At this time, the elastic reset member25will be compressed. When the end of the movable member533away from the fixed member532abuts against the bottom of the slot123, the movable member533is inserted in place. At this time, the hole5332of the movable member533corresponds to/matches with the limiting block232, and the push button22is located in the opening of the movable member533, as shown inFIG.9. Since the limiting block232is not blocked by the movable member533, under the reset action of the elastic reset member25, the limiting block232, the extension plate23and the push button22can move towards the rear inner wall of the left connector15to return to their initial position, and at this time, the limiting block232is restricted by the hole5332, as shown inFIG.9.

Next, the third supporting plate35is pulled away from the first supporting plate33, and then the second supporting plate34is rotated, for example, by 45 degrees, so that the third supporting plate35can be driven to rotate 45 degrees relative to the first supporting plate33, as shown inFIG.2andFIG.11. The end of the third supporting plate35away from the first supporting plate33is then in contact with, for example, a desktop, so that the bracket12can be supported by the third supporting plate35, the second supporting plate34and the first supporting plate33. When there is no need to support the bracket12, the second supporting plate34is firstly rotated to the initial position by rotation of −45 degrees relative to the first supporting plate33, so as to drive the third supporting plate35to rotate to its initial position relative to the first supporting plate33. Next, the second supporting plate34moves towards the bottom of the supporting cavity124, so as to drive the first supporting plate33and the third supporting plate35to move towards the bottom of the supporting cavity124until the first supporting plate33returns to its initial position. Finally, the third supporting plate35is pushed towards the bottom of the supporting cavity124until the third supporting plate35returns to its initial position. At this time, the first mounting column is located at the end of the sliding channel322away from the opening end of the supporting cavity124, and the end of the third supporting plate35away from the first supporting plate33is located in the opening end of the supporting cavity124.

In this embodiment, the numbers of the first sliding unit, the sliding channel322, the second sliding unit and the supporting channel342are two, and it should be appreciated that the number of the first sliding unit, the sliding channel322, the second sliding unit and the supporting channel342can be adjusted according to the actual situation.

As shown inFIG.6andFIG.7, the supporting assembly30further includes a sliding button36and a movable locking member37. The lower end of the bracket12is provided with a mounting groove125(refer toFIG.4) at a side, such as the right side, of the supporting cavity124, and the bottom of the mounting groove125is provided with an accommodating cavity126communicating with the supporting cavity124. The movable locking member37is arranged in the accommodating cavity126, and the sliding button36is arranged in the mounting groove125. The sliding button36partially extends into the accommodating cavity126and is connected with the movable locking member37. In this embodiment, the sliding button36has a first concave-convex structure362extending into the accommodating cavity126, and the movable locking member37has a second concave-convex structure372proximate to the sliding button36, which is clamped with the first concave-convex structure362, such that the sliding button36and the movable locking member37are connected or engaged. An end of the movable locking member37proximate to the supporting cavity124is approximately trapezoidal and is used to extend into the supporting cavity124to engage with a recessed portion353on a side of the third supporting plate35, which is proximate to the end of the third supporting plate35away from the first supporting plate33, as shown inFIG.10andFIG.11. An end of the movable locking member37away from the supporting cavity124is connected with the inner wall of an end of the accommodating cavity126away from the supporting cavity124by an elastic connecting member375, which is preferably a spring. Specifically, an end of the movable locking member37away from the supporting cavity124is provided with a groove, an end of the elastic connecting member375is arranged at the bottom of the groove, and the other end of the elastic connecting member375is arranged on the inner wall of an end of the accommodating cavity126away from the supporting cavity124. The sliding button36is slidable in the mounting groove125in a direction proximate to or away from the supporting cavity124, and the sliding of the sliding button36can drive the movable locking member37to move in the direction proximate to or away from the supporting cavity124relative to the bracket12. When the sliding button36is located at an end of the mounting groove125proximate to the supporting cavity124, an end of the movable locking member37proximate to the supporting cavity124extends into the supporting cavity124and engages with the recessed portion353on the side of the third supporting plate35. When the sliding button36is located at the end of the mounting groove125away from the supporting cavity124, an end of the movable locking member37proximate to the supporting cavity124is located in the accommodating cavity126.

In practical application, in an initial state, the sliding button36is located at the end of the mounting groove125proximate to the supporting cavity124, and the end of the movable locking member37proximate to the supporting cavity124extends into the supporting cavity124and engages with the recessed portion353on the side of the third supporting plate35to lock the third supporting plate35and the second supporting plate in the supporting cavity124. When the third supporting plate35and the second supporting plate34need to be pulled out of the supporting cavity124, the sliding button36is manually pulled away from the supporting cavity124, and the sliding of the sliding button36can drive the movable locking member37to move away from the supporting cavity124. When the sliding button36is located at the end of the mounting groove125away from the supporting cavity124, the end of the movable locking member37proximate to the supporting cavity124is disengaged from the recessed portion353of the third supporting plate35to realize unlocking, and the elastic connecting member375is in a compressed state. At this time, the third supporting plate35and the second supporting plate34can be pulled out of the supporting cavity124, and then the sliding button36can be released. Under the reset action of the elastic connecting member375, the movable locking member37and the sliding button36can be driven to move towards the supporting cavity124to return to their initial position. When the sliding button36slides away from the supporting cavity124and is located at the end of the mounting groove125away from the supporting cavity124, it is only necessary to push the third supporting plate35, the second supporting plate34and the first supporting plate33back into the supporting cavity124, and then sliding button36is released. Under the reset action of the elastic connecting member375, the movable locking member37and the sliding button36can be driven to reset, and at this time, an end of the movable locking member37proximate to the supporting cavity124engages with the recessed portion353of the third supporting plate35, so that the third supporting plate35and the second supporting plate can be locked in the support cavity124again.
