[0029] Working principle: During use, firstly, external force pulls the two sets of second support rods 11 and second insertion rods 18 to move in opposite directions. The movement of the second support rods 11 causes the first support rod 8 to move away from the first insertion rod 14. At the same time, the first support rod 8 pulls the first return spring 16 to extend. Then, the two corners of the tablet computer 2 are placed inside the slots 23 located at the top of the second fixing member 4 and the fourth fixing member 6. Then, the force applied to the second support rods 11 and second insertion rods 18 is removed. At this time, the first return spring 16 rebounds and contracts, pulling the first insertion rod 14 to insert into the first insertion slot 9. At the same time, it causes the sleeve 22 to move closer to the tablet computer 2. Then, external force pulls the two sets of first support rods 8 and first insertion rods 14 to move in opposite directions. Moving in the opposite direction, the movement of the first support rod 8 causes the second support rod 11 to move away from the second insertion rod 18 and keep the telescopic fixing device 1 in the horizontal direction. At the same time, the second support rod 11 pulls the second return spring 20 to extend. When the other two corners of the tablet computer 2 fall into the slots 23 located at the top of the first fixing member 3 and the third fixing member 5 respectively, the force applied to the first support rod 8 and the first insertion rod 14 is removed. At this time, the second return spring 20 rebounds and contracts, pulling the second insertion rod 18 to insert into the inside of the second insertion slot 12, while driving the sleeve 22 to move closer to the tablet computer 2, until the four corners of the tablet computer 2 are tightly attached to the inner side of the four slots 23 respectively. At this time, the installation of the telescopic fixing device 1 on the outside of the tablet computer 2 is completed.
