The transmission module 30 may further include: and a sensing device. The sensing device is disposed in the movable range of the first end of the transmission mechanism 32, and is triggered by the first end of the transmission mechanism 32, for controlling the driving mechanism 31 to stop running.

In some embodiments of the present utility model, the first sensor 34a and the second sensor 34b may be disposed at two ends of the cavity 324 in the length direction, respectively, where the two ends correspond to the start of the movement of the sliding body 322, and the portion between the two ends corresponds to the movement stroke of the sliding body 322.

Illustratively, the first and second sensors 34a, 34b are respectively disposed on the first wall 3241, wherein the first sensor 34a may be disposed at one end of the first wall 3241 and the second sensor 34b may be disposed at the other end of the first wall 3241; the sliding body 322 has two opposite end surfaces, one of which is opposite to the touch end of the first sensor 34a for triggering the first sensor 34a, and the other of which is opposite to the touch end of the second sensor 34b for triggering the second sensor 34b.

The first sensor 34a and/or the second sensor 34b are/is fixed to the chamber housing 324 such that the fixed position thereof is not adjustable, however, the first sensor 34a and/or the second sensor 34b may be movable along the length direction of the chamber housing 324 such that the fixed position thereof is adjustable, thereby adjusting the movable stroke of the first end (or the sliding body 322) of the transmission mechanism 32, and finally adjusting the rotation angle range of the display screen 21.
