DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figures 1-6 As shown, the present invention is a vertical handle and strip integrated machine, comprising an operating table 1 and a working surface 2. The operating table 1 is fixedly supported on the ground by a support base, and the upper surface of the operating table 1 is provided with a working surface 2 for providing movement of the strip fabric; the upper surface of the operating table 1 is provided with a discharge mechanism 3, a guide mechanism 4, a label storage mechanism 5, a handle storage mechanism 6, a grabbing and transferring mechanism 7, a pressing and conveying mechanism 9 and a cutting and sewing machine 10 in sequence from right to left; the discharge mechanism 3 is used to store the strip fabric roll, and the guide mechanism 4 is used to guide the strip fabric to the work surface At the input end of the working surface 2, the label storage mechanism 5 is used to store labels, and the handle storage mechanism 6 is used to store handle tapes. The grabbing and transferring mechanism 7 grabs the stored labels and handle tapes from the label storage mechanism 5 and the handle storage mechanism 6 and transfers them to the apron fabric conveyed above the working surface 2. The pressing and conveying mechanism 9 is used to press the handles and labels attached to the apron fabric and convey them to the cutting and sewing machine 10. The cutting and sewing machine 10 is used to cut and sew the excess apron fabric and sew the handles and labels to the apron fabric at the same time.

[0031] In the scheme designed by the present invention, when it is necessary to sew the handle and label to the fabric of the strip, the processing personnel will pass the free end of the fabric of the strip stored on the feeding mechanism 3 through the guide mechanism 4 and lay it flat on the working surface 2, and then let the free end of the fabric of the strip pass through the grabbing and transferring mechanism 7, the pressing and conveying mechanism 9 and the cutting and sewing machine 10 in sequence. When it is necessary to transfer the handle tape stored in the handle storage mechanism 6 and the label stored in the label storage mechanism 5 to be attached to the fabric of the strip, the pressing and conveying mechanism 9 will transport the free end of the fabric of the strip to the cutting and sewing machine 10. When cutting and sewing are performed at the sewing machine 10, the suction cup in the handle storage mechanism 6 can place the handle tape in the storage frame into the grabbing and transferring mechanism 7 through the cooperation of multiple telescopic cylinders 78, and then the handle transferring mechanism can move horizontally and lift to place the handle tape vertically on the fabric strip, and then transport it to the cutting and sewing machine 10 through the compacting and conveying mechanism 9, and then the label storage mechanism 5 works later and also places the labels stored in the storage box into the grabbing and transferring mechanism 7 through the cooperation of the suction cup and multiple telescopic cylinders 78. , then the grabbing and transferring mechanism 7 will stick the surface to the rear side of the upper surface of the fabric, and then it will be transported to the cutting and sewing machine 10 through the pressing and conveying mechanism 9. At this time, the cutting and sewing machine 10 will first cut the excess fabric, and then sew the vertical handle tape and label attached to the fabric at the same time. Therefore, the grabbing and transferring mechanism 7 and the pressing and conveying mechanism 9 above the operating table 1 cooperate with each other, which can vertically translate the handle tape stored in the storage frame to the top of the fabric, and then press and convey it to the cutting and sewing machine 10. The mechanism 9 can press the vertical handle strap tightly onto the surrounding fabric and convey it to the cutting and sewing machine 10. At this time, the cutting and sewing machine 10 can not only cut the excess surrounding fabric, but also, due to the cooperation of the pressing and conveying mechanism 9, it will not cause the vertically fitted handle strap to be offset, thereby facilitating the rapid sewing of the two ends of the handle strap onto the surrounding fabric, and thus enabling the handle strap to be accurately sewn onto the cut surrounding fabric, thereby further improving the efficiency of vertical sewing of the mattress handle strap on the surrounding fabric.

