BACKGROUND 
     1. Technical Field 
     The present disclosure relates to bearing devices and, particularly, to a bearing device used in surface treatment techniques. 
     2. Description of Related Art 
     With the development of technology, appearance of portable electronic devices e.g., mobile phones and notebooks has been greatly improved. Painting is an effective method to improve the appearance. 
     Usually, a plurality of portable electronic devices are fixed on a bearing device firstly, and then painted completely using sprays. A typical bearing device includes a plurality of bearing members. Each bearing member is used to bear a plurality of portable electronic devices. The bearing members are connected to each other. A distance between adjacent bearing members is slightly bigger than a size of one portable electronic device, thus avoiding interference between the portable electronic device and adjacent bearing members. 
     However, the distance between adjacent bearing members cannot be adjusted according to the size of the portable electronic device, thus limiting the amount of portable electronic devices to be fixed thereon, and influencing painting efficiency. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     The present bearing device is suitable for fixing a workpiece, e.g., mobile phone and notebook thereon in painting. 
       FIG. 1  shows an exemplary bearing device  10 . The bearing device  10  includes a plurality of bearing members  11  and connecting members  12 . The connecting members  12  are used to connect the bearing members  11  together. 
     Referring to  FIG. 3 , each bearing member  11  includes a pole  111  and a plurality of bearing flakes  112 . The bearing flakes  112  equally and spacedly protrude from a peripheral wall of the pole  111 . In this embodiment, the bearing flake  112  is “L”-shaped, used to bear one portable electronic device thereon. The pole  111  includes a first connecting end  113  and a second connecting end  114  opposite to the first connecting end  113 . The first connecting end  113  is a pole, the second connecting end  114  is a hollow pole. The diameter of the second connecting end  14  is larger than that of the first connecting end  13 . The first connecting end  113  and the second connecting end  114  connect each other, thus forming a resisting wall  115 . The resisting wall  115  faces the first connecting end  113 . The resisting wall  115  includes two latching blocks  1151  symmetrically protruding therefrom. In this embodiment, the latching block  1151  is a rod. The second connecting end  114  defines a first latching slot  1141  with an interior peripheral wall  1142 . The interior peripheral wall  1142  includes four clamping blocks  1143 , forming a second latching slot  1144  between every two adjacent clamping blocks  1143 . In this embodiment, the pole  111  are becoming smaller and smaller in diameter from the second connecting end  114  to the first connecting end  113 , thus making the bearing members  11  connect each other in phase. 
     The connecting members  12  is generally a pole, and includes a male connecting end  121  and a female connecting end  122 . A diameter of the male connecting end  121  is smaller than the diameter of the female connecting end  122 , forming a ladder wall  123  therebetween. The male connecting end  121  includes two male connecting blocks  1211  symmetrically protruding therefrom. In this embodiment, the male connecting block  1211  is a rod. The female connecting end  122  is a hollow body, and defines a female connecting groove  1221  with an interior peripheral wall  1222 . The interior peripheral wall  1222  includes two protrusions  1223  symmetrically protruding therefrom, forming two clamping slots  1224  therebetween. The connecting members  12  can be provided in different lengths. Therefore, when using connecting members  12  with different lengths to connect two bearing members  11 , a distance between these two bearing members  11  can be changed. 
     Referring to  FIG. 2 , to connect these bearing members  11 , the first connecting end  113  of a bearing member  11  is connected to the second connecting end  114  of another bearing member  11 , such that two latching blocks  1151  latch into two of the four second latching slots  1144 . In this way, the bearing members  11  can be connected together in sequence. 
     To adjust the distance between adjacent bearing members  11 , the connecting members  12  can be placed between every two bearing members  11 . For example, A male connecting end  121  of a connecting member  12  is inserted into a second connecting end  114  of a bearing member  11 , until the two male connecting blocks  1211  of the male connecting end  121  are latched into two of the four second latching slots  1144  of the second connecting end  114 . Then the female connecting end  122  of the same connecting member  12  is connected to a first connecting end  113  of another bearing member  11 , until the latching blocks  1151  of the first connecting end  113  are latched into two clamping slots  1224  of the female connecting end  122 . At this time, the ladder wall  123  resists the second connecting end  114 , and the resisting wall  115  resists the female connecting end  122 . 
     It is to be understood, the number of male connecting blocks  1211  of each connecting member  12  can be four. The number of the latching blocks  1151  can also be four. 
     The bearing device  10  can adjust the distance between adjacent bearing members  11  by changing one connecting member  12  for another one with a different length, thus bearing the most portable electronic devices at one time of painting, and improving painting efficiency. 
     It is to be understood, however, that even through numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of sections within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms, in which the appended claims are expressed.
