[0025] The insertion block 202 is symmetrically arranged on the connecting rod 1.

[0026] The limiting block 102 is provided with a plurality of inclined surfaces away from one end of the tension spring 103.

[0027] The fence frame 3 is provided with a first fixed block 301 and a second fixed block 302, the insertion rod 2 and the connecting rod 1 are respectively provided with a second connecting frame 201 and a first connecting frame 101, the second fixed block 302 is rotationally connected with the second connecting frame 201, the first connecting frame 101 is provided with a bolt 303, the bolt 303 is connected with the first connecting frame 101 through a contraction spring 304, and the first connecting frame 101 and the first fixed block 301 are both provided with a insertion hole matched with the bolt 303.

[0028] In rail transit, when current limiting needs to be performed, a plurality of fence frames 3 are assembled, when the fence frames 3 are assembled, the plug block 202 on one of the fence frames 3 is inserted into the T-shaped groove 4 on the adjacent fence frame 3, when the plug block 202 contacts the inclined surface of the limiting block 102, the plug block 202 continues to move and pushes the limiting block 102 back to move into the sliding groove 5, when the insertion slot on the plug block 202 corresponds to the limiting block 102, under the action of the tension spring 103, the limiting block 102 enters the insertion slot to limit and fix the plug block 202, thereby realizing the assembly of the fence frame 3 and effectively improving the assembly efficiency of the fence frame 3.

[0029] The T-shaped groove 4 can realize the installation of the corner, and thus the safety current limiting fence can be freely adjusted to meet the needs of different paths.
