The invention discloses an easily-twisted flexible bolt with a straight-line-shaped thread end head. The bolt comprises a bolt head, a screw rod connected with the bolt head and a nut connected with the screw rod; the screw rod is a steel strip made of a spring steel material, the end of the screw rod is arranged to the thread end, the thread end head connected with the thread end in a matched manner is arranged at the thread end, a straight line shape is formed in the thread end head, and two handles which are upwards bent and are in a circular arc shape are symmetrically arranged on the two sides of the nut; the bolt is provided with the screw rod made of a spring steel material, component connection with through holes not formed in the same straight line is achieved, the straight-line-shaped thread end head is arranged, the defect that when a traditional bolt is fastened, one end is fixed, and the other end is tightly twisted is overcome, the circular-arc handles are arranged on the nut, the stress area is increased, torque acting on the nut is increased, component fastening can be conveniently and flexibly achieved at one end of the bolt, time and labor are saved, the labor intensity is reduced, production efficiency and work efficiency are improved, and the bolt is suitable for multiple occasions and is worth of wide popularization.
