     DETAILED DESCRIPTION OF THE INVENTION 
       [0047]    The following descriptions for the respective embodiments are specific embodiments capable of being implemented for illustrations of the present invention with referring to appended figures. 
         [0048]    Please refer to  FIG. 2  and  FIG. 3 .  FIG. 2  shows an inspection device for a glass substrate according to a preferable embodiment of the present invention. The inspection device for the glass substrate comprises a holder  21 , a plurality of probes  22 , a plurality of stretch controller  23  (in  FIG. 3 ), a top cover  24  and a plurality of wires. Each of the stretch controllers  23  corresponds to one probe  22 . The stretch controller  23  control the probe  22  to move along the predetermined direction B 1  to stretch the probe  22  out of the holder  21 . The stretch controller  23  also can control the probe  22  to move along the reverse direction of B 1  to retract the probe  22  backward in the holder  21 . The direction B 1  is the direction that the probe  22  is inserted into the glass substrate (not shown) for inspection. 
         [0049]    Please refer to  FIG. 3 , which shows a structure diagram of the stretch controller  23  in  FIG. 2 . The stretch controller  23  comprises a movable control base  231 , a stretch control component  233  and a retract control component  232 . The movable control base  231  is fixedly connected with the probe  22 . 
         [0050]    Please refer to  FIG. 3 . The stretch control component  233  comprises a first electromagnetic component  234  and a second electromagnetic component  235 . The first electromagnetic component  234  is positioned on the movable control base  231  and the second electromagnetic component is positioned on the holder  21 . In an exemplary embodiment, the stretch control component  233  can be other structures as long as the structure is capable of moving the probe  22  with a predetermined distance D along the direction B 1 . As the probes  22  are moved with the predetermined distance D along the direction B 1 , the probes  22  are inserted into the glass substrate. 
         [0051]    In the embodiment shown in  FIG. 2 , the retract control component  232  is an elastic element and preferable a spring structure. Other structure also can be considered as long as the structure can move the probe  22  with the predetermined distance D along the reverse direction B 2  of the direction B 1 . 
         [0052]    The top cover  24  is employed for holding the wires  25 . A control circuit (not shown) inputs or not inputs of an electrical signal to the wires  25 . The wires  25  are electrically connected to the first electromagnetic components  234 . After the control circuit inputs the electrical signal, attractive force between the first electromagnetic component  234  and the second electromagnetic component  235  is larger than a maximum spring force of the retract control component  232 . Therefore, the stretch control component  233  is capable of moving the probe  22  with the predetermined distance D along the direction B 1 . 
         [0053]    Alternatively, the top cover  24  has a print circuit board. The print circuit board comprises the control circuit (not shown). The control circuit is electrically connected to the wires  25  and input or not input the electrical signal to the wires  25  for controlling the first electromagnetic component  234  and the second electromagnetic component  235 . 
         [0054]    The working principle of the preferable embodiment shown in  FIG. 2  is introduced hereafter: 
         [0000]    Please refer to  FIG. 3  and  FIG. 4 . As the inspection for the glass substrate is proceeding, the number of the pads on the glass substrate is seven, hypothetically. The number of the probes  22  of the inspection device for the glass substrate according to the present invention is fourteen. According to the positions of the pads, the control unit controls the wires  25  corresponding to the seven probes  22  at the right side shown in  FIG. 4  to be electrified (also referring to  FIG. 2 ). After the wires  25  are electrified, the first electromagnetic component  234  receives the electrical signal and attracts the second electromagnetic component  235 . Because, the attractive force between the first electromagnetic component  234  and the second electromagnetic component  235  is larger than a maximum spring force of the retract control component  232 . Therefore, the movable control base  231  is moved with the predetermined distance D along the predetermined direction B 1  to stretch the probe  22  fixed on the movable control base  231  out of the holder  21  with the predetermined distance D along the predetermined direction B 1 . The probe  22  is inserted into the glass substrate for inspection. 
         [0055]    Meanwhile, the control unit controls the wires  25  corresponding to the seven probes  22  at the left side shown in  FIG. 4  to be not electrified (also referring to  FIG. 2 ). The first electromagnetic components  234  corresponding to the probes  22  (No. 1-No.7) do not receive the electrical signal and will not attract the second electromagnetic components  235 . The retract control component  232  controls the movable control base  231  to move with the predetermined distance D along the reverse direction B 2  of the direction B 1  to retract the probe  22  backward in the holder  21 . 
         [0056]    According to the present invention, the process station has no need to be down for setting up the probes  22  but the probes  22  corresponding to the number of the pads on the glass substrate for inspection can be flexibly stretched or retracted and tremendously promote the inspection efficiency. 
         [0057]    As is understood by a person skilled in the art, the foregoing preferred embodiments of the present invention are illustrative rather than limiting of the present invention. It is intended that they cover various modifications and similar arrangements be included within the spirit and scope of the appended claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structure.
