[0005] As a preferred technical scheme, a slot is arranged on the insertion box body on both sides of the adapter clamping groove.

[0006] As a preferred technical scheme, a reinforcing rib is arranged on the inner side wall of the insertion box body.

[0007] As a preferred technical scheme, the buffer spring is a tower spring and two buffer springs are arranged.

[0008] Due to the adoption of the above technical scheme, the utility model has at least the following beneficial effects: by changing the existing insertion sheet type optical branching filter structure, using a half-slot branching filter clamping groove to fix the device, and increasing a buffer spring in the branching filter clamping groove to buffer and reduce internal stress, the internal device of the insertion sheet branching filter has a buffer force when falling, which does not cause internal fiber breakage and coupling surface shedding of the device, greatly reduces the risk of use, and improves the product stability and market competitiveness.
