Description

Technical Field

[0001] This application relates to the technical field of debris collection devices, and specifically relates to a two-way (two-way means it can roll in both clockwise and counterclockwise directions) mechanical debris rolling structure. Background Art

[0002] Currently, there is a small desktop debris collection and cleaning device on the market, which is generally used for collecting debris on the desktop, especially for collecting debris generated by eraser wiping, and is mainly used by students. For the existing such cleaning device, generally a small motor is set inside the housing as the power for debris absorption. Because a motor needs to be equipped, it will cause its overall structure to be relatively large, making it not easy to store and carry. Moreover, this device needs to set up a space for accommodating the motor, a space for accommodating the battery, a space for storing debris, and corresponding assembly and clamping structures, and also needs to set up a disassembly structure to disassemble the structure when dumping debris. Therefore, the overall structure is relatively complex and the manufacturing cost is relatively high. In addition, due to the setting of the motor inside, the motor drive may pose certain safety hazards to children, and there will also be relatively large noise generated during the working process due to the operation of the motor. Summary of the Invention

[0003] In view of the above deficiencies of the prior art, this application provides a two-way mechanical debris rolling structure that is convenient for debris collection and dumping, does not require disassembling components, does not require setting a driving motor, thus has no noise and can reduce safety hazards.

[0004] To solve the above technical problems, the technical solution adopted in this application is: a two-way mechanical debris rolling structure, which includes a main bracket. A debris rolling collection structure is arranged on the main bracket. The debris rolling collection structure includes a collection roller that can rotate circumferentially and is connected to the main bracket, a scraper arranged on the main bracket, a pull-out cover connected to the main bracket, and a rotary cover sleeved outside the pull-out cover. The scraper is used for scraping the collection roller. The pull-out cover is arranged outside the scraper and a collection bin is formed between the scraper and the pull-out cover. The rotary cover can rotate circumferentially relative to the pull-out cover.

[0005] With the above structure, this two-way mechanical debris rolling structure of this application does not need to set up a power drive structure, can effectively reduce costs, and the structure is effectively simplified. There is no noise generated during the operation process, and it is safer and more conducive to the use of children. In addition, this application sets up a rotary cover structure. When bonding debris, the rotary cover can be placed in a position coinciding with the pull-out cover, without interfering with the action of the collection roller. When the collection is completed and the debris needs to be dumped, the rotary cover can be rotated to the opposite side of the pull-out cover. At this time, the pull-out cover can be axially pulled outwards to dump the debris inside. There is no need to disassemble the rotary cover, and only by pulling the pull-out cover relative to the main bracket, the dumping can be completed. Moreover, the structure of this application is a cylindrical structure similar to a writing pen, occupying a small space and being easier to store and carry.

[0006] Furthermore, the collecting roller includes a roller rotatably connected to the main bracket, and a rubber sleeve sleeved outside the roller. The outer diameter of the rubber sleeve protrudes from the outer diameter of the main bracket. With the above structure, the adhesion performance of the rubber sleeve is used to achieve the adhesion and collection of debris, and the outer diameter of the rubber sleeve protrudes from the outer diameter of the main bracket, so that it can be in full contact with the debris and improve the adhesion efficiency.

[0007] Furthermore, a clamping strip extends from the inner wall of the pull-out cover, and a clamping opening is provided on the corresponding main bracket. The clamping strip is clamped in the clamping opening and can be axially pulled back and forth along the clamping opening. With this structure, the pull-out cooperation between the pull-out cover and the main bracket is realized, and the structure is simpler. Moreover, when pouring out the debris, it is not necessary to completely detach the pull-out cover from the main bracket. Pulling out a certain distance relative to the main bracket can achieve the pouring of the debris.

[0008] Furthermore, the screw cap includes a screw cap body covering the outside of the main bracket. One end of the screw cap body in the axial direction is provided with a connecting cover plate, and the other end is provided with a collar. The connecting cover plate is buckled on the end cover of the main bracket, and the collar is sleeved on the outer peripheral wall of the main bracket, and the screw cap can rotate circumferentially relative to the main bracket. With the above structure, the rotational connection between the screw cap and the main bracket can be realized, so that the screw cap can be in the following two positions: overlapping with the pull-out cover, at this time the collecting roller is exposed to roll and collect debris; opposite to the pull-out cover, the pull-out cover can be pulled out relative to the main bracket to achieve the pouring of debris; it can also effectively enclose the collecting roller, effectively protect the collecting roller when it is not necessary to roll and collect debris, and can also prevent the adhered debris from leaking.