[0032] As an embodiment of the present invention, the grabbing and transferring mechanism 7 includes a support frame 71, a straight rack 72, a guide rail 73, a sliding block 74, a support plate 75, a gear 76, a support vertical plate 77, a telescopic cylinder 78, a mounting plate 79 and a clamping assembly 8; the support frame 71 is fixedly supported on the upper surface of the operating table 1, and the support frame 71 is located on the right side of the label storage mechanism 5 and the handle storage mechanism 6; the straight rack 72 and the guide rail 73 are both fixed on the upper surface of the crossbeam of the support frame 71, and the straight rack 72 and the guide rail 73 are perpendicular to the moving direction of the surrounding fabric; the support plate 75 is located on the upper surface of the straight rack 72 and the guide rail 73, and the lower surface of the support plate 75 is fixed with a sliding block 74 slidably arranged on the guide rail 73. A servo motor is fixed to the upper surface of the plate 75; a gear 76 is located on the lower surface of the support plate 75, and the gear 76 is connected to the output shaft of the servo motor fixed on the support plate 75, and the gear 76 is meshed with the spur rack 72 for transmission; a support vertical plate 77 is vertically fixed to the upper surface of the support plate 75, and a telescopic cylinder 78 is vertically fixed on the upper surface of the support vertical plate 77; a mounting plate 79, an L-shaped mounting plate 79 is fixedly connected to the piston rod of the vertically mounted telescopic cylinder 78, and the telescopic cylinder 78 is horizontally fixed to the horizontal plate of the mounting plate 79; a clamping assembly 8 is mounted on the piston rod of the horizontally fixed telescopic cylinder 78, and the clamping assembly 8 is used to perform planar clamping of labels stored in the label storage mechanism 5 and handles in the handle storage mechanism 6;

[0033] When the handle strap needs to be transferred and attached to the fabric strip, it is transported to the cutting and sewing machine 10 through the pressing and conveying mechanism 9. At this time, the control system of the all-in-one machine controls the servo motor on the support plate 75 to work, so that it drives the clamping assembly 8 to slide forward along the support frame 71 to the top of the storage frame through the engagement of the gear 76 and the spur rack 72. The cooperation of the sliding block 74 on the lower surface of the support plate 75 and the guide slide 73 facilitates the stable sliding of the clamping assembly 8. Then, the piston rod of the three-rod telescopic cylinder 78 on the mounting plate 79 is controlled to retract, so that the clamping assembly 8 slides toward the left side of the support plate 75. Then, the piston rod of the single-rod telescopic cylinder 78 on the supporting vertical plate 77 is controlled to extend, so that the clamping assembly 8 drops to the level of the suction cup in the handle storage mechanism 6. Then, the suction cup in the handle storage mechanism 6 is controlled to adsorb the handle strap in the storage frame and slide upward to be flush with the clamping assembly 8. The extension of the piston rod of the telescopic cylinder 78 of the rear three rods will push the clamping assembly 8 to clamp the adsorbed handle belt. At this time, the suction cup will disengage from the adsorption of the handle belt, and then the contraction of the piston rod of the telescopic cylinder 78 of the three rods will drive the pulling belt clamped by the clamping assembly 8 to detach from the top of the storage frame. Then, the reverse rotation of the servo motor on the support plate 75 will drive the handle belt clamped by the clamping assembly 8 to move vertically and fit it onto the surrounding fabric being conveyed. Then, the handle belt clamped on the clamping assembly 8 is pressed onto the surrounding fabric by the pressing and conveying mechanism 9, and then continued to be pressed and conveyed to the cutting and sewing machine 10 for cutting and sewing. At least two other groups of clamping assemblies 8 on the support frame 71 can, with the cooperation of the straight rack 72, gear 76 and multiple telescopic cylinders 78, clamp the label that rises and is adsorbed in the label box, transfer it to the surrounding fabric, and press it to the cutting and sewing machine 10 for sewing through the cooperation of the pressing and conveying mechanism 9 on one side.

