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

[0019] 1. When the cable is inserted into the cavity of the fixed frame head for fixing, the present invention applies torque to the outside of the cable end by twisting the fixing mechanism, further increasing the friction and firmness during contact and extrusion, and can increase the extrusion force with the outer end of the cable by extrusion and fixation at multiple positions, thereby improving the firmness of the cable when fixed, and if one of the extrusion forces is insufficient, it can also be fixed by extrusion at other positions.

[0020] 2. The present invention activates the fitting and fixing mechanism through the fastening mechanism, further improving the firmness of the cable when being fixed, and increases the firmness of the cable when being fixed by squeezing and fixing the cable end around it, and can also increase the fitting force with the outside of the cable, avoiding short-circuit damage to the circuit of the fixed frame head caused by external liquid water flowing into the inside of the fixed frame head, thereby improving the stability of the cable when being fixed.

[0021] 3. The present invention triggers the loosening limit mechanism and the buffer limit mechanism through the fastening mechanism.

[0036] like Figure 1 As shown, the multiple fixed frame heads 10 involved in the present invention are movably installed on the front and rear sides of the fixed rod 2, and a docking circular opening 3 is opened in the middle of the right side of each fixed frame head 10. A cavity is provided inside each fixed frame head 10, and the cavity is connected to the outside through the docking circular opening 3. Frame covers 14 are installed in the middle of the top end and the middle of the bottom end of the fixed frame head 10.

[0037] like Figure 1 , Figure 2As shown, the height adjustment mechanism 4 involved in the present invention includes an adjustment slot 401, and the adjustment slots 401 are opened on the front and rear sides of the fixed rod 2. A plurality of fixed frame heads 10 are slidably connected in each adjustment slot 401, and an adjustment slider 407 is provided in the middle of one side of each fixed frame head 10, and the adjustment slider 407 is slidably connected to the adjustment slot 401.

[0038] In this embodiment, a plurality of limit openings 402 are equidistantly provided on the right side of the fixed rod 2, and the plurality of limit openings 402 are connected to the adjusting slide groove 401, a limit recess 406 is provided in the middle of the right side of each adjusting slider 407, each limit recess 406 corresponds to the position of a limit opening 402, an operating limit block 403 is embedded and installed in the limit recess 406 and a limit opening 402, an adjusting slot 404 is provided in the middle of each adjusting slider 407, an adjusting mounting rod 405 with a T-shaped structure is installed on one side of each fixed frame head 10, and the horizontal portion of the adjusting mounting rod 405 with a T-shaped structure is made of soft material, and each adjusting mounting rod 405 is slidably connected to the inside of an adjusting slot 404.

[0039] Among them, Figure 2 As shown, an operating ring is installed on the right end of the operating limit block 403, and a rubber layer is provided on the right side of the outside of the operating limit block 403 through an adhesive sleeve.

[0040] The specific implementation method is as follows: when adjusting the height of the cable fixed docking, the operating limit block 403 is pulled out from the limiting recess 406 and the limiting opening 402, so that the adjusting slider 407 loses its restraining force, and then the fixed frame head 10 is moved, and the adjusting slider 407 is driven by the fixed frame head 10 to slide inside the adjusting slide groove 401. When it moves to a suitable position, the operating limit block 403 is pressed to make it fit into the limiting opening 402 and the limiting recess 406. The slider 407 and the fixed frame head 10 are limited and fixed; when the operation limit block 403 is fitted into the limit recess 406, the rubber layer is located between the limit opening 402 and the operation limit block 403, and the limit opening 402 and the operation limit block 403 will squeeze the rubber layer, thereby increasing the firmness of the operation limit block 403 when it is fitted and installed; the operation ring provided on the right side of the operation limit block 403 can facilitate the removal of the operation limit block 403 from the limit recess 406 and the limit opening 402.

