[0050] Furthermore, the first rod 10 is provided with a positioning boss 11 and a connecting boss 12, the connecting boss 12 is connected to the disc 21, and the adjusting boss 212 and the resetting boss 215 clamp the positioning boss 11 so as to fix the disc 21 on the first rod 10. Specifically, the first rod 10 is in an elongated shape, and one end of the first rod 10 is provided with a positioning boss 11 and a connecting boss 12 protruding toward the second rod 30, the disc 21 is sleeved on the connecting boss 12, and the positioning boss 11 is respectively in contact with the circumferential surface 216 of the disc 21, the resetting boss 215 and the adjusting boss 212.

[0051] Furthermore, the second rod 30 includes a fixed plate 31, a positioning pin 32, a rotating pin 33 and a closing cover 34, the ejector 22 is slidably connected to one end of the positioning pin 32, the other end of the positioning pin 32 is connected to the fixed plate 31, and a return spring 321 is sleeved on the positioning pin 32, the two ends of the return spring 321 respectively abut against the ejector 22 and the fixed plate 31, the connecting boss 12 is provided with an axial hole, the rotating pin 33 passes through the axial hole and is rotatably connected to the connecting boss 12, one end of the rotating pin 33 is connected to the fixed plate 31, and the other end is connected to the closing cover 34.

[0052] Furthermore, the rotating pin 33, the disk 21 and the connecting boss 12 are coaxially arranged. Specifically, a through hole is provided on the circular surface 217 of the disk 21, and the connecting boss 10 is connected to the disk 21 through the through hole. The middle of the end surface of the connecting boss 10 facing the second rod 30 is provided with a through shaft hole, and the rotating pin 33 is rotatably connected to the connecting boss 12 through the shaft hole. When the second rod is fixed, under the action of external force, when the first rod 10 rotates relative to the second rod 30, the disk 21 rotates relative to the ejector pin 22 around the rotating pin 33, thereby adjusting the angle between the first rod 10 and the second rod 30.

[0053] The working principle of the present invention is:

[0054] When the second rod 30 is fixed, the first rod 10 rotates relative to the second rod 30 under the action of an external force, and the disk 21 and the ejector pin 22 move relative to each other.

[0055] Please see Figure 5 When adjusting the angle, the ejector 22 moves clockwise along the adjusting surface 2162 from the starting point, and the starting point is located on the adjusting surface 2162 close to the reset inclined surface 2151. First, the ejector 22 slides over the moving inclined surface 2112 of the first adjusting slot 211 and moves into the stop surface 2111 of the first adjusting slot 211. The stop surface 2111 prevents the ejector 22 from moving counterclockwise. The ejector 22 holds the stop surface 2111, thereby maintaining the first rod 10 and the second rod 30 at the current supporting angle. Then, the ejector 22 continues to move along the adjusting surface 2162. The adjusting surface 2162 slides clockwise to change the current supporting angle. At this time, the ejector pin 22 leaves the stop surface 2111 of the first adjusting slot 211 and moves on the moving inclined surface 2112 of the next adjacent adjusting slot 211 until the ejector pin 22 slides into the stop surface 2111 of the next adjusting slot 211. Each time the ejector pin 22 slides into a stop surface 2111, one angle is adjusted until the ejector pin 22 slides over the stop surface 2111 of the last adjusting slot 211 and moves to the adjusting inclined surface 2121.

[0056] When resetting, the ejector 22 continues to move clockwise along the adjustment surface 2162 until the adjustment slope 2121 squeezes the ejector 22, so that the ejector 22 moves in the circumferential direction and squeezes the reset spring 321 along the positioning pin shaft 32 to move axially to the reset surface 2163. The end surface of the positioning boss 11 close to the adjustment boss 212 blocks the clockwise circumferential movement of the ejector 22. At this time, the ejector 22 moves counterclockwise along the reset surface 2163 to the reset groove 214. The ejector 22 slides through the reset groove 214 and moves to the reset slope 2151. Since the reset slope 2151 squeezes the ejector 22, the ejector 22 moves in the circumferential direction and is pushed by the reset spring 321 to move axially along the positioning pin shaft 32 back to the starting point. The ejector 22 moves relative to the disk 21. Starting from the starting point, the ejector 22 adjusts the angle in the clockwise direction and resets in the counterclockwise direction. It should be understood that in other embodiments, the ejector pin 22 can move counterclockwise to adjust the angle and reset in clockwise direction when starting from the starting point.

One end of the first arm 40 is fixedly connected to the first rod 10, and the other end is connected to the first plate 60. One end of the second arm 50 is fixedly connected to the second rod 30, and the other end is connected to the second plate 70.

[0059] Furthermore, the electronic device support also includes a third arm 80 and a fourth arm 90, the third arm 80 and the fourth arm 90 are rotatably connected, the first arm 40 and the third arm 80 are respectively connected to the two ends of the first plate 60, and the second arm 50 and the fourth arm 80 are respectively connected to the two ends of the second plate 70, so as to improve the stability of the electronic device support.
