In addition to the adjustment of the elevation angle of the conventional display, a lifting device is usually added to adjust the height or further to enable the display screen to rotate left and right, so that the functions of the conventional display become more complete and diversified, and the requirements of different users are met. The screens of the above mentioned types are mostly horizontally disposed, and when viewing straight documents, pictures or pictures, the picture will be reduced and inconvenient. Therefore, in order to view the image conveniently, the screen must rotate the horizontal state into the vertical state through the rotation function of the supporting frame to display the complete image,

wherein, as shown in the patent of 'support frame capable of interlocking screen rotation and height adjustment' of the invention No. TWI 386054 in Taiwan, it mainly comprises a guide slot is arranged on a support frame, the lower end of the guide slot is connected with an enlarged hole; a sliding part movably combined on the bracket, and combined with a screen by a first pivot, wherein the tail end of the first pivot is provided with a locking part which is combined with the expanding hole and is provided with a wide edge and a narrow edge; when the screen is at the lowest position and is in a horizontal state, the locking part of the first pivot is located in the enlarged hole, the narrow side of the locking part is aligned with the guide slot, the locking part can move up and down in the guide slot to adjust the height of the screen, and the screen cannot be rotated vertically when the height of the screen is raised; when the screen is rotated to be vertical at the lowest position, the wide side of the first pivot locking part is stopped at the lower end of the guide slot, so that the screen cannot be raised; therefore, the screen in the vertical state can only be kept at the lowest position to maintain the stability of the whole and avoid falling. As shown in the patent documents TW I340595, "plane rotation mechanism of supporting device", TW I352787, "rotation structure of supporting frame", and TW 201941591a, "electronic device and supporting frame thereof", the screen can be rotated by the mutual linkage of the mechanisms.

With the structure disclosed in the above patent, the screen can be rotated from horizontal to vertical to display a complete picture. However, in practical use, each patent only uses the linked mechanism, and the screen can be rotated only when the user continuously applies force, but does not consider the requirement of "labor saving" and "stable rotation" in the whole rotation process, so that the screen still consumes quite force at the end of rotation, and the phenomenon of collision is easily generated due to too fast rotation. In view of the above, in order to provide a structure different from the prior art and improve the above disadvantages, the inventor has experienced many years and has continuously researched and developed the invention.
