It is used to clamp and fasten the data line or power line. The inside of the fastening nut is arranged in a reverse funnel with a larger bottom and a smaller top. In this way, when the fastening nut is rotated downward, the fastening spring piece can be squeezed inward, thereby clamping and fastening the data line or power line, so that after the storage is completed, the data line or power line can be fixed and will not be pulled out by external force.

[0032] Embodiment 3

[0033] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0034] The two sides of the bottom end of the mounting frame 402 are provided with a resistance mechanism 11, which includes a support rod 1101, which is fixedly mounted on one side of the bottom end of the mounting frame 402, a connecting rod 1102 is fixedly mounted on the outer wall of the axial end of the support rod 1101, a telescopic spring 1103 is embedded in the interior of the connecting rod 1102, a penetration rod 1104 is penetrated from the interior of the connecting rod 1102, and the resistance mechanism 11 also includes a fixing frame 1105, which is fixed on the top of the penetration rod 1104, and a resistance wheel 1106 is rotatably connected to the interior of the fixing frame 1105; The axial end of the support rod 1101 is located between the two limit plates 9. The connecting rod 1102 fixed by the support rod 1101 is elastically pushed by the telescopic spring 1103 to stably slide the passing rod 1104 along the connecting rod 1102, so that the fixing frame 1105 can drive the two resistance wheels 1106 to resist the wound cable. The elastic push of the telescopic spring 1103 can make the resistance wheels 1106 press on the cable, so that the cable is compressed to avoid looseness, which causes the cable to loosen inside the storage shell 2, thereby causing shaking or even entanglement.

[0035] Working principle: The display terminal 1 is used to store and place cables through the storage shell 2 on one side, and the driving rod 8 is rotated by the rotating adjustment block 7, so that the cables are retracted and released through the threading hole 3, and the two limit plates 9 with increased inner diameters are convenient for limiting the folding and rotation of a single cable to avoid entanglement. The rotation block 401 is manually adjusted to rotate, so that the threaded rod group 403 is rotated. The threaded rod group 403 is composed of two bidirectional threaded rods fixed to each other, which can allow the two corresponding clamping plates 404 to slide relative to or away from each other along the mounting frame 402 through the sliding engagement guide groove 405, so that the damping spring 406 elastically pushes the receiving frame 407, so that the corresponding two receiving frames 407 respectively rotate the connected concave wheels 408 and cams 409 to limit and clamp the cables to prevent loosening, or adjust the rotating block 401 to create a gap between the concave wheels 408 and the cams 409, which is convenient for pulling or winding up the cables. The receiving frame 407 slides stably along the guide groove 405 through the slider 6 on one side and the slider 6 on the other side of the fixed connecting plate 5, so as to avoid excessive clamping and bending of the damping spring 406, which will affect the stability of the receiving frame 407. The fixed block 1001 at the top of the connecting plate 5 can slide into and engage the card block 1003 through the limiting groove 1002, and then be fixed and installed with the fixed block 1001 by bolts. The sponge 1004 bonded to the card block 1003 can clamp the cable and clean the outer wall of the sliding cable, and it is convenient to replace it regularly. The support rod 1101 is fixed by the mounting frame 402 and axially inserted between the two limiting plates 9. The telescopic spring 1103 embedded in the connecting rod 1102 elastically pushes the rod 1104, so that the fixed frame 1105 drives the two contact wheels 1106 to contact when the cable is rolled up, so as to avoid looseness, looseness or even entanglement.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