[0009] Furthermore, an axially outwardly protruding buckle is provided on the end cover of the main bracket, and a clamping hole for clamping and sleeving with the buckle is provided on the connecting cover plate. The buckle is composed of three split blocks, and a Y-shaped gap is formed between the three mutually combined split blocks. With the above structure, the clamping hole can be sleeved on the buckle, and the three split blocks are squeezed and gathered towards the middle by the acting force of the clamping hole. After the clamping hole passes through the head of the buckle, it is sleeved on the main body of the buckle. At this time, the three split blocks are separated again to expand the outer diameter of the head, and the clamping hole will not become loose when sleeved on the buckle. In this way, the screw cap can rotate circumferentially relative to the buckle body through the clamping hole and will not be separated from the main body bracket.

[0010] Further, a positioning buckle is provided on the connecting cover plate, and correspondingly, positioning holes for buckling with the positioning buckle are provided on the end cover of the main bracket. Two positioning holes are provided, which are respectively used for positioning when the rotary cover and the sliding cover overlap and are in relative positions. With the above structure, whether the rotary cover overlaps with the sliding cover or is in a relative position with the sliding cover, effective positioning can be achieved (just rotate the positioning buckle into the corresponding positioning hole), preventing the rotary cover from being misaligned in the above two positions and affecting the use of the overall structure.

[0011] Furthermore, an elastic sheet is provided on the connecting cover plate, and the positioning buckle is arranged on the bottom surface of the elastic sheet. With this structure, the elastic deformation force of the elastic sheet can be used to easily rotate the positioning buckle into different positioning holes, and effective buckling between the positioning buckle and the positioning hole can also be achieved. Specifically, the elastic sheet can be a part of the connecting cover plate, with a gap between the two, and is connected to one side of the connecting cover plate to achieve the performance of elastic deformation.

[0012] Further, two scraping plates are provided, extending along the axial direction of the main bracket, and a spacing is provided between the two scraping plates, and the rubber sleeve fills the spacing. With the above structure, during the rolling of the bonded debris on the rubber sleeve, the debris on it can be scraped off and enter the collection bin through contact with the scraping plates. Moreover, no matter whether the rubber sleeve rotates clockwise or counterclockwise, it can be ensured that one of the scraping plates can scrape off the debris on it.

[0013] Furthermore, both of the two scraping plates are inclined downward from the outer end to the inner end adjacent to the rubber sleeve. The scraping plates arranged in this way can form an effect of collecting and gathering, making it easier to scrape and collect the debris.

[0014] Furthermore, a separation slit is provided on each scraping plate, and the separation slit divides the scraping plate into multiple small scraping plates. With the above structure, the setting of the separation slit can endow the whole scraping plate with a certain elastic deformation force, making the scraping plate and the rubber sleeve in elastic contact during the process of scraping off the debris in contact with the rubber sleeve, avoiding wear caused by hard contact, and the elastic force can keep the scraping plate and the rubber sleeve in effective contact all the time.

[0015] Further, an eraser structure is also provided on the main bracket of the present application, and the eraser structure and the rolling debris collection structure are arranged opposite to each other along the axial direction of the main bracket. With this structure, both the eraser structure and the rolling debris collection structure are arranged on the main bracket, saving more space and eliminating the need to separately set an eraser structure, realizing the integration of two functions in one device.

[0016] Further, the eraser structure is nested within the main bracket and can telescopically move back and forth along the axial direction of the main bracket; with the above structure, the eraser can be telescopically placed within the main bracket, the length of the eraser protruding from the main bracket can be adjusted according to actual usage needs, and the replacement of the eraser can also be achieved.

[0017] Furthermore, the eraser structure includes an eraser seat, an eraser sleeved on the eraser seat, the eraser seat is sleeved within the main bracket, and the main bracket and the eraser seat are interconnected by a button, and the button is used to toggle the eraser seat to axially move relative to the main bracket; with the above structure, the position of the eraser can be flexibly adjusted to facilitate the operation of the eraser.

[0018] Furthermore, the main bracket is provided with a rack along the axial direction, the button is provided with a clamping position, and the clamping position matches the tooth position of the rack; with the above structure, when the button is pressed downwards, the position where the eraser seat is pressed by the button moves downwards, driving the clamping position of the button to disengage from the rack of the main bracket. At this time, the button can be pushed to drive the eraser to an appropriate telescopic length. After that, when the button is released, the eraser seat resets, and the clamping position on the button will enter the tooth position at the corresponding position to achieve the positioning of the eraser and fix the eraser.

