Detailed Description
In order to make the technical means, the original features, the achieved objects and the effects of the present invention easily understood, the following embodiments will specifically describe the movable steel belt clip assembly according to the present invention with reference to the accompanying drawings.
< example >
As shown in fig. 1 and 2, a movable steel band clip assembly of the present embodiment includes: the steel belt clamping device comprises a frame 9, an eyelet bolt 5, a pin shaft 6, a spring 3, a nut 2, a top bolt 1, a steel belt clamping body 7, a steel belt clamping head 8 and a steel belt 11.
The frame 9 is provided with a through hole, and the upper end of the swing bolt 5 passes through the through hole and extends out of the frame. The spring 3 is mounted on the upper end of the swing bolt 5.
