The second sleeve portion is formed outside the perforation of the outer tube 2, and the second sleeve portion is grooved for the wrench to fit; the plurality of balls 7 are received in the first nip portion of the first block 3 And the second engaging portion of the second connecting block 4, that is, the ball 7 is received between each of the first engaging portion and the second engaging portion, and the second connecting block 4 is driven. The plurality of balls 7 and the first block 3 are rotated together; one end of the elastic member abuts against the bottom of the outer tube 2, and the other end abuts against the second block 4.

The patented torque joint structure principle is:

By rotating the outer cylinder 2, that is, adjusting the relative position between the inner cylinder 1 and the outer cylinder 2, adjusting the degree of compression of the elastic member to set the rotational torque of the torque joint, driving the second joint 4, so that The second connecting block 4 rotates the plurality of balls 7 and the first connecting block 3 to rotate, and the first fitting portion is sleeved to rotate the screwing member, and when the screwing member is locked to a certain extent, the first connecting portion A block 3 is subjected to resistance, and the axial force of the first block 3 and the second block 4 is greater than the elastic force of the elastic member, and the second block 4 is displaced toward the elastic member, so that the elastic member is subjected to the elastic member. Compressed, the second block 4, the second block 3 and the plurality of balls 7 are separated from each other, and the second block 4 can no longer drive the first block 3, which is the principle of the torque joint.

However, the missing structure of this conventional torsion joint structure is:

In addition, as shown in the third figure of the bulletin, a plurality of spheres 7 are annularly arranged in a ring shape, and the plurality of spheres 7 are received in the first occlusion portion and the second junction 4 of the first junction block 3. Between the second occlusal portions, that is, each of the spherical bodies 7 is accommodated between each of the first occlusal portion and the second occlusal portion. When the torque joint structure is assembled, each spherical body 7 is assembled. The spherical body 7 is formed in a bead shape between each of the first occlusal portion and the second occlusal portion, and the spherical body 7 is naturally rolled at the second occlusal portion, and the spherical body 7 is It is easy to fall at the second occlusal portion and the ball 7 is difficult to pick up, so that the assembly of the ball 7 is relatively inconvenient, time consuming and labor intensive, and the production time cost is increased.

In view of the lack of the torsion joint structure of the above-mentioned conventional patent case, the inventors have been engaged in the manufacturing experience of related industries for many years, and finally have a product that can solve the drawbacks of the torque joint structure.
