BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to an improved luminescence wheel axle assembly, more particularly a wheel axle having an improved luminescence assembly mounted on the wheel to accomplish the effects for the overall luminescence of the wheel and safe driving at night.  
         [0003]     2. Description of the Prior Art  
         [0004]     In general, a regular wheel does not come with a warning device. At present, the market has some wheels with reflective warning devices installed on the spoke cable, and such reflective warning device is the traditional warning device that makes use of the light reflection to accomplish an effect for safe night driving. Some wheels have warning devices installed between both sides of the axle of the wheel to accomplish such safety effect, but their installation and removal are not simple and easy, and thus have the shortcomings of complexity and inconvenience.  
       SUMMARY OF THE INVENTION  
       [0005]     The primary objective of the present invention is to provide an improved luminescence wheel assembly comprising a latch base coupled to a plastic optical fiber structure installed on both sides of the wheel axle, such that the product is easy to install, easy to remove, and aesthetically pleasing. The present invention can also accomplish the purpose of driving safely at night.  
         [0006]     The secondary objective of the present invention is to provide an improved luminescence wheel assembly capable of adjusting the size of its structure according to the size of the wheel axle, which can fit different sizes of wheel axles.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0014]     Please refer to FIGS.  1  to  5  for the luminescence wheel axle assembly in accordance with this invention, comprising a latch base  1 ′, a ratchet bolt structure  5 , and a plastic optical fiber structure  3 ; wherein the latch base  1 ′ has a circular hole  41  at its center for facilitating its being mounted on to an axle  4  of a wheel W, and the latch base  1 ′ comprises an upper latch base  1  and a lower latch base  2 , and the upper latch base  1  comprises an upper casing  11 , a lower casing  12 , a plurality of screw holes  111  disposed on the upper casing  11 , a receiving rotary axle  5 ′ disposed at the left lower end surface of the lower casing  12 , a ratchet bolt structure  5  disposed on the right end surface, and the lower latch base comprising an upper casing  21 , a lower casing  22 , a plurality of screw holes  211  disposed on the upper casing  21 , a rotary axle  5 ′ disposed on the upper left end surface of the upper casing  21 , and a ratchet  221  on the right end surface of the upper casing  21 . The rotary axle  5 ′ has a rotary end surface  51 ′ for the support and is inserted into the receiving rotary axle  5 ″ for pivotally coupling the upper latch base  1  and the lower latch base  2 , and further comprises a plurality of insert holes on the lateral end surface of the latch base  1 ′ for receiving the insertion of the plastic optical fiber structure.  
         [0015]     Further, refer to  FIGS. 2, 3 , and  5 . In the figures, the ratchet bolt structure  5  disposed on the right end surface of the upper latch base  1  comprises a control post  51 , a fixed ratchet plate  52 , a spring  53 , and a fixed plate  54 , and installed into the opening at the lower right end surface of the latch base  1  in sequence, wherein the opening of the fixed plate  54  fixes the fixed ratchet plate  52 , and installs a fixed base  521  for latching or separating the fixed ratchet plate  52 . In  FIG. 3-1 , the ratchet  221  at the right end surface of the lower latch base  2  is latched into the upper latch base  1 , and the control post  51  of the ratchet bolt structure  5  pulls its spring  53  upward and then pushes it towards the ratchet  221  to fix the ratchet plate  52  onto the teeth of the ratchet  221 , so that the upper latch base  1  and the lower latch base  2  are secured onto the wheel axle  4 . In  FIG. 3-2 , if it is necessary to separate the ratchet  22  on the right end surface of the lower latch base  2  from the upper latch base  1 , its control post  51  of the ratchet bolt structure  5  is pressed downward, so that the fixed ratchet plate  51  is separated from the ratchet and presses against the spring  53 . In other words, the fixed ratchet plate  52  is separated from the teeth of the ratchet  221 , such that the upper latch base  1  and the lower latch base  2  can be separated from the wheel axle  4 .  
         [0016]     Please refer to  FIGS. 1, 2 , and  5 . In the figures, a base  31  disposed at the bottom of the plastic optical fiber structure comprises a luminescence structure  311  and a plastic optical fiber  32  coupled to the top of the plastic optical fiber structure. The latch base  1 ′ comprises a battery and a lid  13 , a cable and a control circuit board  24 , and a switch button  23 . When the plastic optical fiber structure  3  is inserted into the insert hole  6  to connect the power supply for driving the plastic optical fiber to produce a luminescent effect, and also works together with the connection between the upper latch base  1  and the lower latch base  2  to install the luminescence wheel axle assembly on both sides of the axle of the wheel and accomplish the effects for the safety of night driving and the artistic appearance.