[0041] When it is necessary to fine-tune the horizontal position of the fixed frame head 10, the fixed frame head 10 is pulled to drive the adjusting mounting rod 405 to move inside the adjusting slot 404, so that the horizontal position of the fixed frame head 10 can be adjusted. At the same time, the adjusting mounting rod 405 of the T-shaped structure can prevent it from moving out of the adjusting slot 404, and the adjusting mounting rod 405 made of soft material can be more conveniently inserted into the adjusting slot 404, thereby increasing the convenience when fixing the cable, and avoiding the situation that the fixed frame head 10 cannot be adjusted horizontally alone during fixing, resulting in a gap when the cable is installed, and then the cable is not fixed firmly enough. When the twisting fixing mechanism 5, the fitting fixing mechanism 6, the tightening mechanism 7, the loosening limiting mechanism 8 or the buffer limiting mechanism 9 inside the fixed frame head 10 needs to be repaired, replaced or restored to the original state, it is only necessary to open the frame cover 14 at the middle of the top or the middle of the bottom of the fixed frame head 10 to repair, replace or reset its internal parts.

[0043] In this embodiment, each torsion fixing mechanism 5 further includes a single-phase motor 501, a reset spring 506, a limit extrusion block 508, an arc-shaped push groove 510, a reset spring rod 511, a mounting top block 512, a second recess 513 and a pressure controller 514. The single-phase motor 501 is mounted on the left middle part of the fixed frame head 10 through a mounting seat. The single-phase motor 501 is electrically connected to the control panel. The output shaft of the single-phase motor 501 is mounted with a rotating disk 502. A pressure touch switch 15 is mounted in the middle of the right side of the rotating disk 502. The pressure touch switch 15 is electrically connected to the single-phase motor 501. A docking disk 11 is mounted at one end of the pressure touch switch 15, and the pressure touch switch 15 is mounted on the outside. There is a rubber sleeve, and a number of hard rubber docking rods 12 are installed in a circular shape and equidistantly on the right side of the docking plate 11; a number of arc-shaped push grooves 510 are opened in a circular shape and equidistantly on the right side of the rotating disk 502, and a moving long groove is opened on the left side of the moving groove 507. One end of the connecting slider 504 passes through the moving long groove and is slidably connected to the arc-shaped push groove 510, and the connecting slider 504 is a cylindrical structure; the moving slide bar 505 is a T-shaped structure, and a limiting extrusion block 508 is installed at one end of the moving slide bar 505. A reset spring 506 is installed on the outside of the moving slide bar 505, one end of the reset spring 506 is connected to the moving slide bar 505, and the other end of the reset spring 506 is connected to the inner wall of the moving groove 507.

[0044] Among them, Figure 7 As shown, a second recess 513 is provided at one end of each movable slide bar 505, a mounting top block 512 is installed in the middle of the side where the limiting extrusion block 508 is connected to the movable slide bar 505, one end of the mounting top block 512 is slidably connected to the second recess 513, a pressure controller 514 is installed on the inner side of the second recess 513, the pressure controller 514 is electrically connected to the alarm, and reset spring rods 511 are installed around the outside of the mounting top block 512, and the two ends of the reset spring rod 511 are respectively connected to the movable slide bar 505 and the outside of the limiting extrusion block 508.

[0045] In this embodiment, the mounting top block 512 and the movable slide rod 505 are both T-shaped structures, and the horizontal portion of the mounting top block 512 with the T-shaped structure is made of soft material, and the reset spring rod 511 is made of spring steel.

[0046] The specific implementation method is as follows: when fixing the cable, one end of the cable is pressed to pass through the docking circular mouth 3 and move into the cavity of the fixed frame head 10, so that the end of the cable passes through the rotating ring 503 and contacts the docking disk 11, and the cable and the docking plug rod 12 are plugged in. When the docking plug rod 12 clamps the cable end, the contact between the docking plug rod 12 and the insulating layer of the cable end can increase the friction between the docking disk 11 and the rotating disk 502 and the cable end; when the cable docking disk 11 applies an extrusion force, the docking disk 11 squeezes the pressure touch switch 15, thereby triggering the pressure touch switch 15, and starting the single-phase motor 501 through the pressure touch switch 15. The single-phase motor 501 drives the rotating disk 502 to rotate, and drives the docking disk 11 and the docking plug rod 12 to rotate. The docking disk 11 and the docking plug rod 12 drive the end of the cable to twist, so that torque is generated on the outside of the cable end; Figure 5 , Figure 6 As shown, when the single-phase motor 501 drives the rotating disk 502 to rotate clockwise, the connecting slider 504 is driven to move through the clockwise rotating arc-shaped pushing groove 510, and the connecting slider 504 drives the moving slide bar 505 to move toward the cable side. When the moving slide bar 505 moves, it will also drive the limiting extrusion block 508 to move, so that the limiting extrusion block 508 contacts and squeezes the outside of the cable.