[0034] As an embodiment of the present invention, the clamping assembly 8 includes a connecting block 81, a side vertical plate 82, a positioning block 83, a sliding splint 84 and a fixed splint 85; the connecting block 81 is fixedly connected to the right side of the side panel, and the outer side surface of the connecting block 81 is connected to the piston rod of the horizontally fixed telescopic cylinder 78, the telescopic cylinder 78 is vertically fixed above the left side surface of the side vertical plate 82, and the lower end surface of the piston rod of the cover telescopic cylinder 78 is connected to the sliding splint 84 through the positioning block 83, the sliding splint 84 is slidably fitted to the left side of the side vertical plate 82, and the fixed splint 85 is fixedly provided on the lower left surface of the side vertical plate 82, the sliding splint 84 and the fixed splint 85 are aligned up and down, and the sliding splint 84 and the fixed splint 85 are both formed with two U-shaped notches 86, and the left side of the U-shaped notch 86 is open;

[0035] In the scheme designed by the present invention, when the meshing transmission of the gear 76 and the spur rack 72 drives the support plate 75 to move to one side of the storage frame, the piston rod of the telescopic cylinder 78 fixed on the left side of the side vertical plate 82 is contracted, causing it to drive the sliding splint 84 to slide up and down along the left side of the side vertical plate 82, thereby opening the sliding splint 84 and the fixed splint 85 to a certain distance. When the suction cup absorbs the stored handle belt from the storage frame upward, the piston rod of the three-rod telescopic cylinder 78 on the mounting plate 79 extends and drives the opened sliding splint 84 and the fixed splint 85 to move to the pulling belt through the connecting block 81 and the side vertical plate 82. , so that the pulling belt is located between the sliding splint 84 and the fixed splint 85, and the suction cup adsorbed on the handle belt will be located in the two U-shaped notches 86 respectively opened on the two splints, so that the suction cup will not interfere with the sliding splint 84 and the fixed splint 85, and then the piston rod of the telescopic cylinder 78 fixed on the side plate 82 is controlled to extend, so that it drives the sliding splint 84 to slide downward through the positioning block 83 to clamp the handle belt between the sliding splint 84 and the fixed splint 85, and at the same time the suction cup will disengage the adsorption of the handle belt, and at this time the piston rod of the three-rod telescopic cylinder 78 on the mounting plate 79 is controlled to retract, so that it drives the sliding splint 84 through the sliding splint 84 The handle belt clamped by the fixed splint 85 disengages from the top of the storage frame and slides to the right. Then, the rotating gear 76 and the spur rack 72 cooperate to transfer the clamped handle belt to the upper surface of the fabric of the surrounding strip. At this time, the lower surface of the fixed splint 85 will contact the surface of the fabric of the surrounding strip, and the two left-side open U-shaped notches 86 aligned with the sliding splint 84 and the fixed splint 85 will be aligned with the two symmetrical pressing and conveying mechanisms 9. At this time, the piston rod of the telescopic cylinder 78 on the side plate 82 can be controlled to retract a small distance, so that the sliding splint 84 moves upward to disengage the clamping of the handle belt, and then the pressing and conveying mechanism 9 will fit to the fabric of the surrounding strip. The handle strap on the fabric is transferred from between the fixed splint 85 and the sliding splint 84 and pressed onto the fabric of the surrounding strip, and then the handle strap and the fabric of the surrounding strip are synchronously conveyed to the cutting and sewing machine 10 through the pressing and conveying mechanism 9, so that the excess edge material of the fabric of the surrounding strip can be cut, and then the compressed vertical handle strap is sewn and fixed. When the pulling strap is disengaged from between the sliding splint 84 and the fixed splint 85, the rotation of the gear 76 and the meshing of the spur rack 72 continue to drive the clamping assembly 8 to move to the storage frame, and continue to automatically repeat the above actions, so that the handle strap of the storage frame can be automatically transferred vertically and attached to the fabric of the surrounding strip.

