The number of the tooth claws and the number of the open slots are two, and the tooth claws are respectively positioned in the corresponding open slots.
The rotary body, the adapter and the dust collection interface are all cylindrical, and the end part of the dust collection interface is in a necking shape.
The adapter is rotationally connected with the flange through two bearings, and the bearings are deep groove ball bearings.
By adopting the structure, the invention adds the adapter body on the basis of the original structure, the adapter body is rotationally connected with the flange through the bearing, and when the cylinder piston drives the rotating body to rotate, the rotating body drives the adapter body to rotate, so that the friction between the adapter body and the flange is reduced, and the friction force of the rotary sealing piece arranged at the joint of the adapter body, the dust collection interface and the flange is reduced. And because the other end of the rotating body is provided with an open slot, one end of the adapter body is provided with a tooth claw inserted in the open slot. The tooth claw can slide in the open slot, when the chuck clamps and loosens the switching tool, the oil cylinder piston needs to move axially, the axial movement is ensured between the rotating body and the adapter, and the radial movement of the rotating body and the adapter is limited. The rotary sealing ring is arranged between the rotary body and the adapter body, and the rotary sealing ring is added, so that the rotary vacuum cleaner has a good sealing effect, reduces the loss of negative pressure air and improves the dust collection effect.
