1. Because the long diameter of the screw is relatively small, the screw is easy to turn over when passing through the fork of the clamping valve of the nozzle, so the swing nozzle is adopted;

2. The tightening direction requires horizontal tightening, and the Hold screw cylinder is added to prevent the screw from being inclined and falling under the action of gravity. Usually tighten horizontally and from bottom to top, requiring Hold  screw function;