[0036] As an embodiment of the present invention, the pressing and conveying mechanism 9 includes a supporting ear plate 91, a hinged column 92, a pressing ear plate 93, an articulated cylinder 94, a guide wheel 95, a pressing wheel 96, a driving pulley 97 and a conveyor belt 98; the supporting ear plate 91, the two supporting ear plates 91 are respectively vertically slidably arranged on the bodies of the two cutting and sewing machines 10, and the inner side surface of the inclined lower end of the supporting ear plate 91 is hingedly installed with a pressing ear plate 93 through a hinged column; the pressing ear plate 93, the lower outer side surface of the pressing ear plate 93 is rotatably installed with at least two pressing wheels 96, and the connection between the pressing ear plate 93 and the supporting ear plate 91 is installed with a guide wheel 95; the articulated cylinder 94, the articulated cylinder The fixed section of the cylinder 94 is rotatably connected to the side of the support ear plate 91 through a rotating column, and the piston rod end of the articulated cylinder 94 is connected to the pressing ear plate 93 through a hinge column 92; a pressing wheel 96, a plurality of pressing wheels 96 are rotatably arranged on the outer side of the support ear plate 91 through a rotating column; a driving pulley 97, a servo motor is fixed on the support ear plate 91, and the output shaft of the servo motor passes through the support ear plate 91 to be installed with a driving pulley 97, and the driving pulley 97, the pressing wheel 96 and the guide wheel 95 are in the same plane; a conveyor belt 98, the conveyor belt 98 is connected end to end, and the conveyor belt 98 passes through the presser foot of the cutting and sewing machine 10 and is wound around the driving pulley 97, the pressing wheel 96 and the guide wheel 95;

[0037] When the sliding clamping plate 84 and the fixed clamping plate 85 drive the clamped pulling belt to move to the upper surface of the surrounding fabric, the piston rod of the three-rod telescopic cylinder 78 on the mounting plate 79 extends and the surrounding fabric clamped by the side vertical plate 82 moves toward the end surface of the pressing ear plate 93. At this time, it is necessary to control the piston rod of the articulated cylinder 94 to retract so that it drives the end surface of the pressing ear plate 93 to move upward, thereby causing the pressing wheel 96 rotatably set at the end of the pressing ear plate 93 to detach from the upper surface of the surrounding fabric. When the sliding clamping plate 84 and the fixed clamping plate 85 move to the bottom of the two symmetrically tilted pressing ear plates 93, at this time, the two The clamping wheel 96 on the side of the end of the clamping ear plate 93 and the wound conveyor belt 98 will be aligned with the two U-shaped notches 86 opened on the sliding clamp plate 84, and the front and rear outer sides of the conveyor belt 98 will not contact the side walls of the U-shaped notch 86. At this time, the piston rod of the telescopic cylinder 78 on the side vertical plate 82 is contracted, causing it to move the sliding clamp plate 84 upward a small distance, so that the handle belt is no longer in a clamped state. Then the piston rod of the articulated cylinder 94 is controlled to extend, causing it to push the end surface of the tilted clamping ear plate 93 to move downward, and then the tilted clamping wheel 96 will drive the conveyor belt 98 to be pressed tightly against the upper surface of the handle belt. 8 is driven to rotate by the cooperation of the servo motor, the driving pulley 97 and the plurality of pressure wheels 96 fixed on the support ear plate 91. The rotating conveyor belt 98 can transfer the tightly fitted handle belt from between the sliding clamp plate 84 and the fixed clamp plate 85 to the upper surface of the surrounding fabric under the cooperation of the teeth on its outer surface. Then, the continued rotation of the conveyor belt 98 can not only press the vertical handle belt to fit the surrounding fabric and transport it synchronously, but also because the conveyor belt 98 passes through the presser foot plate of the cutting and sewing machine 10, the conveyor belt 98 will transport the surrounding fabric to the cutting and sewing machine 10 for unnecessary edge cutting, and then the compressed vertical handle belt will be transported to the cutting and sewing machine 10. The handle strap is sewn, so that the pressing and conveying mechanism 9 can not only transfer the clamped handle strap from the clamping component 8 to the surrounding fabric, but also press and convey the vertical handle strap to the cutting and sewing machine 10 to cut the excess surrounding fabric first, thereby improving the accuracy and quality of sewing the handle strap attached to the cut surrounding fabric, and can effectively prevent the excess edge of the surrounding fabric from being skewed during cutting because the handle strap is only placed on the surrounding fabric for conveying but not pressed and conveyed, thereby affecting the sewing accuracy and quality of the mattress handle strap on the surrounding fabric by the all-in-one machine.

