[0037] The output end of the driving member is downward, the second rotating rod takes the position hole as the rotation point, and the second rotating rod is bent toward the central axis of the fixed dust collector to form a clamping action;

[0038] Step 7: The driving member retracts, the second rotating rod returns to a state parallel to the slide groove, the rear connecting spring is compressed and contracted, the connecting block is installed in the side groove, and the rear rotating rod slides upward along the side groove to the initial position;

[0039] The driving member drives the rotating sleeve upward to point A, and then the driving member continues to return upward to the origin.

[0040] Beneficial effects:

[0041] The present invention provides a second rotating rod that slides on the dust cover, and a connection piece and a position hole provided on the top enable a rotation function, thereby enabling the rotation of the second rotating rod to realize the clamping action. When not in use, the second rotating rod is installed on the outer end of the fixed dust cover, without affecting the normal operation of the breaker and dust suppression spraying. This allows the fixed dust cover to have both dust suppression and clamping functions.

[0042] The present invention forms water flow through a complete water storage tank, a water outlet pump and a water diversion pipe. Secondly, the fixed dust removal cover is conducive to reducing the dust-raising area and the filter layer at the bottom can isolate most of the dust, preventing the work of the drill rod from being affected by dust accumulation.

[0043] The present invention provides a connecting block that is inserted into the position hole and is supported by a connecting spring and is conical, so that the second rotating rod can be moved and rotated, and the rotation direction can be changed. Moreover, because of the connecting spring, it can be reset and slide into the side groove again.

[0044] The present invention realizes expansion of the spray range and achieves the effect of easier dust reduction by arranging multiple spray heads on the spraying member. BRIEF DESCRIPTION OF THE DRAWINGS
