1. Field of the Invention
The present invention relates to a folding device and, in particular, to a folding device able to be mounted on a vehicle for folding and/or locking front and rear frames of the vehicle.
2. Description of the Related Art
In order to save storage space and facilitate carrying, the current trend is to build folding vehicles, such as folding bicycles or electric folding bicycles, and in order to meet different requirements in respect of folding, various folding devices have been designed on the foldable vehicles, among which folding, unfolding and locking devices are the most commonly used.
Further, the conventional folding device substantially includes two linking members and a quick release skewer. The two linking members are respectively jointed to front and rear frames of the folding vehicle by welded or other connection means, and the two linking members are pivotally connected with each other by means of a suitable mechanism. The quick release skewer includes a rod threaded on one end and with a lever operated cam assembly on the other. The rod is inserted into the two linking members, a nut is threaded on, and the lever can be closed to selectively tighten the cam and secure the two linking members to each other.
However, when the two linking member are intend to pivot with each other for folding, a user must open and rotate the lever and then pull the rod out from the two linking members to loosen the cam. The operation of the conventional folding device is monstrously complicated, and the connection strength between the two linking member is not strong enough.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
