[0005] Preferably, the front end of the dust cover is arc-shaped structure, the rear end of the dust cover is plane structure, the guide wheel is located at the both sides of the rear end of the dust cover.

[0006] Preferably, the adjusting piece is the columnar structure that lower end diameter is big and upper end diameter is small, and the upper end of the adjusting piece is inserted in the installation cavity.

[0007] Preferably, the both ends of the screw are inserted through plug-in barrel, the lower end of plug-in barrel and the upper end of adjusting piece, and the lower end of the screw is screw-connected with the adjusting piece.

[0008] Compared with the prior art, the beneficial effects of the utility model are that the guide wheel is abutted against the wall, the movement of the dust cover can be guided through the cooperation of the adjusting part and the spring, when different structure skirting lines are encountered, when the guide wheel is abutted against the wall, the adjusting part is fixed in position through the rotating screw, thereby the rotating angle of the eccentric plate is controlled, the position of the guide wheel is controlled, the distance between the grinding sheet and the skirting line is ensured, different state skirting lines are adapted, the wall and the ground connection ground are conveniently ground, and the ground can be ensured to be entirely covered. BRIEF DESCRIPTION OF DRAWINGS

[0009] Fig. 1 It is a dust cover three-dimensional structure schematic view.

[0010] Fig. 2 It is a dust cover connecting sectional view.

[0011] In the drawing: 1 dust cover, 2 guide wheel, 3 screw, 4 eccentric plate, 5 installation cavity, 6 spring, 7 plug-in barrel, 8 adjusting part. DETAILED DESCRIPTION

[0012] In order to deepen the understanding and the realization of the utility model, the technical scheme in the utility model embodiment will be clearly and completely described and introduced in combination with the drawings in the utility model embodiment, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment, and does not limit the embodiment in any form. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0013] Please refer to Figs. 1-2 The utility model provides a kind of technical scheme: a adjustable grinder dust cover, including dust cover 1, the middle of dust cover 1 is equipped with cavity, dust cover 1 one end is equipped with two guide wheels 2, the inside middle of dust cover 1 is equipped with installation cavity 5, installation cavity 5 is equipped with adjusting part 8, adjusting part 8 is sleeved with spring 6, one end of spring 6 and adjusting part 8 are fixedly connected, the other end of spring 6 and installation cavity 5 inner wall are fixedly connected, adjusting part 8 is inserted with plug-in barrel 7, plug-in barrel 7 is screw-threaded with screw 3, plug-in barrel 7 outer side wall is fixedly connected with eccentric plate 4, eccentric plate 4 upper end surface and guide wheel 2 are rotatably connected, the front end of dust cover 1 is arc structure, dust cover 1 rear end is plane structure, guide wheel 2 is located dust cover 1 rear end both sides, when guide wheel 2 is abutted against the wall, spring 6 will be compressed, spring 6 because of its own elastic force control guide wheel 2 is always abutted against in wall, the movement of dust cover 1 is guided.
