Further characteristics as the invention, described elastic locking spare comprises sleeve pipe, spring and hoodle, sleeve pipe is installed on the notch of U-shaped bracing frame, spring is arranged in the sleeve pipe, hoodle is separately positioned on the spring both sides, the bulb of hoodle stretches out the U-shaped bracing frame, and the bulb of hoodle cooperates with folding spacing hole when the table pin is folding, cooperates with the support limit hole when the table heel brace leaves.

After adopting said structure, the invention has following advantage:

The one, when folding table struts, the bulb of hoodle puts in the support limit hole, U-shaped bracing frame and two support bars are on the same straight line, play desktop and the effect that is connected, supports of table pin, the support limit notch of U-shaped bracing frame is buckled on the support limit pin of support bar, and when the table pin was subjected to external force, the table pin can not produce toward interior contraction, therefore, folding table can not cause the desk overturning owing to the effect of external force in use.

The 2nd, in handling process, the table pin is in folded state, at this moment, the bulb of hoodle puts in the folding spacing hole, and the support limit pin drops in the folding groove, and the U-shaped bracing frame overlaps with two support bars, because the elastic force effect of spring, the bulb of hoodle can not deviate from folding spacing hole, even be subjected to the effect of external force, the table pin can not strut yet, thereby can guarantee the reliability that a pin is folding, therefore, table pin folding when carrying can not launch suddenly, causes unnecessary harm.

The 3rd, because the folding table locking that struts and fold realizes by spring and hoodle, cancelled the structure that adopts locating ring off, so the paint on U-shaped bracing frame and two support bars can not wiped, do not get rusty with regard to not causing;

The 4th, folding or when strutting pin, pull a pin with hand and just can realize folding and strut, therefore easy and convenient when operation, point and also can not pressed from both sides;

The 5th, simple and compact for structure, elegant in appearance.
