BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The disclosure relates to an electronic device with a movable display. 
         [0003]    2. Description of Related Art 
         [0004]    Usually, displays of electronic devices are movable for convenient operation and to save space. For example, a clamshell mobile phone generally has a main body and a display slidably mounted to the main body. The displays are pushed relative to the main body by fingers of the operator abutting against the displays. However, the displays are easily abraded, which is unsightly.

In the embodiment, the first resilient member  6352  is a coil spring. 
         [0022]      FIG. 3  shows the operation apparatus  80  includes an operation member  82 , two second resilient members  84 , and an adjusting member  86 . 
         [0023]    The operation member  82  includes a rectangular sliding plate  821 , the sliding plate  821  includes an inner side surface  820 . A connecting shaft  822  perpendicularly protrudes out from a middle of an upper side of the inner side surface  820 . Two opposite tabs  823  protrude out from the inner side surface  820 , and are located at two opposite sides of the connecting shaft  822 . Two pieces  825  protrude out from a middle of the inner side surface  820 , and adjacent to the tabs  823 . Two guiding poles  826  extend from the pieces  825  away from each other. Each guiding pole  826  is spaced and parallel to the sliding plate  821 . A plurality of skid-proof bars  827  protrudes out from an outer side surface of the sliding plate  821  opposite to the inner side surface  820  (shown in  FIG. 4 ). 
         [0024]    In the embodiment, each second resilient member  84  is a coil spring. 
         [0025]    The adjusting member  86  is substantially triangular and includes a substantially C-shaped rotation portion  862 , two connecting pieces  864  slantingly extending down from two opposite distal ends of the rotation portion  862  and away from each other, and two hooks  865  formed on distal ends of the connecting pieces  864 . The hooks  865  extend toward each other. 
         [0026]      FIGS. 4 and 5  show that in assembly of the electronic device  100 , the shaft  6316  of the bracket  631  is inserted in the shaft hole  6332  of the gear  633  from a side surface of the gear  633  opposite to the protrusion  6331 . The gear  633  is received in the recess  6313 , and a portion of gear  633  is exposed out of the top surface  6311  of the bracket  631 . The first resilient members  6352  fit about the connecting poles  6356  of the connecting members  6354 , distal ends of the connecting poles  6356  are inserted into the through holes  6358  of the rotating poles  6351 . The pivots  6355  of the connecting members  6354  are pivotably inserted into the connecting holes  6335  of the gear  633 . 
         [0027]    The rotating poles  6351  are pivotably inserted into the rotation holes  6315  of the bracket  631 . Thus, each first resilient member  6352  is sandwiched between the shrink-ring  6357  and the corresponding rotating pole  6351 . 
         [0028]    In assembly of the operation apparatus  80 , the second resilient members  84  are fitted about the guiding poles  826  of the operation member  82 . The rotation portion  862  of the adjusting member  86  is fitted about the connecting shaft  822  of the operation member  82 . 
         [0029]    The transmission mechanism  63  is received in the receiving space  422  of the base  40 , the pole  6336  is received in the guiding slot  424  of the base  40 , and the portion of gear  633  is exposed out of the top surface of the base  40 . The operation apparatus  80  is received in the guiding slot  424  of the base  40 , and distal ends of the guiding poles  826  are inserted into the guiding holes  426  of the base  40 . The second resilient members  84  are sandwiched between the pieces  825  and the base  40 . The pole  6336  of the gear  633  is located between the hooks  865  of the adjusting member  86 . The display  20  is covered on the base  40 , to allow the rack  61  to engage with the gear  633 . The positioning bar  26  is stopped between the stopping bars  427  of the base  40 . 
         [0030]      FIGS. 6-8  show that in use, the skid-proof bars  827  of the operation member  82  is pushed forward, to slide the sliding plate  821  forward along the guiding slot  424 . The guiding poles  826  slide forward along the guiding holes  426 . The second resilient member  6352  positioned at the front of the operation member  82  is pressed, to be deformed. The pole  6336  is latched in the hook  865  and positioned at a rear of the adjusting member  86 . The pole  6336  is rotated up about the shaft  6316 , to pivot the gear  633  clockwise. The gear  633  drives the rack  24  to move forward, to slide the display  20  forward relative to the base  40 . The pivots  6355  pivot in the connecting holes  6335  of the gear  633 , the rotating poles  6351  pivot in the rotation holes  6315  of the bracket  631 , and the connecting poles  6356  pivot in the through holes  6358  of the rotating poles  6351 . The rotating poles  6351  and the corresponding shrink-rings  6357  press first resilient members  6352  until the connecting poles  6356  are rotated to be in the same horizontal line. The operation member  82  is further pushed forward, to allow the connecting poles  6356  to misalign, and the adjusting member  86  is blocked by the corresponding tab  823 . The first resilient members  6352  are restored to bias the connecting members  6354  to slide away from the corresponding rotating poles  6351 . The connecting members  6354  drive the gear  633  to pivot clockwise. The gear  633  further drives the rack  24  to move forward, until the positioning bar  26  of the display  20  is blocked by the stopping bar  427  positioned on the front of the base  40 . The operation member  82  is released, the second resilient member  84  positioned at the front of the operation member  82  is restored to bias the sliding plate  821  back, and the adjusting member  86  is pivoted back. The pole  6336  of the gear  633  is received in the hook  865  positioned at a front of the adjusting member  86 . 
         [0031]    When the display  20  needs to be closed, the skid-proof bars  827  are pulled rearward, to slide the sliding plate  821  rearward along the guiding slot  424 . The guiding poles  826  slide rearward along the guiding holes  426 . The second resilient member  6352  positioned at the rear of the operation member  82  is pressed, to be deformed. The pole  6336  is rotated up about the shaft  6316 , to pivot the gear  633  anticlockwise. The gear  633  drives the rack  24  to move rearward. The display  20  is slid rearward relative to the base  40 . The pivots  6355  pivot in the connecting holes  6335  of the gear  633 , the rotating poles  6351  pivot in the rotation holes  6315  of the bracket  631 , and the connecting poles  6356  pivot in the through holes  6358  of the rotating poles  6351 . The rotating poles  6351  and the corresponding shrink-rings  6357  press the first resilient members  6352 , until the connecting poles  6356  are rotated to be in the same horizontal line. The operation member  82  is further pulled rearward, to allow the connecting poles  6356  to misalign, and the adjusting member  86  is blocked by the corresponding tab  823 . 
         [0032]    The first resilient members  6352  are restored to bias the connecting members  6354  to slide away from the corresponding rotating poles  6351 , to drive the gear  633  to pivot anticlockwise. The gear  633  further drives the rack  24  to move rearward, until the positioning bar  26  is blocked by the stopping bar  427  positioned on the rear of the base  40 . The operation member  82  is released, the second resilient member  84  positioned at the rear of the operation member  82  is restored to bias the sliding plate  821  back, and the adjusting member  86  is pivoted back. The display  20  is fully closed on the base  40 .
