After the screw is blown into the mouthpiece, the clamping block can hold the screw thread section well, ensuring that the screw can maintain a good posture when tightening. The structure is more robust and wearable, and can adapt to a certain positional deviation. The screw can be removed directly from the mouthpiece without tools.
·Good thread holding
·High tightening stability
After the screw is blown to the nozzle, the clamping block can hold the screw well, ensuring a good posture when the vacuum is sucked. The head of the suction tube is customized according to the head of the screw to ensure good air tightness and verticality of the screw when sucking the screw. The clamping block is driven by the air cylinder, so that the friction between the suction tube and the clamping block is avoided, and the service life is improved. The nozzles of blow vacuum type and blow clamp type are similar, the difference is that the clamp of blow vacuum is driven by cylinder, to prevent vacuum tube being subjected by lateral force.
·Suitable for compact space tightening
· Good visibility
