Abstract: An air gun with a quick-releasing device has a body, a head tube attached to the body and a detachably functional tip, wherein the quick-releasing device is attached to a distal end of the head tube to secure the detachably functional tip. The quick-releasing device has a slit defined in the distal end of the head tube to communicate with an inner space of the head tube, a locking sheet movably received inside the slit to partially enter the inner space of the head tube, and a locking lever pivotally mounted on the head tube to drive the locking sheet to move in a vertical direction. Thereby, the locking sheet is allowed to leave the inner space of the head tube when a user presses the locking lever to enable easy release of the attached functional tip and then to exchange the original tip for another functional tip.

Abstract: Method and material for manufacturing cold/hot elastic gel, in which synthesized vegetal glue and high order starch are mixed at a certain ratio and fully stirred into an even state. Then a certain amount of water is added into the mixture and stirred to an even state to produce flour mash-like sticky mass by various processing tools or human hands. The solution is at the same time heated to a certain temperature. During heating, the chemical bonds of the molecules of the materials are chemically changed to form thermally irreversible gel. The materials are blended into flour mash-like sticky mass. After rested and cooled, the sticky mass processed by various processing measures into gel foods which can be frozen and refrigerated. The elasticity of the gel foods in hot state is equal to the elasticity of the gel in cold state. The gel foods can be further steamed or cooked for eating.

Abstract: A bi-directional compressed air outlet includes a tubular body having a handle which has a chamber and a passage defined therein, and a valve device disposed to the handle and communicating between the chamber and the passage. A middle member is movably received in the body and has a plurality of inclined apertures defined therethrough. The body has an annular inclined flange defined in an inner periphery thereof and the middle member has an annular inclined surface defined in a front end thereof so as to mate with the inclined flange. Air in the chamber proceeds through the passage and selectably toward a front end of the body via a space defined between the inclined flange and the inclined surface, or a rear end of the body via the inclined apertures.

Abstract: An adjustable illuminating/retrieving apparatus comprising a flexible structure having a first end portion and a second end portion connected with a first end portion of an extension tube which includes a second end portion with a magnet fixedly mounted therein. A supporting base extends outward from the first end portion of the extension tube and is pivotally connected with a pivot base. A receiving tube includes a first end portion mounted on the pivot base and a second end portion formed with a first annular flange extending outward. A lighting unit is received in the receiving tube and partially extends outward of the second end portion of the receiving tube. A sliding sleeve is slidably mounted on the receiving tube and includes a first end portion formed with a second annular flange extending inward.
