[0158] 6,The buckle structure (the buckle structure includes the clamping tongue 22 and the folded edge 21 which are distributed and parallel to each other, and the crossbeam clamping groove is formed between the clamping tongue 22 and the folded edge 21) on the mounting bracket can be attached to the crossbeam 1001 installed on the original junction seat 1000 of the switch machine (the crossbeam is clamped in the crossbeam clamping groove), when the mounting screw (i.e. the second screw) is loose or even fails, the switch machine gap image acquisition device will not fall off, and the normal use of the switch machine is not affected.

[0159] It should be noted that the original gap image acquisition device of the prior art switch machine is installed at the wiring terminal group mounting hole below the tension spring on the switch machine junction seat (i.e. the mounting hole is shared with the wiring terminal group), if the acquisition device fails, the switch machine wiring terminal group needs to be removed first before the gap image acquisition device can be replaced, which is inconvenient to install and disassemble and has low work efficiency.

[0160] The above is only the preferred embodiment of the present application, and it should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the scope of protection of the present application.
