A track system may include a track assembly and a support assembly. A track assembly may include a toothed portion. The support assembly may include a support member removable from and adjustably connected to the track assembly. The toothed portion may include a plurality of track teeth. The support member may include an adjuster pinion. The adjuster pinion may include a plurality of pinion teeth configured to engage the plurality of track teeth. The adjuster pinion may be adjustable to an engaged position in which the adjuster pinion and the toothed portion are engaged with one another. The adjuster pinion may be adjustable to a disengaged position in which the adjuster pinion and the toothed portion are not engaged with one another.

A lighted artificial tree includes a first tree portion including a first trunk portion, first branches joined to the first trunk portion, and a first light string. The first trunk portion has a trunk connector and a first trunk wiring assembly, the first trunk wiring assembly is electrically connectable to the first light string and the trunk connector, and at least a portion of the first wiring assembly is located inside the first portion. The second tree portion includes a second trunk portion, second branches, and a second light string. The second trunk portion has a trunk connector and a second trunk wiring assembly, the second trunk wiring assembly electrically connectable to the second lighting string and the trunk connector. The second tree portion may be mechanically coupled and electrically connected to the first tree portion by coaxially coupling the first trunk portion to the second trunk portion.

The present invention discloses a lamp, which comprises a lamp seat installed in a base. The lamp seat is electrically connected with a circuit board. At least one USB interface includes a cartridge disposed in the base and a USB socket module disposed inside the cartridge. A wall of the cartridge, which is corresponding to the socket of the USB socket module, has at least one opening. The interface of an external USB data line can be passed through the opening and inserted into the socket of the USB socket module. The USB socket module is separated from the circuit board and electrically connected with the circuit board through cables. Therefore, the USB interface is reduced to a smaller size and requires less space for installation. Thus, the position for installing the USB interface has higher selectivity, and the overall esthetics of the base is improved.
