Patent attributes
A clamping device includes first and second clamping components and at least one elastic component. The first and second clamping components include first and second rear portions and first and second front portions pivoted to each other respectively. The first and second rear portions are pivoted to each other. The elastic component connects the first and second clamping components. The first and second clamping components rotate, with respect to each other, to a first state due to an elastic force of the elastic component so that the first and second front portions have a first distance. When the first and second clamping components are subject to a force, the first and second clamping components resist the elastic force of the elastic component and rotate, with respect to each other, to a second state so that the first and second front portions have a second distance greater than the first distance.
