D falling within this range the second mounting portion 12 can be used to mount a more load bearing accessory.
The first mounting portion 11 and/or the second mounting portion 12 are provided in pairs. The first and second mounting portions 11 and 12 provided in pair prevent rotation of the mounted fittings.
The central angle of two adjacent first mounting parts 11 is E, the angle value of E is E, wherein, E is more than or equal to 45 degrees and less than or equal to 60 degrees, for example, the angle E can be set to be 45 degrees, 47 degrees, 50 degrees, 52 degrees, 55 degrees, 58 degrees and 60 degrees. The central angle of two adjacent second mounting parts 12 is F, the angle value of F is F, wherein, F is more than or equal to 45 degrees and less than or equal to 60 degrees, for example, the angle F can be set to be 45 degrees, 47 degrees, 50 degrees, 52 degrees, 55 degrees, 58 degrees and 60 degrees. And the angle bisector of E and the angle bisector of F are in the same straight line.
The angle of the central angle formed by the first bending edge 13 and the center of the nearest second mounting portion 12 is G, wherein G is more than or equal to 10 degrees and less than or equal to 30 degrees, and the angle G can be set to 10 degrees, 12 degrees, 13 degrees, 15 degrees, 17 degrees, 19 degrees, 20 degrees, 22 degrees, 25 degrees, 28 degrees and 30 degrees, for example.
The fastening assembly 21 includes a bolt (not shown) and a nut (not shown) that are engaged with each other; or; the fastening assembly 21 is connected by riveting. When the fastening component 21 adopts a bolt (not shown) and a nut (not shown), the hoop can be detached, so that the maintenance or replacement of parts is convenient; when the fastening assembly 21 is connected in a riveting manner, the connection stability of the fastening assembly 21 is better.
Referring to fig. 4, a second embodiment of a fastening band for preventing the loosening of a band surface mounting screw is different from the first embodiment of the fastening band for preventing the loosening of a band surface mounting screw: the surface counterbore 1112 is stepped recessed. When the surface counter bore 1112 is recessed in a stepped shape, the surface counter bore 1112 is easy to mount and can be well matched with the end shape of the carriage screw 22, and the mounting space is saved.
The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