[0019] Furthermore, the button is provided with a connecting block, and the corresponding eraser seat is provided with a connecting hole matching the connecting block, and the length direction of the connecting hole extends along the axial direction of the main bracket; with the above structure, when installing the button, the connecting block can be first placed along the axial direction of the main bracket into the connecting hole, and then rotated 90 degrees. The connecting block abuts against the inner wall of the eraser seat to achieve the connection between the button and the eraser seat. When disassembling the two, only need to rotate the button 90 degrees again so that the connecting block is aligned with the length of the connecting hole, and the button can be pulled out from the connecting hole.

[0020] Further, the inner wall of the main bracket sleeving the eraser is provided with axially extending ribs, and the outer walls of the corresponding eraser seat and the eraser are provided with axially extending grooves, and the ribs are in sliding fit within the grooves; with this structure, the position guiding and limiting functions can be realized during the telescopic process of the eraser, preventing the eraser from twisting and affecting the reset of the button.

[0021] Further, the inner wall of the pull-out cover is provided with an inwardly protruding annular rib, and the outer wall of the corresponding main bracket is provided with an annular groove, and the annular rib is used to engage with the annular groove; with this structure, during the process of collecting debris, the effective fixation between the pull-out cover and the main bracket can be ensured, preventing the pull-out cover from sliding relative to the main bracket and causing debris leakage; the height or depth of the protrusion and the groove is limited and will not affect the subsequent pulling of the pull-out cover.

[0022] Further, an outwardly protruding force - applying portion extends from the outer sidewall of the screw - cap. The force - applying portion is used to drive the screw - cap to rotate circumferentially. With the above - mentioned structure, during the process of circumferentially rotating the screw - cap, force can be applied through the force - applying portion, making it more convenient to drive it to the required position.

[0040] As attached Figures 1-5, as shown in Fig. 8, a two-way mechanical chip rolling structure of the present application includes a main bracket 1. A chip rolling collection structure is provided on the main bracket 1. The chip rolling collection structure includes a collection roller 2 rotatable circumferentially connected to the main bracket 1, a scraper 3 provided on the main bracket 1, a pull-out cover 4 connected to the main bracket 1, and a rotary cover 5 sleeved outside the pull-out cover 4. The scraper 3 is used for scraping the collection roller (that is, during the rotation of the collection roller, the debris on it will be scraped off by the scraper). The pull-out cover 4 is arranged outside the scraper 3 to form a collection bin 6 between the pull-out cover and the scraper 3 (the pull-out cover is located on the opposite side of the collection roller for collecting debris). The rotary cover 5 can rotate circumferentially relative to the pull-out cover 4.

[0041] With the above structure, this two-way mechanical chip rolling structure of the present application does not require a power drive structure, which can effectively reduce costs, and the structure is effectively simplified (without a motor storage bin, a battery storage bin, etc.). There is no noise generated during operation, and it is safer and more suitable for children to use. In addition, the present application is provided with a rotary cover structure. When bonding debris, the rotary cover can be placed in a position overlapping with the pull-out cover (radially overlapping), which does not interfere with the operation of the collection roller. When the collection is completed and the debris needs to be dumped, the rotary cover can be rotated to the opposite side of the pull-out cover (radially opposite side). At this time, the pull-out cover can be pulled outwards to dump the debris inside. There is no need to disassemble the rotary cover, and only by pulling the pull-out cover relative to the main bracket, the dumping can be completed. Moreover, this structure of the present application is a cylindrical structure similar to a pen, which occupies a small space and is easier to store and carry.

[0042] As shown in the attached Figures 2-7 , the collection roller 2 described in the present application includes a roller 201 rotatably connected to the main bracket 1 (shafts are provided at both axial ends of the roller and are sleeved with bushings at corresponding positions of the main bracket to achieve rotational connection). A rubber sleeve 202 is sleeved outside the roller 201 (the rubber sleeve is made of a soft rubber material with adhesive properties and can adhere to debris). The outer diameter of the rubber sleeve 202 protrudes from the outer diameter of the main bracket 1 (that is, along the radial direction, the rubber sleeve protrudes beyond the outer wall of the main bracket, which is convenient for full contact with the surface to be cleaned to bond debris). With the above structure, the bonding and collection of debris are realized through the adhesive property of the rubber sleeve, and the outer diameter of the rubber sleeve protrudes from the outer diameter of the main bracket, which can be in full contact with the debris and improve the bonding efficiency.

