[0002] Cable terminations are devices installed at the beginning and end of power cable lines to connect with other electrical equipment. As a weak point in the operation of 10kV power cables, cable terminations often need to be twisted during line installation and maintenance to avoid excessive mechanical stress between the lugs and bolts, facilitating easier installation and removal, and preventing overheating caused by poor contact between the lugs and bolts. However, currently, cable terminations are generally twisted manually, which is time-consuming, labor-intensive, and inconvenient for operators. Furthermore, the confined space of underground work also poses significant safety hazards to workers. Summary of the Invention

[0007] As a preferred option, the number of bearings is multiple.

[0008] As a preferred embodiment, there are multiple rotating shafts, each corresponding to a bearing. The multiple rotating shafts include a first rotating shaft connected to the middle of the rotating block, and one end of the connecting rod is rotatably sleeved on the first rotating shaft.

[0013] As a preferred embodiment, the strut assembly also includes a movable block, which is fixedly connected to the head end of the adjusting rod and slidably sleeved on the fixed rod.

[0014] In summary, the present invention has the following advantages: the present invention effectively supports the two arms of the distribution cabinet by means of support rod blocks, drives the pull rod to turn the cable by means of slider, and realizes this action by means of the rotation of lead screw.
