A force spring 323 provides the force required by the display.

When the force-increasing mode is turned off, please refer to Figures 5 to 6, and only need to operate the toggle portion 432 of the switching member 43 to toggle down, so that the second positioning portion 431 is separated from the first positioning portion 414 to remove the fixing At this time, the elastic member 42 is elastically reset between the pivoting portion 411 and the side portion of the cover plate 11, so that the abutting portion 412 of the linking member 41 is separated from the first constant force spring seat 31 to remove the abutment and fixation; And the second positioning portion 431 moves downward along the inclined guide portion 413 . The first abutting portion 312 of the first constant force spring seat 31 and the second abutting portion 321 of the second constant force spring seat 32 are in contact with each other. 2 When applying downward force, the first and second constant force spring seats 31 , 32 move synchronously with the lifting device 2 , and no force is generated. At this time, the force required by the lifting device 2 to exert downward force is generated by the constant force spring originally installed at the lower end of the lifting device 2 .

In short, in this embodiment, the lifting device 2 is slidably disposed on the supporting device 1 , the linking member 41 is actuated correspondingly by the switching of the stroke of the switching member 43 , and the elastic member 42 is used to elastically control the reciprocating action of the linking member 41 . Force, the switching member 43 is used to switch the operation mode of the control link member 41. By changing the corresponding connection relationship between the force value generating module 3 and the switching device 4, the switching member 43 of the switching device 4 can be switched on or off.
