[0011] Preferably, the outer edges of the connecting columns are fixedly connected with fixing rings, the outer edges of the fixing rings are provided with connecting annular grooves, and the inner cavities of two adjacent connecting annular grooves are jointly sleeved with elastic rings.

[0012] The method for using the stress-free flexible combined fixed structure comprises the following steps:

[0013] S1: Before the device starts working, select the working state of the device. The device can be installed in other equipment for use, and can also be used as an independent device. If the device is installed in other equipment for use, the operator moves the disc, puts the cross rod at the bottom of the disc into the matching groove in other equipment, and installs the device. If the device is used as an independent device, the operator takes out four support columns, and the support columns drive the chassis to move, and move the support columns to the adjacent limiting threaded barrel, and connect the support columns to the limiting threaded barrel through the external thread at the outer edge of the support column near the top, and use the device as an independent device, which increases the scope of application of the device;

[0014] S2: When the device starts working, the operator picks up the flexible part, which is a thin sheet-like object, and passes the flexible part through two adjacent elastic clamps in sequence. There is only a small gap between the two adjacent elastic clamps. When the flexible part passes through the two adjacent elastic clamps, the elastic clamp will be displaced, and the elastic clamp will drive the slider to move. The slider drives the limit spring to compress, and the elastic clamp will drive the connecting swing plate and the limit swing plate to swing through the limit fixing block, so that several elastic clamps clamp and fix the two sides of the flexible part;

[0015] S3: After the two sides of the flexible part are clamped and fixed, the elastic clamp is pushed, and the elastic clamp drives the flexible part to move toward the center of the disc. The elastic clamp drives the vertical plate to move through the slider, and the vertical plate drives the connecting threaded cylinder and the first T-block to move through the fixed threaded rod. The first T-block moves inside the adjacent T-slots, so that the side of the flexible part close to the center of the disc gradually approaches the two adjacent connecting clamps. The limiting threaded rod and the T-plate prevent the first T-block from falling from the T-slot.

[0016] S4: When one side of the flexible part gradually enters between two adjacent connecting splints, the distance between the connecting splints is adjusted by adjusting the size of the elastic ring, and the elastic ring is put on the surface of the two adjacent fixed rings. The elasticity of the elastic ring drives the upper and lower connecting columns to gradually approach each other. When the connecting columns gradually approach each other, they will drive the cross plate to move, and the cross plate drives the connecting spring to stretch. Then the connecting column drives the connecting splint to move through the cross bar, and the upper and lower connecting splints clamp the flexible part. The position of the connecting splint can be adjusted not only up and down, but also laterally. Pull the connecting splint, the connecting splint drives the cross bar to move, and the cross bar drives the protrusion to move in the groove inside the connecting column, thereby changing the position of the connecting splint.

[0017] S5: After completing steps S2-S4, the flexible parts need to be processed. When processing the flexible parts, a variety of different processing equipment will be used. The processing equipment with an external threaded rod is moved to one end of the adjacent L-shaped column, and the threaded rod outside the processing equipment is rotated to the threaded hole at one end of the L-shaped column, so that different processing equipment can be installed. The position of the processing equipment can also be adjusted. The operator pulls the L-shaped column, and the L-shaped column drives the telescopic hollow column to stretch. The telescopic hollow column drives the support rod to move, and the support rod is in the hole inside the limit L-shaped rod. The movement can provide preliminary support for the L-shaped column and the processing equipment. The elastic arc plate and the connecting L-shaped rod can further support the L-shaped column and the processing equipment, so that the processing equipment can perform processing at different positions of the flexible parts. After the processing is completed, the processing equipment is taken out and can be placed in one of the triangular frames. Tools, flexible parts and sundries can also be placed in adjacent triangular frames. The triangular frames are installed and disassembled through the fixed plates. The connecting threaded rods are rotated and taken out from the fixed columns. The L-shaped columns, telescopic hollow columns and limit L-shaped rods can be disassembled.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention can realize that the device can be installed in other equipment and used as an independent device through the mutual cooperation between the disc, the ring, the telescopic hollow column, the L-shaped column and other structures. When installed in other equipment, the cross rod is inserted into the groove matching with the other equipment. When used as an independent device, the support column is installed inside the limit threaded cylinder, and the chassis is in contact with the ground, so that it can be used normally. The threaded hole at one end of the L-shaped column is convenient for installation of different processing equipment. The L-shaped column is moved, and the L-shaped column drives the telescopic hollow column to move, which can adjust the position of the processing equipment, facilitate the processing of different positions of the flexible parts, and the tools, flexible parts and sundries can be placed inside different triangular frames, and the triangular frames can be taken out from the inside of the disc;

