Abstract: This present invention is an improved structure of slide rail latch for device cabinet, which includes: at least one slide rail fixing frame with a locking plate on its front end, and a locking base plate with upper and bottom locking ends on both sides. The locking base plate is composed of at least one latching hole, one locking pin and one latching fastener, which includes one latching base plate with upper and bottom latch bending side edges on both sides. This latching base plate is composed of at least one locking hook and locking hole which are correspondent with latching hole and locking pin respectively. The latch bending side edge includes a hook on its front end. Thus this invention will make the fixing frame of slide rail can be easily manufactured in all-in-one process, and more convenient and timesaving in assembly to improve economic benefit for assembly manufacturers.

Abstract: A front installing drawer pulling force adjusting apparatus is installed at a front end of a slide. The slide includes a bottom rail, a middle rail and an internal rail. The bottom rail has a latch element at the front end. The bottom rail has a slidable middle rail. The internal rail is embedded onto the middle rail and slid on the middle rail. The front end of the internal rail includes a limit element having a resilient element corresponding to the latch element. The internal rail is connected to an object that needs to be moved. During assembling, a portion intersecting the resilient element in the limit element with the limit element determines the level of retraction of the resilient element to adjust the tightness of clamping the resilient element onto the latch element of the bottom rail, so that users can open a drawer with an appropriate force.

Abstract: An improved structure of a Christmas bulb set having one bulb and one bulb holder as a unit, within, each output end of a pair of conductor filaments of the bulb being compressed into a square pillar shape; a hole penetrating through the center of the bulb holder allowing both ends of the square pillars to complementary attached to each other; and both positive and negative terminals connected with a wire at their lower ends being inserted into opposite side walls next to the hole characterized by that a circumferential groove being provided to the upper part of the square pillar of the bulb, the filaments being curved by compromising the opposite walls of the square pillar; a flange merely to receive insertion by the bulb groove being extended inwardly from the upper circumference of the hole on the bulb holder with the inner diameter of said flange not greater than the outer diameter of the circumference of the bulb groove to allows direct conduction of the electric circuit with the bulb well secured and pr
