The invention discloses textile thread clippers facilitating replacement of cutting heads. The textile thread clippers comprise a first handle, a second handle is movably arranged on one side of the first handle, one end of the first handle and one end of the second handle are movably hinged together through a fixing screw rod, moreover, the middle portion of the first handle and the middle portion of the second handle are connected with a spring, the first cutting head is arranged on the outer surface of the upper end of the first handle, and a second cutting head is movably arranged on the outer surface of the upper end of the second handle. According to the textile thread clippers, the spring is arranged so that when the cutting heads are excessively stressed for closing cutting, the first handle and the second handle of the textile thread clippers can be restored under the tension of the spring by pressing the spring well and initiatively, then the cutting heads of the textile thread clippers can be separated, connecting blocks and rotating bolts are arranged so that the rotating bolts can be manually rotated to enable the rotating bolts to be loosened, after looseness, one connecting block of the textile thread clippers can be pulled out from the first handle, and then replacement can be carried out very conveniently after the thread clipper cutting heads of the textile thread clippers are damaged.
