After assembly, the first axis L1, the second axis L2, and the third axis L2 are arranged coaxially .

After the hand tool 60 has been applied to a predetermined torque value, the hand tool 60 is rotated by a predetermined angle according to the requirements of the specification. At this time, the angle gauge 20 is assembled to the hand tool 60, see Figures 5 to As shown in 7, firstly loosen the tightening member 522, so that the positioning rod 523 can rotate and move freely, so that the positioning rod 523 can be fixed to a reference position B, and then tighten the tightening member 522 to fix the positioning rod 523 keeps against the fixing part; then, referring to FIG. 7, turn the angle portion 31 of the display member 30 again, because the pivoting portion 32 is pivoted on the socket portion 41 of the connecting member 40, Therefore, the display member 30 can be relatively rotated, and the angle mark 311 of the angle portion 31 is rotated to the position of the arrow 531 of the indicating portion 53, such as 0 degrees or 90 degrees. When the position of the angle portion 31 is properly rotated Then, referring to FIG. 8, the shaft 62 of the hand tool 60 rotates, so that the head 61 of the hand tool 60 rotates. When rotating, the embedding portion 42 of the connecting member 40 is locked Set in the fitting portion 611, the connecting member 40 will rotate synchronously, and the socket 41 on the top of the connecting member 40 will also drive the pivoting portion 32 to rotate together, so that the angle portion 31 will also rotate However, because the positioning portion 52 of the positioning member 50 is locked against the reference position B, the positioning member 50 cannot rotate. At this time, the assembly hole 511 of the assembly portion 51 will be relative to the connecting member The outer side of the circumferential portion 43 of 40 rotates, thereby causing a relative angular displacement between the angle portion 31 and the indicating portion 51. In this way, it can be known that the head 61 of the hand tool 60 rotates relative to the fixed indicating portion 51 How many angles.

If multiple rotation angles are required, please refer to Figure 9. Because the display member 30 can be rotated relative to the connecting member 40, so long as the display member 30 is rotated, the pivoting portion 32 is relative to the socket portion 41. By rotating, the relative position between the angle portion 31 and the indicating portion 53 can be adjusted, so that the indicating portion 53 can be re-indicated at the reference point position, and then the angle measurement can be repeated.

In addition, it is worth mentioning that, referring to Fig. 10, when ordinary people apply force to operate the hand tool 60, they will get used to holding the shaft 62 with one hand and the head 61 with the other hand; the display member 30 can also be used as It is used for holding by the user's hand, because the pivoting portion 32 is pivoted in the socket portion 41 of the connecting member 40, so when the hand is held on the display member 30, the hand tool 60 Its rotation will not be disturbed.
