A fabric clip having an easily detachable spring. The fabric clip comprises a bottom plate, wherein an L-shaped clamping frame is disposed on the bottom plate; the L-shaped clamping frame and the bottom plate form an opening portion and a tail portion connected to the end of the opening portion; a cutter clip body is arranged at the opening portion; a push rod is arranged on the top of the cutter clip body; the push rod and the L-shaped clamping frame are connected by means of a pin; a hanging rib is arranged on the L-shaped clamping frame; the hanging rib is located between the pin and the tail portion; the hanging rib and the push rod are connected by means of a spring; and two ends of the spring are movably connected to the hanging rib and the push rod respectively. In the present technical solution, the spring is easy to disassemble, and the fabric clip does not need to be disassembled as a whole, thereby significantly saving maintenance time; in addition, when the spring is in operation, the diameter and pitch of the spring are changed, and a variety of deformations are superimposed to achieve a spring force action, such that the spring has a variety of deformations when in operation, with each degree of deformation being small.
