Alternatively, the fixing lugs may be provided as two mutually parallel, or nearly parallel plate-like convex structures formed extending in the axial direction of the base body 113. Correspondingly, the turning lugs are provided as one plate-like projection extending in the axial direction of the adjustment member 12, and the distance between the two plate-like projections on the base 11 coincides with the thickness of the one plate-like projection on the adjustment member 12. It should be noted that the embodiment of the present utility model is not limited to the number of plate-like projections as the rotation lugs and the fixing lugs.

In order to make the connection of the adjustment member 12 and the base 11 more stable, in a further possible implementation, a fastener 13 may be provided between the adjustment member 12 and the base 11. For example, a first fixing hole 1111 may be provided on a fixing lug as the fixing portion 111, an axial direction of the first fixing hole 1111 is perpendicular to an axial direction of the base body 113, and the first fixing hole 1111 and the fastener 13 are adapted; a second fixing hole 1221 corresponding to the first fixing hole 1111 is provided on the rotation lug as the connection part 122, and the second fixing hole 1221 is adapted to the fastener 13.

For example, the first fixing hole 1111 may be provided as a through hole, the second fixing hole 1221 on one plate-like protrusion of the rotation lug may be provided as a through hole, the second fixing hole 1221 on the other plate-like protrusion of the rotation lug may be provided as a screw hole, and the fastener 13 may employ a bolt adapted to the screw hole. After the rotation lug is aligned with the fixing lug, the fastener 13 is passed through the second fixing hole 1221 and the first fixing hole 1111, and the fastener 13 is screwed on the rotation lug by a screw structure. Alternatively, the first fixing hole 1111 and the second fixing hole 1221 are each provided as a through hole, and the fastener 13 may employ a bolt pair, and the rotating lug and the fixing lug may be connected using the bolt pair.

As yet another example, a circular groove may be provided on the fixing lug as the fixing portion 111, the axial direction of the circular groove being perpendicular to the axial direction of the base body 113, a cylindrical protrusion corresponding to the circular groove may be provided on the rotating lug as the connecting portion 122, and an interference fit may be formed between the rotating lug and the fixing lug, with a large rotating friction force therebetween. After the rotating lug is connected with the fixing lug, the cylindrical protrusion is located in the circular groove, and when the adjusting piece 12 is rotated and adjusted, the adjusting piece 12 can be rotated by taking the cylindrical protrusion as a rotating shaft.

In this embodiment, since the fixing lugs are provided on the base 11 and the rotating lugs are provided on the regulating member 12, the regulating member 12 and the base 11 can be rotatably connected with the fixing lugs by the rotating lugs; further, the first fixing hole 1111 is provided in the fixing lug, the second fixing hole 1221 is provided in the rotating lug, and the fastening member 13 may be used, and the fastening member 13 may be inserted into the first fixing hole 1111 and the second fixing hole 1221, so that the fastening member 13 may be used as a rotation shaft when the adjusting member 12 rotates relative to the base 11, and the pressing force between the rotating lug and the fixing lug may be adjusted by the fastening member 13, so that the friction force between the rotating lug and the fixing lug may be adjusted. When the angle of the adjusting member 12 relative to the base 11 needs to be adjusted, the fastener 13 can be loosened first, so that the adjusting member 12 can be adjusted, and when the adjusting member 12 is adjusted to a required angle, the fastener 13 is tightened again, so that enough friction force exists between the rotating lug and the fixing lug, and therefore the adjusting member 12 cannot rotate relative to the base 11 at will.

In yet another possible implementation, as shown in fig. 3, a stopper 14 may be provided at an end of the adjustment member 12 remote from the base 11, and when the stand 1 is mounted on the electronic device, a movement range of the adjustment member 12 with respect to the electronic device in the axial direction may be limited by the stopper 14. For example, the stopper 14 may be provided as a circular ring having a diameter larger than that of the first regulating portion 121, and the circular ring may be fixed to the end of the regulating member 12 remote from the base 11. The stopper 14 may be provided as a cylinder having a diameter larger than that of the first regulating portion 121, and the cylinder may be fixed to the regulating member 12 at an end remote from the base 11. The stopper 14 may be manufactured separately from the adjusting member 12, and the separately manufactured stopper 14 may be fixed to the adjusting member 12, or the stopper 14 and the adjusting member 12 may be integrally formed, which is not limited in the embodiment of the present utility model.

In this embodiment, since the stopper 14 is provided at the end of the adjusting member 12 away from the base 11, the stopper 14 can prevent the adjusting member 12 from being pulled out of the electronic device when the position of the bracket 1 relative to the electronic device is adjusted by the first adjusting portion 121 on the adjusting member 12 after the bracket 1 is provided on the electronic device.

In yet another possible implementation, as shown in fig. 3, a second adjusting portion 112 may also be provided on the base 11, where the second adjusting portion 112 is located on a side of the fixing portion 111 away from the adjusting member 12, and the base 11 may also be connected to the electronic device through the second adjusting portion 112.

The second adjusting portion 112 may be integrally formed with the base body 113, or may be separately formed. In this way, when adjusting the position of the stand 1 relative to the electronic device, the adjustment range of the stand 1 relative to the electronic device can be increased by the second adjustment portion 112 on the base 11.

As shown in fig. 3, the first adjustment portion 121 may be provided with a male screw, or the second adjustment portion 112 may be provided with a male screw, and in this case, the male screw as the first adjustment portion 121 and the male screw as the second adjustment portion 112 need to be provided with a screw structure having a uniform screw diameter and a uniform lead; alternatively, the first adjustment portion 121 may be provided in a male screw structure, and the second adjustment portion 112 may be provided in a cylindrical structure; alternatively, the first adjustment portion 121 may be configured as a cylinder, and the second adjustment portion 112 may be configured as an external screw; correspondingly, an internal thread matched with the external thread is arranged on the electronic equipment.
