[0023] When it is necessary to install the internal components of the energy storage converter, the handle 7 is gripped and pulled outward, and the handle 7 will drive the pull rod 8 to move outward, and the pull rod 8 will drive the two movable rods 16 to move, so that one end of the two movable rods 16 moves from the inside of the column 5 to the inside of the clamping ring 6, thereby releasing the fixed connection between the column 5 and the clamping ring 6, so that the clamping ring 6 can move downward along the outside of the column 5, and the clamping ring 6 will drive the fixing plate 2 to move downward, thereby facilitating the adjustment of the height of the fixing plate 2;

[0024] Furthermore, two limiting rods 15 are fixedly connected to the inner side of the pull rod 8. One end of the limiting rod 15 is plug-connected to the inside of the fixed plate 2. When the handle 7 drives the pull rod 8 to move outward, the pull rod 8 will drive the limiting rod 15 to move outward along the inside of the fixed plate 2.

[0025] Furthermore, the bottoms of the two clamping plates 10 are fixedly connected to two threaded seats 11, a slide groove 14 is processed in the middle of the fixed plate 2, and the threaded seat 11 is movably connected to the inside of the slide groove 14. A motor 12 is provided at one end of the bottom of the fixed plate 2, and one end of the motor 12 is fixedly connected to a bidirectional threaded rod 13, and the two threaded seats 11 are respectively threadedly connected to the two ends of the bidirectional threaded rod 13;

[0026] When the internal components of the energy storage converter need to be installed, the components are placed between the two clamping plates 10, and then the motor 12 is started. The motor 12 will drive the bidirectional threaded rod 13 to rotate, and the bidirectional threaded rod 13 will drive the two threaded seats 11 to move. The two threaded seats 11 will drive the two clamping plates 10 to move closer to each other, thereby facilitating the clamping and fixing of the internal components of the energy storage converter.

The bottom of the clamping block 21 is slidably connected to the inside of the clamping groove 22. When the threaded seat 11 drives the splint 10 to move, the splint 10 will drive the two clamping blocks 21 to move, and the clamping blocks 21 will move along the inside of the clamping groove 22. By providing the clamping groove 22, the splint 10 can maintain a stable state when it moves.

[0031] Working principle: By pulling the handle 7, the pull rod 8 is driven to move outward, and the pull rod 8 will drive the two movable rods 16 to move outward, so that the movable rod 16 drives the limit ring 18 to move outward, and the limit ring 18 moves from the inside of the movable groove 19 to the inside of the limit groove 20, thereby releasing the fixed connection between the column 5 and the snap ring 6, so that the snap ring 6 can move downward along the outside of the column 5, and the snap ring 6 drives the fixed plate 2 to move downward, thereby facilitating the adjustment of the height of the fixed plate 2.
