Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail. It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention.
As shown in Figures 2 and 3, the present invention provides a kind of glass substrate edge wheel, including edge wheel body 10, wherein, edge wheel body 10 includes first paragraph edge wheel body 11, second segment edge wheel body 12 and the annular groove 13 being connected between first paragraph edge wheel body 11 and second segment edge wheel body 12, annular groove 13 is circumferentially extending along edge wheel body 10, the outer peripheral face of first paragraph edge wheel body 11 is provided with and draws heel teeth 21, the outer peripheral face of second segment edge wheel body 12 is provided with annular continuously and draws limit fin 22, annular draws circumferentially extending along edge wheel body 10 of limit fin 22, and draw the tooth top of heel teeth 21 to draw the outer radius of limit fin 22 more than annular to the distance of the central axis of edge wheel body 10. in other words, the tooth top drawing heel teeth 21 protrudes from annular and draws limit fin.