[0043] As shown in the attached Figure 7 , 10As shown in Figure -11, a clamping strip 401 extends from the inner wall of the draw - out cover 4 of the present application (clamping strips are provided on the inner walls at both axial ends), and a bayonet 101 is provided on the corresponding main bracket 1 (extending axially for convenient sliding fit with the clamping strip). The clamping strip 401 is clamped in the bayonet 101 and can be axially pulled back and forth along the bayonet 101; that is, through the axial sliding fit of the clamping strip and the bayonet, the draw - out connection between the draw - out cover and the main bracket is realized. This structure is simpler, and when pouring debris, it is not necessary to completely detach the draw - out cover from the main bracket. It is only necessary to pull out a certain distance relative to the main bracket to realize the pouring of debris.

[0044] As shown in the attached Figure 1 , 6 As shown in Figures -7 and 10, the screw - on cap 5 of the present application includes a screw - on cap body 501 covering the outside of the main bracket 1. One end of the screw - on cap body 501 in the axial direction is provided with a connecting cover plate 502 (a radially extending cover plate), and the other end is provided with a collar 503 (the collar here can be an open - type collar, not completely closed). The connecting cover plate 502 is buckled on the end cover 102 of the main bracket 1, and the collar 503 is sleeved on the outer peripheral wall of the main bracket 1, and the screw - on cap 5 can rotate circumferentially relative to the main bracket 1; adopting the above - mentioned structure, the rotational connection between the screw - on cap and the main bracket can be realized, so that the screw - on cap is in the following two positions: overlapping with the draw - out cover in the radial direction, at this time the collecting roller is exposed and can roll to collect debris; being arranged radially opposite to the draw - out cover and complementary to each other, the end of the draw - out cover is exposed and can be pulled out relative to the main bracket to realize the pouring of debris; it can also effectively enclose the collecting roller and effectively protect the collecting roller when it is not necessary to roll and collect debris.

[0045] As shown in the attached Figures 1-7 As shown in the figure, a buckle 103 protruding axially outward is provided on the end cover 102 of the main bracket 1 of the present application, and a card hole 504 for clamping and sleeving with the buckle 103 is provided on the connecting cover plate 501. The buckle 103 is composed of or formed by three - petal block structures, and a Y - shaped gap is formed between the three mutually combined blocks (the setting of the gap can enable the blocks to scale, facilitating the buckling and detachment with the card hole); adopting the above - mentioned structure, the card hole can be sleeved on the buckle, and the three - petal blocks are squeezed and gathered towards the middle by the acting force of the card hole. After the card hole passes through the head of the buckle, it is sleeved on the main body of the buckle. At this time, the three - petal blocks are separated again to expand the outer diameter of the head, and the card hole sleeved on the buckle will not become loose. In this way, the screw - on cap can rotate circumferentially relative to the buckle main body through the card hole and will not be detached from the main body bracket. Here, the height of the card hole is adapted to the height of the buckle collar part to avoid large axial displacement of the cover plate.

[0046] As shown in the attached Figures 1-7As shown in the figure, the connection cover plate 502 of the present application is provided with positioning buckles 505, and corresponding positioning holes 104 for buckling with the positioning buckles 505 are provided on the end cover 102 of the main bracket 1. There are two positioning holes 104, which are respectively used for positioning when the rotary cover 5 and the drawer cover 4 overlap and are in relative positions (the two positioning holes are symmetrically distributed along the radial direction of the end cover); with the above structure, whether the rotary cover overlaps with the drawer cover or is in a position opposite to the drawer cover, effective positioning can be achieved (by rotating the positioning buckle into the corresponding positioning hole), preventing the rotary cover from being misaligned in the above two positions and affecting the use of the overall structure.

[0047] As shown in the attached Figure 1 、 6 -7, 13, an elastic piece 506 is provided on the connection cover plate 502 of the present application, and the positioning buckle 505 is arranged on the bottom surface of the elastic piece 506 (the surface close to the positioning hole side); with this structure, the elastic deformation force of the elastic piece can be used to easily rotate the positioning buckle into different positioning holes, and effective buckling between the positioning buckle and the positioning hole can also be achieved; specifically, the elastic piece can be a part of the connection cover plate, and there is a gap between the two, and it is connected to one side of the connection cover plate to achieve the performance of elastic deformation.

