BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a gymnastic apparatus, and more particularly to a gymnastic apparatus wherein the length of the springy belt can be adjusted and clipped stably. [0003] 2. Description of the Prior Art [0004] Nowadays, more and more gymnastic apparatus are manufactured and stretching gymnastic apparatus in particular, the size of such gymnastic apparatus is so small that it is convenient to carry, and has the functions of stretching chest, shoulders, arms and back so as to keep fit. [0005] A conventional stretching gymnastic apparatus as shown in FIGS. 1 and 2, including a main body 1 having a connecting portion 11, a protruding portion 12 and a handle 13, the connecting portion 11 is located between the protruding portions 12, in a suitable position of the protruding portion 12 is mounted the handle 13 for grasping. The connecting portion 11 is solid, the biggest thickness of the connecting portion 11 is thinner than that of the protruding portion 12 and the handle 13, and the connecting portion 11, the protruding portion 12 and the handle 13 are integrally formed and have elasticity. [0006] However, the above-mentioned device still has some disadvantages describes as follows: [0007] Firstly, the length of the connecting portion 11 is unable to adjust, and only can provide single resistance and elasticity, thereby the connecting portion 11 can not be adjusted according to the user's requirement and the using function and scope are restricted. [0008] Secondly, since the connecting portion 11, the protruding portion 12 and the handle 13 are integrally formed and have elasticity, the handle 13 will be distorted when stretching. [0009] Thirdly, the conventional stretching gymnastic apparatus is U-shaped when folded, which is inconvenient to store. [0010] Fourthly, since the connecting portion 11, the protruding portion 12 and the handle 13 are integrally formed, the size of the molds that needed is big and the costs are high. [0011] Fifthly, since the connecting portion 11, the protruding portion 12 and the handle 13 are integrally formed, the conventional stretching gymnastic apparatus cannot be used again even a part is damaged. [0012] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. SUMMARY OF THE INVENTION [0013] The present invention is to provide a gymnastic apparatus comprises two handle assemblies and a flexible strengthening springy belt, wherein the handle assembly including a main body, a cover, a scroll and a shaft, the main body is connected to a positioning seat by a handle, a groove room is mounted in the positioning seat, an opposite through holes and a restricting protruded edge are defined in the front end of the groove room, a wave-shaped clipping member is disposed at a little before the middle section of the groove room, and a containing groove and a engaging groove are disposed at the rear end of the groove room. The cover is mounted on the main body by the shaft, a axis hole and a restricting protruded edge are defined in the front end of the cover, a wave-shaped clipping member is disposed at a little before the middle section of the cover, a containing groove and a hook is disposed at the rear end of the cover, the scroll is positioned between the containing grooves of the main body and the cover for rolling the redundant strengthening springy belt, the ends of the strengthening springy belt are positioned in the handles respectively, and the length of the strengthening springy belt can be adjusted, thereby attain the effect of keeping fit by stretching the strengthening springy belt through the handle assemblies. [0014] The primary objective of the present invention is to provide a gymnastic apparatus, wherein the length of the strengthening springy belt can be adjusted according to the requirement so as to provide suitable resistance and elasticity and expand using scope and function. [0015] The further objective of the present invention is to provide a gymnastic apparatus, wherein since the handle assemblies and the strengthening springy belt are independent members, the handle assemblies are made of materials of high intensity, thereby the handle assemblies will not be deformed when stretching. [0016] The third objective of the present invention is to provide a gymnastic apparatus, wherein the strengthening springy belt can be folded when not using, which is very convenient to store. [0017] The fourth objective of the present invention is to provide a gymnastic apparatus, wherein since the handle assemblies and the strengthening springy belt are independent members, the size of the molds that needed is small and the costs are low. [0018] The fifth objective of the present invention is to provide a gymnastic apparatus, wherein the damaged members can be changed separately which is economical. [0019] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiments in accordance with the present invention. BRIEF DESCRIPTION OF THE DRAWINGS [0020] FIG. 1 is a perspective view of a conventional gymnastic apparatus; [0021] FIG. 2 is a cross sectional view of the conventional gymnastic apparatus; Continue reading about Gymnastic apparatus...