[0047] When the limiting extrusion block 508 is extruded against the outside of the cable, the single-phase motor 501 continues to drive the rotating disk 502 to rotate clockwise, and the arc-shaped pushing groove 510 opened on the rotating disk 502 drives the connecting slider 504 and the movable slide bar 505 to continue to move toward one side of the cable, so that the limiting extrusion block 508 pushes the installation top block 512 to move inside the second recess 513, so that the installation top block 512 is in contact with the outside of the pressure controller 514 for extrusion. When the extrusion force reaches the expected value, the alarm will be activated through the pressure controller 514 to tell the staff that the pressure during fixation has reached the expected value. When the cable end is loose, the pressure controller 514 will not be triggered due to insufficient extrusion force, and the alarm cannot be activated to let the staff know that the cable end is loose.

[0048] When the limiting extrusion block 508 pushes the installation top block 512 to move toward the inside of the second recess 513, the reset spring rod 511 is compressed. When the limiting extrusion block 508 contacts the outside of the cable, the torque on the outside of the cable end is used to further increase the friction and firmness during contact extrusion. In addition, through extrusion and fixation at multiple positions, the extrusion force on the external end of the cable can be increased, thereby improving the firmness of the cable when fixed. If one of the extrusion forces is insufficient, the extrusion and fixation at other positions can also be used to fix the cable. Moreover, the operation is faster and no unnecessary operations are required, thereby avoiding the situation where the operation is cumbersome and not quick enough during fixation, or the fixation is performed only at one fixed end. If an unexpected situation occurs at the fixed end, the fixation fails and the cable is detached.

[0049] The T-shaped mounting top block 512 can be prevented from being moved out of the second recess 513, and the horizontal portion of the mounting top block 512 made of soft material can be more conveniently inserted into the second recess 513; the spring steel material increases the elasticity and life of the reset spring rod 511 during use.

[0051] In this embodiment, each fitting and fixing mechanism 6 also includes a conveying airbag 604 and a movable extrusion plate 605. The conveying airbag 604 is installed on the outside of the mounting ring groove 603. One end of the conveying airbag 604 is connected to the extrusion airbag 602, and an air hole is opened between the conveying airbag 604 and the extrusion airbag 602. A movable extrusion plate 605 is installed on the other end of the conveying airbag 604. The side of the movable extrusion plate 605 away from the conveying airbag 604 is connected to the right end of the limiting lever 701 through a hinge. A stable slide rail is installed on the right side of the outside of the mounting ring frame 601, and the movable extrusion plate 605 is guided by the stable slide rail.

[0052] The fastening mechanism 7 involved in the present invention is provided with a plurality of fastening mechanisms 7, each of which is provided with a plurality of fastening mechanisms 7 inside the fixed frame head 10, and the plurality of fastening mechanisms 7 are evenly distributed in the circumferential direction and arranged in the cavity of the fixed frame head 10; each fastening mechanism 7 includes a limit lever 701, a fixed shaft frame 702, a compression spring 703, an extrusion limit block 704 and a movable mounting rod 705, each fixed shaft frame 702 is installed on the right side of the internal cavity of the fixed frame head 10, and one end of each fixed shaft frame 702 is connected to the fixed frame head 10. The inner wall of the fixed frame head 10 is connected, one end of each fixed shaft frame 702 is installed with a limit lever 701 through a rebound hinge, one end of each limit lever 701 is installed with a movable mounting rod 705, one end of each movable mounting rod 705 is installed with an extrusion limit block 704 through a hinge, one end of each limit lever 701 is installed with a compression spring 703, the compression spring 703 is always in a compressed state, and one end of each compression spring 703 is fixedly connected to the inner wall of the fixed frame head 10.

