Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that this description is intended to be exemplary, and not to limit the scope of the invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1-2, the utility model provides a self-adaptation unwrapping wire corner coaster, include:
the support comprises a support 1, fixed rollers 8, movable rollers 9 and a support plate 3, wherein the support 1 is provided with side support plates 2, the fixed rollers 8 are connected with the middle parts of the side support plates 2 through rotating shafts, the movable rollers 9 are positioned at two sides of the fixed rollers 8, the movable rollers 9 are provided with triangular supports 10, the triangular supports 10 are connected with the movable rollers 9 through rotating shafts, sliders 5 are arranged on the outer sides of the triangular supports 10, the side support plates 2 are correspondingly provided with strip-shaped sliding openings 4, elastic rods 11 are arranged on the bottom surfaces of the triangular supports 10, the support plate 3 is welded between the supports 1, the support plate 3 is provided with a plurality of through holes, the elastic rods 11 penetrate through the through holes, one ends of the elastic rods 11 are welded on the bottom surfaces of the triangular supports 10, one ends of the elastic rods are provided with elastic caps 13; the support 1 is L-shaped, and the side support plate 2 is arc-shaped; the support 1 is provided with a semi-circular rod 6, two ends of the semi-circular rod 6 are respectively welded at two ends of the support 1, the side support plate 2 is uniformly provided with a plurality of support rods 7, one end of each support rod 7 is welded on the side support plate 2, and the other end of each support rod 7 is welded on the semi-circular rod 6; the supporting plate 3 is V-shaped, and the triangular support 10 is parallel to one surface of the supporting plate 3.
