Preferably, the number of the connecting blocks is six, and connecting holes are formed in the six connecting blocks.

Preferably, the width of the anti-collision rubber block is 5 cm.

Preferably, the length of the connecting block is 6 cm.

Preferably, the four anti-collision rubber blocks are arranged oppositely in pairs.

Preferably, the connecting blocks and the anti-collision rubber blocks are alternately arranged.

Compared with the prior art, the utility model discloses possess following beneficial effect:

the utility model discloses a set up a plurality of anticollision rubber blocks, connecting block, thin fixed rack and thick fixed rack, utilize the mutually supporting between them to can be convenient for install and dismantle, improved the installation effectiveness, secondly the stability of structure obtains the reinforcing, and when suffering unexpected collision extrusion, can carry out collision avoidance to the dust filter framework and dust screen, reduces economic loss, and the practicality is strengthened.