[0053] In this embodiment, a rubber layer is installed on one side of the extrusion limit block 704, and each extrusion limit block 704 is placed at an angle.

[0054] The specific implementation method is as follows: when the end of the cable extends into the cavity of the fixed frame head 10, the end of the cable passes through the extrusion limit block 704, causing the inclined extrusion limit block 704 to rotate around the connection between it and the movable installation rod 705, and at the same time driving the movable installation rod 705 and the limit lever 701 to rotate around one end of the fixed shaft frame 702, and finally making the extrusion limit block 704 horizontal. When the limit lever 701 rotates, it will squeeze the compression spring 703, and the compression spring 703 will be pressed. The reaction force increases the extrusion force between the extrusion limit block 704 and the outside of the cable, thereby improving the firmness of the cable when fixed, and by extruding and fixing the cable end around, the firmness of the fixation is increased; after the cable passes through the extrusion limit block 704, it continues to move toward the inside of the fixed frame head 10, which will cause the extrusion limit block 704 to be subjected to friction. Under the influence of the friction, the extrusion limit block 704 moves toward the inside of the fixed frame head 10, and at the same time, the extrusion limit block 704 drives the movable installation rod 705 to move toward the inside of the fixed frame head 10.

[0055] When the extrusion limit block 704 gradually rotates to a horizontal state, it drives the limit lever 701 to rotate around one end of the fixed axis frame 702, thereby causing the right end of the limit lever 701 to move toward the side of the mounting ring frame 601, that is, the limit lever 701 drives the movable extrusion plate 605 to move toward the side of the mounting ring frame 601. When the limit lever 701 pushes the movable extrusion plate 605 to move, the conveying airbag 604 is squeezed, and the air inside the conveying airbag 604 is transported to the inside of the extrusion airbag 602 through the air hole, so that the extrusion airbag 602 expands and extends out from the inside of the mounting ring frame 601, thereby causing one side of the extrusion airbag 602 to contact and squeeze the outside of the cable, thereby increasing the fitting force between the extrusion airbag 602 and the outside of the cable, thereby increasing the firmness of the cable fixation and improving the stability of the cable when fixed.

The limit needle rod 803 has a T-shaped structure, and the horizontal part of the limit needle rod 803 with a T-shaped structure is made of soft material. The outer sleeve of the limit needle rod 803 is provided with a pulling spring 804, one end of the pulling spring 804 is connected to the horizontal part of the limit needle rod 803, and the other end of the pulling spring 804 is connected to the inner wall of the fixed cylinder 801; when the limit needle rod 803 is all located When inside the fixed cylinder 801, the pulling spring 804 is in a stretched state, and the pulling spring 804 is made of spring steel; a movable limiting plate 806 is movably provided on one side of the movable opening, and a mounting sleeve 808 is installed on the left side of the movable opening, the left end of the movable limiting plate 806 is slidably connected with the inside of the mounting sleeve 808, and a limiting elastic rope 802 is installed in the middle of the left side of the movable limiting plate 806, and one end of the limiting elastic rope 802 is connected to the right end of the extrusion limiting block 704; a stopper 807 is installed at one end of the right side of the movable limiting plate 806, and a limiting hook rod 809 is installed at the end of the mounting sleeve 808 away from the fixed cylinder 801, and the right side of the limiting hook rod 809 is an inclined structure, and the position of the limiting hook rod 809 corresponds to that of the stopper 807.

[0058] like Figure 4 , Fig. 9 As shown, the buffering and limiting mechanisms 9 involved in the present invention are provided in plurality, each fastening mechanism 7 is provided with a buffering and limiting mechanism 9, each buffering and limiting mechanism 9 includes a first notch 901, and each first notch 901 is opened at one end of the limiting lever 701 corresponding thereto.

