Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Please refer to Figure 1-Figure 3 In the embodiments of the utility model, a high-low bus bridge shell body comprises a frame 1, a mounting seat 2 is fixedly installed on the inner side of the frame 1, a cable 3 is arranged on the inner side of the mounting seat 2, and the shell body is characterized in that a limiting mechanism 4 is arranged on the mounting seat 2.

[0030] The limiting mechanism 4 comprises a transmission unit and a supporting unit.

[0031] The supporting unit is used for providing pre-connection for the installation of the cable 3.

[0032] The transmission unit is used for limiting and clamping the cable 3.

[0033] The supporting unit comprises an upper cover 401 and a positioning groove 402.

[0034] The upper cover 401 is installed on the top end of the mounting seat 2 through bolts, and the upper cover 401 is used for providing extrusion thrust for the vertical movement of the movable rod 403.

[0035] The positioning groove 402 is arranged on the outer wall of the mounting seat 2, and the positioning groove 402 is used for providing support for the placement of the cable 3.

[0036] The transmission unit comprises a movable rod 403, a force rod 404, a transmission rod 405, a clamping block 406 and a spring 407.

[0037] The movable rod 403 is vertically and slidably installed on the inner wall of the mounting seat 2 and extends to the top end outer wall of the mounting seat 2, and the movable rod 403 is used for giving the force rod 404 axial movement extrusion thrust.

[0038] The force rod 404 is axially and slidably installed in the mounting seat 2, and the force rod 404 is used for synchronously driving the transmission rod 405 to move axially.

[0039] The transmission rod 405 is axially and slidably installed on the inner wall of the mounting seat 2 and extends into the positioning groove 402, and the transmission rod 405 is used for synchronously driving the clamping block 406 to move.

[0040] The clamping block 406 is fixed to the end of the transmission rod 405, and the clamping block 406 is used to clamp the mounting seat 2 located inside the positioning groove 402;
