When the third stoppers 9111 at two ends of the first rod shaft 911 abut against one side of the fixed plate 91 and the movable plate 92, which are away from each other, respectively, a maximum distance is provided between the movable plate 92 and the fixed plate 91, in a process that the adsorption plate 712 drives the display screen of the notebook computer to rotate towards a side away from the base, i.e., in a process of opening the display screen of the notebook computer, the movable plate 92 abuts against the third stopper 9111 close to the display screen of the notebook computer, meanwhile, the third stopper 9111 away from the display screen of the notebook computer abuts against one side of the fixed plate 91 away from the movable plate 92, a maximum distance is maintained between the movable plate 92 and the fixed plate 91, in a process that the adsorption plate 712 drives the display screen of the notebook computer to rotate towards a side close to the base, i.e., in a process of closing the display screen of the notebook computer, the fixed plate 91 is spaced from the third stopper 9111 away from the display screen of the notebook computer and abuts against the movable plate 92, and the movable plate 92 abuts against the third stopper 9111 close to the display screen of the notebook computer, and when the display screen of the notebook computer is closed to the base, the display screen of the notebook computer, the adsorption plate 712 can move away from the notebook computer.
When the adsorption disc 712 fixes a position for adsorbing the display screen of the notebook computer, because the distance between the adsorption disc 712 and the rotating shaft of the notebook computer is different when the display screen of the notebook computer is opened or closed, in this embodiment, a second rod shaft 93 extending along the extending direction of the rocker arm 3 is disposed on one side of the movable plate 92 away from the fixed plate 91, the position adjustment mechanism 9 further includes a movable block 94, the movable block 94 is sleeved on the second rod shaft 93, the adsorption disc 712 is connected to the movable block 94, and the adsorption disc 712 can move in a direction parallel to the second rod shaft 93 relative to the fixed plate 91, so as to avoid damaging the adsorption disc 712.
Further, since a logo of the notebook computer is generally disposed on a side of the display screen of the notebook computer away from the base, and a position of the logo is not suitable for the absorption of the absorption disc 712, in this embodiment, two second shaft shafts 93 are disposed at intervals on a side of the movable plate 92 away from the fixed plate 91, the two second shaft shafts 93 are both sleeved with the movable blocks 94, the position adjustment mechanism 9 further includes a third shaft 95, the third shaft 95 extends along a direction parallel to an axis of the rotation shaft of the notebook computer and penetrates through the two movable blocks 94, both ends of the third shaft 95 are provided with fourth limit parts 951, the fourth limit parts 951 at both ends of the third shaft 95 can respectively abut against a side of the two movable blocks 94, and the absorption disc 712 is sleeved on the third shaft 95 to adjust a position of the absorption disc 712 along a direction parallel to the axis of the rotation shaft, so as to ensure that the absorption disc 712 can stably absorb the side of the display screen of the notebook computer away from the base.
It can be understood that, with the above structure, since the adsorption plate 712 can also move along the direction parallel to the axis of the rotating shaft during the rotation of the display screen of the notebook computer, this embodiment can also avoid the inaccuracy of the test result caused by the carrier 2 shaking along the horizontal direction during the rotation of the display screen of the notebook computer.
Further, if the position of the suction disc 712 is adjusted only by the third lever shaft 95 in the direction parallel to the axis of the rotation shaft, the adjustment distance of the suction disc 712 may be limited due to the limited length of the third lever shaft 95, and for this reason, in the present embodiment, the fixing plate 91 is slidably connected to the tie bar 8, the suction position of the suction disc 712 is adjusted by adjusting the position of the fixing plate 91, and the fixing plate 91 is fixed to the tie bar 8 after the fixing plate 91 is adjusted to the position suitable for suction in the extending direction of the tie bar 8.
It can be understood that, in this embodiment, before testing the pivot of notebook computer, need detect the force sensor who sets up in microscope carrier 2 below, before testing the pivot of notebook computer, place the weight on microscope carrier 2, detect whether can normally work through the weight force sensor.
As shown in fig. 1, in this embodiment, a monitoring mechanism 11 is further installed on one side of the rack 1, the detecting mechanism includes a computer 111, the computer 111 is in communication connection with the force sensor, and an operator can monitor the detection data of the force sensor through the computer 111 in real time.