[0038] As an embodiment of the present invention, the compression conveying mechanism 9 further includes a tensioning support plate 99, a mounting post 910, a hooked tension spring 911, and a positioning post 912. The tensioning support plate 99 is hingedly connected to the outer side surface of the support ear plate 91 by a hinge post 92. The mounting post 910 is fixed to the inclined upper end surface of the tensioning support plate 99, and a compression wheel 96 is rotatably mounted on the mounting post 910. The upper end hook of the hooked tension spring 911 is hooked on the downwardly inclined end surface of the tensioning support plate 99, and the lower end hook of the hooked tension spring 911 is hooked on the positioning post 912 fixed on the support ear plate 91.

[0039] In the design scheme of the present invention, in order to facilitate the adjustment of the tension of the conveyor belt 98 and to facilitate the conveyor belt 98 to disengage the handle belt clamped on the clamping assembly 8, a tensioning support plate 99 is swingably set on the support ear plate 91 through the hinge column 92, and the conveyor belt 98 can be coiled around the pressure wheel 96 at the end of the positioning column 912. When the conveyor belt 98 drives the compressed handle belt and the surrounding fabric to move, if the position where the handle belt or the surrounding fabric contacts the conveyor belt 98 is uneven and causes the conveyor belt 98 to jump, the conveyor belt 98 can swing at the pressure wheel 96 at the end of the positioning column 912, and then the cooperation of the hook spring 911 at the inclined bottom end of the tensioning support plate 99 and the positioning column 912 can support the tensioning and jumping of the tensioning support plate 99.

[0040] As an embodiment of the present invention, two groups of adjustment mechanisms 11 are provided on the upper surface of the operating table 1, and the two groups of adjustment mechanisms 11 respectively adjust the cutting and sewing machines 10 on both sides of the operating table; in the design scheme of the present invention, the two groups of adjustment mechanisms 11 are respectively connected to the two cutting and sewing machines 10, so that the two groups of adjustment mechanisms 11 can adjust the distance between the two cutting and sewing machines 10, thereby facilitating the cutting and sewing of fabrics of different widths. Since the pressing and conveying mechanism 9 is installed on the body of the cutting and sewing machine 10, when the distance between the two cutting and sewing machines 10 is adjusted, the distance between the pressing and conveying mechanisms 9 will also be adjusted, so that the pressing and conveying mechanism 9 can also perform pressing and conveying guidance on handle straps of different vertical lengths.

[0041] As an embodiment of the present invention, the distance between the two symmetrical pressing lugs 93 is equal to the distance between the two U-shaped notches 86 provided on the sliding clamping plate 84 and the fixed clamping plate 85 in the clamping assembly 8 that cooperates with each other in the handle storage mechanism 6. The width of the pressing wheel 96 is smaller than the width of the U-shaped notch 86. The sliding clamping plate 84 and the fixed clamping plate 85 on the clamping assembly 8 that slides together above the handle storage mechanism 6 are both provided with a notch adjustment assembly 12, and the notch adjustment assembly 12 is used to adjust the distance between the two U-shaped notches 86.

