Abstract: An electric spreading device for a parasol includes an inner tube, an outer tube, a handle and an electric motor. The inner tube has an upper end extending through a lower sleeve of a lower ring and fixed with an upper sleeve of an upper ring, with a screw having a center threaded hole fixed in a lower end of the inner tube. The outer tube fits around the inner tube to enable the inner tube to move up and down, having its upper end fixed with the lower sleeve and its lower end connected with the handle. The motor is arranged in the handle, having a threaded rod to engage the center threaded hole of the screw of the inner tube. Then the motor with the threaded rod rotates relative to the screw so that the inner tube with the screw can be moved up and down for spreading or collapsing the canopy.

Abstract: A parasol with a light device includes a light device, a power source and a power switch respectively connected with wires. One ends of the wires are respectively connected with a male and a female connector, and the male and the female connector are possible to fit with or separate from each other. When the male and the female connector are fitted with each other, the two sets of the wires get connected with each other. If the light device is to be replaced with new one owing to disorders, first the male connector and the female connector are separated from each other, then the light device is separated from the power switch for replacing. And the power source is a chargeable battery, enabling the parasol with the light device used anywhere.

Abstract: A possible-to-sway fence connector includes a fix base and a movable base. The fix base is fixed on a vertical side of a post of a fence, having two studs with a pivot hole at a right and a left side. The movable base has a rear convex sidewall with a horizontal pivot hole and two studs with a pivot hole. Then an end of a transverse tube of a fence is combined with the movable base in such a way that the transverse tube may sway to the right and the left side. Further, the movable base is positioned in the fix base by means of a horizontal pivot extending in the pivot hole of the movable tube. Thus, movable base can swing up and down with the horizontal pivot relative to the fix base, and the transverse tube can swing to the right and the left side so that units of a fence between two posts can be adjusted in mutual angles up and down, and right and left.
