[0026] As a technical optimization solution of the utility model, by setting a limit groove 8, a movable column 9 and a limit block 10, the screw 63 is rotated to make the thread push the movable column 9 to move upward, and the movable column 9 is limited by the limit groove 8 and the limit block 10 to prevent the movable column 9 from rotating with the screw 63.

[0027] refer to Figure 2 The fixing assembly 7 includes a fixing tooth 71, which is fixedly connected to the top of the clamp 3. The top of the supporting hardware 1 is movably connected with a cover plate 72. A plurality of cover plates 72 are provided, and the plurality of cover plates 72 are distributed in a circular shape with equal distances.

[0028] As a technical optimization solution of the utility model, by setting a fixed tooth 1 71 and a cover plate 72, the cover plate 72 is driven to move when the movable column 9 moves, and then the cover plate 72 drives the fixed tooth 2 11 to separate from the fixed tooth 1 71, so that the length of the clamp 3 can be adjusted during use, and other cover plates 72 can be adjusted by rotating the knob 64 at different positions.

[0029] refer to Figure 3 The bottom of the cover plate 72 is fixedly connected with the fixed tooth 2 11 , the bottom of the fixed tooth 2 11 is meshed with the top of the fixed tooth 1 71 , and the bottom of the cover plate 72 is fixedly connected with the top of the moving column 9 .

[0034] As a technical optimization solution of the utility model, by setting a limit block 2 13, after the cover plate 72 drives the fixed tooth 2 11 to move upward, the card tray 4 is moved upward, and then the card tray 4 drives the card part 3 to move upward, so that the limit block 2 13 is separated from the limit groove 2 12, and then the new card part 3 is placed in the connecting groove 2, and then the cover plate 72 is downward to fix the card part 3, so that the card tray 4 can be quickly replaced when it is damaged.

[0035] The working principle and use process of the utility model are as follows: when in use, the card member 3 is placed in the connecting groove 2, and the card member 3 is limited, which can make the installation of the card member 3 more convenient. Then, the wire is placed in the card holder 4 and the connecting strand 5 is rotated to fix the wire. The bearing 62 is fixed through the movable groove 61. Then the bearing 62 can support and limit the screw 63. The knob 64 is rotated to drive the screw 63 to rotate. The screw 63 is rotated to make the thread push the moving column 9 to move upward. The moving column 9 is limited by the limiting groove 18 and the limiting block 10 to prevent the moving column 9 from rotating with the screw 63. When the moving column 9 moves, the cover plate 72 is driven to move, and then the cover plate 72 drives the fixed tooth 2 11 to separate from the fixed tooth 1 71. The length of the card member 3 can be adjusted when in use. By rotating different positions The knob 64 can be used to adjust other cover plates 72. After adjusting the position of the card 3, the knob 64 is rotated in the opposite direction to drive the screw 63 to rotate in the opposite direction through the knob 64, so that the thread pushes the movable column 9 to move downward, and then the movable column 9 drives the cover plate 72 to move downward, so that the fixed tooth 2 11 engages with the fixed tooth 1 71 to fix the card 3. When moving the card 3, the limit groove 2 12 and the limit block 2 13 are used to limit the card 3 to prevent the card 3 from being separated from the connecting groove 2. After the cover plate 72 drives the fixed tooth 2 11 to move upward, the card receiving tray 4 is moved upward, and then the card receiving tray 4 drives the card 3 to move upward, so that the limit block 2 13 is separated from the limit groove 2 12, and then the new card 3 is placed in the connecting groove 2, and then the cover plate 72 is downward to fix the card 3. The card receiving tray 4 can be quickly replaced when it is damaged.

[0036] To sum up: the power line protection hardware, by setting the connection groove 2, can put the clamp 3 into the connection groove 2, limit the clamp 3, can be more convenient when installing the clamp 3, and then put the wire into the clamping tray 4 and fix the wire by rotating the connecting strand 5, which solves the problem that the existing protection hardware cannot adjust the length of the stabilizing block when in use, and the stabilizing block cannot be replaced separately when replaced or installed, resulting in other stabilizing blocks being easily separated from the protection hardware during replacement, which is very inconvenient when in use.
