[0036] At least two third friction plates 2-16 are provided.

[0037] This utility model's mechanism is assembled on the upper arm assembly 3. Through the rotation mechanism on the ball joint assembly 2, the computer display screen 4 can be tilted forward and backward to meet the user's different viewing angles. The ball joint assembly 2 has a large load-bearing capacity, and the computer display screen 4, weighing within the range of 16-20KG, can be positioned freely without sagging.

[0038] The ball head assembly 2 is equipped with a two-stage gear transmission assembly. The first gear 2-5 is fixed to the first gear shaft 2-6 by the first pin 2-4; the second gear 2-11 is fixed to the second gear shaft 2-12 by the second pin 2-10.

[0042] The angle adjustment process of ball head assembly 2:

[0043] 1. When it is necessary to adjust the front and rear angle of the computer screen 4, the ball joint connector 2-2 swings up and down, driving the second gear 2-11 and the first gear 2-5 to rotate in opposite directions, causing the two friction plates of the two pairs of first friction plates 2-7 at both ends of the first gear shaft 2-6 to rotate relative to each other (the friction plate that is close to the ball joint seat 2-1 does not move), thereby generating frictional resistance;

[0044] 2. Two friction plates in the two pairs of second friction plates 2-13 at both ends of the second gear shaft 2-12 rotate relative to each other (the friction plate that is in close contact with the ball head seat 2-1 remains stationary), thereby generating frictional resistance;

[0045] 3. Depending on the weight of the computer screen 4, the tightening torque of the first screw 2-9 and the second screw 2-15 can be adjusted to increase or decrease frictional resistance.
