Construction mixers with keyless chuck

Quick-clamping

— in construction mixers of this type, the nozzle is clamped by rotating a special ring on the spindle, without using any additional tools, keys, etc., only with the help of hands. In some models, for this, the user, however, will have to clamp the first clutch with one hand, and already remove the nozzle with the second. Anyway, it is this solution that ensures the fastest replacement of the nozzle. In some descriptions, the fastener is referred to as Fast Fix or Quick Fix.
