The sum of the thickness of the connecting cylinder 32 and the thickness of the first rotating handle 52 is consistent with the thickness of the second main body portion 42, with a reasonable layout and a simple structure.

[0034] Furthermore, the second adjusting and locking member 60 can control the fixed or rotational connection between the second main body portion 42 and the electronic device support rod 20; in one embodiment, as Figure 3 shown, on both sides of one end of the electronic device support rod 20 close to the second main body portion 42, there are respectively provided connecting ears 21 extending outward; on the second main body portion 42, there is provided a connecting portion 421; a channel 422 runs through the middle of the connecting portion 421 along its length direction; between the two connecting ears 21, there is provided a receiving cavity 22 for receiving the connecting portion 421; on the two connecting ears, there are correspondingly provided second through holes 211 communicating with the receiving cavity 22; the two connecting ears 21 are rotationally or fixedly connected to the connecting portion 421 through the second adjusting and locking member 60; in another embodiment, similarly, the connecting ears can also be provided on the second main body portion, and the connecting portion is provided at one end of the electronic device support rod.

The support plates 423 not only increase the distance between the electronic device support rod and the connecting cylinder, enabling a larger movement range of the electronic device support rod, but also prevent interference with the first adjustment locking member during the rotation of the electronic device support rod on the connecting portion 421; the user experience is better.

[0036] Furthermore, based on a locking and adjustment principle similar to that of the first adjustment locking member 50, a plurality of second convex teeth 425 circumferentially distributed with the axis of the channel 422 as the center are provided on the end surface of any end of the connecting portion 421 facing the connecting ear 21; the outer contour of the connecting portion 421 is a cylindrical structure; a plurality of second tooth grooves 212 adapted to any plurality of second convex teeth 425 are provided on the surface of the connecting ear 21. This increases the frictional force between the connecting ear and the connecting portion, enabling stable positioning after the two are rotated to a suitable angle.

[0037] Furthermore, the second adjustment locking member 60 includes a second rotating handle 61 movably disposed outside one of the connecting ears 21, a locking nut 62 fixedly connected to the other connecting ear 21, and a second adjustment screw 63 fixedly connected to the second rotating handle 61; the axis of the locking nut 62 and the axis of the second adjustment screw 63 are on the same straight line; when the second main body portion 42 and the electronic device support rod 20 are installed in place, the second adjustment screw 63 passes through one connecting ear 21 and the channel 422 and is threadedly connected to the locking nut 62 on the other connecting ear 21; during use, the user only needs to rotate and tighten the second adjustment screw and the locking nut on the connecting ear, causing the two connecting ears to bend and deform towards the accommodating cavity 22, and clamping the connecting portion tightly to directly fix the electronic device support rod 20 to the rotating member. Conversely, only by rotating the second adjustment screw reversely to contact the tightened state of the locking nut can the electronic device support rod be moved, and the adjustment is flexible.

[0038] Further, the electronic device support rod 20 includes a first rod 23 connected to the second main body 42, a second rod 24 movably connected to the first rod 23, and a third adjustment and locking member 25 connecting the first rod 23 and the second rod 24; a receiving portion 231 for receiving the second rod 24 is provided on the first rod 23; a universal joint ball 26 or a clamping assembly (not shown in the figure) connected to the electronic device protective case is provided at the free end of the second rod 24; in the present utility model, the electronic device includes but is not limited to a mobile phone, an iPad, a tablet computer, a reader, etc.; the third adjustment and locking member may adopt the same structure as the second adjustment and locking assembly in the prior application, and its locking and adjusting principle is also the same as the locking principle of the prior application, which will not be elaborated here; the third adjustment and locking member has a locking state and an unlocking state; when the third adjustment and locking member is in the locking state, the first rod and the second rod are fixedly connected; when the third adjustment and locking member 25 is in the unlocking state, the second rod 24 can slide relative to the first rod 23; as Figures 1-2 shown, the receiving portion 231 is located inside the first rod 23; the first rod 23 and the second rod 24 are slidably telescopically connected, and the length can be adjusted, which is convenient for the user to adjust the length of the electronic device support rod 30 according to the actual use situation, and the user experience is more convenient. It should be noted that, in another embodiment, when the third adjustment and locking member 25 is in the unlocking state, the second rod 24 rotates relative to the first rod 23 with the axis of the third adjustment and locking member 25 as the rotation center, as Figure 5 shown, the receiving portion 231 is located on one side surface of the first rod 23; the user can rotate and fold the second bracket 24 into the receiving portion for storage according to the use requirements, or rotate the second bracket 24 outwards to expand the overall length of the electronic device support rod for easy use. Optionally, the electronic device support rod can also be composed of a fixed rod structure in the prior art; the above are all within the protection scope of the present utility model.
