[0026] Further Figure 2 As shown, it is worth explaining in detail that a mounting frame 9 is fixed to a side wall of one side of the shell 2, and the operating shaft 75 is rotatably connected to the side wall of one side of the mounting frame 9. The vertical cross-section of the mounting frame 9 is concave in shape. Through the setting of the mounting frame 9, the operating shaft 75 can be operated in a relatively stable state, ensuring that the operating shaft 75 is relatively stable under long-term use.

[0027] The present invention has the following working process: when the busbar bridge body 1 is to be installed, the load-bearing plate 3 is first aligned with the positioning groove 10, and the load-bearing plate 3 is pressed, and the extrusion transmission effect between the load-bearing plate 3 and the extrusion plate 73 is utilized to make the connecting rod 72 move after being stressed, and the elastic effect of the spring 74 is utilized to make the extrusion plate 73 automatically rebound and reset when the position of the extrusion plate 73 coincides with the limiting groove 78, so that the extrusion plate 73 is engaged with the limiting groove 78, and the installation of the loading plate is completed, and the screw rod 5 is inserted into the installation hole groove 4 , screw the nut 6 to position the screw rod 5, thereby completing the overall installation of the busbar bridge body 1.

Through the setting of the limiting plate 11, a certain limiting effect is provided for the bearing plate 3 when it is installed, thereby ensuring that the bearing plate 3 is in a relatively stable state after installation, and avoiding the bearing plate 3 from shaking or even shifting.

[0031] Further as Figure 3 As shown, it is worth explaining in detail that two symmetrically distributed guide blocks 12 are fixed to the side wall of one side of the connecting plate 71, and a plurality of symmetrically distributed guide grooves 13 are opened on the side wall of one side of the shell 2.
