The locking mechanism 43 includes a locking rod 431, a pull plate 432 and a reset spring 433, and the end of the locking rod 431 is fixedly connected to the pull plate 432, and The inner side of the pull plate 432 is fixedly connected to a return spring 433, the end of the return spring 433 is fixedly connected to the inner side of the pull plate 432, and the other end of the return spring 433 is fixedly connected to the outer side of the load-bearing block 41, and the pull plate 432 forms an elastic structure with the load-bearing block 41 through the return spring 433. By setting the pull plate 432 and the load-bearing block 41 in an elastic structure, when the staff releases the pull plate 432, the rebound force of the return spring 433 can drive the locking rod 431 to pass through the load-bearing block 41 and insert into the limiting groove 446, and the outer surface of the locking rod 431 is movably connected to the inside of the load-bearing block 41, and the inner surface of the other side of the load-bearing block 41 is rotatably connected to the limiting mechanism 44. The limiting mechanism 44 includes an arc-shaped limiting plate 441, a connecting sleeve 442, a connecting shaft 443, a second insulating protective pad 444, a locking block 445 and a limiting groove 446, and the end of the arc-shaped limiting plate 441 is fixedly connected to the connecting sleeve 442, and the inner surface of the connecting sleeve 442 is fixedly installed with a connecting shaft 443, the outer surface of the connecting shaft 443 is fixedly connected to the inside of the connecting sleeve 442, and the end of the connecting shaft 443 is rotatably connected to the inside of the bearing block 41, and the connecting sleeve 442 forms a rotating structure with the bearing block 41 through the connecting shaft 443. By configuring the connecting sleeve 442 and the bearing block 41 into a rotating structure, the limiting mechanism 44 is convenient for the staff to perform quick switching processing, and The inner side of the arc-shaped limiting plate 441 is fixedly connected to a second insulating protective pad 444, and the other end of the arc-shaped limiting plate 441 is fixedly installed with a locking block 445.

By setting the locking rod 431 and the locking block 445 as a snap-fit structure, the locking rod 431 can be easily inserted into the interior of the locking block 445 to complete the locking work. The cable terminal body 5 is movably installed on the inner surface of the mounting assembly 4, and the outer surface of the fixed plate 1 is movably installed with an adjustable bearing assembly 6.

Then the staff fits the cable terminal body 5 into the inner surface of the bearing block 41, and then grasps the arc-shaped limiting plate 441 and drives the rotation of the connecting shaft 443 in the bearing block 41 through the connecting sleeve 442 to drive the inner surface of the arc-shaped limiting plate 441 to move toward the outer surface of the cable terminal body 5.

The pull plate 432 drives the locking rod 431 through the supporting block 41 and into the interior of the limiting groove 446 through the rebound force of the reset spring 433, so as to complete the locking work of the limiting mechanism 44.

After the cable terminal body 5 is installed, its end is connected to the connector in the energy storage power station. At this time, the staff can assist the staff in connecting the cable terminal body 5 by adjusting the angle of the adjustable supporting component 6.
