The utility model relates to a needle selector, in particular to an eight-section wear-resistant needle selector. The eight-section wear-resistant needle selector comprises a support, coils, a circuit board, a needle selecting blade, a left side plate and a right side plate. The circuit board is installed at the bottom of the support. The circuit board is externally connected with a power source. The coils are installed on the left side plate and the right side plate and are connected with the circuit board through leads. The left side plate and the right side plate are fixed to the two sides of the support. The needle selecting blade is fixed and located to the end of the support through a hinge pin and an end cap. The two sides of the needle selecting blade are inwards recessed. The angle of a too bit of the needle selecting blade ranges from 120 degrees to 140 degrees. According to the design scheme, the angle of the tool bit of the needle selecting blade is changed, so that the stress of the work surface of the blade is reduced, as a result, wear of the blade is relieved, and therefore the eight-section needle selector is resistant to wear.