[0059] In this embodiment, each of the buffer limit mechanisms 9 also includes a buffer spring 902, a movable connecting rod 903, a starting notch 904, an installation spring 905, a movable guide block 906 and a movable partition 907. A movable connecting rod 903 is slidably installed inside the first notch 901, and one end of the movable connecting rod 903 is connected to the movable installation rod 705; the movable connecting rod 903 is in a T-shaped structure, and the horizontal part of the movable connecting rod 903 in the T-shaped structure is made of soft material, and a buffer spring 902 is sleeved on the outside of the movable connecting rod 903, one end of the buffer spring 902 is connected to the horizontal part of the movable connecting rod 903, and the other end of the buffer spring 902 is connected to the inner wall of the first notch 901; the first notch 901 is away from the movable installation rod 905. A starting slot 904 is provided on one side of the mounting rod 705, and a movable partition 907 is installed on one side of the horizontal part of the movable connecting rod 903. The movable partition 907 is located in the middle of the starting slot 904, and mounting springs 905 are installed on opposite sides of the starting slot 904. Movable guide blocks 906 in the form of right-angled trapezoids are installed on opposite ends of the mounting springs 905 on both sides. When the two movable guide blocks 906 contact each other, their inclined surfaces form a V shape, and the movable partition 907 is located between the V-shaped inclined surfaces formed by the two movable guide blocks 906; one of the movable guide blocks 906 is electrically connected to the battery, and the other movable guide block 906 is electrically connected to the fixed electromagnetic block 805, and the battery is electrically connected to the fixed electromagnetic block 805.

[0060] The specific implementation method is as follows: when the cable squeezes and rotates the extrusion limit block 704 to a horizontal state, the cable continues to be pushed so that the extrusion limit block 704 moves under the action of friction, which will cause the extrusion limit block 704 to move to the side away from the movable mounting rod 705, and the extrusion limit block 704 drives the limit elastic rope 802 to move and stretch, and the limit elastic rope 802 drives the movable limit plate 806 to move, so that the movable limit plate 806 is separated from the movable opening, and the movable opening is opened; when the limit elastic rope 802 pulls the movable limit plate 806 to move to the left, the stop block 807 at one end of the movable limit plate 806 is engaged with the inside of the limit hook rod 809, and the limit hook rod 809 fixes the stop block 807 and the moved movable limit plate 806 to avoid accidental resetting of the movable limit plate 806 in the later stage.

[0061] While the extrusion limit block 704 drives the movable mounting rod 705 to move, the movable mounting rod 705 drives the movable partition 907 to move, so that the movable partition 907 moves out from between the movable guide blocks 906 on both sides thereof, and the mounting spring 905 in a compressed state drives the movable guide blocks 906 on both sides to approach each other until they touch. At the same time, since one movable guide block 906 is connected to the negative pole of the battery through a wire, and the other movable guide block 906 is connected to the positive pole of the fixed electromagnetic block 805 through a wire, and the negative pole of the fixed electromagnetic block 805 is connected to the positive pole of the battery through a wire, when the movable guide block 906 touches, the fixed electromagnetic block 805 is started. When the fixed electromagnetic block 805 is started, the fixed electromagnetic block 805 generates magnetism, so that the fixed electromagnetic block 805 adsorbs the limit needle rod 803, and prevents the limit needle rod 803 from popping out from the movable opening of the fixed cylinder 801.