[0020] Through the mutual cooperation among the elastic splint, the connecting splint, the cross plate, the first T-block and other structures, the elastic splint can be moved laterally through the first T-block, and at the same time the elastic splint can be moved vertically through the slider, so that the flexible part passes through the adjacent left and right elastic splints. The elastic splint clamps the flexible part under the action of the limit spring and the connecting swing plate and the limit swing plate, while the connecting splint clamps and fixes the flexible part through elastic rings of different sizes, thereby ensuring the flatness of the surface of the flexible part during the fixing process.

A connecting spring 16 is fixedly connected to one side of the cross plate 15, and the end of the connecting spring 16 away from the cross plate 15 is fixedly connected to the side of the adjacent cross groove.

[0045] The elastic clamp 21 moves laterally through the first T-block 20, and at the same time moves vertically through the slider 30, so that the flexible part passes through the adjacent elastic clamps 21 on the left and right sides. The elastic clamp 21 clamps the flexible part through the limit spring 31 and the connecting swing plate 27 and the limit swing plate 28, while the connecting clamp 17 clamps and fixes the flexible part through elastic rings 40 of different sizes, thereby ensuring the flatness of the surface of the flexible part during the fixing process.

[0046] The method for using the stress-free flexible combined fixed structure comprises the following steps:

[0047] S1: Before the device starts working, select the working state of the device. The device can be installed in other equipment for use, and can also be used as an independent device. If the device is installed in other equipment for use, the operator moves the disc 1, puts the cross rod 7 at the bottom of the disc 1 into the groove matching it in other equipment, and installs the device. If the device is used as an independent device, the operator takes out four support columns 3, and the support columns 3 drive the chassis 4 to move, and moves the support columns 3 to the adjacent limiting threaded cylinder 35. The support columns 3 are connected to the limiting threaded cylinder 35 through the external threads at the outer edge of the support columns 3 near the top, and the device is used as an independent device, which improves the application range of the device;

[0048] S2: When the device starts working, the operator picks up the flexible part, which is a thin sheet-like object, and passes the flexible part through two adjacent elastic clamps 21 in sequence. There is only a small gap between the two adjacent elastic clamps 21. When the flexible part passes through the two adjacent elastic clamps 21, the elastic clamps 21 will be displaced, and the elastic clamps 21 will drive the slider 30 to move. The slider 30 drives the limit spring 31 to be compressed, and the elastic clamps 21 will drive the connecting swing plate 27 and the limit swing plate 28 to swing through the limit fixing block 29, so that a plurality of elastic clamps 21 clamp and fix the two sides of the flexible part;

[0049] S3: After the two sides of the flexible part are clamped and fixed, the elastic clamping plate 21 is pushed, and the elastic clamping plate 21 drives the flexible part to move toward the center of the disc 1. The elastic clamping plate 21 drives the vertical plate 22 to move through the slider 30. The vertical plate 22 drives the connecting threaded cylinder 23 and the first T-block 20 to move through the fixed threaded rod 24. The first T-block 20 moves inside the adjacent T-slots, so that the side of the flexible part close to the center of the disc 1 gradually approaches the two adjacent connecting clamping plates 17. The limiting threaded rod 18 and the T-plate 19 prevent the first T-block 20 from falling from the T-slot.