[0048] As shown in the attached Figure 8 、 14 As shown in the figure, two scraping plates 3 are provided in the present application, both extending along the axial direction of the main bracket 1, and a spacing 301 is provided between the two scraping plates 3 (that is, the free ends of the two scraping blades do not touch, facilitating the discharge of debris), and the rubber sleeve 202 fills the spacing (that is, there is a rubber sleeve between the spacings, facilitating the debris on it to enter the collection bin, and the two scraping plates, the main bracket, the drawer cover and the collection roller enclose to form a collection bin); with the above structure, during the rolling process of the rubber sleeve bonding debris, the debris on it can be scraped off and enter the collection bin by contacting the scraping plate, and no matter whether the rubber sleeve rotates clockwise or counterclockwise, it can be ensured that one of the scraping plates can scrape off the debris on it.

[0049] As shown in the attached Figure 8 As shown in the figure, both of the two scraping plates 3 of the present application are inclined downward from the outer end (the end connected to the main bracket) to the inner end (close to the rubber sleeve end) and are adjacent to the rubber sleeve 202 (the adjacent here can be that they are in contact and fit with each other or have a very small gap, and this gap can meet the requirement that the debris on the collection roller can be scraped off by the scraping plate during the rolling process); this inclined scraping plate can form a collection and gathering effect, making it easier to scrape off and collect the debris.

[0050] As shown in the attached Figure 14As shown, a separation seam 302 is provided on each scraper 3 of the present application. The separation seam 302 divides the scraper 3 into multiple small scrapers. With the above structure, the setting of the separation seam can endow the whole scraper with a certain elastic deformation force. During the process of scraping debris in contact with the rubber sleeve, the scraper and the rubber sleeve are in elastic contact, avoiding wear caused by hard contact, and the elastic force can keep the scraper and the rubber sleeve in effective contact or effectively scrape debris all the time.

[0051] The scraper of the present application is located on the main bracket and is positioned between the collection bin and the collection roller, which can not only facilitate the scraping of debris on the collection roller but also facilitate the entry of debris into the collection bin. Moreover, the scraper isolates the debris on the collection roller and in the collection bin, and can prevent the debris in the collection bin from adhering to the collection roller again.

[0052] As shown in the appendix Figures 1-5 As shown, an eraser structure is also provided on the main bracket 1 of the present application. The eraser structure and the rolling debris collection structure are arranged oppositely along the axial direction of the main bracket 1 (that is, one is arranged at one axial end of the main bracket and the other is arranged at the other axial end along the axial direction of the main bracket, and both structures are arranged on the main bracket). With this structure, both the eraser structure and the rolling debris collection structure are arranged on the main bracket, which saves more space and does not require a separate eraser structure, realizing the integration of two functions in one device, which is convenient for storage and use.

[0053] As shown in the appendix Figures 1-5 As shown, the eraser structure of the present application is sleeved in the main bracket 1 and can axially move back and forth along the main bracket 1 (that is, the eraser can be retracted into the main bracket or protrude from the main bracket for convenient use). With the above structure, the eraser can be telescopically placed in the main bracket, and the length of the eraser protruding from the main bracket can be adjusted according to actual use needs, and the eraser can also be replaced.

[0054] As shown in the appendix Figures 1-7 As shown, the eraser structure of the present application includes an eraser seat 7 and an eraser 8 sleeved on the eraser seat 7. The eraser seat 7 is sleeved in the main bracket 1, and the main bracket 1 and the eraser seat 7 are connected to each other by a button 9 (a bracket is provided at the front end of the eraser seat, and a hole connected to the button is provided on the bracket), and the button 9 is used to move the eraser seat 7 axially relative to the main bracket 1. With the above structure, the position of the eraser can be flexibly adjusted to facilitate the work of the eraser.

[0055] As shown in the appendix Figures 6-7As shown, the main bracket 1 of the present application is provided with racks 105 (two rows of parallel racks) along the axial direction. The button 9 is provided with a clamping position 901, and the clamping position 901 matches the tooth positions of the racks 105. Specifically, there are two racks with a spacing therebetween, forming a space for the clamping position to engage. When the button is pressed downward, the position of the rubber seat pressed by the button moves downward, driving the clamping position of the button to disengage from the racks of the main bracket. At this time, the button can be pushed to drive the rubber to an appropriate telescopic length. Then, when the button is released, the rubber seat resets, and the clamping position on the button will enter the tooth positions at the corresponding positions, realizing the positioning of the rubber and fixing the rubber.

