DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a torsion adjuster, and more particularly, to a torsion adjuster for preventing an unreasonable misalignment due to reciprocal movement of the adjuster when the torsion is too large.

[0002]

2. Description of the Related Art It is known that a commercially available torsion adjuster for a pneumatic or electric tool is still operating smoothly because the force applied to the torsion adjuster is large at the beginning of the plug nut (or bolt). And there is no problem of moving back and forth. However, as the bolt or screw is inserted, the torsion adjuster operates by pneumatic or power transmission. In the conventional torsion adjusters, all the springs are pushed out by two facing meshing dentitions, and the transmission stress is transmitted to the front end of the torsion adjuster. Therefore, the meshing of the two discs pushes out the spring when receiving the transmission of the tool. In this way, a phenomenon in which the torsional adjuster moves back and forth occurs, and the plugging stress of the direct pneumatic or power tool and the accuracy of the operation are reduced.

When the torsion force gradually increases in accordance with the degree of insertion of the bolt, the fore-and-aft movement occurs in accordance with the interlocking pelvis of the threading, and the threading is performed in the threaded groove of the bolt or nut. No tight coupling between them. This has caused the threading and the bolt to separate from the threading groove, causing friction between the threading groove and the threading, and causing damage and damage to the threading.

For this reason, the present inventor has accumulated many years of designing and experience of related tools, and has made research and improvement on the above-mentioned drawbacks of the conventional torsion adjuster. It is.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a torsion adjuster which, even if an electric or pneumatic tool is subjected to a relatively large stress, does not yet cause a back-and-forth movement and can achieve the best torsion adjustment and force.
