The outer wall of the lever 97 is slidably connected to the inner wall of the back side of the movable disk 92, and the sliding effect of the lever 97 drives the block 96 to slide.

[0040] Reference Figure 1 The inner wall of the dust collector head 81 is rotatably connected to the outer periphery of the fixing frame 82. The dust collection angle of the dust collector head 81 is adjusted by the rotation effect of the dust collector head 81. The top rear end of the dust collector head 81 is hinged to the bottom end of the hinge rod 851. The dust box 84 is fixedly connected to the front side of the shell 1. The dust box 84 is prevented from falling off by the fixing effect of the dust box 84.

[0041] Reference Figure 5 The outer wall of the block 96 is slidably connected to the inner wall of the movable disk 92. Through the sliding effect of the block 96, the block 96 and the slot 93 are engaged or released. The outer wall of the block 96 is engaged with the inner wall of the slot 93. Through the engagement effect of the block 96 and the slot 93, the rotating shaft 7 limits the movable disk 92.

[0042] Working principle: When the staff needs to perform milling work on the road surface, the staff starts the motor 2 to drive the cylindrical rod 10 to rotate, so that the pulley A5 drives the pulley B6 to rotate through the belt, thereby driving the rotating shaft 7 to rotate, so that the fixed disk 91 and the movable disk 92 drive the milling cutter 4 to rotate, and the road surface is milled. The staff uses the handrail to push the shell 1 for mobile milling.

[0043] At the same time, the dust collector 81 is started, and the gear B858 is driven to rotate by the rotation of the cylindrical rod 10, and the gear A857 is driven to rotate by the gear B858, so that the cylindrical shaft 855 is rotated, thereby driving the cam 856 to rotate, and the connecting rod 854 is reciprocating, thereby driving the slide plate 852 to slide back and forth vertically along the outer periphery of the guide rod 853, so that the hinged rod 851 drives the dust collector 81 to flip up and down reciprocatingly along the outer wall of the fixed frame 82, and the dust generated during road milling is sucked by the dust collector 81 that flips up and down reciprocatingly, and the sucked dust is transported to the dust box 84 through the connecting pipe 83 for collection.

[0044] When the milling cutter 4 is damaged after long-term use, the staff can toggle the lever 97 to release the clamping effect of the block 96 on the clamping slot 93 and release the limiting effect on the movable disk 92, and slide the movable disk 92 to the back of the shell 1, so that the socket 94 on the movable disk 92 is released from the plug-in effect of the milling cutter 4. The staff can remove the milling cutter 4 from the fixed disk 91, plug the replaced milling cutter 4 into the socket 94 set on the fixed disk 91, and slide the movable disk 92 to the front of the shell 1, so that the socket 94 set on the movable disk 92 is plugged with the replaced milling cutter 4, and release the lever 97, so that the clamping block 96 is clamped with the clamping slot 93 under the elastic force of the spring 95, and at the same time, the movable disk 92 is limited, so that the milling cutter 4 remains fixedly installed on the fixed disk 91 and the movable disk 92.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
