Accompanying drawing explanation
Accompanying drawing described herein is used for providing a further understanding of the present invention, constitutes the part of the present invention, and the schematic description and description of the present invention is used for explaining the present invention, is not intended that inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the sectional view of Burnisher apparatus of the present invention；
Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, a kind of Burnisher apparatus with flexible connecting structure of the present invention, it includes grinding roller head 1 and separator body device 2；Also include one for flexible connecting structure 3 that grinding roller head 1 connects with separator body device 2；This flexible connecting structure 3 includes an axis body 31 and attaching seat 32, and described attaching seat 32 is sheathed for separator body device 2 and connects with securing member 4；Described attaching seat 32, grinding roller head 1 are respectively equipped with and the position, hole 320,10 of described axis body 31 coaxial cooperation；Wherein, on described axis body 31 and be positioned at the diameter of axle of one end of attaching seat 32 more than the diameter of axle of the other end；Axis body 31 two ends respectively penetrate and are tight with at described attaching seat 32 and the position, hole 320,10 of formation in grinding roller head 1, so that grinding roller head 1 and described separator body device 2 are removably attached to one.
More specifically, also include axle sleeve 5, the axle sleeve 5 that axle sleeve 5 is made for flexible material；This axle sleeve 5 is respectively installed in the position that axis body 31 two ends are connected with attaching seat 32, grinding roller head 1；The axle sleeve 5 being positioned at described grinding roller head 1 place extends a crashproof portion 51A to attaching seat 32 direction, and it is located between cascaded surface 50 and the grinding roller head 1 that axis body 31 two ends are formed.
Detailed description of the invention, a kind of Burnisher apparatus with flexible connecting structure of the present invention, it mainly includes with lower component: grinding roller head 1, separator body device 2, axis body 31, attaching seat 32 and axle sleeve 5；
