[0034] First, install the mounting plate 1 on the wall with bolts, then twist the bolts to loosen the upper clamping plate 5, remove the upper clamping plate 5 from the lower clamping plate 4, and then pull the three movable seats 3 to move left and right on the tripod 2, and the three movable seats 3 drive the three lower clamping plates 4 to move left and right. When the three lower clamping plates 4 move left and right to a suitable position for cable installation, stop pulling the movable seat 3 to move, and then pull the L-shaped plate 111 to move right, the connecting spring 113 is compressed, and since an anti-slip sleeve is provided on the right side of the L-shaped plate 111, the friction with the hand is increased, which also improves the stability of pulling the L-shaped plate 111, and the L-shaped plate 111 moves to the right, driving the clamping rod 112 to move to the right, and the clamping rod 112 moves to the right and disengages from the holes of the porous plate 11, and then pull the L-shaped plate 111 with The tripod 2 is moved up and down, and the tripod 2 drives the lower clamping plate 4 to move up and down through the movable seat 3. When the lower clamping plate 4 moves up and down to a height suitable for cable installation, stop pulling the L-shaped plate 111 to move up and down, and the tripod 2 stops moving up and down. The L-shaped plate 111 is released. Due to the action of the connecting spring 113, the L-shaped plate 111 moves to the left and resets, driving the clamping rod 112 to move to the left and reset. The clamping rod 112 is reset and inserted into the hole of the porous plate 11. The clamping rod 112 cooperates with the porous plate 11 to lock the tripod 2, and then the cable can be placed on the lower clamping plate 4. The cable is still in contact with the pressing plate 121. When the cable is installed, the upper clamping plate 5 is put back on the lower clamping plate 4, and the upper clamping plate 5 is fixed to the lower clamping plate 4 by bolts. The upper clamping plate 5 and the lower clamping plate 4 clamp the cable The contact wheel 9 contacts the cable, and at the same time, the L-shaped rod 12 is pulled to move upward, the compression spring Ⅰ122 is compressed, the L-shaped rod 12 drives the pressure plate 121 to move upward, and the pressure plate 121 drives the ratchet plate Ⅰ123 to move upward. Under the action of the compression spring Ⅱ125, the ratchet plate Ⅰ123 moves upward and slides on the ratchet plate Ⅱ124, and the pressure plate 121 moves upward and contacts the cable. The pressure plate 121 further presses and fixes the cable to prevent the thinner cable from being difficult to be clamped and fixed by the upper clamping plate 5 and the lower clamping plate 4, so as to adapt to the clamping and fixing of the thinner cable, and then the L-shaped rod 12 is released, and the ratchet plate Ⅰ123 and the ratchet plate Ⅱ124 cooperate to lock the pressure plate 121. At this time, the cable is also installed. During installation, due to the influence of external factors, the cable is prone to vibration or corrosion and loosening. When the cable is loose and moves, the movement of the cable drives the contact wheel 9 to rotate, and the rotation of the contact wheel 9 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the eccentric wheel 10 to rotate. When the eccentric end of the eccentric wheel 10 contacts the tooth plate 6, the eccentric wheel 10 drives the tooth plate 6 to swing downward, and the reset spring I7 is compressed. When the tooth plate 6 swings downward and contacts the cable, the tooth plate 6 cooperates with the lower clamping plate 4 to further clamp and fix the cable to complete self-locking to prevent the cable from loosening and affecting its use, thereby improving the effect of cable installation. Since the teeth of the tooth plates 6 on the front and rear sides are relatively arranged, no matter the cable moves backward or forward, the tooth plate 6 can clamp the cable to complete self-locking.When the cable needs to be replaced or repaired, the upper clamping plate 5 is loosened by twisting the bolt, and the upper clamping plate 5 is removed. The upper clamping plate 5 drives the toothed plate 6 to move and disengage from the cable, and the contact wheel 9 is pushed to rotate through the rotating shaft 8 to drive the eccentric wheel 10 to rotate. The eccentric wheel 10 rotates and resets to stop the toothed plate 6. Due to the action of the reset spring Ⅰ7, the toothed plate 6 swings upward and resets, and then the movable frame 126 is pulled forward to drive the ratchet plate Ⅱ124 to move forward. The ratchet plate Ⅱ124 moves forward and is aligned with the ratchet plate Ⅰ 123 is disengaged, and due to the action of compression spring I 122, the L-shaped rod 12 moves downward and resets, driving the pressure plate 121 to move downward, and the pressure plate 121 drives the ratchet plate I 123 to move downward and reset, and then the movable frame 126 is released. Due to the action of compression spring II 125, the ratchet plate II 124 moves backward and resets to engage with the ratchet plate I 123, and the cable can be removed from the lower clamping plate 4 for replacement or maintenance. When the cable is placed on the lower clamping plate 4 again, the cable can be installed again according to the above operation.

