[0032] The working principle of the torque wrench with replaceable wrench heads provided by this utility model is as follows: In use, the first wrench head 2, the second wrench head 21, and the remaining second wrench heads 21 all have different diameters. When it is necessary to disassemble or assemble a fastener, the first wrench head 2 is locked onto the outside of the fastener. The handle 11 is gripped and rotated. The handle 11, through a locking mechanism, drives the first wrench head 2 to rotate, thereby completing the disassembly or assembly of the fastener. When it is necessary to disassemble or assemble fasteners of different diameters, the T-shaped push block 37 is moved to the left. The T-shaped push block 37 drives the cuboid locking block 35 to move to the left and compresses the support spring 36. When the cuboid locking block 35 moves to the left, it disengages from the first magnetic block 3. The magnetic connection and disconnection of the first wrench head 2 from the first cuboid groove 31 are achieved by rotating the first wrench head 2. Then, the appropriate second wrench head 21 is pulled out. When the second wrench head 21 is pulled out, the second magnetic block 43 is released from the magnetic connection with the cuboid iron block 44, thus completing the removal of the appropriate diameter second wrench head 21. Similarly, the working principle of storing the first wrench head 2 in the placement hole 4 is the same. At this time, the locking mechanism locks the second wrench head 21 in the same way, so that the replaced wrench head can be properly placed, and the wrench head is not easy to be lost. This not only reduces the tool management cost, but also prevents the lack of a suitable wrench head from affecting work efficiency.