[0056] As shown in the attached Figures 6-7 As shown, the button 9 of the present application is provided with a connecting block 902. Correspondingly, the rubber seat 7 is provided with a connecting hole 701 that matches the connecting block 902. The length direction of the connecting hole 701 extends along the axial direction of the main bracket 1. With the above structure, when installing the button, the connecting block can be first placed along the axial direction of the main bracket into the connecting hole and then rotated 90 degrees. The connecting block abuts against the inner wall of the rubber seat, realizing the connection between the button and the rubber seat. When disassembling the two, only need to rotate the button 90 degrees again to pull out the button from the connecting hole.

[0057] As shown in the attached Figures 6-7 As shown in FIGS. 14, on the inner wall of the main bracket 1 sleeving the rubber 8, there are axially extending ribs 106. Correspondingly, on the outer walls of the rubber seat 7 and the rubber 8, there are axially extending grooves 10. The ribs 106 are slidably fitted in the grooves 10 (both the grooves and the ribs are provided with two and are symmetrically distributed along the radial direction of their respective components). With this structure, it can ensure the position guiding and positioning functions during the telescopic process of the rubber, preventing the rubber from twisting and affecting the reset of the button.

[0058] As shown in the attached Figures 6-7 As shown, on the inner wall of the pull-out cover 4 of the present application, there is an inwardly protruding annular rib 402. Correspondingly, on the outer wall of the main bracket 1, there is an annular groove 107. The annular rib 402 is used to engage with the annular groove 107. With this structure, during the process of collecting debris, it can ensure the effective fixation between the pull-out cover and the main bracket, preventing the pull-out cover from sliding relative to the main bracket and causing debris leakage. The height or depth of the protrusion and the groove is limited and will not affect the subsequent pulling of the pull-out cover.

[0059] As shown in the attached Figure 13 As shown, on the outer side wall of the screw cap 5 of the present application, there extends an outwardly protruding force-applying portion 507. The force-applying portion 507 is used to drive the screw cap 5 to rotate circumferentially. With the above structure, during the process of needing to rotate the screw cap circumferentially, force can be applied through the force-applying portion, making it more convenient to drive it to the required position.

[0060] The main bracket of this application is a cylindrical long strip structure similar to a writing pen, and the structures of other cooperating components are adapted to their positions; on the inner wall of the pull-out cover of the main bracket of this application, a support rod is also provided, which fits with the inner wall of the pull-out cover, facilitating the smooth operation of the pull-out cover during the pulling process; each component constituting the two-way mechanical chip rolling structure of this application can be made of plastic parts or materials with deformation performance, having a certain elastic deformation performance, facilitating the assembly and disassembly of each component; especially, the structure of the rubber seat, for example, can move downward at the pressed position when the button is pressed, so that the clamping position of the button is disengaged from the tooth position of the rack, and it can automatically return to the corresponding clamping position when the pressing is released; as shown in the appendix Figure 12 As shown, the clamping position and the connecting block provided on the button are respectively arranged on both sides of the thickness direction of the rubber seat. The lower surface of the clamping position fits with the outer surface of the rubber seat, and the upper surface of the connecting block fits with the inner surface of the rubber seat, so that the button is fixed on the rubber seat.

[0061] The specific working principle and process of the two-way mechanical chip rolling structure of this application: After the rubber in the eraser structure is used, chips are generated on the desktop and need to be cleaned. The rotary cover rotates to a position overlapping with the pull-out cover. At this time, the collecting roller is exposed and can be in contact with the desktop and roll. The sticky rubber sleeve on the collecting roller picks up the chips and rolls the chips to the scraper in the middle of the main bracket, and then they are scraped off by the scraper and stored in the collecting bin; when it is necessary to pour out the chips, the rotary cover is rotated to a position opposite to the pull-out cover. At this time, the end of the pull-out cover is exposed, and the chips can be poured out by axially pulling it outwards; when using the rubber, press the button to cause the pressed position of the rubber seat to deform downward, the clamping position is disengaged from the tooth position, and pushing the button can make the rubber seat move axially to stretch the rubber; the above structure of this application is a complete mechanical structure without electric drive, and its overall is a slender writing pen-shaped structure, which is easier to store and carry. The long strip structure makes the rolling area of the collecting roller larger and can bond more chips. The setting of the rotary cover does not affect the bonding of chips by the collecting roller and can also protect the collecting roller after rotating to the side opposite to the pull-out cover, preventing pollution in scenarios where chips do not need to be bonded and also preventing the chips on the collecting roller from falling and polluting the desktop again; the scraper is arranged between the collecting roller and the collecting bin to isolate the collected chips from the collecting roller, preventing the chips from adhering to the collecting roller again.