[0062] When the cable end becomes loose unexpectedly, the cable will move to the outside of the fixed frame head 10, and the friction between the cable and the extrusion limit block 704 will cause the extrusion limit block 704 to be pulled, driving the movable installation rod 705 and the movable connecting rod 903 to move to the inner cavity of the first recess 901, and driving the movable partition plate 907 to move, so that the movable partition plate 907 moves to the inside of the starting slot 904, and the movable partition plate 907 is embedded between the movable guide blocks 906 on both sides, so that the movable guide blocks 906 on both sides are separated, and the power supply of the fixed electromagnetic block 805 is disconnected, so that the fixed electromagnetic block 805 loses its magnetism, and the limiting needle rod 803 is driven to pop out from the inside of the fixed cylinder 801 by the pulling spring 804 in a stretched state, so that the limiting needle rod 803 is in contact with and squeezed with the outside of the cable; in the process of fixing and using the cable, as long as there is abnormal looseness, it will be immediately The limiting needle rod 803 is ejected from the fixing tube 801 at a certain time, and the cable is limited and fixed by the limiting needle rod 803, so as to improve the stability of the cable when it is fixed and used, and the safety of the cable when it is fixed and used, and to avoid excessive pulling force caused by unexpected situations during the cable fixing process, so that the fixed end of the cable is prevented from being detached, affecting the normal process of the later municipal engineering, resulting in the extension of the municipal construction time, thereby affecting the normal travel of citizens in the later period, and even causing a safety accident due to the sudden detachment of the cable; when the cable end needs to be taken out, it is only necessary to open the frame cover 14 in the middle of the top or bottom of the fixing frame head 10, and the limiting needle rod 803 can be manually placed into the fixing tube 801. After the cable end is taken out from the cavity of the fixing frame head 10, the interlocking block 807 and the limiting hook rod 809 are manually separated, and the movable limiting plate 806 is moved to the right to close the movable opening.

[0063] Working principle: When fixing the cable, the present invention presses one end of the cable to pass through the docking circular opening 3 and move it to the inside of the fixed frame head 10, so that the end of the cable passes through the rotating ring 503 and contacts the docking disk 11 and the docking plug rod 12, and pushes the cable end into the center of a plurality of circumferentially distributed docking plug rods 12, so that the plurality of docking plug rods 12 jointly limit the cable end, and increase the friction force when the docking plug rod 12 contacts the cable end. When the docking disk 11 is subjected to the squeezing force, the pressure touch switch 15 is squeezed, and then the pressure touch switch 15 is triggered, and the single-phase motor 501 is started by the pressure touch switch 15 to drive the rotating disk 502, the docking disk 11 and The docking rod 12 rotates, and the end of the cable is twisted through the connecting disc 11 and the docking rod 12, so that a torque is generated on the outside of the cable end; when the single-phase motor 501 drives the rotating disk 502 to rotate, the arc-shaped pushing groove 510 provided on the rotating disk 502 drives the connecting slider 504 to move, and the connecting slider 504 drives the moving slide bar 505 to move toward one side of the cable; when the moving slide bar 505 moves, the reset spring 506 is squeezed, and at the same time, the moving slide bar 505 drives the limit extrusion block 508 to move, so that the limit extrusion block 508 contacts and squeezes the outside of the cable. When the limit extrusion block 508 is squeezed with the outside of the cable, the single-phase motor 501 continues to drive the rotating disk 502 to rotate. The movable plate 502 rotates, so that the arc-shaped pushing groove 510 drives the connecting slider 504 and the moving slide rod 505 to continue to move toward the cable side, ensuring that the limit extrusion block 508 pushes the installation top block 512 to move inside the second recess 513, so that the installation top block 512 is in contact with the pressure controller 514 for extrusion. When the extrusion force reaches the expected value, the alarm will be activated through the pressure controller 514 to tell the staff that the pressure during fixing has reached the expected value. When an unexpected situation occurs and the pressure does not reach the expected value, the alarm will not be activated, so that the staff knows that the fixed position is not firm enough and the fixed end needs to be adjusted later. When the limit extrusion block 508 is in contact with the cable During external contact, the torque on the outside of the cable end further increases the friction and firmness during contact extrusion, and the extrusion fixation at multiple positions can increase the extrusion force on the external end of the cable, thereby improving the firmness of the cable fixation. If one of the extrusion forces is insufficient, the extrusion fixation at other positions can also achieve the fixing effect, and the operation is faster without the need for unnecessary operations, thus avoiding cumbersome and slow operations during fixation. Or if only one fixed end is used for fixation, if an unexpected situation occurs at the fixed end, the fixation will fail and detachment will occur.

