[0043] In the specific use of this embodiment, when it is necessary to connect the electrical components inside the meter body 2, the motor 79 is first started through the external PLC, and the output shaft of the motor 79 rotates to drive the rotating shaft 710 coaxially connected thereto to rotate, and the rotating shaft 710 rotates to drive the same-side gear 78 coaxially fixed thereto to rotate, and the rotation of the gear 78 drives another gear 78 meshing therewith to rotate, and the rotation of the other gear 78 drives the rotating rod 77 coaxially fixed thereto to rotate, and the rotation of the rotating rod 77 drives the same-side rotating column 72 coaxially fixed thereto to rotate, and the rotation of the rotating column 72 drives the screw 73 coaxially fixed thereto to rotate, and the rotation of the screw 73 drives the moving rod 74 threadedly connected thereto to move, and the moving rod 74 moves under the guidance of the guide block 76 and the guide groove on the top surface of the mounting plate 1, and the movement of the moving rod 74 drives the box cover 4 fixed thereto through a plurality of connecting rods 75 to move in a direction away from the meter body 2, and when the box cover 4 moves to a suitable position, the motor 79 is turned off through the external PLC;

[0044] When the electric meter body 2 is subjected to an external impact, the external impact force acts on the outer wall of the electric meter body 2, and the electric meter body 2 transfers the impact force to a plurality of gaskets 62, and the plurality of gaskets 62 transfer the impact force to a plurality of telescopic rods 64. The telescopic rods 64 move toward the direction of the mounting plate 1 under the action of the impact force, and the telescopic rods 64 indirectly drive the springs 63 on the same side to be compressed during the movement.
