The locking rod of the position control element penetrates the locking block and the slot hole of the main body, and then a gasket and positioning are sequentially placed on the other end of the main slot hole. The nut is locked on the thread of the rod end, so that the convex arc surface of the wedge of the position control element can fit into the arc groove of the stopper. Then turn the position control upwards through the pull rod of the position control element (left or right direction can be used), causing the convex arc surface and the arc groove to disengage from the fit and form a pushing effect (the sides of the arc groove are all chamfered, so there is no It will form resistance when the convex arc surface rotates), and then make the opening of the main body produce a tightened displacement distance, so that the fastening and tightening or loosening can be quickly completed with a rotation angle of no more than 90 degrees.

The quick-release harness described above can change the pull bar of the position control element into a hexagonal slot, not only the hexagonal wrench can be used instead of the rotation to apply force, but also because there is no obstruction that affects the displacement at all, there is no limit to the promotion of use. Effect.

The said quick-release bundle sleeve can change the cooperation between the convex arc surface of the position control element and the stop block and the arc groove into a fit with several corner blocks and corner grooves relatively distributed on the end surface, and the corner blocks can be embedded or Withdrawing from the corner groove, the stop block and the position control element are moved closer or apart, so as to achieve another effect of tightening, fastening and loosening.
