Abstract: A fluid magnetization straw includes a hollow tube adapted as an outer tube, and at least one magnetizing member. A magnetizing member retaining end and a tube joint are configured at a minimum of one extremity of the outer tube, thereby containing the magnetizing members within the outer tube, facilitating dismantling for cleaning, and connective linkage with other application facilities and devices. At least one magnetic core structured to include a permanent magnet is configured within each of the magnetizing members. Moreover, an annular channel is formed between the magnetizing members and an inner wall of the outer tube thereof. Because of a special assemblage of the permanent magnets of the magnetic core within the magnetizing members, lines of magnetic force from such approach an inner wall in a tangential fashion through a fluid of an annular channel, thereby realizing a good fluid magnetization and ionization effect.

Abstract: A box structure for fixing folding bicycle comprises a positioning device comprising a body member being connected to fold bicycle and a positioning member; and a box device comprising a body locating a chute in one side that being connected to a draw bar means and a positioning hole which providing to fasten to said positioning device by plunging said positioning member.

Abstract: A compact folding handle bar apparatus for a bicycle is provided. The folding handle bar apparatus includes a first handle bar and a second handle bar each having formed thereon a handle holder. Each handle holder is formed with a hollow body configuration and has transversely projecting therefrom a pair of connecting members separated one from the other by a gap. A pin is pivotally coupled to extend between the connecting members of the first handle bar. The folding handle bar apparatus also includes a stem coupled to the first and second handle bars, as well as a control screw device coupled to the pin through the gap between the connecting members of the first handle bar. The control screw device is displaceable with the pin between fastening and releasing positions relative to the first and second handle bars. In the fastening position, the control screw device extends at least partially through the gap formed between the connecting members of both the first and second handle bars.

Abstract: A foldable bicycle pedal crank, comprising a crank, a crank endpiece, a lock, and a pedal. The crank has a connecting yoke, passed through by a first crank hole and second crank holes which aim across an indentation thereof. The crank endpiece has an insertion part that is inserted in the indentation, with a first hole, second holes and a third hole passing through the insertion part. The lock further comprises a lock body, at least one first bolt and second bolts. The first and second bolts have outer ends connected with the lock body. The first bolt further has an inner end and is hollow, enclosing a space that towards the inner end is limited by a step and accommodates a rod. The rod has a far end that passes through the inner end of the first bolt and is fixed. A spring surrounds the rod, leaning against the step. The pedal is connected with the crank endpiece.
