A container for storing multiple saw blades includes: a base, a cover and a plurality of positioning units. The cover has one side pivotally fixed to the base, another side clasped to the base by a clasp, and a covering portion between the two sides of the cover. The covering portion is smaller than the base. The positioning units each include a stop piece and a central positioning block which are disposed on the base in a spaced manner. The stop pieces are located at different distances from the peripheral wall and have different heights with respect to the bottom of the base, the heights of the saw blades are proportional to the distances of the stop pieces to the peripheral wall of the base, and the central positioning blocks are disposed on the covering portion or the base.

A tool box includes two pivoted halves, at least one of which has a chamber with a bottom and two opposite walls. Plural positioning units are disposed on the walls and each include a straight guide groove, a guide gap and a positioning cavity at two ends of the straight guide groove, a first pivot cavity located closer to the bottom than the positioning cavity, a second pivot cavity between the positioning cavity and a positioning cavity of a neighboring positioning unit, and an arc-shaped guide groove covering the first and second pivot cavities. The arc-shaped guide groove has two arc-shaped ends to connect the first pivot cavity and a straight guide groove of the neighboring positioning unit. The storage member has pivots pivotally disposed in the first pivot cavity and the positioning cavity, or in the first or second pivot cavity of the neighboring positioning unit.

A stepped elastic positioning structure for a semiconductor carrier includes a plurality of transversely and longitudinally arranged walls and a plurality of recesses defined by the walls. On the walls of the semiconductor carrier is formed a plurality of L-shaped stop blocks, each of the stop blocks has an elastically deformable free end which is capable of elastically restricting the semiconductor in the recess, and improving the easiness for putting in or taking out the semiconductor. The end of each of the stop blocks is a stepped structure, plus the elastic deformability of the stop blocks, which makes the recess capable of holding different sized semiconductors.

A reel type cold light warning triangle includes a base, two support members, a cold light reel assembly, an elastic return assembly, two support units, a pulling member, a power system and a control assembly. The cold light warning piece can be pulled out or rolled up automatically simply by pulling or pushing the pulling member without using any assembling or disassembling tools, which is very convenient. Furthermore, the base provides stable support for the reel type cold light warning triangle. On top of that, the warning triangle is provided with the power system which can generate enough power to satisfy the power consumption of the cold light warning triangle, and the vehicle-electric-appliance plug can supply power from vehicle to the cold light warning triangle if the power system cannot generate enough power.

A grease gun with a quick-release end cover includes a barrel, and an operating end cover and a piston end cover disposed at two ends of the barrel. Between the operating end cover and the barrel is disposed a quick-release device which includes: an annular groove formed around the barrel; a first hole formed in the operating end cover and includes an outer open end and an inner open end. Inside the first hole is formed an annular shoulder portion, in the outer open end of the first hole is formed a slot. A control member has a shaft inserted into the first hole, the shaft includes an abutting and an operating portion formed at two ends thereof, and a positioning pin. A compression spring is sleeved onto the shaft and pressed between the annular shoulder portion of the first hole, and the annular abutting portion of the abutting block.
