Abstract
The utility model discloses a fixing base of a liquid crystal display with adjustable torsion. The fixing base comprises a connecting frame which is provided with the panel of the display and a supporting frame which is pivotally connected with the connecting frame. A torsion spring driving and reversing mechanism is arranged on a pivot device which is connected between the connecting frame and the supporting frame. The torsion spring device of the utility model is provided with the torsion spring driving and reversing mechanism. The torsion spring device can provide proper torsion when relatively rotating and positioning in a certain range between the connecting frame and the supporting frame which are pivotally connected through the pivot device. The pivot device can not be un-positioned due to the inadequate radial frictional force of the pivot device. In addition, a small angle can not only be provided between the connecting frame and the supporting frame due to the addition of the torsion spring.
