The utility model discloses a crooked protector of optic fibre, including main part and coupling part, the main part is the semi - cylindrical of two bendings, is provided with the buckle at marginal portion, makes the semicircular cylinder lock of two bendings be in the same place through the buckle, constitutes the drum of a bending, wraps up the lock steadiness that one deck plastic film guaranteed equipment in the department of opening and shutting, is provided with the draw -in groove at two of main part, coupling part be conical, inside cavity, but the facial expression fibre pass, be provided with the buckle with draw -in groove matched with in its stub end and main part junction, processing out a seam in one side of coupling part, through the seam, opening coupling part, coupling part lives the optic fibre parcel. The utility model discloses the advantage: (1 )Ensure that optic fibre bend radius is greater than 3cm all the time, need not to extract operation optic fibre during the loading and unloading of optical link protection ware to do not have to pull to optic fibre and drag. (2 )Make portably, economic benefits is higher, (3 ) simple to operate, easily fixable plays good protection to the optic fibre meander.