[0042] In the scheme designed by the present invention, when it is necessary to cut and sew the fabrics and handle straps of different widths, the two sets of adjustment mechanisms 11 can adjust the distance between the cutting and sewing machine 10 and the pressing and conveying mechanism 9, and at this time it is also necessary to adjust the distance between the two U-shaped notches 86 opened on the sliding clamping plate 84 and the fixed clamping plate 85, so that the distance between the adjusted pressing ear plates 93 can always be aligned with the two U-shaped notches 86, and then set the notch adjustment components 12 on the sliding clamping plate 84 and the fixed clamping plate 85, so that The slot adjustment assembly 12 can adjust the distance between the two U-shaped slots 86, so that it can continue to cooperate with the clamping wheels 96 and the conveyor belt 98 on the two adjusted clamping ear plates 93, so that handle straps of different vertical lengths can be continuously clamped and transferred to the apron fabric through the clamping assembly 8, and then compressed and transferred to the apron fabric through the adjusted clamping conveying mechanism 9, and then transported to the cutting and sewing machine 10 to cut the excess edges of the apron fabric, and at the same time sew the handle straps and the apron fabric.

[0043] As an embodiment of the present invention, the notch adjustment assembly 12 includes an L-shaped support block 121, a guide slide 122, a T-shaped guide bar 123, a guide support plate 124, a double-headed cylinder 125 and a support block 126; the L-shaped support block 121 is symmetrically slidably arranged on both sides of the splint, and the end face of the horizontal cross block of the L-shaped support is fixed with a guide slide 122, and the upper and lower aligned surfaces of the fixed splint 85 and the sliding splint 84 are provided with a plurality of T-shaped guide grooves 127, and each of the T-shaped guide grooves 127 is symmetrically slidably provided with a T-shaped guide bar 123, and the two T-shaped guide bars 123 close to the side of the side plate 82 are symmetrically The two guide slides 122 are connected, and the fixed splint 85 and the sliding splint 84 are aligned with each other on the upper and lower surfaces and symmetrically slide with guide support plates 124. The symmetrical guide support plates 124 are connected to multiple groups of symmetrical T-shaped guide bars 123 away from the side of the side plate 82. The two double-headed cylinders 125 are respectively fixed on the lower surface of the fixed splint 85 and the upper surface of the sliding splint 84, and the piston rods of the double-headed cylinders 125 are respectively connected to the support blocks 126 fixed on the outer surface of the symmetrical L-shaped support blocks 121. A U-shaped notch 86 is formed between the side surface of the vertical cross block of the L-shaped support block 121 and the side surface of the guide support plate 124.

[0044] When the distance between the two U-shaped notches 86 needs to be reduced, the piston rod of the double-headed cylinder 125 on the upper surface of the sliding splint 84 is simultaneously retracted, so that the two symmetrical support blocks 126 drive the two L-shaped support blocks 121 to move toward the middle position of the mutually sliding splint 84, and at this time the guide slide 122 drives the T-shaped guide bar 123 to slide in the T-shaped guide groove 127 provided on the lower surface of the sliding splint 84, thereby making the cooperation of the T-shaped guide bar 123 and the guide slide 122 play a role in guiding and supporting the sliding of the L-shaped support block 121, and when the two symmetrical guide slides 122 slide close to each other, the guide slide 122 will drive the two symmetrical guide support plates 124 on the lower surface of the sliding splint 84 to slide close to each other, thereby making the L-shaped support block 121 and the guide support plate 1 The U-shaped slots 86 are formed on the vertical cross blocks 121 of the L-shaped support block 121 and the side surfaces of the guide support plate 124. Therefore, the synchronous sliding of the L-shaped support block 121 and the guide support plate 124 will not change the size of the U-shaped slots 86. The synchronous movement of the two sets of symmetrical L-shaped support blocks 121 and the guide support plate 124 toward the middle of the sliding splint 84 can reduce the distance between the two U-shaped slots 86 and adjust the distance between the two U-shaped slots 86 on the fixed splint 85. As a result, the handle belt with a reduced vertical length can be continuously clamped and transferred from the storage frame to the surrounding fabric with the cooperation of the adjusted clamping ear plate 93, the rotating clamping wheel 96 and the conveyor belt 98, and then compressed, transferred and conveyed, so that the all-in-one machine can vertically sew mattress handle belts of different widths to the surrounding fabric.

