Title: Two-section physical-exercise elastic cudgel

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a physical-exercise elastic cudgel, particularly to an easy-to-carry and easy-to-collect two-section physical-exercise elastic cudgel. 
     2. Description of the Related Art 
     The conventional physical-exercise elastic cudgel is used to vibrate away fatness, perform various physical exercises, or function as the toss rod of the Chinese martial art. 
     Refer to  FIG. 4 . The conventional physical-exercise elastic cudgel is a carbon-fiber rod  70  with a handle  71  at the middle and two balance weights  72  and  73  at two ends. The user holds the handle  71  and moves the elastic cudgel up and down repeatedly to induce the vibration of the elastic cudgel. The vibration will feed back to the user&#39;s body to generate effects of exercise, fitness and weight reduction. 
     However, the conventional physical-exercise elastic cudgel is an integral body and unlikely to disassemble. Then, the conventional physical-exercise elastic cudgel always has a considerable length, which makes it hard to package, transport, store, and exhibit for the manufacturers and the sellers, and which also makes it hard to carry and collect for the users. Thus, the user can only use the conventional physical-exercise elastic cudgel at a specified location, which greatly reduces the utility of the conventional physical-exercise elastic cudgel. Therefore, the conventional physical-exercise elastic cudgel has room to improve. 
     SUMMARY OF THE INVENTION 
     As the conventional physical-exercise elastic cudgel is hard to package, transport, store, exhibit, carry and collect, the present invention propose a two-section physical-exercise elastic cudgel to solve the abovementioned problems. 
     The present invention discloses a two-section physical-exercise elastic cudgel comprising a first carbon-fiber rod and a second carbon-fiber rod. The first carbon-fiber rod has a rod body, a first joint end and a first balance-weight end. The first balance-weight end has a balance weight, and the first joint end has a first handle structure. The first handle structure has a handlebar, a male connection block, a supporter and a sleeve ring. The handlebar has a recess, inside which the supporter, the sleeve ring, and the male connection block are sequentially installed. 
     The second carbon-fiber rod has a rod body, a second joint end and a second balance-weight end. The second balance-weight end has a balance weight, and the second joint end has a second handle structure. The second handle structure has a handlebar, a female connection block, a supporter and a sleeve ring. The handlebar has a recess, inside which the supporter, the sleeve ring, and the female connection block are sequentially installed. 
     The first handle structure is connected with the second handle structure via the engagement of the male connection block and the female connection block to form a complete handle, whereby the first carbon-fiber rod and the second carbon-fiber rod form an easy-to-assemble, easy-to-disassemble, easy-to-carry and easy-to-collect two-section physical-exercise elastic cudgel. 
     The supporter of the first handle structure has at least one through-slot, and the supporter of the second handle structure also has at least one through-slot. 
     The male connection block has an external thread, and the female connection block has an inner thread corresponding to the external thread. The first handle structure is connected with the second handle structure via the engagement of the external thread and the inner thread to form a complete handle. 
     Compared with the conventional technology, the present invention has a dismountable two-section design, wherein the first handle structure and the second handle structure are used to form a complete handle, whereby the first carbon-fiber rod and the second carbon-fiber rod are assembled together to form an easy-to-assemble, easy-to-disassemble, easy-to-carry and easy-to-collect two-section physical-exercise elastic cudgel, wherefore is effectively solved the problems caused by too great a length of the conventional physical-exercise elastic cudgel. 
     Below, the embodiments are described in detail in cooperation with the drawings to make easily understood the objectives, technical contents, characteristics and accomplishments of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     Refer to  FIGS. 1-3 . The present invention provides a two-section physical-exercise elastic cudgel, which comprises a first carbon-fiber rod  1  and a second carbon-fiber rod  2 . The first carbon-fiber rod  1  has a rod body  10 , a first joint end and a first balance-weight end. The first balance-weight end has a balance weight  20 , and the first joint end has a first handle structure  30 . The first handle structure  30  has a handlebar  31 , a male connection block  32 , a supporter  33  and a sleeve ring  34 . The supporter  33  is a hollow pipe having at least one through-slot  331  that can reduce weight and save material. The handlebar  31  has a recess, inside which the supporter  33 , the sleeve ring  34 , and the male connection block  32  are sequentially installed. The supporter  33  is used to enhance the strength of the first handle structure  30 . 
     The second carbon-fiber rod  2  has a rod body  40 , a second joint end and a second balance-weight end. The second balance-weight end has a balance weight  50 , and the second joint end has a second handle structure  60 . The second handle structure  60  has a handlebar  61 , a female connection block  62 , a supporter  63  and a sleeve ring  64 . The supporter  63  is a hollow pipe having at least one through-slot  631  that can reduce weight and save material. The handlebar  61  has a recess  611 , inside which the supporter  63 , the sleeve ring  64 , and the female connection block  62  are sequentially installed. The supporter  63  is used to enhance the strength of the second handle structure  60 . 
     Via the engagement of the male connection block  32  and the female connection block  62 , the first handle structure  30  and the second handle structure  60  form a complete handle, and the first carbon-fiber rod  1  and the second carbon-fiber rod  2  form an easy-to-assemble, easy-to-disassemble, easy-to-carry and easy-to-collect two-section physical-exercise elastic cudgel. The male connection block  32  has an external thread  321 , and the female connection block  62  has an inner thread  621  corresponding to the external thread  321 . The first handle structure  30  and the second handle structure  60  are connected to form a complete handle via the engagement of the external thread  321  and the inner thread  621 . 
     In conclusion, the present invention has a dismountable two-section design, wherein the first handle structure and the second handle structure are used to form a complete handle, whereby the first carbon-fiber rod and the second carbon-fiber rod are joined to form an easy-to-assemble, easy-to-disassemble, easy-to-carry and easy-to-collect two-section physical-exercise elastic cudgel, wherefore is effectively solved the problems caused by too great a length of the conventional physical-exercise elastic cudgel. 
     The embodiments described are only to exemplify the present invention but not to limit the scope of the present invention. Any equivalent modification or variation according to the scope of the present invention is to be also included within the scope of the present invention.