[0050] S4: When one side of the flexible part gradually enters between two adjacent connecting splints 17, the distance between the connecting splints 17 is adjusted by adjusting the size of the elastic ring 40, and the elastic ring 40 is put on the surface of the two adjacent fixing rings 39. The elasticity of the elastic ring 40 drives the upper and lower connecting columns 38 to gradually approach each other. When the connecting columns 38 gradually approach each other, they will drive the cross plate 15 to move, and the cross plate 15 drives the connecting spring 16 to stretch. Then the connecting column 38 drives the connecting splint 17 to move through the cross bar 36, and the upper and lower connecting splints 17 clamp the flexible part. The position of the connecting splint 17 can be adjusted not only up and down, but also laterally. Pull the connecting splint 17, and the connecting splint 17 drives the cross bar 36 to move. The cross bar 36 drives the protrusion 37 to move in the groove inside the connecting column 38, thereby changing the position of the connecting splint 17.

[0051] S5: After completing steps S2-S4, the flexible parts need to be processed. When processing the flexible parts, a variety of different processing equipment will be used. The processing equipment with an external threaded rod is moved to one end of the adjacent L-shaped column 13, and the threaded rod outside the processing equipment is rotated to the threaded hole at one end of the L-shaped column 13, so that different processing equipment can be installed. The position of the processing equipment can also be adjusted. The operator pulls the L-shaped column 13, and the L-shaped column 13 drives the telescopic hollow column 12 to stretch. The telescopic hollow column 12 drives the support rod 14 to move, and the support rod 14 moves in the hole inside the limit L-shaped rod 11 , can provide preliminary support for the L-shaped column 13 and the processing equipment, the elastic arc plate 9 and the connecting L-shaped rod 8 can further support the L-shaped column 13 and the processing equipment, so that the processing equipment can process at different positions of the flexible parts. After the processing is completed, the processing equipment is taken out and can be placed inside one of the triangular frames 5, and tools, flexible parts and sundries can also be placed in adjacent triangular frames 5. The triangular frame 5 is installed and disassembled through the fixing plate 33, and the connecting threaded rod 10 is rotated and taken out from the inside of the fixing column 6, and the L-shaped column 13, the telescopic hollow column 12 and the limiting L-shaped rod 11 can be disassembled.

[0052] Working principle: before the device starts working, the working state of the device is selected. The device can be installed in other equipment for use, and can also be used as an independent device. If the device is installed in other equipment for use, the operator moves the disc 1, puts the cross rod 7 at the bottom of the disc 1 into the groove that matches it in other equipment, and installs the device. If the device is used as an independent device, the operator takes out four support columns 3, and the support columns 3 drive the chassis 4 to move, and move the support columns 3 to the adjacent limiting threaded cylinder 35. The support columns 3 are connected to the limiting threaded cylinder 35 through the external threads at the outer edge of the support columns 3 near the top, and the device is used as an independent device, which improves the scope of application of the device.

[0053] When the device starts working, the operator picks up the flexible part, which is a thin sheet-like object, and passes the flexible part through two adjacent elastic splints 21 in sequence. There is only a small gap between the two adjacent elastic splints 21. When the flexible part passes through the two adjacent elastic splints 21, the elastic splint 21 will be displaced, and the elastic splint 21 will drive the slider 30 to move. The slider 30 drives the limit spring 31 to be compressed. The elastic splint 21 will drive the connecting swing plate 27 and the limit swing plate 28 to swing through the limit fixing block 29, so that several elastic splints 21 clamp and fix the two sides of the flexible part. After the two sides of the flexible part are clamped and fixed, the elastic splint 21 is pushed, and the elastic splint 21 drives the flexible part to move toward the center of the disc 1.
