The outer ends of the three screw rods 604 are movably sleeved with a fixed seat 605, and the fixed seat 605 is connected to the side wall of the first baffle 602. The outer ends of the three screw rods 604 are all threadedly sleeved with a movable seat 606, and the inside of the two sides of the movable seat 606 is penetrated by a sliding rod 625, and the two ends of the sliding rod 625 are respectively connected to the first baffle The plate 602 is connected to the second baffle plate 603, the upper end of the movable seat 606 is rotatably connected to the first connecting rod 607, the upper part of the first connecting rod 607 is rotatably connected to the extension plate 608, the lower end of the extension plate 608 is circumferentially distributed with connecting frames 609 at equal angles, the first connecting rod 607 is rotatably connected to the connecting frame 609, a side wall of the connecting frame 609 is provided with a long groove 610, the upper end of the fixed seat 605 is rotatably connected to the second connecting rod 611, the second connecting rod 611 is rotatably connected to the middle intersection of the first connecting rod 607, the upper part of the second connecting rod 611 is connected to the sliding pin 612, and the sliding pin 612 is slidably connected to the long groove 610;

[0032] The three extension plates 608 are connected to one side with a crimping piece 613, and the crimping piece 613 includes two fixing plates 6131 connected to the side ends of the extension plates 608, and the lower ends of the two fixing plates 6131 are connected to a T-shaped rod 6132, and the outside of the T-shaped rod 6132 is movably sleeved with a mounting plate 6133, and the lower end of the mounting plate 6133 is connected to a U-shaped frame 6134, and the U-shaped frame 6134 is movably sleeved outside the T-shaped rod 6132, and the middle part of the lower end of the U-shaped frame 6134 is connected to a clamping block 6135;

[0034] By tightening or loosening the butterfly nut 6138, the adjustment plate 6137 can slide along the outside of the T-bar 6132, so that the distance between the adjustment plate 6137 and the mounting plate 6133 can be adjusted;

[0035] When the distance between the adjustment plate 6137 and the mounting plate 6133 becomes smaller, the elastic force of the first spring 6139 increases; conversely, when the distance between the two increases, the elastic force of the first spring 6139 decreases, thereby being able to control the force of the elastic compression;

[0036] One side of the U-shaped frame 6134 is connected to an ear plate seat 61310, and a swing plate 61311 is rotatably connected inside the ear plate seat 61310. An arc-shaped abutment head 61312 is provided at the lower end of the swing plate 61311, and a connecting plate 61313 is connected to the upper end of the swing plate 61311. A second spring 61314 is connected between the connecting plate 61313 and the U-shaped frame 6134;

[0037] One end of each of the three screw rods 604 extends to one side of the second baffle 603 and is connected to a transmission gear 614, wherein an extended section of one of the screw rods 604 is connected to a handle 615, and a transmission gear ring 616 is provided inside the three transmission gears 614, and the transmission gear ring 616 is rotatably connected to the cylinder 601 through a bearing, and the transmission gear ring 616 is meshedly connected to the three transmission gears 614;

[0038] The first baffle plate 602 is provided with mounting screws 617 distributed at equal angles on its circumference. The mounting screws 617 penetrate the first baffle plate 602 and are threadedly connected to the top wall of the cable chamber 3. A rotating block 618 is connected to one end of the mounting screw 617. First locking nuts 619 are threadedly sleeved on the outside of the mounting screw 617 and located on both sides of the first baffle plate 602. The two first locking nuts 619 are in contact with the two side walls of the first baffle plate 602 respectively. A second locking nut 620 is threadedly sleeved on one side of the outside of the mounting screw 617 near the end, and the second locking nut 620 is in contact with the top wall of the cable chamber 3.

[0039] A positioning block 621 is fixedly connected to one side of the second baffle 603, and a pull rod 622 is movably passed through the interior of the positioning block 621. One end of the pull rod 622 is connected to an arc-shaped tooth plate 623, which engages with the transmission gear ring 616. A third spring 624 is sleeved on the outside of the pull rod 622, and one end of the third spring 624 is connected to the positioning block 621, and the other end of the third spring 624 is connected to the arc-shaped tooth plate 623.

[0040] Working principle: When in use, the access cable passes through the cylinder 601 in the fastening mechanism 6 and comes out from the other end, so that the access cable is plugged into the cable connector 5;

[0041] The handle 615 is rotated to drive the screw rod 604 connected thereto to rotate, and the screw rod 604 drives the other two screw rods 604 to rotate synchronously through the meshing action of the transmission gear 614 and the transmission gear ring 616. As the screw rod 604 rotates, the movable seat 606 moves along the thread direction on the screw rod 604;

[0042] The movement of the movable seat 606 drives the extension plate 608 to move through the first connecting rod 607. At the same time, the sliding pin 612 on the second connecting rod 611 slides in the long slot 610 of the connecting frame 609. The first connecting rod 607 and the second connecting rod 611 perform cross motion around their connection intersection to ensure the smooth movement of the extension plate 608. At this time, the three extension plates 608 gradually shrink toward the cylinder 601.

[0043] The movement of the three extension plates 608 drives the three crimping members 613 to gradually approach the center direction until the clamping block 6135 contacts the outside of the access cable, and then continues to drive the three crimping members 613 to approach and contract, so that the clamping block 6135 drives the U-shaped frame 6134 to press against the mounting plate 6133 outward, thereby generating a pressing force on the first spring 6139. Under the action of the spring force of the first spring 6139, the clamping block 6135 has a pressing force toward one side of the access cable, so as to clamp the access cable;

[0044] On the other hand, when the clamp block 6135 clamps the access cable, under the action of the second spring 61314, the second spring 61314 pushes the connecting plate 61313 to drive the swing plate 61311 to rotate around the ear plate seat 61310, so that the arcuate abutment 61312 keeps in contact with the access cable. Since the arcuate abutment 61312 is always in contact with the access cable and its contact surface is an arc-shaped structure, even if the access cable is subjected to external force, when the access cable moves outward, a mutual squeezing force is generated between the arcuate abutment 61312 and the access cable, and the arcuate abutment 61312 can effectively prevent the access cable from loosening and detaching.

[0045] When the predetermined tightening position is reached, the handle 615 stops rotating, all the screw rods 604 stop rotating, the movable seat 606 and the extension plate 608 remain at the current position, and the crimping piece 613 stably clamps the incoming cable. At this time, the arc-shaped tooth plate 623 can be engaged with the transmission gear ring 616, and the third spring 624 provides a holding force to keep the mechanism stable.

[0046] When unlocking is required, pull the pull rod 622 to separate the arc-shaped tooth plate 623 from the transmission gear ring 616, and the normal rotation function of the screw rod 604 can be restored. By rotating the handle 615, the three extension plates 608 are driven to gradually extend, and then the three crimping parts 613 are separated from the access cable. After that, the access cable and the cable connector 5 can be unplugged to remove it.
