<p>A structure connecting a handle horizontal tube on a folding handle is provided with a support sleeve to be rotary connected to the handle horizontal tube, and has a square core pin, the square core pine being adapted to a square hole disposed on the support sleeve. The support sleeve moves on the square core pin, a restoring spring is disposed on the square core pin and located at a bottom of the support sleeve, a straight pin is inserted in a spring position hole disposed at the lower part of the square core pin, so as to fix the position of one end of the restoring spring. In this way, the support sleeve, the restoring spring and the straight pin may construct a structure having an elastic function, so as to facilitate the folding of the handle. The present invention provides a suitable device for the production of a handle of a folding bicycle.</p> |