[0035] See also Figure 8 and Fig. 9 As shown, the cable installation bracket also includes a tensioning component installed between the movable seat 3 and the mounting plate 1, the tensioning component includes a fixed frame 13, an electric roller 131, a guide wheel 132, a wind sensor 133, a guide roller 134, a pressing component, a sliding frame 138 and a reset spring II 139, the front and rear sides of the movable seat 3 are fixedly connected with the fixed frame 13, the positions of the front and rear fixed frames 13 close to each other are rotatably connected with the guide wheel 132, the guide wheel 132 can guide the movement of the cable, the side of the front and rear fixed frames 13 away from each other is installed with the electric roller 131, the side of the top of the front and rear fixed frames 13 away from each other is vertically slidably connected with the sliding frame 138, the lower part of the sliding frame 138 and the inner side of the fixed frame 13 are connected with the reset spring II 139, the front and rear two fixed frames 13 are connected with the reset spring II 139, and the front and rear two fixed frames 13 are connected with the reset spring II 139. The upper part of the side sliding frame 138 is rotatably connected with a guide roller 134, and the guide roller 134 is located directly above the electric roller 131. A wind sensor 133 is installed on the top right side of the mounting plate 1, and the wind sensor 133 is electrically connected to the electric roller 131. A pressing assembly is provided on the front and rear fixed frames 13, and when the pressing assembly is in operation, the pressing assembly can press down the cable; the pressing assembly includes a slide bar 135, a pressure roller 136 and a tension spring 137. The left sides of the front and rear fixed frames 13 are vertically slidably connected with the slide bar 135, and the lower right parts of the front and rear slide bars 135 are rotatably connected with the pressure roller 136. When the pressure roller 136 moves downward and contacts the cable, the pressure roller 136 can press down the cable, and a tension spring 137 is connected between the top of the slide bar 135 and the top of the fixed frame 13.

[0036] When the upper clamping plate 5 is removed from the lower clamping plate 4, the cable is first placed on the lower clamping plate 4, and the cable is placed on the guide wheel 132, and then the cable passes between the guide roller 134 and the electric roller 131, and the cable contacts the guide roller 134 and the electric roller 131. Due to the action of the reset spring II 139, the guide roller 134 can be closely in contact with the cable. At this time, the cable is under the pressure roller 136, and the cable can be installed. After the cable is installed, the cable drives the pressure roller 136 to move upward, and the pressure roller 136 drives the slide bar 135 to move upward, and the tension spring 137 is stretched. When the cable is installed, Afterwards, the wind sensor 133 senses the wind force. When the wind force sensed by the wind sensor 133 reaches the set maximum value, the wind sensor 133 controls the electric roller 131 to rotate through the control module. The electric roller 131 rotates and drives the cable to move toward the upper clamping plate 5 and the lower clamping plate 4 through the guide roller 134. The cable in the unclamped part is tightened. At the same time, the cable part between the movable seat 3 and the electric roller 131 is in a loose phenomenon. Under the action of the tension spring 137, the slide bar 135 drives the pressure roller 136 to move downward, and the pressure roller 136 moves downward to tighten the loose cable. In this way, the cable can be in a taut state in a strong wind environment. When the cable is removed, the cable is out of contact with the pressure roller 136. Due to the action of the tension spring 137, the pressure roller 136 moves downward to reset. In this way, the cable can be prevented from shaking continuously in a strong wind environment to affect the stability of the installation, thereby improving the stability of the cable installation.

[0037] See also Fig.10 As shown, the cable installation bracket also includes a baffle 14. The baffle 14 is fixedly connected to the left side of the top of the installation plate 1, and the baffle 14 can block rain and sunlight.

[0038] When the cable is clamped and fixed for installation, the baffle 14 can block rain on rainy days and sunlight on sunny days, and the clamped part of the cable will not come into contact with rain and sunlight. In this way, the clamped part of the cable can be prevented from being corroded and hardened by rain and sunlight, causing loosening, thereby ensuring the safety of the clamped part of the cable.

[0039] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
