Abstract

A clamping device for mobile phones includes a fork-shaped link pivotally connected to a clamp seat at either end. Each clamp seat has a lateral side provided with slanting rack teeth. An elastic securing seat is disposed adjacent to the rack teeth and has stop elements for projecting into the rack teeth to force the clamp seats to displace only inwardly to be positioned in place. The securing seat further has slanting notches at its ends. A press rod provided with corresponding slanting notches is passed through the notches of the securing seat. By pressing the press rod, the securing seat is urged to displace rearwardly, bring the stop elements to disengage from the rack teeth. Due to the action of compression springs, the clamp seats are caused to instantly extend to clamp mobile phones of various sizes and types.

Claims

1. A clamping device for mobile phones, comprising:

an upper base and a lower bases;

a clamp seat disposed on two opposite sides of said upper and lower bases in the form of pawls, each having a side portion provided with a pad, said clamp seats each having a lateral side provided with a plurality of slanting, unidirectional rack teeth;

each clamp seat is respectively pivotally connected to ends of a fork-shaped link on said upper base;

a plurality of compression springs disposed between said clamp seats, urging said clamp seats away from each other;

an elastic securing seat disposed on said upper base adjacent to said rack teeth on said clamp seat, said securing seat having a plurality of stop elements, at least one stop element engaging the rack teeth on each of said clamping seats for restraining said clamp seats so as to be displaceable only inwardly toward each other, said securing seat further having first slanting notches at ends;

a press rod passing through said notches, said press rod having second slanting notches at corresponding positions to said first slanting notches; and

a press rod spring acting on the press rod whereby movement of the press rod against the press rod spring causes the plurality of stop elements to disengage from said rack teeth, thereby allowing the plurality of compression springs to move the clamping seats away from each other.

2. The clamping device as claimed in claim 1, further comprising a clearance formed between said side portions of each clamp seat to facilitate arrangement of electrical wires for connecting mobile phones.
