Abstract:
A clamp for fixing a small electronic device on an upper end of a rectangular panel. The upper end of the panel has a horizontal top end, a front edge and a rear edge, the front and rear edges being perpendicular to the top end of the panel. The clamp includes an L-shaped assembly, an elastic module, and a base. A vertical side at the front of the L-shaped assembly engages the top end and the front edge of the panel. An elastic module fixed at a rear end of the L-shaped assembly has an arc-shaped plate bending towards the rear edge of the panel so that the L-shaped assembly will attach tightly to the top end and the front edge of the panel. The base is fixed on the L-shaped assembly and is used to fix the small electronic device. When mounting the clamp to the upper end of the panel, the upper end of the panel will slip across the arc-shaped plate and be clamped between the arc-shaped plate and the L-shaped assembly of the clamp.
