Description

Technical Field

[0002] Wires and cables are wire products used to transmit electrical energy, information, and achieve electromagnetic energy conversion. Currently, when installing existing wires and cables, they must be manually laid on a power tower and then secured. Existing tightening devices, such as those disclosed in patent document CN110932182A, utilize a first clamp and a second clamp to securely mount the device to the power tower, facilitating the securing of the entire device. A handle and a rotating shaft are used to rotate a threaded screw, adjusting the position of the movable block on the threaded screw and the positions of the first and second clamps to facilitate tightening the wire and cable installation. The first clamp clamps the wire and cable into a clamping groove.

[0003] However, the device has the following shortcomings: when fixing, the wires and cables cannot be effectively fixed and clamped. Therefore, when the wires and cables need to be tightened, the wires and cables slide due to the poor clamping effect, and the tightening of the wires and cables cannot be achieved; in addition, there is a problem of insufficient fixing stability, which will cause the device to shake when in use, which is not conducive to the tightening of the wires and cables; furthermore, when the device is tightened for the installation of wires and cables, a manual tightening method is adopted, which makes actual use inconvenient and cannot meet the needs of construction workers.
