the V-shaped scraper 111 and the inner side of the recycled plastic film 14 is adjusted through the adjusting mechanism 112. When it is necessary to adjust the position of the V-shaped scraper 111, twist the cross-shaped round block 1121 to drive the threaded rod 1122 on one side to rotate. When the threaded rod 1122 rotates, it is in threaded cooperation with the internal threaded cylinder 1123 to move. The distance between the V-shaped scraper 111 and the inner side of the recycled plastic film 14 is adjusted by twisting the cross-shaped round block 1121 to drive the threaded rod 1122 in threaded cooperation with the internal threaded cylinder 1123. When the cross-shaped round block 1121 rotates, it rotates and moves together with the threaded rod 1122 through the threaded cooperation between the threaded rod 1122 and the internal threaded cylinder 1123. When the cross-shaped round block 1121 moves, it drives the docking ring block 1125 and the vertical vertical rod 1126 on one side to move together. When the docking ring block 1125 moves, it drives the corrugated ring piece 1124 on one side to expand or contract. The outer side of the threaded rod 1122 is wrapped and covered by arranging the corrugated ring piece 1124 that cooperates with the expansion or contraction on the outer side of the threaded rod 1122. The corrugated ring piece 1124 is driven to expand or contract by the rotational connection between the docking ring block 1125 and the cross-shaped round block 1121.The vertical vertical rod 1126 that rotates together with the cross-shaped circular block 1121 drives the side brush 1127 on the outer surface to rotate together. When the side brush 1127 rotates with the vertical vertical rod 1126, it frictionally cleans the outer surface of the corrugated ring 1124. The electric push rod two 122 pushes the square pressing plate 123 to move downward. When the square pressing plate 123 moves downward, it drives the square sponge pad 124 at the bottom to move downward together. When the square sponge pad 124 moves downward to contact the recycled plastic film 14 on the surface of the linkage roller 9, it is continuously squeezed and compressed by the square pressing plate 123. By setting a flexible square sponge pad 124 between the square pressing plate 123 and the recycled plastic film 14 to press the recycled plastic film 14, when the square sponge pad 124 is squeezed, the return spring 127 inside is compressed by the square pressing plate 123 together. The gradually descending square pressing plate 123 has a relative displacement with the thin through rod 128 that penetrates the square pressing plate 123. By setting the thin through rod 128 that penetrates the square pressing plate 123 on the circular gasket 126 to fix and limit the square sponge pad 124, and by setting a circular gasket 126 between the square sponge pad 124 and the thin through rod 128 for elastic spacing. When it is not necessary to flexibly press the recycled plastic film 14, the electric push rod two 122 drives the square pressing plate 123 to move upward and return. At this time, the return spring 127 loses the pressure of the square pressing plate 123, and the return spring 127 that loses pressure drives the square sponge pad 124 to expand and recover through the stretching force.,