[0064] When the end of the cable extends into the fixed frame head 10, the end of the cable passes through the extrusion limit block 704, and the extrusion limit block 704 and the movable installation rod 705 are hinged as the axis to make the inclined extrusion limit block 704 horizontal, and at the same time drive the movable installation rod 705 and the limit lever 701 to rotate around one end of the fixed shaft frame 702; when the extrusion limit block 704 is in a horizontal state, the cable is continued to be pushed, so that friction is generated between the cable and the extrusion limit block 704. When the extrusion limit block 704 is subjected to the friction force, the movable installation rod 705 is driven to move, and the movable installation rod 705 and the left end of the limit lever 701 are driven to move toward the inside of the fixed frame head 10. When the limit lever 701 moves, the compression spring 703 is squeezed. The reaction force of the compression spring 703 increases the extrusion force between the extrusion limit block 704 and the outside of the cable, thereby improving the firmness of the cable when fixed, and increasing the firmness of the cable when fixed by squeezing and fixing the cable end around.

[0065] When the extrusion limit block 704 drives the limit lever 701 to rotate, so that the right end of the limit lever 701 moves toward the side of the mounting ring frame 601, it drives the movable extrusion plate 605 to move toward the side of the mounting ring frame 601. When the movable extrusion plate 605 moves, the conveying airbag 604 is squeezed, and the air inside the conveying airbag 604 is transported to the extrusion airbag 602 through the air hole, so that the extrusion airbag 602 expands and extends out from the inside of the mounting ring frame 601, and then one side of the extrusion airbag 602 is in contact with and squeezed against the outside of the cable, thereby increasing the fit with the outside of the cable, which can not only increase the firmness of the cable fixation, but also improve the stability of the cable when it is fixed.

[0066] When the extrusion limit block 704 moves to a horizontal state, continuing to push the cable will cause the extrusion limit block 704 to be subjected to friction and move to the side away from the movable installation rod 705, and drive the limit elastic rope 802 to move and stretch, and drive the movable limit plate 806 to move through the limit elastic rope 802, so that the movable limit plate 806 is separated from the movable port, so that the movable limit plate 806 loses its restraint force on the limit needle rod 803; and because the extrusion limit block 704 is subjected to friction and moves, it drives the movable installation rod 705 to move, and the movable installation rod 705 drives the movable partition 907 to move, so that the movable partition 907 is separated from the movable guide rods on both sides. When the movable guide block 906 is in contact with the opposite side, the fixed electromagnetic block 805 is activated. When the fixed electromagnetic block 805 is activated, the fixed electromagnetic block 805 is magnetically fixed to the limit needle rod 803. When the movable limit plate 806 moves to the left, the stopper 807 is engaged with the inner part of the limit hook rod 809, and the stopper 807 and the movable limit plate 806 after the movement are fixed to avoid the accidental resetting of the movable limit plate 806 in the later stage. When the cable end is accidentally loosened, The movable mounting rod 705 and the movable connecting rod 903 are driven to move toward the outside of the fixed frame head 10, and the extrusion limit block 704 is pulled, so as to drive the movable mounting rod 705 and the movable connecting rod 903 to move toward the inside of the first notch 901, and drive the movable partition plate 907 to move, so that the movable partition plate 907 moves to the inside of the starting notch 904, and the movable partition plate 907 is inserted between the movable guide blocks 906 on both sides, so that the movable guide blocks 906 on both sides are separated, and the power supply of the fixed electromagnetic block 805 is disconnected, so that the fixed electromagnetic block 805 loses its magnetism, and the limit needle rod 803 is driven to move out of the fixed cylinder 801 through the pulling spring 804 in a stretched state, thereby making the limit needle rod 803 03 Contact and squeeze with the outside of the cable; after the cable end is fixed, as long as the workers find abnormal looseness during use, they will immediately pop out the limit needle rod 803 from the fixing tube 801 to limit and fix the cable, thereby improving the stability of the cable when it is fixed and the safety of the cable when it is fixed, and avoiding excessive pulling force caused by unexpected situations during the cable fixing process, causing the fixed end of the cable to detach, affecting the normal process of the later municipal engineering, resulting in the extension of the time of municipal construction, thereby affecting the normal travel of citizens in the later period, and even causing safety accidents due to the sudden detachment of the cable.

[0067] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
