Abstract

The utility model discloses a bolt fastening detacher which comprises a first rope, a seat A, a jack and a seat B. The jack is arranged between the seat A and the seat B. Two holes A are formed in the seat A. The first rope is connected with a first wrench after sequentially penetrating through the two holes A. The seat A, the jack and the seat B are arranged at proper positions, the first rope with the proper length is selected, and the output end of the jack pushes the seat A and pulls the first rope so that the first wrench can be screwed within a certain angle. As the rope occupies small space, the detacher is particularly suitable for operation of fastening or disassembling large bolts and nuts which can not be disassembled by special equipment due to narrow operation space.
