[0002] Power engineering is indispensable in people's lives, and an indispensable step in power engineering is cable laying. Traditional cable layers cannot control the retracted and released positions of cables during use, and it is easy for cables to be intertwined during cable laying, causing cable entanglement and affecting cable laying efficiency.

[0003] Patent number CN216548926U is an anti-entanglement wire release for power construction. A threaded rod is rotatably arranged at the top of two mounting holes, and an anti-entanglement frame is sleeved on the threaded rod. The rollers at both ends of the winding frame are connected to the threaded rod through gears and toothed belts. The winding frame drives the threaded rod to rotate during the wire release process, so that the anti-entanglement frame moves along the threaded rod, and the wire release position is controlled by the wire release groove on the anti-entanglement frame, which avoids the entanglement of the cable during the laying process and improves the wire release efficiency of the wire release.

[0004] Although the problem of cable entanglement during the cable laying process has been solved, the lack of an angle adjustment device may make it difficult to adjust the angle of the cable release during the cable laying process, making it inconvenient to carry out the cable laying work. When the angle needs to be adjusted, the device may need to be rotated as a whole, which brings inconvenience to people. Therefore, it is necessary to design an angle-adjustable power construction cable release. Utility Model Content
