The position of the mechanical bolt in operation should be in line with the axis of the batch shaft and the screw perpendicular to the surface of the locking screw, the lock is vertical under the screw, it cannot tilt or swing. Otherwise, the screw won't lock, slide, blow out and tighten. To this end, we have compiled related issues and solutions. The slip phenomenon occurs, i.e. the screw locks in place, but it will follow the batch. Rotate so that objects are not tightly occluded. The main reason is that the lock is not released in time, and the time is too long; if the hand is not released in time after locking, the time is too long; if the torque is too large, the sliding wire will be tightened after locking in place.
The solution is to lock it in place, release it in time or replace it with a screw of the appropriate diameter; the phenomenon of peeling paint and flowers on the screw head is that the screw is painted black. The paint on the surface was worn away, revealing silvery-white metal. The main reason is that the batch head is not perpendicular to the screw and is ground. Flower metal finish (grinding); the solution can be vertical bit and screw; the phenomenon of not locking in place, that is, after the wind batch is locked, it will automatically stop or rotate slowly, but the screw is not completely locked, leaving a gap. The main reason is that after unlocking it, it has stopped. time is too short. Torque is too low. The solution is to increase the torque and make sure the screw locks in place, after that, you can let go.
