The position of the fixing part 152 is fixed and sleeved on the rotating rod 151, and preferably, but not limited to, the fixing part 152 is sleeved on the rotating rod 151 in a threaded connection manner; the rotating rod 151 is fixed to the first base 11 (or the second base 12), and the rotating rod 151 rotates around its central axis to convert the rotating motion into a linear motion of the rotating rod 151 relative to the fixing portion 152, so as to indirectly drive the first base 11 (or the second base 12) to perform the linear motion.
The rotating rod 151 is further marked with a scale value for obtaining the distance for driving the first base station or the second base station to move by reading the scale value, so that the distance for the relative movement of the first base station 11 and the second base station 12 can be quickly, accurately and clearly obtained, and the first base station 11 and the second base station 12 can be moved accurately.
Preferably, the first base 11 and/or the second base 12 are provided with a heating module 13, and the heating module 13 is used for heating the display panel located between the first base 11 and the second base 12.