[0045] As an embodiment of the present invention, the slot adjustment assembly 12 further includes a positioning block 128 and a hexagon socket screw 129. The symmetrical guide support plates 124 and the symmetrical guide slide bars 122 are in contact with each other, and a snap-fit ​​groove is provided on the upper surface of the guide support plates 124 and the guide slide bars 122 where they are in contact. Each of the snap-fit ​​grooves has a threaded hole. The positioning block 128 is slidably inserted into the aligned snap-fit ​​grooves, and the positioning block 128 is fixed to the snap-fit ​​groove by the cooperation of the hexagon socket screw 129 and the threaded hole.

[0046] In the design scheme of the present invention, in order to facilitate the synchronous sliding of the guide support plate 124 and the L-shaped support block 121 without changing the size of the U-shaped groove 86, the present invention provides a locking groove on the upper surface of the guide slide 122 and the guide support plate 124 where they are fitted together. When the symmetrical guide support plate 124 is slid into the T-shaped guide groove 127 provided on the splint through the T-shaped guide bar 123, the locking groove provided on the guide support plate 124 is aligned with the locking groove on the guide slide 122, and then the positioning block 128 is inserted into the two locking grooves, and then the hexagon socket screw 129 is passed through the socket of the positioning block 128 and threadedly connected to the threaded hole, thereby facilitating the connection between the guide support plate 124 and the guide slide 122, so that the guide support plate 124 can fit and support the clamped handle strap.

[0047] Example 2:

[0048] like Figure 7 As shown, as another embodiment of the present invention, a cavity guide bar 13 is fixedly provided in the front-to-back horizontal direction in the middle of the upper and lower aligned surfaces of the fixed clamping plate 85 and the sliding clamping plate 84, and a winding rod 14 is provided in the cavity guide bar 13 to rotate via a torsion spring. Two layers of sealing film 15 are wound around the winding rod 14, and the free end surface of each layer of the sealing film 15 extends out of the cavity guide bar 13 and is connected to the end surface of the symmetrical guide support plate 124, and the upper surface of the sealing film 15 is flush with the upper surface of the guide support plate 124;

[0049] In the scheme designed by the present invention, in order to prevent the two symmetrical guide support plates 124 from being in an empty state, causing the pulling belt clamped between the sliding clamping plate 84 and the fixed clamping plate 85 to bend or the fluff generated by the pulling belt to fall into the T-shaped guide groove 127, thereby affecting the stable sliding of the symmetrical guide support plates 124, the present invention connects the sealing film 15 to the corresponding sides of the two guide support plates 124, and the two sealing films 15 are rolled up in the cavity guide strip 13 in the middle of the clamping plate through the winding rod 14. When the two guide support plates 124 slide away from each other, the sealing film 15 will be rolled up from the winding rod 14 in the cavity guide strip 13. When the two guide plates 124 are released, the torsion spring on the winding rod 14 will be twisted. When the two guide support plates 124 approach each other, the torque generated by the torsion spring on the winding rod 14 will be released, which will drive the winding rod 14 to rotate in the opposite direction, thereby winding the two sealing films 15, so that the two sealing films 15 can be adjusted in length according to the distance between the guide support plates 124, so that the sealing film 15 can not only seal the exposed T-shaped guide groove 127, but also the upper surface of the sealing film 15 is flush with the upper surface of the guide support plate 124, which can support the clamped handle strap and prevent the middle part of the handle strap from bending due to excessive clamping force.
