Abstract: A clothes hanging stand device mainly has a pair of vertical stand oppositely facing with each other, several frames connecting the pair of vertical stand and a shelf stand set up in the hanging space formed by the pair of vertical stand. The expansion or contraction of the shelf stand can provide an enlarged two-level hanging space, or a full height hanging space for apparel. Furthermore, the hanging space can be further expanded to the outside of the pair of the vertical stand by the extending of an extending rod of the horizontal oriented frame. Quick assembling and disassembling among the components can be achieved. Additionally, the whole device after collapse takes little volume space for easy store-up.

Abstract: The present invention relates to a device for actively threatening extrinsic destruction of a lock which is formed by a male member and a female member, wherein the device comprises a plurality of container units formed by rigid and brittle materials, such as plastic or glass materials and having a pressurized tear gas or toxic gas filled therein to form sealed structures that are inserted in a space in the female member or the male member, and several alarming marks or characters are marked on a surface of the lock. In such manner, when the lock is subjected to an extrinsic destruction, the deformation of the female member or the male member resulted from the extrinsic destruction will squash the sealed container units to instantly eject the pressurized tear gas or toxic gas out.
