[0015] 2. The utility model discloses that the positioning bolt is reversely rotated, the main ruler can slide in the notch, the position of the fixed measuring claw is adjusted, the fixed measuring claw corresponds to the mark of one steel bar, the position of the movable measuring claw is adjusted through the sliding vernier, the movable measuring claw corresponds to the mark of the other steel bar, after the position of the fixed measuring claw and the movable measuring claw is fixed, the connecting quality of the steel bar sleeve can be checked quickly through the tool when the subsequent inspection is carried out, the inspection time is saved, and the working efficiency is improved.

[0016] 3. The utility model discloses that the retaining ring is rotated one by one, the distance between the two retaining rings can be adjusted according to the length of the steel bar sleeve, so that the connecting quality of the steel bar sleeve of different specifications can be checked quickly.
